Most guides to checking a used car's DVLA record stop at tax, MOT and colour. Fair enough: those are the fields that catch obvious problems. But the free DVLA vehicle enquiry service actually returns eighteen separate pieces of data, and several of the less obvious ones are genuinely useful if you know how to read them. This guide covers all of them, including the ones almost nobody explains: type approval, wheelplan, revenue weight, Euro standard and Real Driving Emissions (RDE).

We ran a real registration through the lookup to confirm this list is accurate rather than copied from a spec sheet. Every field below is one the service actually returned.

The basics

Registration number.The plate itself, normalised to DVLA's format.

Make.The manufacturer, as registered. Doesn't include model or trim; that detail comes from other sources, not DVLA.

Colour.DVLA's record of the car's colour at last update. A mismatch with what's in front of you means either a respray that wasn't declared, or one that was, in which case ask when and why.

Fuel type. Petrol, diesel, electric, hybrid and so on. Cross-check against the advert; a mismatch here is either a typo or a much bigger problem.

Dates and age

Date of first registration.The car's true age, independent of what the number plate implies. A "19-plate" first registered in late 2019 is still a 2019 car, but check the month against the advert's claimed age; sellers sometimes round in their favour.

Year of manufacture.Distinct from first registration, and worth checking separately. A car built in one year and registered the next (common with end-of-year stock) isn't a red flag on its own, but it's a detail worth knowing before you negotiate.

Date of last V5C issue.When the logbook was last reissued: new keeper, lost document, or changed details. A very recent date on a car the seller says they've owned for years deserves a direct question.

Tax and MOT

Tax status and due date.Whether the car is currently taxed, untaxed, or SORN, and when the current tax period ends. Remember tax doesn't transfer with the car; you'll need to tax it yourself the moment you take ownership, whatever the seller implies.

MOT status and expiry.Whether there's a valid MOT and when it runs out. No MOT usually means the car hasn't passed a test recently, which also has insurance implications if it's driven on the road.

Engine and emissions

Engine capacity (cc). The precise size, not a rounded marketing figure. Useful for confirming the advert matches the V5C, and relevant to your tax band and insurance group.

CO₂ emissions.Drives your VED band and any clean air zone charges. Worth checking before you commit to a car you'll be driving into a city centre regularly.

Euro standard. The emissions standard the car was type-approved to when new, from Euro 1 (early 1990s) through Euro 6 (current). This is what determines whether a diesel or older petrol car is exempt from Ultra Low Emission Zone charges. A pre-Euro 6 diesel bought without checking this field is a common and expensive mistake in London and other ULEZ cities.

Real Driving Emissions (RDE).A stricter real-world testing standard layered on top of Euro 6 for newer diesels (RDE1, then the tighter RDE2). Some ULEZ-adjacent schemes and future clean air rules treat RDE2 diesels more favourably than earlier Euro 6 cars that never faced the real-world test. If you're buying a diesel specifically for city driving, this field matters more than most buyers realise.

The fields almost nobody explains

Type approval category.A classification code (commonly M1 for standard passenger cars, N1 for light commercial vehicles, and others for specialist types) confirming what kind of vehicle the DVLA thinks this is. It matters most when it doesn't match what you're buying: a van registered as N1 but advertised and modified as a camper, for instance, can affect insurance, tax banding and what you're legally allowed to do with it.

Wheelplan.DVLA's description of the vehicle's axle configuration, almost always "2 axle rigid body" for an ordinary car. It's a field built for commercial vehicles and trailers more than hatchbacks, but a wheelplan that doesn't match a standard car body on something being sold as one is worth asking about.

Revenue weight.The maximum weight DVLA has on file for tax purposes. For an ordinary passenger car this is mostly a formality, but it becomes genuinely important if you're buying anything van-based or a car that's been converted, since it affects which licence category can legally drive it and which tax class applies.

Export marker

If this field is set, the car is flagged for export and should not be for sale on a UK driveway. Treat it as a stop, not a question.

Why the obscure fields are worth five extra minutes

None of type approval, wheelplan, revenue weight, Euro standard or RDE will make or break an ordinary hatchback purchase. But they matter a lot for three common situations: buying a diesel for regular city driving (Euro standard and RDE), buying anything van-derived or converted (type approval, wheelplan, revenue weight), and buying a car where something about the listing feels slightly off. In all three cases, the field that catches the problem is usually one of the ones the shorter guides skip.
