Landlords letting residential properties in England must obtain an annual Gas Safety Certificate (CP12) from a Gas Safe registered engineer for every gas appliance, flue and pipework on the property. We carry out same-day CP12 inspection and certification across London and bundle with EICR + EPC to save 10%.

Frequently asked questions
How often is a CP12 required?
Annually for every let property in England. The certificate is valid for 12 months from the test date. Landlords must give tenants a copy within 28 days of the test (or on tenancy start for new tenants).
What if my boiler fails the CP12?
Gas Safe engineers must classify failures as ID (Immediately Dangerous — disconnected on the spot), AR (At Risk — disconnected with permission) or NCS (Not to Current Standards — left in service with advice). We'll talk you through whatever we find before disconnecting anything.
Can you do EICR and CP12 in the same visit?
Yes — bundling EICR and CP12 saves 10% across both certificates and one tenant disruption. Same-day digital certificates for both.
