# When to Run a Car History Check and Why the Timing Matters

Published 27 September 2026. CarCheckUp guide: https://carcheckup.co.uk/blog/when-to-run-a-car-history-check-and-why-the-timing-matters/

> A car history check is only as good as the day it was run. Here is when to check a car, why an old check or the seller's check isn't enough, and what to check twice.

A car history check shows what the records held *on the day it was run*. Records change all the time, so when you run your check matters almost as much as running one at all.

## Why records change

- **Finance** can be taken out against a car at any time, including just before it's sold.
- **Theft** is recorded when it's reported, which can be days after the car was taken.
- **Write-offs** are added when an insurer settles a claim, which can take weeks after an accident.
- **MOTs and mileage** are added after every test.

A check from last month can miss something that's on the record today.

## The best times to check

1. **Before you travel to see the car:** a [free check](https://carcheckup.co.uk/) shows the MOT history, recorded mileage, tax status and vehicle details, and whether they match the advert. It can save you a wasted journey.
2. **When you've decided to buy:** run the [full history check](https://carcheckup.co.uk/sample-car-history-report/) for finance, write-off, theft, keepers and plate changes.
3. **On the day you pay,** if some time has passed since your check, especially for finance and theft.

## Why the seller's check isn't enough

Sellers sometimes show a clean history check to reassure buyers. Treat it as a starting point, not proof:

- it may be weeks or months old;
- it may be for a different car, or a screenshot that has been edited;
- you can't be sure what it covered.

Run your own check on the registration, and compare the VIN on the car with the report and the V5C. See [where to find the VIN](https://carcheckup.co.uk/blog/where-to-find-the-vin-on-a-car-and-check-it-matches-the-v5c/).

## Save money if you're viewing several cars

If you're comparing a few cars, a multi-check bundle costs less per report, and unused checks don't expire. See our [prices](https://carcheckup.co.uk/prices).

## Key points

- A check shows the records on the day it's run; records change all the time.
- Check before viewing, before deciding, and again on the day you pay if time has passed.
- Run your own check rather than relying on the seller's. Read [what a car history check covers](https://carcheckup.co.uk/blog/what-is-a-car-history-check/).

You can start with a **free car check** the moment you find an advert: enter the registration on our [car check](https://carcheckup.co.uk/) page to **view the car's history** from DVLA and MOT records, then run the full **car history check** for finance, write-off and stolen records just before you pay.
