What Is a Logbook? Every Type of UK Logbook Explained (2026)
In UK English, 'logbook' covers everything from the V5C vehicle registration to pilot, sailor, HGV driver, nurse and security records. The full taxonomy explained.
Quick answer: In UK English, "logbook" covers at least 13 distinct categories. In motoring, it's the V5C vehicle registration certificate. In aviation, it's a pilot's flight record. In marine, a ship's or yacht's voyage record. In healthcare, a professional's CPD or revalidation portfolio. The term spread from "ship's log" (the original meaning) to any official record of activity, ownership, or compliance. This page is a UK disambiguation guide: skim the categories below and click through to the specific logbook you need.
The original meaning
"Logbook" comes from the maritime "ship's log" — originally a wooden board ("log") thrown overboard to measure a ship's speed by the rate at which a rope unspooled. The record-keeper noted speed, position, and conditions. The word transferred to the bound book itself, then to any official record of activity.
Today in the UK, "logbook" applies to dozens of separate documents, each with its own legal framework. This is the disambiguation page.
Vehicle and V5C Logbooks
Most common UK use of "logbook" = the V5C vehicle registration certificate. It records the registered keeper of a UK vehicle and the vehicle's specifications. Issued and managed by DVLA.

Aviation Logbooks
A pilot's flight logbook records every flight, including aircraft type, route, hours, take-offs, landings, and special conditions. Required for CAA, EASA, and most other regulators. Mandatory for licence revalidation and ATPL progression.
Marine Logbooks
Used by sailors, ship's masters, and yacht skippers to record voyages, sea miles, weather, and crew. The RYA personal logbook tracks miles and qualifying passages for Yachtmaster certification. The MCA ship's logbook is required on commercial vessels.

FAQs
Are all these "logbooks" legally required?
Most are. The V5C (Vehicle Excise and Registration Act 1994), HGV records (EU 561/2006), HACCP (Regulation 852/2004), fire safety (RRO 2005), etc. are statutory. A few — like classic car provenance files — are voluntary but commercially essential.
Can one "logbook" serve multiple regulatory purposes?
Rarely. Most have specific format and retention rules. The MCS solar certificate is different from the EICR which is different from the Gas Safety Record. Treat each as a separate document.
Are digital logbooks acceptable to UK regulators?
Yes, in almost every category — provided they meet the specific requirements for that document type. Some legacy paper forms (V5C, race car logbook) remain physical-only.
How long should each logbook be kept?
Varies. V5C — life of ownership. HGV tachograph — 12 months minimum (Working Time records 2 years). HACCP — typically 12 months past shelf-life. Healthcare CPD — 5 years minimum. Always check the specific regulation.
