What does a car service include? Interim, full & major services explained

At a glance:

• A car service is a routine health check covering oil changes, fluid top-ups, brake and tyre inspections, and component replacements.
• UK garages offer three levels: an interim service (every 6 months / 6,000 miles, ~£80–£150), a full service (every 12 months / 12,000 miles, ~£160–£280), and a major service (every 24 months / 24,000 miles, ~£200–£400).
• A service is not the same as an MOT — both are needed.
• Skipping a service can lead to undetected safety issues, higher repair costs, and a lower resale value.

What are the main types of car service?

Interim service

An interim service is a basic health check recommended every 6 months or 6,000 miles — ideal for high-mileage drivers or those who use their vehicle for frequent short trips. It keeps essential components in good working order and helps prevent minor issues from escalating. It typically includes:

• Engine oil change: Draining old oil and replacing it with fresh lubricant to protect engine components.
• Oil filter replacement: Installing a new filter to remove contaminants from the engine oil.
• Fluid level checks and top-ups: Including brake fluid, engine coolant, screen wash, and power steering fluid.
• Brake inspection: A visual check of brake pads, discs, and pipes for wear or damage.
• Tyre check: Inspecting tyre pressure, tread depth, and overall condition (including the spare).
• Battery health test: Checking the battery's charge level and terminals.
• Light and horn check: Ensuring all exterior lights (headlights, indicators, brake lights) and the horn function correctly.
• Steering and suspension check: A basic inspection of shock absorbers and steering joints.
• Windscreen and wipers: Checking for chips in the glass and the condition of the wiper blades.
• Visual exhaust inspection: Checking for leaks or corrosion in the exhaust system.

Full service

A full service covers everything in an interim service, plus more thorough checks and component replacements. Recommended every 12 months or 12,000 miles, it is the standard annual car servicing most UK drivers need. Additional items include:

• Air filter replacement: Ensures clean airflow to your engine
• Cabin filter check: Improves air quality inside your vehicle
• Coolant level and cooling systems check: Prevents overheating
• Thorough brake inspection: Assesses brake pad and brake disc condition
• Suspension and shock absorber checks: Identifies wear that affects handling and comfort

Major service

A major service is the most thorough option, recommended every 24 months or 24,000 miles. It includes everything from a full service, plus:

• Spark plug replacement: Ensures efficient engine firing and prevents misfires that damage the engine over time
• Fuel filter replacement: Keeps your fuel system clean and protects the fuel pump
• Brake fluid replacement: Brake fluid absorbs moisture over time, lowering its boiling point — degraded fluid can reduce stopping effectiveness in hard braking situations
• Gearbox and clutch inspection: Checks transmission health
• Drive belt check: Identifies wear before failure occurs
• Power steering fluid check: Maintains smooth steering operation
• Radiator and coolant hoses inspection: Prevents leaks and overheating
• Condition of road springs and wheel bearing checks: Ensures suspension integrity
• Electronic diagnostic scan: Reads stored fault codes from your car's engine management system — identifies issues your car has already logged internally but hasn't yet shown as a dashboard warning light

Interim vs full vs major service: comparison table

Here's how the three levels compare side by side:

The right choice depends on your car's age, mileage, and manufacturer service schedule. Ask your local garage or Point S centre for guidance if you're unsure.

Is a car service the same as an MOT?

No — both serve different purposes. An MOT is a legal requirement checking for visible failures at the time of the test, but won't flag issues like degraded brake fluid or a worn air filter. A car service is preventative maintenance: replacing fluids and consumables before they cause problems. Your MOT confirms your car is roadworthy today; your service keeps it that way.

Many drivers book their MOT and service together to save time and, in many cases, money. Find your nearest Point S centre to book both at the same time.

What's not included in a car service

A standard servicing package covers inspection, fluids, and consumables. These items are typically charged separately:

• Timing belt/chain replacement — essential at the manufacturer's interval, but not included
• Brake pad or disc replacement — inspected, but replacement is extra if needed
• Tyre replacement — condition is checked, but new tyres are not part of the service
• Air conditioning regas , wheel alignment correction, and complex diagnostic work — all add-ons

Point S tip: Your technician will always provide a clear, no-obligation quote before any additional work is carried out.

How much does a car service cost in the UK?

In 2026, expect to pay around £80–£150 for an interim service, £160–£280 for a full service, and £200–£400 for a major service. Prices vary by make, model, and location. Find your nearest Point S centre for a personalised quote.

How often should you service your car?

Most manufacturers recommend a regular service at least once a year or every 10,000–12,000 miles — check your service book for your specific car's requirements. For hybrid cars and EVs, standard intervals still apply, but checks differ; always confirm what's included when booking.

Following the manufacturer service schedule gives you peace of mind and protects your warranty. Green Flag research (Direct Line Group, 2025) found 73% of second-hand buyers prioritised a full service history — the best way to protect resale value. Don't skip: minor issues like degraded brake fluid develop silently and give no warning before causing a costly breakdown.

Frequently asked questions

Does a full service include an oil change?

Yes — a full service always includes an engine oil and filter change as a standard part of the package. Learn more about oil and filter change with our complete guide!

Does a car service include repairs?

No — a car service covers checks and consumable replacements. If a problem requiring repair is found, your technician will advise you separately with a clear quote before any work is done.

Does a full car service include spark plugs?

Spark plugs are replaced as part of a major service, not a full service. Some garages offer them as an add-on — worth asking if your car is approaching the mileage interval.

What happens if I skip a full service?

Skipping a service risks undetected issues turning into costly repairs, reduced fuel efficiency, and a gap in your service history that lowers resale value.

Do I really need a full service every year?

Yes — annual services maintain performance, safety, and warranty cover. If you drive fewer miles, an interim service in between may suffice. Find your nearest Point S centre for tailored advice.

How long does a car service take?

An interim service typically takes 1 to 1.5 hours, while a full service takes around 2 to 3 hours. A major service is more comprehensive and can take up to 4 hours. Durations may increase if your mechanic identifies necessary repairs or if you book an MOT simultaneously.

Regular car servicing is the most effective way to ensure your vehicle remains safe, efficient, and reliable on UK roads. By adhering to a consistent service schedule—choosing between interim, full, or major levels based on your mileage—you can identify minor issues before they escalate into expensive repairs. While an MOT is a legal necessity, a professional service provides the preventative maintenance your engine and safety systems require to perform at their best.
