Service History
Quick answer: Service history is the documented record of every scheduled service the car has received during its life: the state of being maintained in line with the manufacturer's schedule. It is distinct from the service book, which is the physical or digital document that evidences it. Under the BVRLA Fair Wear and Tear standard, an incomplete history at lease return can trigger a recharge or a devaluation.
In workshop and fleet language, service history is the track record; the fact of having stuck to the service schedule. Used-car trade shorthand breaks it down into three tiers: FSH (Full Service History (every service done on time, anywhere competent), FDSH (Full Dealer Service History) every service done by franchised dealers), and FMSH (Full Main-dealer Service History, same, sometimes used interchangeably with FDSH). The hierarchy matters because it signals who stamped the book and how much weight the trade puts on it at resale.
What it means
Service history is an evidence trail. It is the sum of every service event carried out at the intervals specified by the manufacturer, usually annually, at a set mileage, or on a condition-based schedule reported by the car itself. Each event is recorded either by a dated stamp and signature in the paper service book or, on most cars from about 2015 onward, as a line in the manufacturer's online digital service record (DSR) keyed to the VIN. A "full" history means no gaps: every due service was carried out within the tolerance window and is evidenced. A "partial" history means one or more services are undocumented, even if the car was driven carefully. The distinction the industry draws is not about how the car has been treated. it is about what can be proved on paper.
Why it matters
Missing stamps cost money in three separate ways, and only the first is obvious. A lease obliges you to service to the manufacturer schedule and produce the evidence, so a gap in the record can trigger either the cost of the missing service or a devaluation reflecting what the car is now worth to remarket. That decision typically gets made at the lease return inspection.
Resale is the second, and it applies whether the car is leased or owned. UK valuation guides treat full history as the baseline assumption, so cars without it sit longer and sell for less, and trade books routinely mark down a valuation where the record is partial.
Warranty is the third and the most easily overlooked. Manufacturer cover explicitly requires servicing to schedule, so a broken history can invalidate a claim on the outgoing car and follow it to whoever buys it next.
Where service history is checked
The phrase appears in lease agreements, hand-back inspection reports, used-car adverts and trade valuations. Typical wording includes "FSH required at return", "one service missing (recharge applied", "FDSH, last stamp 2025", "no service record in vehicle) devaluation per BVRLA standard" or "digital service record not updated". On the forecourt it appears as the abbreviations FSH, FDSH and FMSH directly in the advert copy.
Context
Service history is one half of a pair. The other half is the service book - the physical or digital artefact that evidences it. The history is the underlying state (the car has been maintained); the book is the proof (we can show it). At lease end, both need to line up: the BVRLA standard treats an unstamped book or a missing printed DSR copy the same way as a genuinely missed service. This sits alongside the other documentation the lease agreement demands at hand-back (owner's manual, MOT certificate, radio/security codes and the full set of keys) but service history is the item most commonly flagged because the driver is responsible for keeping it up to date during the lease term.
Common mistakes
- Confusing service history with the service book. The book is the document; the history is the underlying record of events it evidences. A stamped book with a missing service is still "broken" history.
- Assuming a digital service record needs nothing at hand-back. BVRLA guidance requires a printed copy of the electronic service record to be in the car: a clean DSR that nobody printed still counts as missing paperwork.
- Letting a service slip outside the tolerance window late in the lease because "the car's going back anyway". The missed service becomes a recharge or devaluation, almost always larger than the service itself would have cost.
- Using a non-franchised garage without keeping the itemised invoices. Independent servicing can still count as FSH, but only if the paperwork clearly shows each service was to the manufacturer's schedule.
