Which check do you actually need?
Tell us about the vehicle and what is worrying you. We reply with the route that answers it (starting with the free official checks, because MOT history and tax status cost nothing) and, where you need finance, write-off or theft markers, the cheapest verified paid check that carries them.
The recommendation is built from the car check price index: 2 vendors with prices verified word for word against their own pages. We never sell you anything, and the figures we quote are the ones you can check yourself.
