This guide explains the three main types of car service, how often you need each one, and why skipping a service is rarely worth it.
What Is a Car Service?
A car service is a routine check carried out by a mechanic to make sure your vehicle is running safely and efficiently. Think of it like a health check for your car. A trained mechanic inspects key parts, replaces worn items, and tops up fluids before small problems turn into big ones.
A service is not the same as an MOT. An MOT test checks that your car meets the minimum legal safety standards set by the government. A service goes further than that, looking at how well your car is actually running, not just whether it passes a legal threshold. You can find more about what an MOT involves on the GOV.UK MOT guide.
The Three Main Types of Service
There are three types of service most UK garages offer. Here is a quick breakdown of each one.
| Service Type | Recommended Interval | Who It Is For |
|---|---|---|
| Interim Service | Every 6 months or 6,000 miles | High-mileage drivers |
| Full Service | Every 12 months or 12,000 miles | Most drivers |
| Major Service | Every 24 months or 24,000 miles | Long-term maintenance |
Interim Service
An interim service is a lighter check designed to bridge the gap between full services. It is best suited to drivers who cover a high number of miles in a short space of time, such as those who use their car for work or drive long distances regularly.
It typically includes an engine oil and filter change, a check of your brakes, tyres, steering, lights, and fluid levels. It is not a replacement for a full service, but it helps catch problems early.
Full Service
A full service is the most common type and is recommended for the majority of UK drivers. It covers everything in an interim service, plus much more, including checks on the air filter, spark plugs, fuel filter, exhaust, battery, and suspension.
Most drivers should book a car service once a year or every 12,000 miles, whichever comes first. If you are unsure which applies to you, check your vehicle’s owner manual, as some manufacturers have their own specific recommendations.
Major Service
A major service is the most thorough option. It is usually carried out every two years or every 24,000 miles and covers all the checks in a full service, along with additional items like the coolant, brake fluid, and timing belt (depending on your vehicle).
If you have never had a major service, or it has been a while, it is worth speaking to a local garage to find out what your car needs.
Why Skipping a Service Is a False Economy
It might be tempting to skip a service to save money in the short term. But this often costs more in the long run.
When small faults go unnoticed, they can develop into serious mechanical problems. A worn brake pad, for example, is cheap to replace early but can lead to a damaged brake disc if left too long, which is significantly more expensive. A dirty air filter reduces fuel efficiency, meaning you spend more at the pump over time.
Regular servicing also protects your car’s value. A full service history makes a vehicle far more attractive to buyers, so keeping on top of it is worthwhile even if you plan to sell one day.
If you are ever unsure what is going on under the bonnet, a car diagnostics check can help identify any issues your car’s computer has logged, giving a mechanic a clear starting point.
How Do I Know When My Car Is Due a Service?
Most modern cars have a service warning light on the dashboard. When this comes on, do not ignore it. Book your car in as soon as you can.
If your car does not have a warning light, or you are not sure when the last service was carried out, check the service book in your glovebox. This will show you the date and mileage of any previous services. If there is no record, it is always a good idea to book a full service to establish a fresh baseline.
