You can book your MOT up to one month minus one day before your current MOT expires and still keep the same renewal date for the following year. If you take the test earlier than that window, your MOT will start from the new test date, which means you lose the extra days that could have been carried over.
Many drivers misunderstand this rule and either book too late or too early. Booking too late risks driving illegally, while testing too early shortens your MOT cycle unnecessarily. The safest and smartest choice is to stay within the official window.
Booking early is also about convenience. It allows time for repairs, gives you flexibility to choose a preferred date, and helps you avoid the seasonal rush when most garages are fully booked. At An Tyres, we help drivers plan their MOTs properly so they can stay road safe and stress free all year round.
What the MOT Early Booking Rule Means
Every car in the UK must pass an MOT test once it reaches three years of age. The test confirms that your vehicle meets national safety and environmental standards set by the Driver and Vehicle Standards Agency.
The rule about early booking is simple. You can take your MOT up to one month minus one day before your current certificate expires and still keep the same renewal date.
For example, if your MOT expires on 15 July, you can take the test on or after 16 June and your next MOT will still expire on 15 July the following year. If you decide to test earlier than 16 June, the new certificate will start from that earlier date.
This policy helps drivers plan better while maintaining consistent renewal cycles across the country. It also prevents drivers from skipping safety checks for too long, keeping both drivers and other road users safer.
Why Booking Early Is a Smart Choice?
Many people wait until the last week before their MOT expires, only to find that garages are fully booked or that their vehicle fails the test with no time left for repairs. Booking early gives you peace of mind and flexibility.
When you book your MOT early, you can:
- Secure a convenient date before the rush begins
- Allow time for any repairs if something fails
- Avoid driving with an expired MOT, which can lead to a fine of up to one thousand pounds
- Combine the test with other car checks, such as servicing or tyre replacement
At An Tyres, we recommend that our customers mark their MOT expiry date as soon as they receive the last certificate. We also offer a reminder service that alerts you before your early booking window opens, ensuring you never miss your chance.
Early planning not only keeps you legal but also prevents unexpected costs from last minute failures or rushed repairs.
Examples of MOT Date Calculations
To make it easy, here are a few worked examples of how the early booking rule applies.
- If your MOT expires on 20 September 2025, the earliest you can test and keep the same renewal date is 21 August 2025.
- If your MOT expires on 10 February 2025, you can test from 11 January 2025, and your new MOT will expire on 10 February 2026.
- If your MOT expires on 30 November 2025, but you take the test on 10 October, your next MOT will expire on 9 October 2026.
At An Tyres, we can calculate your exact earliest valid test date using your registration number. We can also help you plan ahead by sending reminders, checking available slots, and suggesting convenient dates to combine your MOT with a tyre service or brake inspection.
What Happens If You Test Too Early?
Testing too early might sound helpful, but it actually means your next MOT will expire earlier the following year. For example, if your car’s MOT expires on 30 November but you decide to test on 10 October, your new MOT will now expire on 9 October the next year. You lose over seven weeks of coverage.
While you can book your appointment months ahead, always ensure the actual test date is within the early booking window. This is the only way to keep your original renewal date.
If you are unsure about your correct testing window, the team at An Tyres can check it for you instantly and help you schedule your test at the perfect time.
Can You Book the MOT Months Ahead?
Yes, you can book months ahead to secure a slot that suits your schedule. Many drivers prefer to book early to avoid disappointment during busy months, especially around March, April, September and October.
However, the key is to remember that the MOT must be carried out within the one month minus one day period to preserve your renewal date.
For instance, if your MOT expires on 12 June, you can book your test as early as February or March, but the actual testing day should fall on or after 13 May.
At An Tyres, we allow our customers to reserve appointments in advance and adjust the exact test date closer to their window. We also offer text or email reminders, so you always stay on track.
Early MOTs in Northern Ireland
In Northern Ireland, MOTs are run by the Driver and Vehicle Agency instead of the DVSA. The system there is slightly different.
The first MOT for a car in Northern Ireland is due four years after its first registration rather than three years as in England, Scotland and Wales. You can still book in advance, but DVA test centres often experience long waiting times.
If you are within ten days of your vehicle tax expiring and cannot get a test slot, you can apply for a short notice appointment. The same early booking principle applies there too. If your test is taken within one month of expiry, you will keep your existing renewal date.

Common MOT Myths Explained
Myth 1: There is a grace period after your MOT expires.
This is false. You cannot drive once your MOT has expired unless you are travelling directly to a pre booked test.
Myth 2: Testing early gives you a longer MOT.
Only if it falls inside the one month minus one day window. Testing earlier than that resets your MOT to the new test date.
Myth 3: MOT checks everything in the car.
The MOT focuses on safety and emissions. It does not cover the engine, clutch or gearbox performance.
Myth 4: New cars do not need any checks until the first MOT.
Even though your car is exempt for the first three years, regular servicing, tyre checks and brake inspections are still important for safety and performance.
How to Prepare Before Your MOT
Preparing before your MOT can make the difference between passing first time and facing a retest.
Here are simple checks you can do at home.
- Check your tyre tread depth is at least one point six millimetres and that tyres are properly inflated.
- Test every light, including headlights, brake lights, indicators and number plate lights.
- Clean your windscreen and make sure your wiper blades are in good condition.
- Top up oil, screen wash and brake fluid levels.
- Ensure your number plates are clean and easy to read.
An Tyres offers free pre MOT checks to identify potential issues before your test day. This small step often saves time and money by avoiding minor failures.

The earliest you can book your MOT is one month minus one day before your current certificate expires. Testing earlier than that resets your renewal date, which means you could lose valid time. There is no grace period after expiry and driving without a valid MOT can result in fines and penalties.
