Why Your Business Can’t Afford to Miss Its MOT: Class 4, 5 & 7 Testing Explained

Written By Gerard Hall

Keep Your Vehicle Compliant – and Your Business Moving

When it comes to keeping your vehicle road legal and safe, an annual MOT test is essential. But not all MOTs are created equal — especially for businesses running vans, minibuses, or commercial fleets. Understanding the differences between Class 4, Class 5, and Class 7 MOTs helps you book the right test and avoid unnecessary delays.

What’s the Difference Between Class 4, 5 and 7 MOTs?

🚗 Class 4 MOT – For Most Cars and Light Vans

The Class 4 MOT is the most common in the UK. It covers standard passenger vehicles with up to 8 seats and light vans up to 3,000kg gross vehicle weight (GVW). If you drive a Maxus Deliver 9, Ford Transit Custom, or similar-sized vehicle, this is likely the test you need.

🚌 Class 5 MOT – For Minibuses and Larger Passenger Vehicles

If you operate minibuses, ambulances, or vehicles with 13+ passenger seats, you’ll need a Class 5 MOT. These tests often include Class 5A, which involves checking any specialist seatbelt installations. Not all centres offer this service – so be sure to book with a provider who does.

🚛 Class 7 MOT – For Larger Vans and Commercial Vehicles

Got a van or truck between 3,000kg and 3,500kg GVW? That falls under the Class 7 MOT. This test is essential for vehicles like the Isuzu Grafter or other rugged commercial workhorses used in the building and utility trades.
