How much is a landlord gas safety certificate (CP12)?

From £79.99 for a single-appliance property in our coverage area. Properties with multiple gas appliances (boiler plus gas hob, gas fire, etc.) are quoted on the day. Certificate is issued and emailed on completion.

How long does a CP12 take?

A typical single-boiler CP12 takes 30–45 minutes. Properties with multiple appliances usually take 60–90 minutes.

Can you install a gas cooker?

Yes. We supply and fit, or fit-only, gas hobs, range cookers and freestanding cookers. All work is Gas Safe certified and notified where required.

What should I do if I smell gas?

Call the National Gas Emergency Service immediately on 0800 111 999, open windows, do not turn electrical switches on or off, and evacuate. Once the supply is isolated, call us to investigate, repair and recommission.
