What Is a Gas Safety Certificate (CP12)?
A Gas Safety Certificate, officially known as a CP12, is a document issued by a Gas Safe registered engineer after inspecting and testing all gas appliances and installations in a property. The inspection covers boilers, gas fires, gas cookers, gas hobs, and any other gas-burning appliances, along with the associated pipework and flues. The certificate confirms whether each appliance is safe to use or requires remedial action.

Why You Need a Gas Safety Certificate (CP12)
Under the Gas Safety (Installation and Use) Regulations 1998, landlords are legally required to have all gas appliances, fittings, and flues checked annually by a Gas Safe registered engineer. Failure to comply is a criminal offence that can result in fines, imprisonment, and invalidation of your insurance. Gas leaks and carbon monoxide poisoning from faulty appliances can be fatal — annual inspections are critical for tenant safety.
