How to book your NCT in Ireland (and what to do when there are no slots)

Check your due date before anything else

The test due date follows your car's first registration, not the calendar year. A car is first tested at four years old, then every two years, and annually once it passes ten years old.

The NCTS website has a due-date check by registration number, which is worth doing before you book — booking more than 90 days earlier than the due date counts as a voluntary early test, and the new certificate then runs from the test date rather than your original cycle.

Book on the official site only

Bookings are made on ncts.ie. NCTS has publicly warned that other sites offer to book a test for a fee — they are not official, and there is no need to pay anyone to secure an appointment.

You can also book by phone with the NCTS booking line, or by email. You need your registration number and a card; if you are changing or cancelling an existing appointment you also need the booking ID from your letter.

Why there seem to be no appointments

The slots visible online are roughly a third of the real capacity. NCTS releases the rest about two weeks ahead, once staffing for that week is confirmed. So an empty calendar today does not mean an empty calendar in ten days.

Each centre also publishes an average booking lead time, which is the honest way to judge how far ahead you need to plan at your local centre.

The priority list: the step most people skip

If nothing suitable appears, the booking process offers a priority list. NCTS aims to find those on it an appointment within 28 days, and it costs nothing to join.

It is the correct move when your disc is close to expiry: joining the list and taking a later slot is far better than driving untested while you wait for a cancellation to appear.

What to bring on the day

Retests are typically scheduled much faster than a first appointment — usually within a few days — but the simplest way to avoid one is a ten-minute check of the obvious items before you go.

• The vehicle registration certificate or licensing certificate for the car.
• Your driving licence or Public Services Card as identification.
• A car in testable condition: tyres, lights and wipers checked, boot cleared, no warning lights.

Keeping the date from creeping up on you

The NCT reminder is posted to the address on the vehicle record, so it goes astray easily after a move or a change of ownership. The legal responsibility stays with the owner regardless.

Set your own reminder about two months before the due date: that is enough runway to book, and to join the priority list if the calendar is full. In MiRicordi you can save the NCT date as a repeating reminder next to motor tax and insurance, attach a photo of the certificate, and get the alert even with the app closed.
