The Ultimate Car Servicing Guide 2026/27

What a service is - and what it is not

Servicing is preventative maintenance carried out to a schedule. A garage replaces consumables that degrade with time and use - engine oil, filters, sometimes spark plugs and fluids - and inspects the wear items that will eventually need replacing, so problems are found while they are still cheap.

It is not a legal requirement. It is not a roadworthiness test. And it is not a guarantee: a service tells you the condition of the car on the day, in the same way the MOT does.

• Legally optional, but often required to keep a manufacturer warranty or service plan valid
• Protects resale value - a documented history is one of the few things a private buyer can verify
• Finds wear early, when a £40 part prevents a £400 consequence
• Separate from the MOT, though many drivers book MOT and service at the same visit

Interim, full and major services compared

Most independents sell three tiers. Treat the names as marketing labels and the checklists as the real specification.

• Interim service - roughly every 6 months or 6,000 miles. Engine oil and oil filter plus a safety and fluid-level inspection. Aimed at high-mileage drivers between full services.
• Full car service - roughly every 12 months or 12,000 miles. Everything in an interim plus air and pollen filters, a longer inspection list and usually more fluid top-ups.
• Major car service - roughly every 24 months or 24,000 miles. A full service plus longer-interval items such as spark plugs, fuel filter and brake fluid, depending on the schedule.

None of these tiers is standardised. Ask for the checklist in writing and check which filters, which oil specification and which extra items are included before comparing two prices.

How often should you service your car?

Follow whichever comes first - the time interval or the mileage interval in your handbook. Many modern cars use variable or condition-based servicing and calculate the due date from how the car has actually been driven; older cars use fixed intervals.

Driving pattern matters more than most owners assume. Short journeys where the engine never fully warms, heavy towing, sustained stop-start city use and long periods of standing all shorten useful oil life. If that describes your driving, service at the shorter end of the range regardless of what the indicator says.

What is genuinely included - and what is extra

The single biggest cause of quote disputes is scheduled work that owners assume is part of a service and garages price separately. It usually is separate, and legitimately so, because these items are on their own manufacturer intervals.

• Cambelt or timing belt replacement - a separate scheduled job, typically the largest planned bill in a petrol or diesel car's life
• Automatic or DSG transmission oil and filter - separate, on its own interval
• Brake fluid - usually every two years, sometimes bundled into a major service
• Coolant, spark plugs on long-life schedules and diesel particulate filter work - schedule-dependent
• Brake pads, discs, tyres, wipers and bulbs - replaced on condition, never included as standard

What servicing costs in 2026/27

There is no official servicing price index, so the honest answer is that published figures come from commercial providers quoting their own work. Two current, checkable sources:

RAC's car service pricing page currently states an average quoted full service of £298.60, with make-level examples including Ford £277.32, Vauxhall £284.50, Volkswagen £280.33, Nissan £280.88, Peugeot £287.80, Audi £296.95, BMW £316.10 and Mercedes-Benz £319.02. Those are RAC quoted-price figures, not a universal market average.

The AA advertises servicing from £146 for an interim, £187 for a full and £227 for a major service, and states that at least 10% of UK Mobile Mechanics customers paid that price or less for the specific service between 1 April and 31 May 2026. Advertised "from" prices are entry points, not typical prices.

Figures quoted from third parties are that organisation's own published or advertised prices on the date we checked them, not a UK market average and not a price any garage on Serviced247 is offering. Always get an itemised quote before booking.

Franchised dealer or independent garage?

UK motor-vehicle competition rules are designed to keep aftermarket servicing and repair open to independent garages, including access to parts and technical information. They do not override your warranty terms: a manufacturer warranty is a contract, so you still need the manufacturer's schedule followed, correct-specification oil and parts used, and the work properly evidenced. Read the maintenance conditions in your own warranty or service plan before booking, and keep itemised invoices as well as stamps. Franchised dealers still hold advantages for software updates, recalls and model-specific diagnostics.

The practical decision usually comes down to warranty status, the complexity of the car and whether your local independent has the right equipment and data access for your make.

How to compare quotes properly

• Ask for the checklist and the oil specification in writing, not the tier name
• Confirm whether parts are OE, OE-equivalent or budget, and what parts warranty applies
• Check whether the quote includes VAT, sundries, disposal and any diagnostic charge
• Ask which longer-interval items fall due on this visit and price them separately
• Require that any additional work is authorised by you before it starts
• Confirm the service will be recorded in the service book or digital service record

Citizens Advice publishes guidance on finding an approved garage and on your rights if work is not carried out with reasonable care and skill.

Where to go next

If you are pricing a job, our car service cost guide breaks the numbers down by tier. If your MOT is due at the same time, the MOT and service guide explains how combining them actually works. Electric owners should start with electric car servicing, because the conventional tiers barely apply.
