The service book that can’t be lost or faked.

Every stamp is immutable, hash-chained to your vehicle, and verifiable by anyone with the QR code. Paper books burn. Service Books don’t.

How it works

01
The workshop stamps it

A verified workshop records the job — work items, parts, mileage — and the stamp is sealed into the vehicle’s hash chain the moment it’s issued. It can never be edited or deleted.

02
The owner carries it

Your whole garage in your pocket, free forever. Timeline, MOT and tax status, reminders — and the book transfers to the buyer when you sell.

03
Anyone verifies it

One QR code shows the full history to a buyer, and every stamp can be independently re-checked against the chain. No account needed. Trust, not claims.

MOT, tax & mileage — woven in

DVLA and MOT data sit in the same timeline as the stamps: every test, every advisory, tax status at a glance — and mileage cross-checked between stamps and MOT readings, so a clocked odometer has nowhere to hide.

Honesty is structural: corrections stay struck-through in the open, and stamps written by the keeper’s own workshop are flagged — the record always says who’s vouching for it.

Every entry says who’s vouching for it

History is only worth what its source is worth. Service Book never blurs the line.

✓ VERIFIED

Issued by a workshop we’ve verified — Companies House, VAT and premises checked. The workshop’s identity is frozen into the stamp forever. If it’s the keeper’s own workshop, the stamp says so.

SELF-RECORDED

Recorded by the owner. Great for DIY oil changes and receipts — always clearly marked, never dressed up as a workshop stamp.

FROM PAPER

Migrated from a paper book with photographic evidence. Better than nothing, honest about what it is.
