What is the cheapest way to check a used car in the UK?

The cheapest way to check a used car in the UK is to start with MOT Checkup's free MOT history check, layer on the free DVLA tax, identity and log book data plus the free stolen-log-book checks, and only pay for a full HPI-style report when the purchase price makes outstanding finance or write-off history a real risk. The free layer alone catches most rough cars.

TL;DR

Free first, paid only if needed. Order of operations: MOT history → tax/SORN status → free stolen and cloning checks → known faults for that model → paid HPI-style report for cars over a few thousand pounds. Start with the free MOT check here.

What MOT Checkup checks for free

The cheapest way to check a used car starts at £0: MOT Checkup's free report covers the official MOT, mileage, tax, recall and DVLA log book record in one lookup, so you only pay for licensed data once a car survives it.

Every MOT test since 2005 — date and pass/fail result for each, from the official DVSA record. The advisories, failure defects and odometer reading behind each test are free in full on cars with up to five MOT tests, and for the earlier tests on longer histories.
Mileage-drop warning — the report flags any fall in recorded mileage between MOT tests, the classic sign of a wound-back odometer.
AI reliability analysis — a score out of 100 with plain-English strengths and concerns, worked out from that car’s own MOT record.
Tax and MOT status — current DVLA tax status and MOT expiry date.
Safety recalls — DVSA manufacturer recalls issued for the make and model (whether the fix was done on this car is a question for a franchised dealer).
Date the V5C log book was last issued — straight from DVLA. We show this date, not the number of previous keepers.
Export marker — whether DVLA has the car marked for export.
Identity cross-check: DVLA vs MOT record — whether make, colour, fuel type and engine size agree across both official records. A mismatch can point to a cloned plate or an undeclared respray.
Recent V5C reissue flag — a log book reissued shortly before a sale is worth a question.
Long MOT-history gaps — years with no test, which usually mean the car was off the road or in for a long repair.
Import signal — first UK registration much later than the year of manufacture.

Free tip: compare the issue date on the seller’s V5C log book with the date DVLA holds for the last V5C issued — a mismatch means the document in front of you isn’t the current one.

Not held, at any tier: outstanding finance, insurance write-off records (MIAFTR), police stolen markers (PNC) and the number of previous keepers. For those, use a provider that licenses the registers — see our honest price comparison. Paid tiers here (Basic £2.99, Premium £3.99, two-report bundle £5.99) add the newest tests’ full detail, a branded PDF and an AI vehicle Q&A chat over the same official data.

Run a free MOT check now:

Step 1 — MOT history (free)

The single highest-value free check. Enter the reg into our free MOT check and you'll see the full DVSA test history: pass/fail, mileage at every test, dangerous defects, and advisories. Three things to look for:

Mileage continuity. A clocked car gives itself away here. Mileage going backwards or implausible jumps are unmistakable.
Recurring failures. Same component failing year after year suggests a deferred-maintenance approach.
Dangerous defects. Even one is a big flag — was it actually fixed?

Step 2 — Tax, SORN and basic DVLA data (free)

The DVLA exposes current tax status, SORN status, basic vehicle details (colour, fuel, engine size, year of manufacture, CO2 band) for free. Use our tax check or the joined MOT and tax check. Watch for:

Colour mismatches between DVLA record and what you're seeing.
Long SORN periods that don't match the seller's story.
Engine size or fuel mismatches — sometimes a sign of cloned plates.

Step 3 — Stolen and cloned-car checks (free)

No free source returns a police stolen marker — that sits on the Police National Computer, which is closed to the public, and MOT Checkup does not hold it at any tier. What is free: checking the V5C serial number against GOV.UK's published ranges of stolen blank log books, matching the VIN on the car to the V5C, and comparing the DVLA record (make, colour, engine, export marker, date the V5C was last issued) with the car and the paperwork. Our stolen car guide walks through each one, and a paid PNC-linked check covers the rest. For a deep stolen-history dive, see our blog post how to check if a car is stolen.

Step 4 — Model-specific weak points (free)

Before agreeing a price, check our common faults pages for the model. Knowing that a particular generation is prone to, say, DPF failures or rear subframe corrosion lets you ask the right test-drive questions and price the risk in.

Step 5 — Paid HPI-style report (only if it's worth it)

Pay for a full history report when:

The car costs more than a few thousand pounds, where outstanding finance or undisclosed write-off categories could swallow your entire purchase.
You're buying privately, where there's no dealer to chase if something is wrong.
The MOT history has gaps you can't explain — finance and insurance write-off data may fill the picture.

We compare paid checks honestly in MOT vs HPI check and is an HPI check worth it.

The order matters

Most rough used cars get filtered out at step 1. Run the free MOT check before you waste a Saturday on a viewing. If a car's history reads badly, you've saved yourself the petrol — and haven't spent a penny.

Frequently asked questions

What's actually free?

MOT history (DVSA), current tax and SORN status (DVLA), basic vehicle details such as colour, fuel and engine size (DVLA), the export marker and the date the V5C log book was last issued (DVLA), and DVSA safety recalls for the model. All of these can be obtained without payment from a registration number alone. A police stolen marker is not free anywhere — the Police National Computer is closed to the public — but GOV.UK's list of stolen blank V5C serial numbers is, and you can check the log book in front of you against it.

What does MOT Checkup check for free?

MOT Checkup's free report shows every MOT test on record since 2005 with its date and result, flags any drop in recorded mileage between tests (the classic sign of a wound-back odometer), gives an AI reliability score out of 100 with plain-English strengths and concerns, and returns the car's DVLA tax status, MOT expiry, export marker and the date its V5C log book was last issued, plus any DVSA safety recalls for the make and model. It also runs free identity cross-checks: whether DVLA and the DVSA MOT record agree on the car's make, colour, fuel type and engine size (a mismatch can point to a cloned plate or an undeclared respray), whether the V5C was reissued recently, long gaps in the MOT history that suggest time off the road or a long repair, and whether the car was first registered in the UK long after it was built (a sign of an import). Free tip: compare the issue date on the seller's V5C log book with the date DVLA holds for the last V5C issued — a mismatch means the document in front of you isn't the current one. MOT Checkup does not hold outstanding finance, insurance write-off (MIAFTR), police stolen (PNC) or number-of-previous-keepers data at any tier — for those you need a licensed provider.

What's worth paying for?

Outstanding finance, insurance write-off categories (Cat A/B/S/N), full keeper history, plate transfer history, and salvage data. These come from licensed sources — finance houses, insurance bureaux, salvage networks — and can't legally be redistributed for free.

How much should a paid check cost?

A single-vehicle full HPI-style report typically sits between GBP 5 and GBP 20 depending on provider and bundle. Multi-pack credits bring the per-check price down. Anything significantly above GBP 20 for one report is overpriced unless it's bundled with a guarantee or insurance product.

Should I trust a dealer's HPI check?

Reputable dealers do run history checks and will share the result on request. But the report is only as recent as the day it was run — finance can be added between the dealer's check and your purchase. Running your own check on the day you buy is cheap insurance.

Is there a free HPI alternative?

Genuine outstanding-finance and write-off data are not free anywhere — the data licences cost real money. If you're seeing a 'free HPI check' offered online, it's almost always a marketing funnel that takes your details and then upsells the actual report. Free MOT history, yes; free finance check, no.

Should I buy a used car that has no MOT?

Only with eyes open. A car sold without a current MOT is legally untestable on the road — the seller cannot drive it home for you, and you cannot tax or insure it normally. The price should reflect at least the £54.85 test fee plus likely repair cost. Use the MOT history to estimate what work is due, and budget for surprise failures. Walk away if the seller is hiding why it has no MOT.

How do I check for Cat S or Cat N write-off cheaply?

Write-off categorisation (Cat A, B, S, N) is held by the Motor Insurance Anti-Fraud and Theft Register (MIAFTR), a paid data source. There's no free way to access it directly. The cheapest approach is one of the bundled paid checks (£5–£20 — see /vs/motcheckup-vs-hpi for which providers include MIAFTR data). Free MOT history alone won't tell you if a car was written off.

ANPR cameras read the DVSA MOT database automatically — nobody has to pull you over first.
