Class 4 or Class 7 MOT? Here's the Difference
14 January 2026
If you've driven past our two Clydebank sites, you'll have noticed one tests "Class 4" and the other tests "Class 7". It's not a pricing tier, it's a DVSA classification based on the type of vehicle.
Class 4: cars, taxis and light vans
This covers the vehicles most people bring in: cars, motorcaravans, and light vans and goods vehicles up to 3,000kg design gross weight, plus private-hire and hackney taxis. We test Class 4 at our Domestic Centre on Glasgow Road, from £45.
Class 7: vans and light commercials over 3,000kg
Class 7 covers goods vehicles between 3,000kg and 3,500kg design gross weight, essentially the bigger Transit-style vans and light commercials that trade and fleet customers rely on. We test these at our Commercial Centre on Caledonia Street, from £55. It's a dedicated bay so we're not trying to squeeze a van test in between family cars, which keeps turnaround quick for people who can't afford a day off the road.
Not sure which one you need?
As a rule of thumb: if your vehicle's plated weight is under 3,000kg, it's Class 4. Over that, up to 3,500kg, it's Class 7. If you're still not sure, drop your registration into the quote tool on our MOT page and we'll point you to the right centre, or just call whichever one is closer and we'll sort it.
Both classes cover the same statutory checklist underneath, brakes, lights, steering, suspension, tyres, exhaust and emissions. The class just determines which of our two Clydebank sites has the right bay and equipment for your vehicle.
