Ask any UK car buyer whether they need to pay for a vehicle history check and you will get a heated answer either way. One camp swears the free GOV.UK tools are all you will ever need. The other insists you would be mad to buy without an HPI check. The truth sits in between, and it comes down to knowing exactly what each source can and cannot see.

Free government data is genuinely excellent for what it covers, and you should always run it first. But there are three things it simply does not hold, and each of them can cost you the entire value of the car. This article lays the two side by side so you can decide, for the specific car in front of you, whether to reach for your wallet.

What the free GOV.UK checks show

GOV.UK offers several free tools, and together they are more powerful than most buyers realise. Punch in the registration number and you can pull up:

Check MOT history (gov.uk/check-mot-history). The full MOT record going back to 2005: pass and fail results, advisories, and crucially the recorded mileage at every single test. This is the best free defence against clocking that exists anywhere.
Check MOT status. Whether the car currently holds a valid MOT.
Check vehicle tax. Whether it is taxed or declared SORN.
DVLA vehicle enquiry. Make, model, colour, engine size, fuel type and year of manufacture, straight from the DVLA record.

Used properly, these tools let you verify that the advert is honest, spot a wound-back odometer and confirm the car is road-legal, all for free. For a cheap, low-risk runaround from a trusted seller, this may be all you strictly need. Our guide to checking a used car in the UK walks through how to use them in order.

What the free checks do NOT show

Here is the catch, and it is a big one. GOV.UK data will not tell you:

Outstanding finance. If the previous keeper bought the car on finance and has not cleared it, the finance company still legally owns it. They can repossess it from you even though you paid in good faith.
Write-off category. Whether the car has been declared a total loss by an insurer, and if so whether it is Category A, B, S or N.
Stolen markers. Whether the car is recorded as stolen on the Police National Computer.
Keeper count, plate changes and colour changes. Useful signals of a car’s past that GOV.UK does not surface.

Notice that all three of the biggest financial disasters, finance, write-off and theft, sit in the blind spot. That is precisely the gap a paid check fills.

What a paid HPI check adds

“HPI check” has become a generic term, a bit like calling a vacuum cleaner a Hoover. Several providers offer essentially the same thing, drawing on the same insurance and finance industry data (the Experian/HPI databases). The main options include HPI itself (around £19.99), the AA (around £14.99), RAC Passport, CarVeto and Motorcheck. Prices vary, and most run bundles if you are checking several cars.

For your money, a paid report typically reveals:

Outstanding finance registered against the car.
Write-off category and the date it was recorded.
Stolen status via the Police National Computer.
Mileage discrepancies flagged across data sources.
Plate and colour change history.
Number of previous keepers.

Many providers also include a guarantee that pays out if their data proves wrong and you suffer a loss, which is worth reading the small print on. The cover levels and exclusions vary widely between providers, so if the guarantee is a big part of why you are paying, read what it actually promises rather than the headline figure.

It is worth understanding why these providers can see things GOV.UK cannot. The finance and insurance industries feed their records into shared databases, and the paid checks query those. When a lender registers a hire purchase agreement, or an insurer writes a car off, that event lands in the same pool. GOV.UK, by contrast, only holds the data the government itself generates: MOT tests, tax, and the DVLA registration record. Neither source is “better”; they simply hold different things, which is exactly why the sensible approach is to use both rather than pick a side.

Write-off categories: what the letters mean

If a paid check returns a write-off marker, do not panic, but do understand the category. Since the system was updated in October 2017, UK insurers use four:

Category A. Scrap only. The whole car must be crushed. Never to be bought.
Category B. The body shell must be crushed, though salvageable parts may be reused. Not a car you drive.
Category S (structural, formerly Cat C). Suffered structural damage but is repairable. Must be re-registered with DVLA after repair.
Category N (non-structural, formerly Cat D). Damage was cosmetic or non-structural. No re-registration required.

Cat S and Cat N cars are perfectly legal to buy and can represent good value if the seller declares the status, the price reflects it, and you accept the knock-on effects on insurance premiums and future resale. As a rough rule of thumb, a repaired Cat S or N car sells for meaningfully less than an equivalent car with a clean history, and it will be harder to sell on for the same reason. That discount can make it a smart buy if you plan to keep the car for years, or a trap if you expect to move it on quickly. The problem comes when a write-off is quietly hidden, which is exactly why the paid check earns its fee: a seller who does not mention a Cat S marker is either careless or dishonest, and neither is a good sign.

So do you actually need to pay?

Here is the honest recommendation. Run the free GOV.UK checks on every car, without exception. Then pay for a history check when any of the following apply:

The car is worth more than a few hundred pounds (which is almost always).
You are buying privately rather than from a franchised dealer.
Anything in the advert, the paperwork or the seller’s story feels slightly off.
The car might be an import, where UK records may be thin.

For most buyers on most cars, the £15 to £20 is trivial insurance against a four-figure loss. Skipping it to save the price of a takeaway is a false economy.

One report, one checklist, one price with MotoPPI

Juggling GOV.UK tabs, a paid report and a physical inspection is fiddly, and it is easy to miss something. MotoPPI brings it together: it checks a car’s history across more than 20 databases, then pairs that with a model-specific inspection checklist and a repair-cost estimate so you know what you are really buying and what to argue over on price. The first check is free.

Download MotoPPI on the App Store and run your first history check for free.

Frequently asked questions

Is an HPI check the same as a GOV.UK check?

No. GOV.UK checks are free and cover MOT history, tax and the DVLA record. An HPI-style check is paid and adds outstanding finance, write-off category, stolen markers and keeper history, none of which GOV.UK holds.

How much does a paid vehicle history check cost?

Typically around £15 to £20 for a single car. HPI is roughly £19.99, the AA around £14.99, with RAC Passport, CarVeto and Motorcheck as alternatives. Multi-check bundles bring the per-car price down.

Can GOV.UK tell me if a car has outstanding finance?

No. Outstanding finance is one of the key gaps in the free data. You need a paid check to see it, and it is one of the most important things to confirm before you buy.

What is the difference between Category S and Category N?

Category S means the car suffered structural (repairable) damage and must be re-registered with DVLA after repair. Category N means non-structural, usually cosmetic, damage with no re-registration needed. Both are legal to buy once properly repaired.
