How it works
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.
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.
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.
Every entry says who’s vouching for it
History is only worth what its source is worth. Service Book never blurs the line.
Issued by a workshop we’ve verified — Companies House, VAT and premises checked. The workshop’s identity is frozen into the stamp forever.
Recorded by the owner. Great for DIY oil changes and receipts — always clearly marked, never dressed up as a workshop stamp.
Migrated from a paper book with photographic evidence. Better than nothing, honest about what it is.
