Which Car Service Do I Need? Interim vs Full vs Major Explained
There are different levels of car servicing, each designed to check and maintain important parts of your vehicle.
Getting your car serviced regularly helps to:
Spot potential issues before they worsen
Prolong the life of your vehicle
Maintain performance and efficiency
Protect resale value by showing a strong service history
But which service is right for you?
What Is a Major Service?
A major service is the most comprehensive level of routine servicing.
It includes a 45-point inspection, including:
Brake fluid check
Renew engine oil
Renew oil filter
Renew air filter
Renew pollen filter
Recommended interval: Every 24 months or 24,000 miles — whichever comes sooner.
A major service is typically recommended every two years to provide a deeper check of your vehicle’s systems.
What Is a Full Service?
A full service sits between an interim and major service.
It includes a 42-point inspection, including:
Renew engine oil
Renew oil filter
Renew air filter
Recommended interval: Every 12 months or 12,000 miles, in between major services.
This is the most common annual service for many UK drivers.
What Is an Interim Service?
An interim service is designed for drivers who cover higher mileage or want more frequent checks.
It includes a 39-point inspection, including:
Renew engine oil
Renew oil filter
If you drive a lot of miles, an interim service is recommended every 6 months in addition to your annual servicing.
Engine Oil and Oil Filter Change
You could also consider an additional engine oil and oil filter change between services.
Fresh oil helps your engine run smoothly and can contribute to longer engine life, particularly if you regularly drive short journeys or high annual mileage.
How Often Should You Service Your Car?
As a general rule in the UK:
Every 12 months – At least a full service
Every 24 months – Major service
Every 6 months – Interim service (if high mileage)
Always follow your manufacturer’s guidance if it differs.
Quick Answers
What’s the difference between interim, full and major service?
An interim service is a lighter inspection, a full service is an annual comprehensive check, and a major service includes additional component replacements and is usually done every two years.
Is a major service worth it?
Yes. It provides deeper checks and additional replacements that help prevent longer-term issues.
Can I skip a full service?
Skipping servicing can increase wear, reduce resale value and make problems harder to detect early.
