Interim service vs full service: which do you need?
Updated 2 min readSources: The Motor Ombudsman
Quick answer
A full (or major) service is a broader inspection than an interim (or minor) service, which is meant for the gap between full services. The names are not standardised, so compare what each garage actually includes. Your manufacturer's schedule tells you what is due and when.

- Fewer checks, between full services

The difference in plain terms
- Interim (minor) service
- A shorter service meant for between full services. The checks are usually more limited, typically the basics such as oil and filter, fluid levels and a look at safety items like tyres and brakes.
- Full (major) service
- A broader examination of the vehicle than an interim service. What it includes depends on your car's age, mileage and manufacturer's schedule, and it may add parts that fall due at longer intervals.
Warning: There is no single definition. The names used for annual service levels vary between garages and manufacturers, and a full service at one garage may include more or less than at another.
Which one do you need?
Follow your car's schedule. It is in the owner's manual, the service book or the digital service record, and newer cars may tell you on the dashboard when a service is due. Intervals are set by the manufacturer, usually by time, mileage or whichever comes first.
If you cover a high mileage, an interim service between full services can catch wear earlier. That is your choice, not a legal requirement. See how often to service your car.
Compare quotes by what is included, not the name
- Ask for a written quote that explains the level of service and lists the checks included.
- Ask whether top-ups, replacement parts and disposal charges are included in the price.
- Confirm the garage will ask for your authorisation before doing any extra work.
Keep the service history
A complete service record helps when you sell the car, because buyers look at it. For a car under warranty it may also be a condition of claims. Keep invoices and make sure stamps or digital records are kept up to date.
A service is not an MOT. They are separate, and passing one says nothing about the other: see what an MOT checks.
Common questions
Is an interim service enough on its own?
It can be, if it fits your manufacturer's schedule. It is not a substitute for the full service when one is due.
Does a service include an MOT?
No. They are separate. A garage may offer both together, so check what the quote covers.
Is a service a legal requirement?
No, unlike the MOT. But your vehicle must be roadworthy at all times, and warranty terms often require servicing at the recommended intervals.
Why do two garages quote different prices for a full service?
Because what a full service includes varies. Ask each garage for the list of checks and whether parts, top-ups and disposal are included, then compare like with like.
