Landlord gas safety certificate (CP12) in London
Landlords must have each gas appliance and flue they supply checked annually by a Gas Safe registered engineer and give tenants the record within 28 days. We handle the visit, the certificate, and — with LandlordPro — the renewal reminder before it ever lapses.
If you smell gas, or a carbon monoxide alarm sounds: don't smoke, light a flame or touch light switches, open the doors and windows, turn the gas off at the meter if you can reach it safely and it isn't in a cellar or basement, get everyone out, and call the National Gas Emergency Service free on 0800 111 999 before anything else — before calling us.

When to call
Book 4–6 weeks before expiry — you can renew up to two months early and keep the same renewal date, so there's no reason to run it close. If you smell gas, or a carbon monoxide alarm sounds: don't smoke, light a flame or touch light switches, open the doors and windows, turn the gas off at the meter if you can reach it safely and it isn't in a cellar or basement, get everyone out, and call the National Gas Emergency Service free on 0800 111 999 before anything else — before calling us.
