Why a “Full Service History” Doesn’t Always Mean What You Think

But here’s the truth most people won’t tell you: a "Full Service History" isn’t always what it seems.

Let’s break it down. Because understanding what you’re really getting can save you a lot of cash and stress later on.

What Is a Full Service History (FSH)?

A Full Service History means the car has been serviced on time, every time, throughout its life. Ideally, this includes all the routine maintenance work recommended by the manufacturer.

You might see these other terms too:

• Partial Service History (PSH): Only some services are recorded

• Main Dealer History: All services done at official dealerships

• Independent Service History: Services completed at third-party garages

On paper, a full service history is a good thing. It can:

• Boost resale value

• Show consistent care

• Give peace of mind that the car has been looked after

But here's the problem: there's no universal rule for what counts as "full". Some sellers stretch the truth. Some misunderstand it. Some flat-out lie.

FSH Doesn’t Mean Flawless

Just because a car has a stack of service stamps doesn’t mean it’s mechanically perfect. Why?

• Some garages only tick boxes: They might skip work or use low-quality parts

• Service intervals might be too far apart: Missed oil changes or long gaps can cause engine wear

• Stamped books can be forged: Yes, people fake them

• Important repairs might be missing: Services don’t always cover major faults

Basically, you need to look deeper than the stamp.

How Sellers Stretch the Truth

Sellers know that "FSH" adds value. So they sometimes get creative with the term.

• They might count just one previous service as "full"

• They might include services with missing receipts

• They might call a few oil changes over 10 years a "full history"

That’s why it’s crucial to always ask for proof. Don’t just take their word for it.

What to Look for in a Genuine FSH

Here’s how you can tell if the service history is legit:

1. Receipts and Invoices

Ask for itemised receipts, not just stamps in a booklet. Real invoices show:

• What was done

• When

• By whom

• What parts were used

2. Consistency

Was the car serviced at regular intervals? For most cars, that’s every 10,000 to 15,000 miles or once a year. Look for:

• Matching mileage and dates

• No suspicious gaps

• Same or trusted garages

3. Big Ticket Items

A full service history should include:

• Timing belt changes (usually between 60k - 100k miles)

• Brake pad and disc replacements

• Clutch changes (for manual cars)

• Suspension work

4. Garage Reputation

Look up the garages mentioned in the records. Are they legit? Well-reviewed? Still operating?

The Fake FSH Problem

Unfortunately, forging service histories isn’t rare. In fact, it’s one of the oldest tricks in the book.

How it happens:

• Buying fake stamp kits online

• DIY-stamping a blank service book

• Faking receipts with editing software

That’s why relying on paperwork alone can be risky. Combine it with other checks.

What a Vehicle History Check Can Reveal

A good car history check (like the ones at TopCarCheck.co.uk) won’t show service records directly, but it will give you vital context:

• Mileage history from MOTs

• Gaps that hint at missed servicing

• Ownership changes

• MOT failures (which may indicate poor maintenance)

• Insurance write-offs or accident flags

Pairing this with the car's paperwork gives you a much clearer picture.

Why It Matters

Skipping out on proper servicing can lead to big issues:

• Worn-out engines

• Transmission problems

• Faulty brakes

• Sludge buildup from old oil

• Broken timing belts (can destroy engines)

These are all expensive to fix. A fake or flimsy service history might mean you’re buying a car with hidden damage or neglect.

How to Protect Yourself

Before buying a used car, here’s a checklist:

• Ask for all service records

• Cross-check with MOT history (use Gov.uk MOT checker)

• Run a car history check at TopCarCheck.co.uk

• Look for signs of clocking (mileage rollback)

• Be cautious if the seller is pushy or vague

• If in doubt, get a pre-purchase inspection from a mechanic

Real-World Example: Jess’s Close Call

Jess found a lovely-looking Audi A3 listed with "Full Service History". The seller even had a stamped book. But when she asked for receipts, there were none. A quick MOT check showed mileage gaps. A TopCarCheck search revealed it was a Cat N write-off with three previous owners in one year.

She walked away - and found a better car a week later.

Bottom Line: Don’t Be Blinded by the Stamp

A full service history sounds great. And sometimes, it really does mean the car’s been looked after. But don’t take those three words at face value.

Dig deeper. Ask for evidence. Cross-check everything. Because a well-maintained car is worth paying for - but a dodgy one with a fake history? That’s just a headache waiting to happen.
