How old does a car have to be to be MOT exempt?

So how old does a car have to be to be MOT exempt? Generally, passenger vehicles and vans over 40 years old are exempt from annual MOT testing.

In the UK, vehicles over 40 years old are usually exempt from annual Ministry of Transport (MOT) testing and road tax. This applies as long as they have not been substantially changed.

If you need to check an MOT for a vehicle, you can use our handy tool, which provides all the information you need.

However, you must hold the proper tax exemption documents. These show that your car is a historic or classic vehicle and does not need an MOT.

Otherwise, driving it can lead to fines of up to £2,500 and three penalty points for using a vehicle in a dangerous condition.

Missing the right MOT and road tax paperwork can also cut your older car’s resale value and make it a tough sell later.

How old does a car have to be to be MOT exempt? The 40-year rule

So, how old does a car have to be to be MOT exempt? In short, it must have been built or first registered more than 40 years ago.

Under gov.uk’s 40-year rule for historic vehicles, set by the Department for Transport, a non-commercial vehicle does not need an MOT if it was first registered more than 40 years ago, with no ‘substantial changes’ in the past 30 years.

This exemption operates on a rolling basis. According to gov.uk, it applies to cars built or first registered more than 40 years ago. The exemption holds as long as nobody has replaced the chassis, body, axles, or engine to change how the car works.

So, if your car was built before 1 January 1986, gov.uk and the DVLA confirm you can stop paying vehicle tax from 1 April 2026. If you do not know the build date but it was registered before 8 January 1986, the same date applies.

However, you must register your older car or van under the Historic Vehicle taxation class with the DVLA. Putting your vehicle into the ‘historic tax class’ grants you a vehicle tax exemption because of its age.

Without regular MOT testing, vehicle issues may go unnoticed, raising the risk of accidents or breakdowns. Owners of MOT exempt vehicles must keep their cars roadworthy through regular maintenance and checks.

It is also illegal to drive in the UK without car insurance. This is true even if your vehicle is MOT exempt. Specialist policies for classic or vintage cars may offer extra benefits or cover.

Determining substantial changes

Older vehicles that have made ‘substantial changes’ may not qualify for MOT exemption, even if they have been registered for over 40 years. According to gov.uk’s exemption criteria, published by the Department for Transport, a ‘substantial change’ means altering one of the car’s main components in a way that changes how it works.

The criteria only assess three areas: the chassis or bodyshell, the axles and running gear, and the engine. Changes made to preserve your car, or to improve its safety, efficiency, or environmental performance, are generally accepted, as long as they do not change how the car fundamentally works. Examples that do not remove your exemption include:

✅ Axles and running gear: upgrades to brake components such as pads, discs, or lines, or suspension changes that improve safety or performance without altering the original type or method.

✅ Engine: fitting an alternative engine of a similar type, for example to improve efficiency or lower emissions.

✅ Chassis or bodyshell: repairs or replacements of the same specification made to keep your car on the road.

Cosmetic and interior updates, such as new upholstery or a modern stereo, fall outside these three areas, so they do not affect your exemption.

According to gov.uk, you can book an MOT for your car up to one month (minus a day) before the expiry date on your current MOT certificate. Tests must be performed at certified MOT assessment centres.

Booking in advance helps you secure a convenient appointment and keeps your vehicle compliant. Booking is straightforward too. Find an approved MOT test centre near you and book using your reg.

The MOT test usually takes 45 minutes to an hour, although timing varies.

MOT exemption declaration process

Before declaring your vehicle as MOT exempt, we recommend consulting professional mechanics for a full-body car inspection. This inspection will confirm whether it meets the DVLA’s criteria for exemption. Review your documentation too, including registration details and any previous MOT certificates.

If your vehicle meets all MOT exemption guidelines, notify the DVLA of your vehicle’s MOT exemption status. This typically involves filling out a declaration form and submitting it to the DVLA.

Then, update your vehicle’s taxation class to reflect its exempt status as a historic or classic vehicle. This is a legal requirement to continue driving on UK roads.

Keep all DVLA correspondence and documentation about your exemption status for future reference.

Additional considerations: 

While consultation is recommended to ensure compliance and eligibility, there may be exceptions or specific circumstances where extra advice is needed.

Consider seeking specialist advice if your vehicle has undergone extensive modifications or restoration work. Speaking to historic vehicle clubs or associations may also help if your vehicle belongs to a particular make or model.

Financial benefits of MOT and road tax exemption

Qualifying for MOT and road tax exemptions as an older vehicle can lead to real savings for both car owners and people looking to sell. Highlights include:

• Tax and testing costs: exemption from the annual MOT test and vehicle tax saves historic vehicle owners money and can reduce ownership costs.
• Insurance premiums: all UK vehicles need insurance, but premiums for older cars are often lower, thanks to their lower resale values.
• Maintenance and repairs: older cars may need more maintenance, but overall costs can beat financing and servicing a newer car, especially with DIY repairs.
• Value over time: older vehicles are past the initial period of steep depreciation, so they may hold a more stable value over time.
• Resale price: if you are buying a used car, an older vehicle can save you money, as high mileage and wear lower its value.

Should you still get a voluntary MOT?

You do not have to test an exempt car, but you can still book a voluntary MOT to confirm it is roadworthy. According to gov.uk, an MOT exempt owner must still keep the car roadworthy. A yearly check is a simple way to prove you are meeting that duty.

A voluntary test also catches faults early, from worn brakes to tyre or suspension issues, before they become expensive or dangerous. Keeping a recent MOT record can reassure your insurer and any future buyer that a classic has been looked after.

You can check an MOT for any vehicle with our free tool. Skipping the test is legal, but driving a dangerous vehicle is not, and it can cost up to £2,500 and three penalty points.

FAQs

Are vehicles over 25 years old tax exempt in the UK?

No. In the UK there is no 25-year exemption. According to gov.uk and the DVLA, both MOT and vehicle tax exemptions follow the rolling 40-year rule.

For tax specifically, your car must have been built before 1 January 1986 to be exempt from 1 April 2026.

Specialist classic-car policies are widely available and can suit how these vehicles are used. See our guide to whether your car insurance covers you.
