How to Check a Car's Service History — Complete UK Guide

Summary

• Check the service book: Look for dated stamps from garages or dealers matching regular intervals.
• Ask for invoices: Receipts from garages prove what work was done and when.
• Check online dealer records: Many manufacturers keep digital service records you can access online.
• Use a vehicle history check: A car history check can reveal MOT history, mileage records, and more.

A car's service history tells you how well it has been looked after. It can reveal whether the previous owner kept up with regular maintenance — or let things slide.

Whether you are buying a used car or checking your own records, this guide shows you exactly how to check and verify a car's service history.

Why Service History Matters

Service history matters for three big reasons:

• Value: A full service history (FSH) can add 10-20% to a car's resale value. Buyers pay more for a car they know has been maintained.
• Reliability: A car with regular services is far less likely to have hidden problems. Missed services often lead to expensive breakdowns.
• Warranty: Many manufacturer warranties require servicing at set intervals. Missing a service could void the warranty. Read our car warranty guide for more.

Did you know? According to Auto Trader, cars with a full service history sell for an average of £1,000-£2,000 more than the same car without one.

Check the Service Book

The first place to look is the car's physical service book. This is usually a small booklet that came with the car when it was new. It lives in the glove box or with the owner's handbook.

Each time the car is serviced, the garage or dealer should stamp the book. A good service book shows:

• The date of each service
• The mileage at each service
• The name and stamp of the garage or dealer
• What type of service was done (interim, full, or major)

What to Look For

Check that services happened at regular intervals — usually every 12 months or 10,000-12,000 miles. Look out for:

• Gaps: Missing stamps or long gaps between services are a red flag.
• Mileage jumps: If the mileage between services does not match normal use, the odometer may have been tampered with.
• Handwriting changes: If the stamps look different or inconsistent, they may not be genuine.

Ask for Invoices and Receipts

Service stamps alone do not tell the full story. Invoices and receipts show exactly what work was done, what parts were used, and how much it cost.

If you are buying a used car, ask the seller for:

1. All service invoices and receipts
2. MOT certificates (especially if showing advisories)
3. Receipts for any repairs or part replacements
4. Tyre change receipts

A seller who has kept all their paperwork is usually a seller who has looked after the car. If they cannot provide any records, that is a warning sign.

Check Online Manufacturer Records

Many car manufacturers now keep digital service records. If the car was serviced at an authorised dealer, the records are often available online.

Here is how to check some of the most popular brands:

Brand	How to Check
BMW	Contact any BMW dealer with the VIN number
Volkswagen	VW Digital Service Schedule — any VW dealer can check
Ford	Ford Etis system — dealers can access online
Mercedes	Mercedes me portal or any dealer
Audi	Audi Service History Online — through any Audi dealer
Toyota	MyToyota app or any Toyota dealer
Vauxhall	Contact any Vauxhall dealer with the VIN

Even if the car was not serviced at a dealer, many independent garages now use digital platforms like Autodata or BookMyGarage to log service records. Ask the garage if they can provide a digital record.

Check the MOT History

MOT records are one of the best ways to verify a car's history. They are completely free to check and go back years.

An MOT record shows:

• The mileage at each test — so you can spot any suspicious jumps or reductions
• Pass/fail results
• Advisories — these tell you what might need attention soon
• Failure reasons — what needed fixing

Use our free MOT history check tool to look up any car's MOT history using its registration number. You can also check directly on the gov.uk MOT check website.

Read our guide to reading MOT history for help understanding what the results mean.

Use a Car History Check

A full vehicle history check gives you even more detail than the service book and MOT records alone. It can reveal:

• Outstanding finance: Is the car still being paid for? If so, you could lose it.
• Write-off history: Has the car been written off by an insurer?
• Stolen status: Is the car on the police stolen vehicle register?
• Mileage discrepancies: Does the mileage match across MOT tests, service records, and DVLA data?
• Plate changes: Has the registration been changed (sometimes used to hide a car's past)?
• Number of previous owners: More owners in a short time can be a warning sign.

Run a full car history check before buying any used car. It takes minutes and could save you thousands. Read our car history check guide for more details.

Red Flags to Watch For

When checking service history, these are the warning signs that something might not be right:

1. No service book at all: It might have been lost — or there may be no services to record.
2. Long gaps between services: Anything over 18 months between services is concerning.
3. Mileage does not add up: Compare the mileage in the service book with MOT records. The numbers should match roughly.
4. Services done at random garages: Not a problem on its own, but combined with other red flags, it can suggest the history is not genuine.
5. Fake stamps: Look for stamped signatures, official garage details, and consistent ink. If the stamps look photocopied or hand-drawn, be wary.

If something does not feel right, walk away. There are plenty of well-maintained cars for sale. See our red flags when buying a used car guide for more.

How to Build Your Own Service History

If you already own a car and want to build up a strong service record, here is what to do:

• Get the car serviced on time, every time. Follow the manufacturer's recommended intervals.
• Keep all invoices and receipts in a folder.
• Ask the garage to stamp the service book at every visit.
• Save digital copies of invoices in case the paper ones get lost.
• Use an independent garage if the dealer is too expensive — just make sure they use the right parts and log the service properly.

A full service history makes your car worth more when you sell. Read our guide to getting the best price for your car for more tips.

Quick Service History Checklist

Use this checklist when checking any car's service history:

1. Is there a physical service book with regular stamps?
2. Do the mileage entries increase consistently?
3. Are there invoices or receipts to back up the stamps?
4. Does the MOT mileage match the service book? (Check with our free MOT check)
5. Are there any suspicious gaps or mileage drops?
6. Has a full history check confirmed no hidden issues?

Taking 10 minutes to check these things could save you from buying a problem car — and thousands of pounds in unexpected repairs.
