Changes to the MOT Test: Looking at a Few Recent Modifications

The MOT test has undergone several important changes and now feels a bit different. It is a necessary test because its primary aim is to verify that the vehicle complies with specific safety and environmental standards. At the same time, the DVSA is revising the legal foundation of the entire procedure, mainly because the car industry continues to advance and introduce new developments. Below is a quick view of the planned changes to the MOT framework for 2026.

Zero-Emission Commercial Vehicle Testing Procedure

The categorisation of zero-emission product vehicles between 3,501 and 4,250 kg is set to be the biggest development of 2026. From June 1, 2026, onwards, Class 7 MOT tests will become mandatory. Previously, electric vans heavier than 3.5 tonnes due to their battery packs were tightly controlled. As a result, they are grouped under the HGV class. That means, unlike petrol and diesel vans, the owners of these electric vans would need their MOT testing to start from the registration year. In practice, they should get an HGV MOT test, a tachograph test, and a driver-hour test too. 

However, when these vans are reclassified to fall within the same category as internal combustion engine vans, the first MOT test is expected to be due three years after the date of registration. A government survey of Class 7 MOT facilities in 2023 found that most facilities have a hoist capable of handling a Safe Working Load above 4,250 kg. This change is expected to reduce testing costs significantly.  The Department for Transport consulted on this modification, and it got broad support. A large number of those surveyed agreed with the idea of electric vans undergoing Class 7 MOT tests rather than heavy goods vehicle tests. The change was meant to make things easier and reduce costs, hence encouraging companies to invest in green vehicles.

Changes to the PSV and HGV Inspection Manuals 

For commercial vehicles, starting April 1, 2026, there have been revisions to the manuals used for HGV and PSV MOT examinations. These manuals set out how the MOT tests should be carried out for lorries, trailers, and buses, basically, the practical process. In the updated versions, drivers also get a revision page that provides a quick synopsis, and a black margin line runs down each page where something has been amended. Some of the more notable changes in the manuals include things like: 

• Guidance on how to inspect components such as brakes and the side guard.
• A reworking of the advice covering how to apply the load index to GB-plated weights.
• Corrosivity evaluation guidelines.
• An interpretation guide for terminology, so definitions are a bit clearer.

Tester Discipline Guidelines

The updates to the tester rules will also take effect early in 2026. The DVSA added fresh restrictions starting January 9, 2026, limiting MOT testers and Authorised Examiner Principals (AEPs) from holding MOT roles during a two-year or five-year disciplinary ban.  With the new setup, an MOT tester who has had a cessation cannot take on any MOT-related work during that cessation. Similarly, an AEP cannot take on any MOT duties if they are the AEP for a single-site authorised examiner and that entity has been given a cessation, or if they are the AEP within a multi-site authorised examiner arrangement where all sites have been issued a cessation.  These changes are intended to ensure the disciplinary measures are applied as expected and to strengthen accountability throughout the MOT test Dundee process. Closing the loopholes that would let testers drift from one role to another while under suspension has, in practice, weakened the main purpose of disciplinary action.

New Rules About Tyres, And Speed Limiters for Commercial Vehicles

For electric vans that fall in the 3,501 kg to 4,250 kg bracket, the June 2026 amendments also add updated efficiency standards and tyre tread depth requirements. The tread depth rule, at least the minimum one, has been raised from 1 mm to 1.6 mm, so it now aligns with the current Class 7 vehicles. On the speed side, the rules have been tweaked to cover zero-emission goods vehicles, specifically type N2, that can exceed 56 miles per hour, lack a speed limiter, and were first registered on or after January 1, 2005.

Real-World Effects

For fleet managers and the everyday commercial driver, these changes come with a few noticeable knock-on effects. The reclassification of electric vans could remove major barriers and open the door to a key part of the UK’s transition toward zero-emission travel. But to keep fleet performance and safety solid, operators and technicians will need to get up to speed on the inspection handbook updates immediately. Also, the introduction of new tester roles is evidence that the testing system is working better overall, and these improvements should make it even more effective.

Conclusion

With advances in vehicle technology and increased regulatory scrutiny, the MOT test process continues to evolve. Putting electric vans within the remit of the heavy vehicle MOT test up to class 7 will really help fleet managers adopt new technology more easily, cut testing costs, and make the whole process more straightforward. The refreshed inspection guides for HGVs and PSVs also offer clearer guidance for examiners and operators. There have also been stricter rules implemented regarding examiner conduct.
