Why a Write‑Off Checker Matters
When buying a used car in the UK, knowing whether the vehicle has been written‑off by an insurer can save you from costly repairs and legal trouble. A write‑off checker pulls data from the Motor Insurance Anti‑Fraud and Theft Register (MIAFTR), the DVLA MOT database, and other sources to reveal the true history of the car.
What Makes a Write‑Off Checker “Best”?
The best checker combines comprehensive data, up‑to‑date records, and a clear, user‑friendly report. Look for these features:
- Full MIAFTR coverage – includes Category A, B, S and N write‑offs.
- DVLA MOT history – shows past failures and mileage readings.
- PNC stolen‑vehicle marker – alerts you if the car has been reported stolen.
- Finance check – reveals any outstanding hire‑purchase or PCP agreements.
- Clocking detection – highlights mileage discrepancies.
- Previous keepers list – gives you a sense of how many owners the car has had.

4. Review the report and decide whether the car meets your standards.
Understanding Write‑Off Categories
The MIAFTR defines four main categories:
- Category A – The vehicle is a total loss and must be crushed; no parts can be reused.
- Category B – The vehicle is a total loss but can be used for parts; the chassis is destroyed.
- Category S (formerly Category C) – Structurally repairable; the car can return to the road after proper repairs.
- Category N (formerly Category D) – Non‑structural damage only; the car is road‑worthy after minor work.
Knowing the category helps you estimate repair costs and future insurance premiums. For example, a Category S car may be safe to drive but could attract higher premiums, while a Category N vehicle usually has a lower impact on insurance.
Other Write‑Off Checkers on the Market
There are several alternatives, but they often lack one or more of the essential data points. Below is a quick comparison:
- CheckMOT.co.uk – Good MOT data, but no MIAFTR or finance check.
- HPI Check – Comprehensive finance and stolen‑vehicle data, but the write‑off information can be delayed.
- AutoCheck – Focuses on mileage clocking; missing detailed write‑off categories.
For a single, all‑in‑one solution, Motorpeek.com remains the most balanced choice for UK buyers.

Frequently asked questions
What is a write‑off category and why does it matter?
A write‑off category (A, B, S or N) describes how severely an insurer has damaged a vehicle. It tells you whether the car can be legally driven again and how insurance premiums or repair costs may be affected.
Can I rely solely on a write‑off checker to avoid hidden problems?
A write‑off checker gives you vital history, but it should be used alongside a full mechanical inspection and a review of service records to catch any issues not captured in the databases.
