For many UK drivers, the MOT has a habit of sneaking up on you. One minute you’re navigating school runs, commuting through morning traffic or planning a weekend away, and the next you’re scrambling to book a test before the certificate runs out. As we move into 2026, with repair costs rising and cars staying on the road longer, being prepared has never mattered more.
A failed MOT doesn’t just mean inconvenience — it often brings unexpected repair bills, repeat test fees and time off the road, all of which can quickly add up. That’s why more motorists are choosing to get ahead of the problem rather than deal with a failure on test day. Taking the time to avoid unexpected MOT failures with a professional pre MOT check at Dexel Tyre & Auto Centre helps spot common issues early, reduces stress and saves money — especially when small faults are cheaper to fix before they turn into official failures.
A little preparation before your MOT can make the whole process much easier. There are several simple checks you can carry out yourself before your MOT appointment. Here are six of the most important ones every UK driver should focus on in 2026.
1. Make Sure All Your Lights Are Working
Lighting faults remain one of the most common MOT failure reasons across the UK. Before your test, check headlights, sidelights, indicators, brake lights and number plate lights.
This is particularly important during darker winter months, when lights are used constantly on early morning commutes or evening drives. Ask someone to press the brake pedal for you or simply check the reflections against a wall.
2. Inspect Tyres for Tread and Damage
Tyres suffer badly on British roads, especially with potholes becoming more widespread. The legal minimum tread depth is 1.6mm, but many drivers don’t realise how quickly tyres can wear.
Use the 20p test and look for cracks, bulges or uneven wear. Don’t forget to check all four tyres, not just the front ones.
A thorough pre-MOT check here doesn’t just help with the MOT — it also improves fuel efficiency and road safety.
3. Windscreen, Wipers and Washer Fluid
With UK weather being as unpredictable as ever, your windscreen setup needs to be spot on. Cracks or chips in the driver’s line of sight can result in a failure, as can worn or ineffective wipers.
Top up washer fluid and test the jets. This is especially relevant after winter, when grit and road salt can clog systems or damage blades.
4. Dashboard Warning Lights and Brakes
When you turn the ignition on, all warning lights should illuminate briefly and then switch off. Any light that stays on — especially engine, ABS or airbag warnings — could cause a failure.
Listen out for unusual brake noises too, such as grinding or squealing, particularly if you do a lot of stop-start driving in town.
This is where a professional pre-MOT check can be invaluable, as some issues aren’t obvious without proper inspection.
5. Seatbelts and Seats
Seatbelts are essential for vehicle safety and are checked during an MOT. Make sure they pull out, retract, and lock properly without any strain. Also, check that the seats are securely fastened and can be adjusted as needed.
If you often carry pets, children, or large items, your vehicle may experience wear and tear that is not always easy to spot. Adding this check to your pre-MOT list can help you find problems before your test.
6. Number Plates and Overall Visibility
Number plates must be clean, readable and securely attached. Cracked plates or incorrect spacing can cause a failure, something many UK drivers don’t expect.
Before your MOT, give the car a quick clean — windows, mirrors and plates included. It improves visibility and makes sure nothing important is missed.
Making MOT Season Easier in 2026
Due to the rising cost of living in the UK, most motorists would prefer not to fail their MOT and incur the additional costs of repairs and retesting. A professional pre-MOT check enables you to control costs, plan ahead for any necessary repairs to your vehicle, and keep it in a roadworthy condition for all journeys. Whether you’re commuting to work, taking your children to after-school clubs, or heading off on holiday, having the peace of mind that your vehicle can pass an MOT can significantly reduce stress on test day.
