How Often Should I Service My Car?

8 September 2026 · 5 min read

The basic rule — 12 months or 12,000 miles

Most manufacturers recommend a full service every 12 months or 12,000 miles, whichever comes first. Some newer cars run long-life intervals of up to 24 months or 20,000 miles, but the 12/12 rule covers most vehicles on the road.

Interim service — every 6 months for high-mileage drivers

If you do high mileage or short regular journeys (taxis, delivery drivers), an interim service sits between full services. It covers oil, filter, and core safety checks — lights, brakes, tyres, steering — without the deeper inspection of a full service. Interim keeps high-mileage cars safe and catches early wear before it becomes expensive.

Full service — the standard annual service

A full service includes all interim items plus air filter replacement and deeper checks on brakes, suspension, and steering. It typically takes 2 to 3 hours. Most cars need a full service once a year.

Major service — every 24 months for complete care

A major service is the comprehensive option, covering all full service items plus spark plugs, pollen filter replacement, and 60-point checks on cooling, transmission, and wheel bearings. It is due every 24 months or 24,000 miles and takes 3 to 4 hours. After a major service, your car gets the deepest level of inspection we offer.

What to do if you do not know your service history
