Van MOT Explained: Class 4 vs Class 7

Book the wrong MOT class for your van and you will be turned away at the door, because not every garage can test every van. The split between Class 4 and Class 7 trips up van owners constantly, so here is exactly which test your van needs, when it needs it, and how to pass first time.

Class 4 or Class 7: it is all about design gross weight

The MOT class for a van depends on its design gross weight, the maximum the vehicle is built to weigh fully loaded, shown on the VIN plate and V5C:

• Class 4 covers cars and goods vehicles up to 3,000 kg design gross weight. Small and many medium vans, such as compact city vans and lighter short-wheelbase panel vans, sit here.
• Class 7 covers goods vehicles from 3,000 kg up to 3,500 kg design gross weight. This catches most long-wheelbase and high-roof large panel vans, the workhorses of delivery and trades fleets.

Anything plated above 3,500 kg has outgrown the MOT system entirely and falls under the annual test regime for heavy vehicles, which we cover in our guide to the HGV annual test.

Why the class matters when booking

Class 7 lanes need longer ramps, stronger lifts and roller brake testers rated for heavier vehicles, so plenty of ordinary MOT stations only hold Class 4 approval. Always confirm the garage tests Class 7 before booking a large van in, and expect slightly fewer stations and a slightly higher maximum statutory fee than for Class 4. The timing rules are the same for both classes: first MOT at three years old, then every year.

What van MOTs actually fail on

Vans fail more often than cars, and mostly on things a ten-minute check would catch. The perennial offenders are:

• Lights. Blown bulbs and misaimed headlamps remain the single most common failure, and the cheapest to prevent.
• Tyres. Worn shoulders from kerbing and underinflation under load, plus damage from site work. Check depth across the whole width, not just the middle.
• Brakes. Hard-worked vans eat pads and discs, and imbalanced brakes fail on the rollers even when the pedal feels fine.
• Suspension. Broken springs and worn bushes, aggravated by permanent heavy loads.
• Wipers, washers and screen damage in the driver’s sweep area.

A hard-working van that only ever gets looked at when the MOT is due is a van that fails. A simple monthly once-over, borrowing the habits of the professional daily walkaround check, keeps most of these failures off the sheet.

Preparing so you pass first time

A week before the test: run every light with someone walking round, check tyres for depth and damage, top up washer fluid, test the horn, clear the dash of warning lights, and remove anything blocking the tester’s access to seatbelts and doors. Persistent warning lights for ABS, airbags or emissions are failures in themselves, so get them diagnosed before test day rather than hoping. If you are buying a used van, its MOT history is free to check online and tells you plenty about how it has been kept, a point we expand on in the used van inspection checklist.

Bringing it together

Check the plate, book the right class at a garage that can take it, and spend twenty minutes on preparation: that is the whole game. A first-time pass keeps the van earning and avoids retest hassle.

Frequently asked questions

How do I know if my van needs a Class 4 or Class 7 MOT?

Check the design gross weight on the VIN plate or V5C. Up to 3,000 kg is Class 4; between 3,000 kg and 3,500 kg is Class 7. The model name alone is not enough, because many vans are sold in variants that fall either side of the line.

When does a new van need its first MOT?

Three years after first registration, the same as a car, and annually after that. Vans plated over 3,500 kg follow the heavy vehicle annual test instead, which starts at one year old.

Can any garage MOT a Class 7 van?

No. Class 7 requires approved equipment sized for heavier vehicles, so fewer stations offer it. Always confirm Class 7 approval when booking a large panel van, or you may be turned away on the day.
