What is a Service History Check? Complete Guide 2025

What is a Service History Check?

A service history check is a detailed report that reveals the complete maintenance and servicing record of a vehicle throughout its lifetime. It shows when and where the car was serviced, what work was performed, and whether it has been maintained according to the manufacturer's recommended schedule.

In the UK, service history checks typically access digital records from authorised dealerships and garages that are connected to manufacturer databases. This provides an official, verified record of all maintenance work performed on the vehicle.

Why is Service History Important?

A full service history is one of the most valuable pieces of information when evaluating a used car. Here's why it matters:

1. Verification of Regular Maintenance

Regular servicing is essential for vehicle longevity and performance. A complete service history proves the car has been properly maintained according to manufacturer guidelines, reducing the risk of hidden mechanical problems.

2. Identifying Potential Issues

Service records can reveal recurring problems or major repairs that may indicate underlying issues. For example, frequent brake replacements or repeated engine work could signal problems the seller hasn't disclosed.

3. Validates Mileage Claims

Service records include mileage readings at each service interval, making it easy to verify whether the odometer has been tampered with (also known as "clocking"). Any inconsistencies in mileage progression are red flags.

4. Affects Resale Value

Cars with full service history (FSH) command significantly higher resale values - typically 10-20% more than vehicles without documented service records. Buyers are willing to pay more for the peace of mind that comes with verified maintenance.

5. Warranty Requirements

Many manufacturer warranties and extended warranty policies require proof of regular servicing. Without a documented service history, your warranty claims may be denied.

What Information is Included in a Service History Check?

A comprehensive service history report typically includes:

• Service dates and intervals - When each service was performed
• Mileage at each service - Odometer readings to verify accuracy
• Work performed - Detailed list of maintenance tasks and repairs
• Parts replaced - Which components were changed (oil filters, brake pads, etc.)
• Servicing location - Which garage or dealership performed the work

Types of Service History

Full Service History (FSH)

A full service history means the vehicle has been serviced at every interval recommended by the manufacturer, with complete documentation of all work performed. This is the gold standard and significantly increases the car's value.

Partial Service History

A partial service history means some services are documented but there are gaps in the record. This could indicate missed services or work performed at independent garages that don't report to manufacturer databases.

No Service History

No documented service history is a major red flag. While the car may have been serviced, there's no way to verify it. This significantly reduces the vehicle's value and increases the risk for buyers.

Digital vs. Paper Service Books

Modern vehicles increasingly use digital service history stored in manufacturer databases, replacing traditional paper service books. Digital records are more reliable, can't be lost or forged, and are easier to access through official checks.

How to Check a Vehicle's Service History

There are several ways to verify a car's service history in the UK:

1. Manufacturer Database Checks

The most reliable method is accessing official manufacturer databases. Services like CheckThisReg retrieve service records directly from BMW, Mercedes-Benz, Audi, Volkswagen, Land Rover, and other premium manufacturers.

2. Physical Service Book

Older vehicles may have a physical service book with dealer stamps. While useful, paper books can be lost, damaged, or even forged. Always verify stamps with the listed garages if possible.

3. Dealership Inquiry

You can contact the vehicle's manufacturer dealership directly and request service history, though this process can be time-consuming and may not provide complete records if the car was serviced at multiple locations.

4. MOT History

While not a service history, MOT records (available free on gov.uk) show annual mileage readings and can help identify odometer discrepancies or major defects noted during tests.

Red Flags in Service History

Watch out for these warning signs when reviewing a vehicle's service records:

• Gaps in servicing - Long periods between services suggest neglect
• Mileage discrepancies - Odometer readings that don't make sense chronologically
• Major repairs - Extensive engine or transmission work could indicate serious issues
• Missing recent services - If the car is due for service now, the seller may be hiding problems
• Generic servicing - Non-manufacturer approved garages may use inferior parts

Frequently Asked Questions

Can I get service history with just a registration number?

Yes! With a UK registration number, you can access a vehicle's complete service history from manufacturer databases. This is the quickest and easiest method.

What if the car has no service history?

A car without service history should be approached with caution. You'll need to budget for a comprehensive inspection by a qualified mechanic and should factor in a significant price reduction (typically 10-20% below market value).

Do independent garage services count?

Yes, but they may not appear in manufacturer databases. Independent garage services are valid if properly documented, though manufacturer-approved servicing is preferred for warranty purposes and typically uses genuine parts.

How far back does service history go?

Digital service history typically covers the entire vehicle lifetime from when the manufacturer implemented digital record-keeping. For premium brands like BMW and Mercedes, this can be 10-15+ years of complete records.

Conclusion

A service history check is essential due diligence when buying any used vehicle. It provides invaluable insight into how the car has been maintained, helps verify mileage accuracy, and can save you thousands of pounds by identifying problems before you buy.

For the most reliable and comprehensive service history information, always use official manufacturer database checks rather than relying solely on paper service books or seller claims.
