Cars over 40 years old can usually be taxed for free and don't need an MOT. How the historic vehicle rules work, and what to check when buying a classic.
Once a car reaches 40 years old, it can usually be taxed for free and no longer needs an annual MOT. The rules roll forward every year, so each year a new set of cars becomes eligible.
Free road tax: the historic vehicle tax class
Cars built before 1 January 40 years ago can be taxed in the historic vehicle class from 1 April each year. So from 1 April 2026, cars built before 1 January 1986 are eligible; from 1 April 2027, cars built before 1 January 1987.
- The car must still be taxed every year. It's just free.
- The keeper applies to move it into the historic class, usually at a Post Office that deals with vehicle tax, with the logbook (V5C).
- Cars used for commercial purposes, such as a business, don't qualify.
MOT exemption
Cars built or first registered more than 40 years ago don't need an MOT, unless they've been substantially changed, for example with a different engine, chassis or suspension that changes how the car works. The keeper confirms the car is exempt when they tax it.
The car must still be kept roadworthy, and you can be fined for driving one that isn't. Many owners still have a voluntary MOT each year as an independent safety check.
London ULEZ
Cars in the historic vehicle tax class are exempt from London's Ultra Low Emission Zone charge. That can make a big difference if you live or drive in London, as most older cars don't meet the ULEZ standard otherwise. See London ULEZ explained.
Buying a classic: what to check
- The history. Older cars may not have a full MOT history if they've been exempt or off the road. Ask for old MOT certificates, bills and restoration records. A history check still shows finance, theft and write-off records.
- Originality. Matching numbers (the engine and chassis numbers the car left the factory with) matter for value. Check them against the logbook.
- Rust. Corrosion is the biggest enemy of classic cars. Check sills, floors, wheel arches and around the windscreen.
- Insurance. Specialist classic car insurance, often with a limited annual mileage, can be much cheaper than a standard policy.
- An inspection. A specialist in the model can spot problems an ordinary mechanic might miss.
