Confused about interim vs full service? Learn what’s included, key differences, costs, and when to book. Plus, set reminders with the esure app.
An interim service is a lighter, more frequent check covering essentials like oil, filters, brakes and tyres, typically every 6 months or 6,000 miles. A full service is a more thorough annual check covering up to 80 components. They work together, so it’s important to note that an interim does not replace a full service.
What is an interim service?
Think of an interim service as your car's regular health check. It's designed to keep your vehicle running safely between full services, focusing on the parts that wear down most quickly through everyday use. Although an interim service may be required on some vehicles, all cars should get a full service every 12 months or 12,000 miles, regardless of whether they have had an interim service or not.
An interim service can be useful if you drive more than the UK average of around 7,400 miles a year, or if you do a lot of short journeys, which can cause engine oil to degrade faster because it never fully warms up. If your car is making a weird noise or consumes fuel too quickly, these might be signs you need to book an interim service.
What is included in an interim vs a full service?
While every garage is different, most interim and full services follow a broadly similar structure, covering key areas of your car from the engine and brakes through to tyres, lights, and fluid levels. The exact number of checks and whether certain items are inspected or replaced can vary depending on where you book and your car's make, model, and age. It's always worth confirming what's included with your garage before you go. As a general rule, an interim service includes up to 35 checks while a full service includes up to 80 checks.
See some of the main differences between the two services below.
| Check | Interim | Full Service |
|---|---|---|
| How often | Every 6 months / 6,000 miles | Every 12 months / 12,000 miles |
| Typical Time | 1.5 - 2 hours | 3 hours |
| Number Of Checks | c.35 checks | c.80 checks |
| Oil & Filter Change | Yes | Yes |
| Air Filter Change | No | Yes |
| Full Fluid Top-ups | Partial | Full |
| Drive Belt Inspection | No | Yes |
| Service Book Stamp | Yes | Yes |
| Best For | High-mileage drivers | Required for all drivers once a year |
Common myths about car servicing
There's a lot of confusion around servicing, especially when it comes to what each type actually covers. Here are a few things worth clearing up.
MYTH - “An interim service replaces a full service”
~ An interim service is designed to sit between full services, not replace them. It covers fewer components, so a full service is still needed every year.
MYTH - “A service is the same as an MOT”
~ They're very different. An MOT is a legal requirement that checks your car meets minimum safety and emissions standards. A service focuses on maintenance and catching problems early; it's not a legal requirement but strongly recommended.
MYTH - “If I don’t drive much, I don't need an interim service”
~ Low mileage isn't always the deciding factor. Lots of short, stop-start journeys can be just as hard on your engine as high mileage, as the oil never fully heats up, which means it degrades faster.
TRUTH - “A full service includes everything in an interim service and more”
~ An interim service includes top-level checks, which are a core part of both. Where they differ is in the scope and depth of everything else that's covered by a full service.
Interim or full service: which do you need?
Knowing which type of service your car needs can be challenging, and you don’t want to be overpaying for a service you don’t need. Below is a simple guide to help you decide if you need a full service or an interim service.
| Book an interim service if… | Book a full service if… |
|---|---|
| - It's been around 6 months since your last full service | - It's been 12 months or 12,000 miles since your last service |
| - You're covering significantly more than 7,400 miles a year | - You're planning a long trip or holiday |
| - You do a lot of short journeys in stop-start traffic | - You're buying or selling a car (service history matters) |
| - You want peace of mind between annual services | - Your car is due for its annual MOT (often booked together) |
| - Your car is making unusual noises or handling differently | - You haven't had any service done in the last year |
The benefits of keeping on top of your car's servicing
Servicing might feel like another thing on the to-do list, but staying on top of it can save you a lot of hassle and money down the line.
- Fewer Breakdowns: Regular servicing spots problems before they become costly failures, keeping you moving safely.
- Lower Costs Long Term: Fixing small issues early is far cheaper than dealing with major faults that develop through neglect.
- Better Fuel Efficiency: Fresh oil and clean filters help your engine run more efficiently, which can potentially reduce fuel consumption.
- Stronger Resale Value: A full service history reassures buyers and can add meaningful value when you come to sell.
- Safer Driving: Brakes, tyres and lights are all checked as part of both services, the things that matter most on the road.
