Landlord Gas Safety Certificate (CP12) – WLBC Services Ltd
Legal Requirement
Landlord Gas Safety Certificates (CP12)
Annual CP12 gas safety inspections carried out by Gas Safe registered engineers. We work with private landlords, letting agents and property management companies — certificates issued on the same day as the inspection.
The Gas Safety (Installation and Use) Regulations 1998 require all private landlords to have a Gas Safety Record — commonly called a CP12 — carried out annually on every gas appliance in their rental property. This isn't optional, it isn't conditional on the property's age, and it applies to every rental property. Failure to comply can result in unlimited fines, six months imprisonment, and — most seriously — genuine danger to tenants.
If a landlord cannot produce a valid, in-date Gas Safety Record, they face prosecution, an unlimited fine and up to six months in prison. In the event of a gas-related incident at a property without a valid CP12, landlord liability is essentially unlimited. No managing agent or letting agency will manage a property without one — and most mortgage lenders and insurers require annual gas safety certification as a condition of cover.
