How often should you service your car? UK guide for 2026
Most cars in the UK should have a full service every 12 months or 12,000 miles, whichever comes first. If you cover a lot of miles, an interim service roughly every 6 months or 6,000 miles fills the gap between full services. Your car’s handbook or service book has the definitive schedule, and it always beats a general rule of thumb.
This guide explains how often each type of car needs servicing, what interim, full and major services include and cost, how a service differs from an MOT, whether skipping one affects your warranty or insurance, and how to keep costs down without cutting corners.
Last updated 29 September 2026. Service prices come from our car service cost guide. Service intervals were checked against RAC guidance (see the sources at the end).
Key takeaways
- Full service: every 12 months or 12,000 miles, whichever comes first.
- Interim service: roughly every 6 months or 6,000 miles, mainly for high-mileage drivers, between full services.
- Major service: often every two years or 24,000 miles, if your car’s schedule includes one.
- Typical prices at an independent garage: about £100 to £180 for an interim, £180 to £300 for a full and £250 to £450 for a major service.
- A service is not an MOT. The MOT is a legal roadworthiness test; a service is preventative maintenance.
- You do not have to use a main dealer to keep a manufacturer’s warranty, as long as the schedule is followed, suitable parts are used and the work is recorded.

How often should a car be serviced?
The most widely used guideline, and the one the RAC gives, is a service at least every 12 months or 12,000 miles, whichever comes first. The time limit matters as much as the mileage, because engine oil, brake fluid and coolant deteriorate with age even if the car barely moves.
| Your situation | How often to service |
| Average driver (roughly 7,000 to 12,000 miles a year) | One full service every 12 months |
| High-mileage driver (over 12,000 miles a year) | A full service every 12 months or 12,000 miles, plus an interim service about every 6 months or 6,000 miles |
| Low-mileage driver | Still every 12 months, because fluids age with time as well as miles |
| Mostly short trips or stop-start traffic | Consider servicing sooner or adding an interim service, because the engine rarely gets fully warm |
| Diesel car with a DPF, used mainly around town | Ask your garage whether extra oil changes make sense; the DPF may not regenerate properly on short trips |
| Hybrid | Usually annual. Ask the garage to check the brakes carefully, because regenerative braking can mean the friction brakes get less use |
| Electric car | Follow the manufacturer’s schedule, which is often every 12 months to 2 years depending on the make |
| Older car (10+ years or 100,000+ miles) | Many garages suggest more frequent checks, such as an interim service between full services |
| Car under manufacturer warranty | Follow the service schedule exactly and keep proof of every service |
Some newer cars have a service indicator that works out when a service is due based on how you drive. If yours does, follow it, but do not ignore the calendar: a car that does few miles still needs an annual check.
Interim, full and major service compared
Garages usually offer three levels of service. Names and contents vary between garages and manufacturers, so always ask for an itemised quote.
| Service | Typical timing | What it usually includes | Typical price at an independent garage |
| Interim | Every 6 months or 6,000 miles, mainly for high-mileage drivers | Engine oil and oil filter change, fluid checks and top-ups, and inspection of brakes, tyres, lights, steering and suspension | £100 to £180 |
| Full | Every 12 months or 12,000 miles | Everything in an interim service, plus an air filter replacement and more detailed checks of the cooling system, drive belts, battery and exhaust. Many garages also run a diagnostic check on newer cars | £180 to £300 |
| Major | Often every 2 years or 24,000 miles | The checks from a full service, plus items that do not need replacing every year, such as the cabin filter, diesel fuel filter, spark plugs and brake fluid, depending on the car | £250 to £450 |
Main dealers generally charge more, and the price also depends on your car, your region and the parts and oil it needs. As a rough guide by car size:
- Small car (Fiesta, Corsa, i10): interim £90 to £140, full £150 to £230
- Family car (Focus, Golf, Octavia): interim £110 to £160, full £180 to £280
- Large or premium car (3 Series, XC60, Discovery Sport): interim £140 to £200, full £250 to £400
For a full breakdown, including electric car servicing, read our car service cost guide.
Which service do you need?
- Under about 12,000 miles a year: book one full service a year.
- Over 12,000 miles a year: book a full service each year and add an interim service about six months later.
- Two years since your last major service: check your schedule and ask whether a major service is due.
- Not sure what your car needs: check the handbook or service book, or ask two or three garages for itemised quotes and compare the lists.
- Not sure what was done last time: look at the service book stamps or invoices, so you do not pay for the same work twice.
What happens during a car service?
A mechanic works through a checklist based on the manufacturer’s schedule and the type of service you booked. The RAC says an interim service takes around an hour and a full service up to an hour and a half, although some garages will keep the car for longer. A typical service includes:
- Engine oil and oil filter change
- Air filter replacement (full and major services)
- Checks and top-ups of brake fluid, coolant, power steering fluid and screenwash
- Brake inspection, including pads, discs and brake lines
- Tyre checks for tread depth, pressure and damage
- Lights, wipers and horn
- Battery and charging system check
- Steering, suspension, exhaust and drive belt checks
- Diagnostic scan for stored fault codes on newer cars
- A road test before and after the work
Our guide to what a car service includes goes through the checklist in more detail.
Service vs MOT: what is the difference?
| Car service | MOT test | |
| Legal requirement? | No, but strongly recommended | Yes, for most cars once they are three years old |
| How often? | Typically every 12 months or 12,000 miles | Every 12 months after the first test |
| Purpose | Preventative maintenance: replace worn parts and fluids, and catch problems early | Checks the car meets minimum road safety and environmental standards on the day of the test |
| Result | No pass or fail; the garage gives you a report and recommendations | Pass or fail, recorded on the national MOT database |
| Includes an oil change? | Usually yes | No |
A service does not replace an MOT, and an MOT pass does not mean the car has been serviced. Many drivers book both together, and it can help to service the car before the MOT so that small faults are fixed first. Our guide on how to avoid failing your MOT lists the quick checks worth doing beforehand, and the official rules are on GOV.UK’s Getting an MOT page.
What happens if you skip a service?
- Safety: worn brake pads, tyres and fluids are easy to miss without an inspection.
- Cost: small issues that a service would have caught can turn into larger repairs, such as a failed cambelt, a worn clutch or a blocked filter.
- MOT failures: lights, brakes, tyres and wipers are all MOT items that a service would normally check.
- Warranty: if your car is under a manufacturer’s warranty, read the terms. Warranties usually require servicing to the manufacturer’s schedule, and you may need to show proof.
- Resale value: buyers and dealers prefer a car with a full, documented service history.
Insurance is a slightly different matter. Missing a service will not automatically invalidate a policy, but you are expected to keep your car roadworthy. An insurer may question a claim if the cause was neglected maintenance, such as illegal tyres or failed brakes.
Do you have to use a main dealer to keep your warranty?
No. In the UK you can generally use an independent garage without voiding a manufacturer’s warranty, provided the work follows the manufacturer’s service schedule, uses parts of matching quality and is properly recorded. If you are unsure, check the warranty terms or ask the manufacturer before you book.
When choosing a garage:
- Ask for a written, itemised quote and check what is included, such as oil, filters, labour and VAT
- Read recent independent reviews and ask whether the garage guarantees its work
- Ask the garage to stamp the service book or give you a detailed invoice
- Agree in advance that they will call you for approval before doing any extra work
Signs your car needs a service sooner
- A service or warning light on the dashboard (see our guide to dashboard warning lights)
- Grinding, squealing or knocking noises from the engine or brakes
- Brakes that feel spongy, pull to one side or take longer to stop
- A rough-running engine, stalling, or noticeably worse fuel economy
- Dark, gritty or low engine oil on the dipstick
- Vibrations through the steering wheel, pedals or seats
- Unusual smells, such as burning oil or hot brakes
Checks you can do between services
A service does not replace basic maintenance. Ten minutes a month can catch most everyday problems, and our car maintenance checklist goes into more detail.
| Check | How often | What to look for |
| Engine oil level | Monthly and before long trips | Between the minimum and maximum marks on the dipstick, on level ground. See how to check your engine oil |
| Tyre pressure | Monthly and before long trips | Match the figures in the handbook or on the door frame. See our tyre pressure guide |
| Tyre tread and condition | Monthly | At least 1.6mm of tread, and no cuts, bulges or cracks. See the tyre tread depth test |
| Coolant level | Monthly, with the engine cold | Between the minimum and maximum marks |
| Screenwash and wipers | Monthly | Topped up, and wipers clearing the screen without smearing |
| Lights | Monthly | All bulbs, brake lights and indicators working |
| Battery | Before winter | Clean, tight terminals and a car that starts easily. See our car battery guide |
How to keep servicing costs down
- Get itemised quotes from two or three garages, including independent ones, and compare like for like
- Ask whether the garage offers a fixed price, and what is not included
- Book your service and MOT together if the garage offers a package
- Keep up with small jobs such as tyre pressure and fluid levels, so they do not turn into big ones
- Ask the garage to explain any recommended extras and which are urgent and which can wait
- Do not skip services to save money, because worn parts usually cost more later
Why a service history matters
A complete service history shows buyers and dealers that a car has been looked after, which can help you sell it faster and for a better price. It is also the proof you need if a warranty claim is ever questioned.
- Keep the stamped service book, or the garage’s detailed invoices, in one place
- Note the mileage and date of every service and any parts replaced
- Keep MOT certificates, and remember you can check any car’s MOT history free on GOV.UK’s Check MOT history service
Frequently asked questions
Can I service my car every two years?
For most petrol and diesel cars, no. Oil and other fluids degrade with time as well as mileage, so an annual service is the safer choice. Only stretch the gap if the manufacturer’s schedule allows it, as some electric cars do.
Do I need a service if I barely drive?
Yes. Engine oil, brake fluid and coolant deteriorate with age even when the car is rarely used, so a low-mileage car still needs a service at least once a year.
How long does a car service take?
According to the RAC, an interim service takes around an hour and a full service up to an hour and a half. A major service usually takes longer, and some garages keep the car for most of the day.
Is an interim service enough?
If you cover less than about 12,000 miles a year, a full service once a year is the better choice. An interim service is designed for high-mileage drivers and is best used between full services.
Does a car service include an MOT?
No. A service and an MOT are separate. Some garages offer both as a package, so check that the MOT is listed on your invoice.
What should I do if my service light comes on?
Check your handbook. Some service indicators are based on mileage and some on time or driving style. Book a service soon, and do not ignore the light if a separate warning light comes on with it.
Is servicing cheaper at an independent garage?
Usually. Main dealers generally charge more than independent garages, but the best choice is the one that follows your manufacturer’s schedule, uses suitable parts and records the work.
Can I service my car myself?
You can do basic checks such as fluid levels and tyre pressure yourself. A full service with a stamped record is better for warranty and resale purposes, especially on newer cars.
