What is a major service?
A major service (also known as a full service) is the most in-depth scheduled car maintenance option, designed to keep your vehicle running smoothly and safely for the long term.
It replaces more wear-and-tear parts than interim/minor or standard services and carries out deeper checks that help prevent costly repairs later on.
Servicing isn’t a legal requirement in the UK like an MOT is, but it’s still recommended to keep your car safe and roadworthy.

What’s included, how much is it and why’s it important?
A major service includes changing key fluids and maintenance components, and a range of mechanical checks. It’s important because it helps maintain engine health, protects key mechanical systems and supports your car’s long‑term reliability.
Regular major servicing also helps preserve resale value and reduces the risk of breakdowns.
So, your car should run better for longer and might even sell for more when it’s time to move on.
What’s included in a major car service?
A typical major service covers an extensive list of maintenance tasks. These usually include:
Oil and filter change - keeps the engine lubricated
Brake fluid change - ensures a safe and responsive braking system
Air and fuel filter replacement - helps the engine breathe clean air and receive clean fuel
Full inspection of brakes, suspension and steering - checks for wear, safety issues and performance
Diagnostic checks - scans the car’s onboard systems for faults or error codes
Spark plugs – may also be replaced during a major service, depending on the garage and mileage intervals
When should you book a major service?
Most manufacturers recommend a major service every 24 months or 24,000 miles, whichever comes first. Your car’s handbook will confirm the exact interval.
Sticking to these guidelines keeps the car in good mechanical condition and reduces the likelihood of unexpected repair bills.
If your car is within warranty, you’ll need to stick to the servicing schedule to make sure the warranty is valid. You might also be required to go to a ‘main dealer’ garage for your servicing.

Engine oil and filter change
Brake fluid replacement
Air filter and fuel filter replacement
Spark plugs (if applicable, not always included)
Brake, suspension and steering inspection
Full diagnostic scan

How long does a major service take?
A major service usually takes between two and four hours, depending on the car and the number of parts that need replacing.
How does a major service differ from a full service?
The name of each car service can differ between garages, but generally, a major service and a full service are the same thing.
They both go further than minor/interim services and standard services, replacing more maintenance components and carrying out deeper inspections.
A major/full service is recommended every 24 months/24,000 miles, and cost more than minor or standard services due to the extra parts and labour involved.

Major service FAQs
Do I really need a major service?
Yes. While it’s not a legal requirement, major services help keep your car safe, efficient and reliable. Skipping it can lead to increased wear, reduced performance and potentially expensive repairs later. Skipping a service can also invalidate your warranty – so check what’s required of you before making any decisions.
Can I get an interim or full service instead?
You can, but they don’t replace the need for a major service. Interim and full services cover routine maintenance, while a major service includes additional scheduled replacements that protect long‑term engine and system health. Like we mentioned above, check what your warranty requires before making any decisions.
Why does a major service cost more?
A major service costs more as it includes more labour and more replacement parts, such as spark plugs, brake fluid and additional filters.
