Knowing the types of car service available is the first step to keeping your car mechanically sound — and choosing the right level means you protect your vehicle without spending more than you need to.
Most drivers aren't sure whether they need an interim, full, or major service, or whether the quote from their garage is actually fair. If you drive a hybrid or electric car, you might not know whether standard servicing applies to you at all.
This guide explains exactly what each service type covers, what you should expect to pay across different garage types, and how to decide which service is right for your car and driving habits.
Why do you need a car service?
If your car has been running without a service for a while, you might be wondering what you're actually missing. A car service maintains your vehicle's mechanical health between MOT tests, catching small faults before they become expensive repairs.
The MOT test is a legal requirement for cars over three years old, but it only checks roadworthiness on a single day. A service goes further, maintaining the systems that keep your car reliable over time.
If your car is still under the manufacturer's warranty, regular servicing is not optional. Skipping it can invalidate your cover entirely. The next step is understanding which of the three car servicing types applies to your situation.
Types of car service
| Feature / Service Type | Interim Car Service | Full Car Service | Major Car Service |
|---|---|---|---|
| Recommended Interval | Every 6 months / 6,000 miles | Every 12 months / 12,000 miles | Every 24 months / 24,000 miles |
| Time Required | ~1 hour | Up to 1.5 hours | 3–4 hours |
| Engine Oil & Filter Change |  | | |
| Brake Fluid Check | | | |
| Tyre & Wheel Inspection | | | |
| Battery Test / Check | | | |
| Steering & Suspension Check | | | |
| Exhaust Check | | | |
| Air Filter Change |  | | |
| Cabin Air Filter Replacement | | | |
| Detailed Brake Inspection | | | |
| Seatbelt & Airbag Testing | | | |
| Diagnostics Scan | | | |
| Spark Plug Replacement | | | |
| Timing Belt Inspection | | | |
| Wheel Alignment Check | | | |
| Fuel System Inspection | | | |
| Power Steering Check | | | |
| Best For | High mileage drivers / mid-year check | Typical annual maintenance | Deep, comprehensive service / high mileage vehicles |
Interim car service
If you cover high mileage or simply cannot wait a full year between checks, an interim service is your starting point. Recommended every six months or 6,000 miles, whichever comes first, it takes around one hour and covers the essentials: engine oil and filter change, brake fluid check, tyre and wheel inspection, battery test, steering and suspension assessment, and exhaust check.
Choose this if you drive more than 12,000 miles a year or want a mid-year health check between full services.
Full car service
A full service is recommended every 12 months or 12,000 miles. It builds on everything in an interim service and adds an air filter change, cabin air filter replacement, battery and charging system check, detailed brake inspection, seatbelt and airbag testing, and a complete diagnostics scan covering up to 80 individual checks. Expect it to take up to one and a half hours.
Choose this if you drive a typical annual mileage and want a thorough, all-round check carried out once a year.
Major car service
Every 24 months or 24,000 miles, your car benefits from a major service, which takes three to four hours. It covers everything in a full service, then goes further. Spark plugs (the components that ignite fuel in your engine) are replaced, and the timing belt (the belt that keeps your engine's internal parts moving in sync) is inspected. You also get a brake fluid flush, wheel alignment check, cabin filter replacement, fuel system inspection, power steering component check, and a full suspension review.
Choose this if your car is due a comprehensive health check or has accumulated high mileage since its last major service.
How much does a car service cost?
Not knowing what a service should cost makes it impossible to judge a fair quote. Here are the 2026 market ranges to use as your benchmark (source: UK Cost Guide, 2026).
| Service type | Typical cost |
|---|---|
| Interim service | £90–£160 |
| Full service | £150–£260 |
| Major service | £250–£420 |
These figures exclude additional repairs. If your garage identifies worn brake pads, expect to pay £100–£180 on top. A timing belt replacement adds £350–£650. These are separate jobs, not part of the service fee itself.
Cost by provider tier (UK Cost Guide, 2026):
| Provider | Full service | Major service |
|---|---|---|
| Main dealership | £250–£380 | £350–£520 |
| Independent garage | £150–£220 | £250–£400 |
| Mobile mechanic | £130–£190 | £220–£350 |
Independent garages and mobile mechanics typically offer the best value, especially once your manufacturer warranty has expired.
Location matters too. A full service in London averages £200–£300. The same service in a smaller city like Bradford averages £130–£210. That gap is worth knowing before you assume your local quote is high.
Servicing your hybrid or electric car
If you've recently switched to an electric or hybrid car, you might be wondering whether your usual service schedule still applies. It does — but what happens during that service changes significantly.
Electric car service focuses on components petrol cars don't have, while cutting out several jobs entirely.
EV-specific checks include:
- Battery health and efficiency assessment
- High-voltage (HV) system visual inspection
- Regenerative braking system check
- Software and firmware updates
- Cooling system checks for battery thermal management
Eliminated for pure EVs: oil changes, spark plug replacement, and timing belt service.
That difference adds up. EVs cost approximately 29% less to service over five years, averaging £4,022 versus £5,709 for petrol equivalents — a saving of around £1,687 (RAC, 2025).
Service intervals are longer too. The Renault Zoe is serviced every 18,000 miles, the Volkswagen ID.3 and ID.4 annually or every 18,000 miles, and Hyundai EVs move to 20,000-mile intervals from year two.
EV batteries also carry a separate eight-year manufacturer guarantee, which runs alongside the standard vehicle warranty of three to seven years. Keep your service records current to protect both.
If you drive a hybrid car, expect most standard petrol service checks alongside the EV-specific items above — both systems need attention.
Can you get a service at home?
If a weekday garage visit doesn't fit your schedule, a mobile mechanic can come to you. According to Halfords Mobile Expert data, mobile mechanics now cover around 75% of UK households, carrying out interim services, full services, oil changes, brake pad replacement, and battery fitting at your home or workplace. Because they operate without the overhead costs of a fixed garage, you'll typically pay 20–30% less than at a traditional garage. Complex jobs like timing belt replacement or gearbox work still need a fixed workshop.
Conclusion
Stick to your service schedule, use the right service type for your mileage, and keep your documentation in order. That's what protects your car's performance, its warranty, and its value long term.
