MOT Check vs HPI Check: What's the Difference?
Quick Answer
An MOT check shows test history, advisories and recorded mileage, free via DVSA and sites like MOT Checkup. An HPI check shows finance, theft, write-off and ownership records and typically costs £19.99. Used car buyers in the UK need both: MOT for mechanical history, HPI for legal and financial status.
Online forums are full of buyers who ran one check, missed a major issue, and paid the price. A free MOT history check is essential, but it is only half the picture for any used car under £20,000.
What an MOT check actually shows
An MOT history check uses the DVSA's public database to return every annual test on a UK-registered vehicle since 2005. It shows pass and fail dates, recorded mileage at each test, advisories, minor and major defects, and the test station postcode where each test took place.
Sites like MOT Checkup combine this raw data with AI-generated insights to flag mileage anomalies, advisory patterns and likely upcoming repair needs. The underlying data is always free because it comes from a public DVSA API.
What an HPI check actually shows
An HPI check (sometimes called a vehicle history check or provenance check) is a paid service that aggregates private databases not available via DVSA. It covers outstanding finance, insurance write-off categories (Cat A/B/S/N), stolen vehicle records from the Police National Computer, and number plate change history.
Major HPI providers include hpi.co.uk, AA Cars, RAC, MyVehicle and AutoCheck. Standard checks cost £19.99-29.99 with multi-check bundles around £35-50.

Why buyers need both
An MOT check tells you what is mechanically wrong (or has been). An HPI check tells you whether you can legally buy the car at all. A vehicle with outstanding finance can be repossessed by the lender even after you pay the seller in full - the finance company has prior claim under the Hire Purchase Act 1964.
Around 1 in 4 used cars in the UK has a finance, write-off or mileage discrepancy hidden in its history (HPI/Cap HPI annual data). Spending £20 on an HPI check before a £10,000 car purchase is straightforward risk management.
Free alternatives for HPI-style data
MOT Checkup offers a free stolen check and free finance check using public and partner data, covering the most common HPI use cases. While these do not replicate every HPI field, they catch the highest-risk items at zero cost.
For full provenance with insurance company write-off categories, a paid HPI is still the most thorough option. Combining a free MOT history check with a paid HPI is the gold standard for serious used car purchases.
When MOT history alone is enough
If you are buying a car under £2,000 cash from a private seller you trust, an MOT history check may be enough due diligence. Outstanding finance is rare on cheap cars because finance companies do not typically lend below £4,000-5,000.
For any private purchase above £3,000, or any dealer purchase regardless of price, run both checks. Dealers should be willing to share their own HPI report - if they refuse, walk away.
How to combine both checks
Start with a free MOT history check to see if the seller's claims about mileage and faults match the public record. Look for: mileage that decreases between tests (clocking), gaps where MOTs were skipped, and recurring advisories never addressed.
If MOT history checks out, run a paid HPI for the legal-status side. Cross-reference both with the V5C log book. If anything fails to match, walk away or negotiate hard. See our free vehicle check guide for a step-by-step process.
Frequently Asked Questions
Is a free MOT check as good as an HPI check?
No. They cover different things. An MOT check shows mechanical history, an HPI check shows legal and financial status. Most used car buyers need both before purchase.
Is HPI check worth £19.99?
Yes for any used car over £3,000. The cost is small compared to the risk of buying a car with outstanding finance, an undisclosed write-off, or stolen status. Around 1 in 4 used cars has an issue.
Where can I run a free MOT history check?
GOV.UK provides the official DVSA service, and sites like MOT Checkup add advisory pattern analysis and AI insights. Both pull from the same public DVSA database.
Can MOT Checkup replace an HPI check?
MOT Checkup offers free stolen and finance checks that cover the most common HPI use cases. For full insurance write-off category data, a paid HPI is still more thorough.
What does an HPI check cover that an MOT check does not?
Outstanding finance, insurance write-off categories (Cat A/B/S/N), stolen vehicle records, number plate transfers, and ownership history. None of these appear in DVSA MOT data.
Free MOT history covers mechanical past; paid HPI covers legal status. Start with a free MOT history check before any used car deal.
