How Often Should You Service Your Car in the UK?
Many UK cars need a service every 12 months or 12,000 miles. Here’s why your own schedule may differ and how your driving changes the answer.
Most cars in the UK need a full service every 12 months or 12,000 miles, whichever comes first. That’s the general rule the RAC gives, but your own car’s schedule, set by the manufacturer and printed in the handbook or service book, always takes priority. GOV.UK also points drivers to the handbook for the servicing schedule.
Why time matters as well as mileage
People who drive 4,000 miles a year often assume they can skip a service. Oil doesn’t work like that. It ages in the engine even when the car is parked, and short trips can be harder on it than long ones because the engine may never fully warm up. Rubber parts, brake fluid and coolant also age whatever the odometer says. A low-mileage car still needs looking after, which is why the time limit sits alongside the mileage limit.
Fixed and variable schedules
Many modern cars don’t use one simple interval. Some have a fixed schedule. Others use a variable or long-life schedule, where the car works out when a service is due based on how it’s driven, and shows a reminder on the dash. These can stretch well beyond a year for some cars, but they depend on the correct oil being used and the car being driven in the conditions the schedule assumes.
If you’re not sure which your car is on, check the service book or look up the handbook. A service light doesn’t always mean a problem, and it can usually be cleared as part of the service.
The three service levels
You’ll see these names used by most garages, although what’s included varies from one to the next:
- Interim service: usually every 6 months or 6,000 miles. An oil and filter change with a basic inspection. Useful for high-mileage drivers, but not a replacement for a full service.
- Full service: usually every 12 months or 12,000 miles. Oil, filters and a much wider inspection of the car’s safety and mechanical systems.
- Major service: often every 24 months. A full service plus extra items such as brake fluid and, depending on the schedule, items like a cabin filter.

When you might service more often
A set interval assumes fairly normal use. It’s worth going sooner if most of your journeys are short trips, you do a lot of stop-start town driving, you tow regularly, or your car has a hard life as a work vehicle. The same goes if you’ve bought a used car with no reliable history. Without records, a service gives you a known starting point.
In the gaps between services, keep an eye on the basics. GOV.UK says to check oil, coolant, brake fluid, the battery, washer fluid and tyres regularly, following your handbook. If you’re topping up oil more often than you used to, tell your mechanic.
Does a car service have to be done by law?
The legal test for road use is the MOT, not a service. It’s also your duty to keep the car roadworthy at all times, and GOV.UK makes the point that a vehicle can be unsafe even with a current MOT certificate. A service and an MOT do different jobs: the MOT checks that the car met set standards on the day, while a service replaces worn items and aims to keep the car reliable.
Will independent servicing affect my warranty?
According to the RAC, you don’t have to use a dealer to keep a manufacturer warranty, as long as the car is serviced at or before the set intervals, with the correct parts and fluids, and you keep records. A stamped book and an itemised invoice showing the oil grade matter here. Dealer extended warranties can have their own rules, so read yours before booking.
What we can do
If it’s just the oil that’s due, an oil service can often be done at your home or workplace. For the annual service, our full car service covers a wider check. Send us your make, model, mileage and when it was last serviced, and we’ll tell you what looks due.
