Gas Safe Registered Engineers
Gas Safety Certificates (CP12) Across South East London
Every landlord letting a property with gas appliances needs a current gas safety certificate, renewed every twelve months. Our Gas Safe registered engineers carry out the checks and issue the certificate, at a fixed price, across Bromley, South East London and Kent.







In Short
A gas safety certificate, or CP12, confirms the gas appliances in a property are safe. Under the Gas Safety (Installation and Use) Regulations 1998, every landlord must hold a current certificate and renew it each year. GPM London issues gas safety certificates across South East London and Kent at a fixed price, with a yearly reminder so it never lapses.
What We Do
Compliant, on time, every year
Under the Gas Safety (Installation and Use) Regulations 1998, a landlord must have every gas appliance, flue and pipe in a let property checked each year by a Gas Safe registered engineer. We carry out those checks, make anything unsafe safe, and issue the gas safety certificate on completion. You get a fixed price agreed before we book in, a fast turnaround that works around your tenants, and the option of a yearly reminder so the certificate never lapses and you stay compliant.

What We Do
What a Gas Safety Check Covers

Every Gas Appliance
Each gas appliance in the property is checked for safe operation, correct pressure and safe combustion, with the result recorded for each one.

Flues & Pipework
The flues and gas pipework are checked for leaks, blockages and correct installation, so fumes clear safely and the supply is sound.

Certificate Issued
The gas safety certificate (CP12) is issued on completion, listing every appliance and its result, your proof of compliance for the year.

Why Landlords Choose GPM
We know a certificate is only useful if it arrives on time, so we work around your tenants and turn checks around quickly, with a fixed price agreed before we book in. If an appliance is unsafe, we make it safe and give you the price to put it right rather than leaving you with a problem and no fix. Every certificate is issued under GPM London Plumbing & Heating Limited, Gas Safe registered number 966779, and we can set up a yearly reminder so you are never caught out by a lapsed certificate. We look after single properties and portfolios alike across London and Kent.
