Payload and gross vehicle weight — the check a car buyer never needs
This guide covers payload and gross vehicle weight, which MOT class applies, why a history check still matters, and a short in-person checklist. It's part of our guide to car history checks — most of what applies to a car applies to a van too, with the additions below.
Every van has a gross vehicle weight (GVW) — officially the "maximum authorised mass" — which gov.uk defines as "the weight of a vehicle or trailer including the maximum load that can be carried safely when it's being used on the road." That figure is set by the manufacturer and shown on the vehicle's weight plate, not something you calculate yourself.
Payload is what you actually get to use. It's the GVW minus the van's own unladen (kerb) weight — fuel, driver, passengers and cargo all come out of that allowance. Go over it and you're not just risking a fine: you're driving an overloaded vehicle, which affects braking distance and handling, and can invalidate your insurance if you have an accident while over the limit.
Before you buy, check the weight plate (usually inside the driver's door frame or under the bonnet) against what you actually need to carry — not just the headline payload figure quoted in the original brochure, which assumes a base-spec van with no extras.
MOT Class 4 vs Class 7 — which applies to this van
Most vans are tested the same way as cars — but not all of them, and it depends on weight, not the word "van" on the listing. Per gov.uk's MOT inspection manual:
- Class 4 covers cars, motor caravans, and light goods vehicles up to 3,000kg design gross weight — most small-to-mid-size vans (a standard-length Transit or Transit Custom, for example) fall here.
- Class 7 covers goods vehicles over 3,000kg and up to 3,500kg design gross weight — bigger panel vans (long-wheelbase Transits, Sprinters, Crafters) fall here instead.
This isn't just paperwork trivia: Class 7 tests need a heavier-duty ramp and brake tester than many general garages have, so not every MOT centre can test a Class 7 van — worth checking before you commit to a garage for future MOTs.
A Class 7 test currently costs slightly less than a Class 4 test (£58.60 maximum, against £64 for Class 4, at the time of writing — gov.uk's fee table is the one to check, since both figures move).
Why a used van needs a history check just as much as a car
The same risks apply — outstanding finance, insurance write-off category, mileage discrepancy, stolen reports — and worth checking the same way you would for a car, via a history check against the registration number. Our Comprehensive check is built around exactly this data; see the sample report for what it looks like. If you're unsure whether a specific van's registration is supported, contact us before you rely on the result — see the FAQ below.
Prior use matters more for a van than a typical private car. Many used vans have spent time as courier, rental or trade vehicles — jobs that mean more miles, harder wear on the load area and drivetrain, and sometimes multiple keepers in a short period, none of which the odometer alone will tell you. If the mileage looks low for the van's age and stated history, it's worth extra scrutiny — see our guide to spotting a tampered odometer for what to look for.
Buying checklist — beyond the history check
- Load area condition. Check the floor, ply-lining (if fitted) and rear doors for damage consistent with regular heavy use.
- Rust and underbody. Vans work harder and cover more miles than the average private car — check the sills, wheel arches and underbody for corrosion, especially on anything that's spent time doing local delivery work.
- Tyre wear pattern. Uneven wear across the rear axle can point to persistent overloading — worth checking against the payload figure above.
- Service history. A stamped or digital service record from a reputable garage; be cautious of a van with no record at all given the mileage it's likely covered.
- Door seals and locks. Rear and side-loading door seals take a beating on a working van — check for perishing or gaps that let water in.
FAQs
What should I check before buying a used van?
Its payload against what you need to carry, which MOT class it falls into, a history check for finance/write-off/theft/mileage, and the load area and underbody for wear consistent with hard use.
What's the difference between a Class 4 and Class 7 MOT?
Class 4 covers vans up to 3,000kg design gross weight; Class 7 covers heavier vans between 3,000kg and 3,500kg, and needs a garage with heavier-duty testing equipment.
How do I find a van's payload capacity?
Check the weight plate (usually inside the driver's door or under the bonnet) for the gross vehicle weight, then subtract the van's own unladen weight — don't rely on a brochure figure for a base-spec model if this one has extras fitted.
Do I need a history check on a used van?
Yes — the same finance, write-off, theft and mileage risks apply to vans as cars, and are checked the same way, from the registration number.
Are ex-courier or ex-rental vans worth avoiding?
Not automatically, but they've usually covered more miles and seen harder use than a private van of the same age — check the service history and load area condition carefully rather than ruling them out on reputation alone.
Does a car history check work for a van registration?
Our check runs from the registration number for UK-registered vehicles. If you're unsure a specific check covers your van, contact us before you rely on the result.
