The Classic Car Owner's Guide
The law, insurance and security
By Jon Cosson · Last checked
Classic cars have some rules of their own, and a lot of half-remembered advice around them. This section sets out what the law actually says, how classic insurance differs from ordinary cover, and how to protect a car whose value makes it a target. The security pages are written by a retired chief information security officer, because the threats to classic owners now include fraud as well as theft.
The essentials
- MOT exemption. Cars built or first registered more than 40 years ago are exempt from the annual MOT, as long as they have not been substantially changed in the last 30 years. The exemption is rolling: a car qualifies once it passes 40 years old, and you do not have to apply. An exempt car must still be roadworthy, and owners can choose to have a voluntary MOT.
- Historic vehicle tax. Cars built before 1 January 1986 can be taxed in the historic class, which costs nothing, from 1 April 2026. If the build date is not known, a car first registered before 8 January 1986 qualifies. The cut-off date moves forward a year every 1 April. You still have to tax the car, or declare it off the road.
- The V5C log book. Keep it accurate, in your name and at your address. Never share photographs of it or its document reference number, which can be misused to obtain a fraudulent copy.
- Classic insurance. Specialist policies are often written on an agreed value, which needs a valuation and photographs, and usually come with a mileage limit and conditions about where the car is kept.
- Theft. Classic cars are easy to steal and their parts are valuable. Physical deterrents, a hidden battery isolator, a tracker and a photographic record of the car's identifying marks all help.
- Fraud. Cloned registrations, fake adverts and payment scams now cause classic owners as much trouble as thieves.

FAQs
- Do classic cars need an MOT?
- Cars built or first registered more than 40 years ago are exempt, provided they have not been substantially changed in the last 30 years. They must still be roadworthy, and a voluntary MOT is a sensible check.
- Do classic cars pay road tax?
- Cars built before 1 January 1986 can be taxed in the historic vehicle class, which is free. They still have to be taxed, or declared off the road with a SORN.
- What is an agreed value policy?
- A policy where you and the insurer agree the car's value when the cover starts, usually backed by a valuation and photographs. If the car is written off, or stolen and not recovered, that agreed figure is paid, less any excess, rather than a market value worked out after the loss.
