We have been around for a long time now here at A1 Diagnostics and are servicing customers vehicles from areas all over South Wales.

Here are a few photos of our independent garage.

We have seen our independent garage double in size now having 16 service ramps, two ADAS calibration bays, and a fully operational electrical bay. We don’t say this to boast how big we are or how big we have become, the point we want to convey is we are growing year on year, because of the first class service we offer our customers.

What does this first-class service look like. We pride ourselves on price, reliability, and quickness of service. We get to the heart of the issues with your vehicle, why are we so reliable in finding vehicle faults, because we have all of the latest vehicle tech needed to find exact faults, fixing them at the first attempt.

This is why customers keep coming back, because we save them time and money, and they know when they leave their vehicle with us they know it is in the safest of hands with our experienced mechanics.

Our mechanics and vehicle service advisors have a collective experience of 75 years, they have grown up in the vehicle service trade, this is why they are so reliable they know what they are talking about getting to the heart of the issues with your vehicle.
