MOT Test Changes 2026: What Is New
Car Owl
Published in English •
Summary
- Emissions testing is getting stricter: Diesel and petrol cars face tighter limits as the UK pushes for cleaner air.
- Electric car MOTs are being reviewed: The Government is considering how EVs should be tested differently.
- Tyre age may become a factor: There is growing pressure to fail tyres older than 10 years regardless of tread depth.
The MOT test evolves regularly. Changes reflect new technology, safety research, and environmental targets. Staying informed helps you prepare your car and avoid unexpected failures.
Here is what we know about MOT changes coming in 2025 and 2026.
Recent Changes
Several updates have already taken effect:
- DPF check (2014): A missing or modified Diesel Particulate Filter is an automatic failure.
- Defect categories (2018): Faults are now classified as Dangerous, Major, or Minor instead of just pass or fail.
- Diesel emissions (2022): Stricter smoke limits for diesel vehicles, especially older models.
- ULEZ-aligned checks: Some emissions-related checks now align more closely with clean air zone standards.
Proposed Changes for 2026
The Department for Transport and DVSA are consulting on several potential changes:
| Proposed Change | Status | Impact |
|---|---|---|
| Tighter petrol emissions limits | Under consultation | Older petrol cars may struggle to pass |
| EV-specific test items | Under review | Battery health and high-voltage safety checks |
| Tyre age limit | Under discussion | Tyres over 10 years old may fail regardless of tread |
| ADAS checks | Early consultation | Cameras and sensors for driver assistance systems may be tested |
| Noise testing | Proposed | Aftermarket exhausts may face decibel limits |
None of these changes are confirmed yet. The DVSA consults widely before implementing new test items. Check the Government website for the latest updates.
Electric Car MOTs
Electric cars currently undergo the standard MOT with some items removed (no exhaust emissions test, no fuel system check). The Government is reviewing whether to add:
- Battery health check: Measuring the capacity of the high-voltage battery.
- High-voltage system inspection: Checking cables and connectors for damage.
- Regenerative braking check: Ensuring the system works correctly.
These changes would not apply until at least 2026 or later. The test infrastructure needs significant investment first.
What This Means for You
Practical steps you can take now:
- Check your tyres: Look at the date code on the sidewall. Tyres older than 10 years should be replaced.
- Maintain your emissions system: Keep the DPF, catalytic converter, and exhaust in good condition.
- Service your car regularly: A well-maintained car passes the MOT more easily, regardless of changes.
- Stay informed: Follow DVSA announcements for confirmed changes.
How to Prepare for Your MOT
Regardless of future changes, the current MOT covers over 150 check points. Prepare by:
- Checking all lights, including indicators and brake lights.
- Topping up screen wash.
- Checking tyre tread depth (minimum 1.6 mm across the central three-quarters).
- Making sure the horn works.
- Checking the windscreen for chips larger than 10 mm in the driver's view.

History of MOT Changes
The MOT test has evolved significantly over the decades:
| Year | Change |
|---|---|
| 1960 | MOT test introduced for cars over 10 years old |
| 1967 | Age reduced to 3 years |
| 1991 | Emissions testing added |
| 2012 | MOT results available online |
| 2014 | DPF check introduced |
| 2018 | Defect categories (Dangerous, Major, Minor) introduced |
Each change has made the test more thorough and the roads safer. The upcoming changes continue this trend.
What About Classic Cars?
Cars over 40 years old are currently exempt from the MOT. However:
- They must still be roadworthy. The driver is legally responsible.
- Many classic car owners still choose to MOT their vehicles voluntarily.
- There has been discussion about tightening the exemption rules, especially for cars that have been substantially modified.
If you own a classic, a voluntary MOT is good practice. It proves the car is safe and can help with insurance.
MOT Testing Stations
The DVSA is also reviewing the standards required of testing stations themselves:
- Equipment upgrades: Stations may need newer emissions testing equipment to meet tighter standards.
- Tester training: New test items will require additional training for MOT testers.
- Digital reporting: More detailed digital records of each test are expected, improving transparency for car owners.
- Quality audits: Increased random inspections of testing stations to ensure consistent standards.
These improvements benefit drivers by ensuring fairer and more consistent testing across the UK.
Final Thoughts
MOT changes reflect evolving technology and safety standards. The 2026 updates are likely to focus on emissions, tyre age, and preparing for the electric car era.
The best preparation is keeping your car well maintained. A car that is serviced regularly and looked after properly will pass any version of the MOT.
