MOT Cardiff

No.1 For Cardiff MOTs
Contact A1 Diagnostics

A1 Diagnostics is Cardiff’s No.1 VOSA approved MOT test centre, helping to keep thousands of vehicles of all shapes and sizes roadworthy for the right price. When you bring your car or commercial vehicle to our MOT centre, you can rest assured it’s in the safest of hands.


With years’ of experience in the motor trade, our trusted testing centre guarantees competitive prices for MOT testing on everything from family cars to vans, commercial vehicles and more.

An MOT is a test of your vehicle’s safety, roadworthiness and exhaust emissions. It is your responsibility, as the vehicle’s owner, to make sure an MOT is performed every year. During the MOT, we test the vehicle’s lights, electrical equipment, brakes, suspension, steering, tyres, seatbelts, exhaust and chassis to make sure it is safe for use on UK roads.

What makes A1 Diagnostics Cardiff’s No.1?

The state-of-the-art equipment we use to test your vehicle’s roadworthiness allows us to pinpoint problems other garages could miss. This helps to save on the cost of more expensive repairs further down the line.


As well as carrying out the MOT test, we can also repair the majority of faults straightaway, so you can get back on the road and on with your day. We also stock a huge number of parts for all major vehicle types, which means in many cases we do not need to order parts in.

If your car does fail its MOT first time around, we can make the necessary repairs there and then, before retesting your car for free. At A1 Diagnostics, this is all part of our MOT service.

MOT testing at the right price

We charge a transparent, fixed price with no hidden costs, delivering a cost effective service without compromising on quality. We also have a class 4 and class 7 MOT test lane, which allows us to service a wide range of vehicle types, including goods vehicles up to 3,500kg.

Our MOT centre costs:

• £54.85 for cars

• £58.60 for vans and trucks
