Average net circulation July 2024 to June 2025 22,797 Let’s meet Since we wrapped up our last edition, I’ve been meeting more of the aftermarket community, both in person and virtually. One standout opportunity was the chance to join Laser Tools’ 50th anniversary celebration, which took place late in March. It was an excellent day, and chatting with the team about how tools are evolving to meet the ever-growing complexity of today’s vehicles brought me back to my younger days as an enthusiastic but very much amateur mechanic working on my own vehicles. The trigger was seeing the Gunson Colortune in the company’s display suite (Gunson became part of Laser Tools’ parent company, Tool Connection, around 20 years ago). It’s a fantastically simple tool, but at the time, it was invaluable for adjusting the fuel mixture in carburettor-fuelled engines. It is still available today, but, of course, now most vehicles require a far more sophisticated approach to achieve similar results. And Laser Tools has had to keep up with this evolution, something it has done well, remaining a successful business for five decades. On pages 10 and 11 in this issue, I report on the anniversary and a conversation I had with the company’s Technical Director about how Laser has maintained its success throughout the period, keeping up with the everchanging demands of the vehicle parc and those maintaining it. Another highlight of the last few weeks was a conversation with Barry Lawson of Lawson Autotech. Barry’s business has gone from treading water just a few years ago to significant growth, winning a Top Garage award, and even launching an event to bring together aftermarket businesses in his native Scotland and the north of England. It’s a fascinating story and an inspiration to other independent garages looking to kick-start their growth, which you will find on pages 16 and 17. Looking ahead, this issue also includes a preview of the upcoming UK Garage & Bodyshop Event, which starts on page 24. This promises to be a great opportunity for the aftermarket sector to come together and see what’s new, and in our preview, we also outline a selection of the highlights to be found on the exhibition floor. And, of course, the Aftermarket team will be there, on stand K58, and I’ll be touring the exhibits. If you’d like to meet up over the two days, please get in touch via chris@aftermarket.co.uk. That’s just a taster of what we have in the following pages; there’s plenty more news, views and technical features. I hope you enjoy the issue. Chris Callander Editor

News 6 www.aftermarketonline.net MAY 2026 At its annual Autocentre of the Year awards, held on 26 March at the Concorde Centre in Manchester, Servicesure recognised the UK’s highest-performing independent garages, with Liverpool-based Ashwell Motors named Best Overall Garage. The awards underline the continued evolution of the independent sector, as garages invest in new technologies, expand fleet relationships and raise operational standards to meet changing vehicle parc demands. The 2026 Customer Service Award went to EAC Telford, as did the EV Garage of the Year award. The Fleet Garage of the Year was Magnet Autos , and Supplier of the Year was awarded to YUASA. The Regional Garage of the Year winners were: North West: Ashwell Motors, North East: Charlie Taylor Garage Services, Midlands: Elite Vehicle Repairs, South West: Cleevely Electric Vehicles, South East: Swanley Garage Services, Scotland: Balmoral and Crown, and Wales: GP Motors. All regional winners were considered for the overall title, with Ashwell Motors selected as Best Overall Garage. New industry report reveals key trends shaping the UK aftermarket BookMyGarage has published its first industry report, drawing on its own platform data alongside garage market insights to provide a data-led view of how UK motorists are booking MOTs, servicing and repairs and what this means for garages. The BookMyGarage 2025 Aftermarket Insights Industry Report combines data from millions of real booking interactions with surveys of garage owners and motorists, delivering a snapshot of trends and changing consumer behaviour as well as workshop demand across the UK aftermarket. Alongside its demonstration of the £134m worth of work generated for garage partners by the platform, the report highlighted several interesting findings. On the topic of MOT pricing, 62% of garage owners who responded said they wanted to see an increase in the cost of an MOT, with over two-thirds favouring a price between £55 and £65. While 64% of the drivers surveyed had not used a mobile mechanic before, 68% said they would consider it in the future. The analysis of pricing also highlighted some interesting trends. While some standard repairs, such as clutch and brake replacements, saw their average costs rise in line with inflation over the last 12 month, there were some which were lower than last year. Other areas covered by the report include trends in the age and types of vehicles booked on the platform, and the business outlook and challenges of its garage partners. The status of EV bookings and garage capacity to take on this work is also covered, as is the platform’s users’ search patterns, which show, for example, that drivers are increasingly prioritising convenience with ‘distance’ being the primary motivator for drivers searching on the platform rather than price. Commenting on the launch of the report, Karen Rotberg, Co Founder of BookMyGarage, said. “This report marks an important milestone for us. For the first time, we’re sharing our platform data and garage market insight to help the industry better understand how driver behaviour is evolving - and where the real opportunities lie for garages.” The full report is available to view and download at bookmygarage.com/forgarages/industry-report/ Servicesure recognises its network’s champions Compressed air solutions specialist Champion is heading on tour, with a roadshow that will bring its compressors direct to customers across the UK and Northern Ireland, as well as the Republic of Ireland, France, Belgium and the Netherlands. Customers can request a visit from a purpose-built vehicle carrying the company’s equipment anytime between March and August 2026. The vehicle will include the Champion FM11, which the company says is one of the most compact compressors on the market, with low noise levels, allowing installation at the point of use. Also demonstrated will be the small and compact Hydrovane HV01 compressor, which is suited to light industrial and workshop applications where the compressed air outlet needs to be situated close to the application.

News 8 www.aftermarketonline.net MAY 2026 Volkswagen Group brands have no plans to commit to SERMI Unless you have been living under a rock, you will be well aware that the new SERMI scheme has officially gone live in the UK, something Aftermarket reported online (tinyurl.com/344jehw6) on 1 April, as it came into play. While the scheme had the backing of 22 manufacturers on the go-live date, we noted at the time that some brands were not supporting it, notably Volkswagen Group brands. Having been in touch exclusively with a representative of the Volkswagen Group in the UK, Aftermarket can reveal that there are currently no plans for the group’s brands to join the scheme. A spokesperson for the Volkswagen Group told Aftermarket magazine: “We would like to clarify that the introduction of SERMI in the UK is not mandatory for either vehicle manufacturers (OEMs) or independent operators. As SERMI’s launch in the UK is on a voluntary basis, it does not fall under any UK legislative framework. “Volkswagen Group brands already operate a well-established, accessible and comprehensive process for qualifying operators and technicians to obtain the security-related information they require to carry out their business activities. At this time, Volkswagen Group brands have no plans to change the mechanism through which independent operators access this information. “Accordingly, SERMI accreditation will not replace or alter the existing access rights held by current users.” Key to this statement is that it reflects the Volkswagen Group’s position “at this time”, so there is scope for this decision to be reviewed. Indeed, there have been calls from within the industry for SERMI to be made mandatory, as it is in the EU, which would force the Group to change its position. Of course, not all independent garages need to sign up to SERMI, notably those that are not involved in the repair of security-related systems. But those that do, and work exclusively with Volkswagen Group brands, will not need to make any changes – for the time being.

Spotlight 10 www.aftermarketonline.net MAY 2026 Fifty years of tool evolution With Laser Tools recently celebrating its 50th anniversary, Aftermarket’s Editor, Chris Callander, spoke with the company’s Technical Director, Mark Softley, about how the world of automotive tools has changed in the years since the company was formed. As part of celebrations to mark its 50th anniversary, Laser Tools has launched Future 50, an initiative designed to support aspiring young mechanics in their first steps into the automotive aftermarket, and has also introduced 50 new specialedition tools. Future 50 offers garages the opportunity to nominate their existing apprentices for the new initiative. The chosen Future 50 each receive a Laser Tools Apprentice Tool Kit, complete with a range of high-quality products, and have the chance to win one of three pairs of VIP racing tickets to a British Touring Car Championship race at Brands Hatch on 11th October, with advice, training and accreditation opportunities also to be announced. The 50 new tools, each complete with a 50-year warranty, were unveiled during a special episode of the ‘Laser Live’ videocast broadcast on Laser Tools’ dedicated YouTube channel in March this year, and are featured in a special edition of Tool Saver, Laser Tools’ dedicated parts catalogue. Laser Tools started as a business in 1976, when its founder, the late Martin Smith, began selling automotive tools from a market stall in Leamington. From those humble origins, it has grown to become one of the most respected brands in the automotive sector. Over the past five decades, cars, and in turn the tools needed to maintain them, have become increasingly complex. So I spoke to Mark Softley, Technical Director at Laser Tools, to find out in more depth how the landscape has changed in terms of the tools technicians need and their expectations of tool manufacturers. Chris Callander: Mark, how has the role of specialist tools evolved over the past 50 years as vehicle technology has become more complex? Mark Softly: Fifty years ago, cars like the Ford Escort ruled our city, and you didn’t need any special tools to work on them. Today, almost every make and even individual models require special service tools (SSTs). Around that time, we also started to see some vehicles using special fixings like Torx-headed bolts and screws, and now they are everywhere. Then, as engines became more advanced and emissions rules tightened, timing jobs went from ‘line up the marks and pop a pin in’ to using digital gauges to measure exact angles. Developments in every area of the vehicle have led to ever-increasing numbers of SSTs being required. Chris: So, looking back over the past five decades, what would you say have been the most significant turning points in the automotive aftermarket? Mark: At Laser Tools, we focus primarily on the mechanical aspects of the vehicle. While automotive electronics have advanced at an extraordinary pace, especially considering that fifty years ago most cars had virtually none, the mechanical side has had to evolve alongside them. In fact, many electronic innovations have directly reshaped mechanical design. Closedloop fuel injection, OBD-II, ABS, ADAS and electrification are all milestones that have had a knock-on effect on the mechanical side of the vehicle as a whole. New tooling is required, from a special screwdriver to adjust a camera angle to electronically-defined engine timing kits and ADAS targets, etc. Keeping up has never been simple, and for Laser Tools, it’s an ongoing mission. Electric vehicles (EVs) aren’t the end of the story; they’re just the next chapter in how vehicles keep changing. Chris: And how are these developments shaping the types of tools workshops now require? Mark: Even with electrification, cars haven’t stopped needing mechanical systems. EVs still have brakes, suspension, and all the usual chassis components, etc. Electronics need sensors or cameras to feed back data, and those sensors need to be set up and even adjusted. That’s where tools, and often SSTs, come in. Chris: Alongside the evolution of vehicles, how have the needs and expectations of independent workshops changed over time when it comes to tools and equipment? Mark: Independents really don’t have it easy. They are almost always the last to learn about new systems, procedures, and protocols, and OEMs often share far less information than they should. A new camshaft design, such as COD, can require an entirely new process or methodology, yet independents often only discover this when the vehicle is already on the ramp for service or repair. They will then come to us asking, ‘Do you Martin Smith founded Laser Tools under the name Smith’s Tools Keeping up has never been simple
Spotlight 11 www.aftermarketonline.net MAY 2026 make a tool for this?’ followed quickly by, ‘And how do we use it?’. These questions spark our research and lead to solutions that benefit everyone. Independents rely on us to know what tools they need and how those tools should be used. Fifty years ago, the expectation was very different: Independents already knew what they needed and how to do the job, because the systems and processes had barely changed in decades. Chris: What do today’s technicians value most in a tool, and how has this shifted compared with previous generations? Mark: Time is money, so saving time ultimately saves money. When we develop a solution that significantly reduces labour time but comes at a higher cost, customers have to weigh the cost–benefit ratio. If the time saved justifies the investment, then it is a nobrainer. Quality and ease of use also matter. Fifty years ago, there were fewer choices; today, the options are vast. OEM tools are expensive, and our customers want SSTs that perform the job effectively but at a lower price. That means we must design cost effective solutions that still deliver reliable performance. Cost is always a consideration. You may find tools elsewhere that look similar for less, but cheaper tools often lack the quality required. Quality does cost more. It’s worth remembering that if a tool fails, you lose not only the money you spent on it but also valuable time, and most of our customers understand that well. Chris: How do you see the growth of EVs changing tooling requirements and workshop competencies? Mark: The tool bag will not get smaller, but it is changing. While the internal combustion engine may gradually fade from the mainstream, it is being replaced by new systems that still require maintenance and occasional repair. Even though the average EV needs far less routine servicing, it is not maintenance free. Anything with moving parts will experience wear over time. Another key driver of demand is health and safety. Increasingly, we’re being asked to supply tools that are directly or indirectly led by safety concerns. At its core, our role hasn’t changed: we provide the tools needed to get the job done. As the industry evolves, we may need to broaden our portfolio and step into areas we may have previously overlooked, but the fundamental purpose remains the same. lasertools.co.uk The current Laser Tools team celebrating 50 years of business.

Business 13 www.aftermarketonline.net MAY 2026 Your supplier must treat you fairly Managing business energy costs in an uncertain market Following the recent increases in energy network costs, Ofgen’s Jemma Baker outlines some of the things to consider if your energy contract is due to be renewed. The price you pay for energy for your business can vary across suppliers and the type and size of your business, but covers a range of costs, including the wholesale energy cost (the cost to buy energy), network costs (the infrastructure to transport energy), and environmental costs (government decarbonisation schemes). Typically, wholesale costs are about 40% of your electricity bill and 60% of your gas bill, but exact percentages vary. In April 2025, network costs increased to upgrade energy infrastructure. Wholesale energy costs are volatile and will continue to be affected by the situation in the Middle East. Our understanding is that the majority of businesses are not currently exposed to immediate price increases, as contract lengths are starting to return to 3 to 5 years in length. However, if your fixed price contract is coming to an end, you will need to negotiate a new contract with your supplier. If your current contract is coming to an end, talk to your supplier about what options are available. If you have an energy broker, they can do this for you. Consider your options Ask suppliers what contracts are available and consider both short and long-term options. It may be better for you to temporarily stay on deemed or out of contract rates if the current longerterm contract offers are high. There are several things to be aware of, though. When considering your contract options, you should be aware that suppliers may require security deposits due to the higher risk of businesses defaulting on payments. Also, energy suppliers are not obliged to offer businesses a contract, and offers may be harder to find. You certainly shouldn’t feel pressured into signing a contract, and there is no cooling-off period, so do check the terms and fees beforehand. Plus, if you discuss a contract over the phone, you should ask for it in writing before agreeing to it. Keep in contact with your supplier Your supplier must treat you fairly and bill you accurately based on your meter readings. To ensure you are only paying for what you use, submit regular meter readings or get a smart meter. It is also important that you keep your contact details up to date so that you receive your bills. If you are having problems managing your bill, you should talk to your supplier or your energy broker. Your supplier can also offer you advice on reducing your bill. Ways to get help Managing energy for your business is just one of many competing demands. There is support available to help you, though. You can contact reputable energy brokers who can talk to suppliers for you, or trade bodies, consumer groups and charities who can offer detailed advice and support, and the Energy Ombudsman for small businesses can help if you get into a dispute with your supplier and you cannot resolve your complaint. If your dispute is with your energy broker, they will provide details of their redress scheme provider to contact. Finally, you could be eligible for financial assistance or schemes that help you reduce energy costs, and a good place to start your search would be tinyurl.com/4ce6fbp7. tinyurl.com/2vjkpyzt
Technical 14 www.aftermarketonline.net MAY 2026 Five tips for successful CAN Bus diagnostics CAN Bus can be tricky to diagnose, but by following five steps, you can make the process much easier, as Darren Quinn, from Mechanic Mindset, explains. When diagnosing a CAN Bus issue, it’s important to cover the basics; a ‘complex’ issue causing various problems with wipers, speed indicators, and warning lights could be caused by a simple blown 5-amp ABS fuse. Hence, in CAN bus diagnostics, starting with the basics and systematically eliminating common issues is an essential approach to problem-solving. Perform a function test To effectively diagnose CAN Bus issues, you need to understand your vehicle’s network topology. Understanding this is like knowing the road map of your car’s communication system. Your car’s different parts, like the engine, transmission, and even the wipers, need to talk to each other, just like friends using different languages. These friends communicate through a special box in your car called the ‘gateway’. When you know this network map, you can perform ‘function tests’ to check if everything is working as it should. For example, think about your car’s speed. This information needs to travel from the wheel speed sensor to ABS, then to various parts like the speedo, radio, the wipers, and more. The gateway helps translate this information into a language that each network understands. Sometimes, a test as simple as activating the turn signal indicator can feedback whether the CAN bus networks are communicating. The turn signal switch sends a message on the CAN bus, which is shared with all networks via the gateway. The body control module receives this message and activates the exterior lights. The instrument cluster receives this message and displays the green indicator light. Understanding the network map helps you know where to look and what to test. Full OBD scan Performing a full OBD (On-Board Diagnostics) scan is a crucial step in. It can help identify if there are any network problems. If your scan tool can communicate with various modules, it’s a good sign that the CAN network is functioning properly. However, if modules are missing or not responding, it might be an indication of a CAN Bus needing further investigation. Understanding your vehicle’s network topology and how it connects through the OBD connector is essential. Some vehicles have all CAN networks ending at the OBD plug, which can be handy for testing. But in some cases, only one network is available through the OBD plug. If you can communicate with all modules via the OBD, it suggests the network connected to the OBD plug is likely in good shape. When modules are missing or not responding, it’s crucial to check power supplies, grounds, and fuses before diving into more complex CAN Bus network troubleshooting. This step helps rule out common electrical issues that might affect the network’s operation. Multimeter checks Before reaching for the oscilloscope, use a multimeter to perform some initial checks. Important multimeter checks include: O Resistance check: With the battery disconnected, measure the resistance between the CAN High and CAN Low wires. The goal is to find a total resistance of 60 ohms. This doesn’t give you the complete picture of the network’s health, it’s more like checking the two ends of a bridge to make sure they’re connected. O Continuity check: This means ensuring that there’s a good electrical path between points. You can check for continuity between ground, power supply, or even between the two wires in the CAN Bus network. O Voltage check: For a high-speed CAN
Technical 15 www.aftermarketonline.net MAY 2026 network, you’d typically see around 2.6V on CAN high and about 2.4V on CAN low with the ignition switched on. However, these values may vary depending on the number of modules and network activity. If the voltages on both CAN high and CAN low are the same, it could indicate a short circuit (which should have been confirmed by your resistance check). If both voltages are at 0V, it might suggest a short to ground. If the voltages don’t look right, you could be dealing with an open circuit or a resistive short circuit. By using the multimeter for these checks, you can quickly identify basic issues such as open circuits, shorts, or abnormal resistances. Oscilloscope diagnosis When you’ve confirmed a network issue and the basics are covered, it’s time to bring out the oscilloscope. An oscilloscope provides a more in-depth analysis of the CAN Bus signals. Here’s what it helps you achieve: O Visualising CAN Bus signals: CAN Bus communication involves electrical signals transmitted as voltage levels on the CAN high and CAN low wires. An oscilloscope allows you to visually represent these voltage signals over time, which provides a clear and detailed view of how data is being transmitted and received on the network. O Identification of faults: An oscilloscope can help you spot anomalies in the CAN Bus signals. It can reveal issues like short circuits, open circuits, voltage spikes, or noise in the network. By examining the waveform, you can identify irregularities which are essential for troubleshooting network issues. O Detection of intermittent faults: Many CAN Bus problems are intermittent, occurring sporadically. The oscilloscope is invaluable for spotting these and helping to pinpoint the root causes. O Resistive fault detection: Sometimes, issues are related to resistive faults, such as high resistance in connectors or wires. An oscilloscope can reveal voltage drops or fluctuations that may indicate resistive problems in the network. O Differentiating high-speed and lowspeed networks: CAN Bus networks can operate at different speeds. An oscilloscope enables you to distinguish between high-speed and low-speed networks by analysing the waveform characteristics. This information is vital for diagnosing the correct part of the network. An oscilloscope is a powerful diagnostic tool for CAN Bus issues, offering real-time visibility into the network’s electrical signals. It helps you identify problems, locate faults, and ensure that the CAN Bus communication adheres to the required standards. Find and isolate CAN Bus faults Diagnosing a network issue is a process of elimination. Start by revisiting any available evidence, such as previous repair history, accident damage, or other work on the vehicle. This information can provide valuable clues for where to begin the diagnosis. If no specific leads are available, you may have to methodically test the network from one end of the car to the other, prioritising the easiest access points. The first step in the diagnostic process is to individually disconnect modules from the CAN bus network. This straightforward procedure can help identify if a specific module is responsible for the issue. It’s a relatively simple test, though some modules might be challenging to access. If the problem persists even after disconnecting modules, it indicates a problem with the wiring. The next step involves locating connectors in the wiring loom, ideally a midpoint in the network, and disconnecting them to determine if the fault lies on one side of the car or the other. In cases where there aren’t any connectors, you might need to trace, cut, and repair wires. Some vehicles use splice points and non-standard joints that can be challenging to locate, so having the workshop data and wiring diagrams available is very important. Sometimes the most complex issues have surprisingly simple solutions. Always start by checking the basics, like fuses and connectors, as these can often be the source of CAN Bus problems. And don’t forget to document your findings, as this can help you track down and resolve issues more efficiently. www.mechanicmindset.com Understanding the network map is essential for CAN bus diagnostics.

Garage Focus 16 www.aftermarketonline.net MAY 2026 What most independent garages miss – and how one got it right In this month’s Garage Focus, Chris Callander spoke with Barry Lawson of Lawson Autotech about how his business went from “plodding along” to claiming a Top Garage accolade and then inspiring others to follow suit. All across the UK, there are garages with an incredibly similar story. Technically, they are very capable and working extremely hard, but they are simply not moving forward in the way they would like. That was certainly the case for Lawson Autotech, based in the Scottish town of Larbert. When I caught up with Barry Lawson, he was refreshingly open about the journey the business has been on. It is a story that begins not with rapid growth or a clear strategy, but with a long period of simply keeping things going. Lawson Autotech was established in 1983 by Barry’s father. By the time Barry joined in 2001, it was a wellestablished local garage, but like many similar businesses, it was operating on experience and routine rather than any defined plan. For years, the business “plodded along”, as Barry put it. There had once been a larger team, but over time, numbers had reduced, and by the time Barry began to take a more active role, it had effectively become a two-man operation again. Looking back, he admits that period was characterised by a lack of direction. “There was no real vision,” Barry said. “We were doing a good job for customers, but we weren’t really moving forward.” The turning point was not a single dramatic event, but a gradual realisation that something was not right. Barry describes a moment familiar to many garage owners: working long hours, putting everything into the business, and then looking at what was left at the end of the year. “It was a wake-up call,” he explained. “We were working flat out, but what we had left to share between us just didn’t reflect the effort going in.” The value of talking to others A key shift came in 2018, when the business joined the DPF Network, a national network of independent DPF specialists. That decision exposed Barry to a much wider peer group, and, crucially, to businesses that were achieving far more. “It was an eye-opener,” he added. “You start speaking to other garages across the UK, and you realise what’s actually possible.” This is a point Barry returned to repeatedly. For him, one of the biggest barriers in the independent sector is not technical capability, but isolation. Many owners simply do not talk to others in the trade in any meaningful way. And when they do, they do not always act on what they hear. “There’s a difference between asking for advice and just moaning about a problem,” he continued. “If you’re going to ask, you’ve got to be prepared to listen, and then actually do something as a result.” That willingness to listen and, if needed, accept some uncomfortable truths became a defining feature of Lawson Autotech’s transformation. A target to aim for The next step in the journey came in 2019, when Barry attended the Top Garage Awards for the first time. Initially, it was simply a day out with others from the DPF Network. But the experience had a lasting impact. Hearing the stories of other finalists and seeing what high-performing garages looked like in practice provided a clearer benchmark. “It gave me something to aim for,” Barry said. “You look at it and think, if Barry Lawson with members of the Lawson Autotech Team collecting the Top Garage (7-9 Employees) award
Garage Focus 17 www.aftermarketonline.net MAY 2026 they can do it, why can’t we?” From that point, the awards became more than just an event. It became a target. What followed was not an overnight transformation, but a structured effort to improve; entering the competition, falling short, learning from the experience, and going again. Barry used each attempt as a learning exercise, identifying weaknesses and gradually implementing improvements. And it worked when, at the third attempt, Lawson Autotech came out on top as the winner of the 7-9 employee category at the 2025 Top Garage Awards. Building the foundations for growth A significant part of the business’s improvement came down to structure and recognising personal limitations. Barry is candid about the fact that one of the biggest changes had to happen in himself. “You’ve got to admit where you’re weak,” he explained. “Then either learn how to improve, or bring in people who are strong in those areas.” That thinking led to Laura Guild joining the business in 2020. With experience from managing larger teams, Laura introduced processes and operational discipline that had previously been lacking. And, over time, that allowed the business to grow from two people to a team of ten. Of course, with growth came new challenges. Managing people, maintaining standards and ensuring consistency required a different approach. This is where standard operating procedures (SOPs) became critical. “When you’re small, you think you can just tell people what to do,” Barry admitted. “But as you grow, that doesn’t work. It has to be written down. It has to be consistent.” For many garage owners, this is a key barrier to growth. What works for a two- or three-person operation does not scale. Without clear processes, growth quickly creates confusion. Closing the circle One of the most interesting developments since then has been Barry’s decision to give something back to the sector that helped shape his own journey. Earlier in 2025, Lawson Autotech launched its own industry event, the Thistle Auto Revival conference. The idea is simple: bring garage owners together, create a space for open discussion, and share practical experiences that others can learn from. The first event attracted over 100 attendees, with a strong mix of Scottish and English businesses making the trip. For Barry, it represents something of a full-circle moment. Having once been inspired by conversations at industry events, he is now creating those opportunities for others. “It’s about showing people that they’re not alone,” he added. “And that they can do this too.” Thanks to the success of the first event, plans for the next event have recently been released, taking place in Alloa on 6 February 2027. Lessons for the wider sector What makes Lawson Autotech’s story particularly valuable is that it is not built on a single breakthrough idea or piece of technology. Instead, it is the result of a series of relatively straightforward but often overlooked decisions: Talking to other businesses and learning from them, being honest about weaknesses, putting structure and processes in place, building the right team, and, perhaps most importantly, taking action. None of these steps are unique. All are within reach of most independent garages. The difference, as Barry’s experience shows, lies in actually doing them. And it demonstrates that for those willing to take that step, the potential is there.
