Gas Service & Maintenance Record

A Gas Service & Maintenance Record documents the annual service of a single gas appliance such as a boiler, fire, or cooker. It covers the FAGS checks (Flue, Air supply, Gas rate, Safety devices) and combustion analysis in accordance with BS 7967. Unlike a CP12, which covers all appliances at a property for landlords, a service record covers one appliance for any customer.

GSIUR 1998 Regulation 26(9), BS 7967 Combustion AnalysisValid: Annual (12 months)

Frequently asked questions about Gas Service Record

Is a gas service record the same as a CP12?
No. A CP12 is a landlord gas safety check covering all appliances at a rental property. A service record covers a single appliance in any property. Homeowners need service records; landlords need CP12s.
Do I need a gas service for my boiler warranty?
Almost certainly yes. Every major boiler manufacturer (Worcester Bosch, Vaillant, Baxi, Ideal) requires annual servicing by a Gas Safe engineer to maintain the warranty. Keep your service record as proof.
What does a gas service include?
A full service includes visual inspection, component checks, gas tightness test, pressure measurements, flue checks, and combustion analysis using a flue gas analyser. The engineer records all readings on the service record.
