We are a family run business founded in 2007 and based in Welwyn Garden City, Hertfordshire. The company was initially established as a Saab Specialist. Later on, with the increased demand from our customers to look after their non-Saab-branded cars, the expansion of the business came along as a natural progression for us.

Now, apart from being a Saab Specialist, we are proud to have become a leading Mini and VW Audi Skoda & SEAT Specialists in Hertfordshire. At Cartech Welwyn, we also can provide servicing and repair for all makes and models. Cartech Welwyn is an MOT authorised testing centre, we carry out MOTs on all makes of cars in Welwyn Garden City and all Hertfordshire. 

Our mission is to keep the good reputation we have built through the years and continue to expand our base of happy and returning customers. All these changes would not have been possible without our valued customers, our passion for cars and focus on providing friendly yet professional customer service.


We have a modern, fully equipped vehicle workshop, computer diagnostic equipment to carry out diagnostics on your vehicle, and highly qualified experienced technicians. 

And if you want your car to be a bit different, at Cartech Welwyn we provide remapping services on both diesel and petrol cars. Our tuning software is very high quality and we offer lifetime warranty against software malfunctions. We are authorised agents for Racingline Tuning and parts (VAG Group tuning) and Avon Tuning (almost any make and model).

We guarantee that with us you will get the job done on your vehicle to the highest standard and in timely manner. Here at Cartech Welwyn we aim to be unique and to differentiate ourselves from our competitors by providing you detailed technical reports from our technicians, excellent customer service and competitive prices.

So if you are after an MOT, service, repair or remapping, with us you can rest assured that your car is in safe hands and you can enjoy a cup of tea/coffee on us while waiting or we can provide you with a courtesy car for the time of repair of your vehicle.


We look forward to meeting you!
