What does a car service include?

MOT test classes

Unsure which MOT class your vehicle would belong to? Our dedicated guide on MOT test classes will advise you which class your vehicle would be categorised into, and what types of vehicles are covered in each of the classes.

What MOT class is my vehicle?

When your vehicle has its annual MOT, it will be categorised into one of eight MOT classes. The eight MOT classes are:

Class 1:

Motorcycles, with or without side cars (with an engine size up to 200cc)

Class 2:

Motorcycles, with or without side cars (with an engine size over 200cc)

Class 3:

  • 3-wheeled vehicles (over 450kg of unladen weight)
  • Motor caravans
  • Cars (of up to 8 passenger seats)
  • Quads (max unladen weight 400kg – for goods vehicles and max net power of 15kb)
  • Private hire and public service vehicles (up to 8 seats)
  • Dual purpose vehicles
  • Private passenger vehicles and ambulances (9-12 passenger seats)
  • Ambulances and taxis
  • Goods vehicles (up to 3,000kg design gross weight)

What people are saying about us...

  • Great service!! Staff went over and beyond to sort out the problem with my vehicle.

  • Yes it was a really good experience. The only downside was that there was no seating for me. I had to sit outside on the boundary wall. Waiting for my vehicle. Otherwise it was a pleasant experience.
