EXCELLENT Based on 88 reviews Posted on Google Beth SoperTrustindex verifies that the original source of the review is Google. Fantastic service! Mini Cooper went in with what I thought was one issue but actually turned out to be quite a fair bit more… despite the work being far more than I had originally thought Joe was super quick and efficient and diagnosed and fixed all issues. He even sent across a video when the car was up on the ramp, talking us through the problems and showing us so we had an understanding of what was going on. Joe was super friendly and very professional, especially as a young woman it’s never a task I look forward to going to a garage…but Joe was really lovely and made the whole thing very straight forward. My mother in law works at a local school and had mentioned his garage after taking kids there for a show and tell day as he was wonderful to the children too. Top guy and I would recommend his garage to anyone! Diolch 🌟🌟🌟🌟🌟Posted on Google Stuart WatkinsTrustindex verifies that the original source of the review is Google. Great service from Joe. Managed to fit my car in at short notice, gave a fair quote before work started and sent video update to show the failed parts in situ. Thanks again, would highly recommendPosted on Google aly wongsterTrustindex verifies that the original source of the review is Google. 10/10 can’t fault joey and his efforts to do a good job and keep the customer updated in the loop. Did all the work I needed quick and with ease and for a reasonable pricePosted on Google Peter JamesTrustindex verifies that the original source of the review is Google. I booked my Jaguar F-Pace in for a service and I found Joe to be professional from start to finish. He got to work on the car immediately and sent me a detailed video of everything that needed doing ie. replacement of brake discs/pads, filter, oil etc. He also sent me a clear figure of cost before starting so there were no hidden extras. Later, I received and updated recording showing all the works completed. The car was then ready to be picked up on time. Joe is friendly and honest with a nice demeanour and I would highly recommend! Thank you.Posted on Google Lizzie 122Trustindex verifies that the original source of the review is Google. I messed up date of my MOT and Joe squeezed me in 2 days later. What an ace. I love that he collects car and drops it back and lets me know what's happening and discusses options. He is punctual, presentable and really personable. He was recommended to me by my brother in law and now my family also use him. What a trustworthy mechanic and all round good guy. Would recommend highly.Posted on Google Ti feeTrustindex verifies that the original source of the review is Google. 1st service at Law-Fix today for my mini hatch. Did a full service which cost £200 plus vat. Very accommodating and explained all he did and even sent a whatsapp video showing tyres all round as id asked him to check for me. Lovely guy. Highly recommend. Will go back for sure.Posted on Google Arosh WijepalaTrustindex verifies that the original source of the review is Google. I was recommended Law-Fix by a friend when I was having issues with my car's air conditioning, and I couldn't be happier with the service I received. From the moment I first called Joe to the completion of the work, he was incredibly polite, professional, and genuinely helpful. His customer service is absolutely top-notch and easily among the best I've experienced. During our first conversation, Joe took the time to explain the possible causes of the issue I was experiencing and the different approaches they could take to diagnose and fix it. When I brought the car into the garage, he once again walked me through exactly what they were going to do, explaining everything in detail in a friendly, approachable manner that immediately put me at ease. Throughout the repair process, Joe kept me updated on the progress, which I greatly appreciated. I had actually experienced this same issue before, and Joe was able to explain what may have been done incorrectly during the previous repair, giving me confidence that the problem was being properly addressed this time. Joe is an amazing human being—friendly, courteous, approachable, and clearly passionate about helping his customers. On top of that, their charges are very reasonable, especially considering the level of service and expertise provided. This has genuinely been the best experience I've had with a garage so far. I won't be going anywhere else for my future car repair needs. I would absolutely recommend Law-Fix to anyone looking for honest, knowledgeable, and customer-focused service.Posted on Google Charith BandaraTrustindex verifies that the original source of the review is Google. ⭐️⭐️⭐️⭐️⭐️ 100% Highly recommended! I found Law-Fix Automotive after doing my own research online reading through reviews carefully before choosing where to take my car and I'm so glad I did. It absolutely lives up to everything people say about it. Josef and his dad were both incredibly welcoming, professional, and genuinely passionate about their work the kind of father-and-son team that makes you feel like you're in the best possible hands from the moment you walk in. The service itself was top-notch, but what really set them apart was something I've never experienced at any other garage: Josef kept me updated throughout the entire job with real-time video updates. No waiting around wondering what's happening with your car he sent video footage showing exactly what was being done and why. It felt completely transparent and honest and gave me real peace of mind. The whole experience was friendly, efficient, and stress-free. It's rare to find a garage where the technical skill matches the customer care so perfectly. Law-Fix Automotive has earned a loyal customer in me. If you're searching for a garage, you can truly trust do your research, read the reviews, and you'll keep landing on the same answer: this place. Highly recommended 👌☺️Posted on Google Andrew JoyceTrustindex verifies that the original source of the review is Google. Joe was absolutely brilliant. He fitted me in with very short notice.

A healthy catalytic converter protects both your vehicle and the environment. Its primary role is to convert harmful gases such as hydrocarbons, nitrogen oxides and carbon monoxide into less harmful emissions before they are released into the atmosphere.
If your converter isn’t able to perform its function properly, your car will fail its MOT, which can lead to more serious issues down the line if not addressed promptly. It’s for these reasons that you should book in with a professional garage like Lawfix Automotive the moment you experience any issues with your converter.
Here are some typical signs that your catalytic converter is struggling to perform its functions within your vehicle:
Poor engine performance – noticing slower acceleration or just general decreased engine performance all around.
Check engine light – The Engine light is coming on on your dashboard.
Bad smell – A bad smell coming from your engine, which can sometimes smell like rotten eggs.
Failed MOT – usually manifests as your vehicle failing an emissions test
If you notice any of these signs, give us a call straight away and one of our friendly mechanics will be able to advise on the best course of action. We will likely ask you to bring down your vehicle so we can inspect it to determine the root cause of the issue! We won’t charge a penny for our services unless you have agreed to a price!
