Car Maintenance Costs UK 2026/27

A realistic annual maintenance budget, built from the costs that are fixed by law, the ones that are published by providers, and the ones nobody can quote until they look at your car.

Running costs are easy to underestimate because they arrive unevenly. Two quiet years are followed by a cambelt, a set of tyres and a pair of discs in the same quarter. The fix is not to spend less, it is to know which costs are predictable and put money aside for them.

This guide splits UK maintenance spending into what is capped by statute, what providers publish, and what genuinely cannot be quoted until someone looks at the car - with sources for every figure we state.

Key takeaways

  • Only one maintenance cost is fixed by law: the MOT test fee, capped at £54.85 for a Class 4 car.
  • Everything else is a market price - published averages come from commercial providers pricing their own work.
  • Budget in three buckets: statutory, scheduled and wear-and-tear.
  • The big scheduled jobs - cambelt, brake fluid, transmission oil - are predictable years in advance if you read the schedule.
  • Deferred maintenance is usually the most expensive option available.

1. Statutory costs

The MOT is the only maintenance cost with a legal ceiling. GOV.UK caps the Class 4 car test at £54.85 and the Class 7 van test at £58.60. Retests may be free, partially charged or full-price depending on the route taken - see the retest rules.

Vehicle tax and insurance are separate from maintenance, but they belong in the same annual planning exercise because they arrive on fixed dates.

2. Scheduled servicing

Servicing is unregulated and there is no official average. The checkable published figures currently available: RAC states an average quoted full service of £298.60, and the AA advertises interim servicing from £146, full from £187 and major from £227, with the qualification that at least 10% of its UK Mobile Mechanics customers paid that price or less between 1 April and 31 May 2026.

Beyond the annual service, the manufacturer schedule contains a handful of much larger jobs. Read the schedule once and you can see them coming years out.

  • Cambelt or timing belt with water pump - typically the largest planned bill on a belt-driven engine
  • Brake fluid - usually a two-year interval
  • Automatic or DSG transmission oil and filter - mileage-based, model-specific
  • Spark plugs, fuel filter and coolant - schedule-dependent
  • Air conditioning service - not a legal or MOT item, but performance degrades over time

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.

3. Wear and tear

These are the costs nobody can quote in advance because they depend on how, where and how much you drive. Tyres, brake pads and discs, wiper blades, bulbs, batteries, exhaust components and suspension parts all wear at rates set by your driving and your roads.

The useful discipline is to track them. If your MOT advisories mentioned brake pads at 3mm last year, that is next year's bill telling you about itself in advance.

Electric and hybrid maintenance

Battery-electric cars remove oil, filters, plugs, cambelts and exhaust systems from the schedule entirely, and regenerative braking substantially reduces friction-brake wear. They do not remove tyres, brake fluid, cabin filters, suspension or the MOT - and heavier kerb weights on larger wheels can make tyres a bigger annual line than in an equivalent petrol car. Electric car servicing covers the detail.

Building an annual budget

  • Start with the MOT at the statutory cap and your service tier from the manufacturer schedule
  • Add a twelfth of any big scheduled job that is due within the next two or three years
  • Add a tyre sinking fund based on your annual mileage and current tread
  • Carry over last year's MOT advisories as this year's likely spend
  • Keep a contingency: unscheduled repairs are a when, not an if

Controlling costs without cutting corners

  • Book the MOT early in the one-month window so a failure does not force a rushed repair
  • Ask for quotes itemised into legally-required and advisory work
  • Get a second quote on anything over a few hundred pounds
  • Combine an MOT and service into one visit where the dates line up
  • Do the free things: correct tyre pressures, working bulbs, topped-up washer fluid
