Gas Safety Services

Emergency Gas Leak Detection

We use electronic gas detectors to locate the leak source — pipework joints, appliance connections, meter unions, or flexible hoses. We isolate the faulty section and make safe before any repair work begins.

Gas Pipe Pressure Testing

After any suspected leak, we pressure-test the pipework to confirm there are no further leak points before restoring the gas supply. A written pressure test report is provided for your records.

Appliance Isolation & Reconnection

If a gas appliance is found to be unsafe, we can cap it off immediately and reconnect it once repaired or replaced. This includes boilers, gas cookers, gas fires and tumble dryers.

Gas Pipe Repair & Rerouting

Corroded, damaged or incorrectly installed gas pipework can be repaired in-situ or rerouted where necessary. All pipework work is inspected and pressure-tested on completion.

CP12 Landlord Gas Safety Certificate

Landlords are legally required to have gas appliances checked annually. We carry out full gas safety inspections on all appliances and issue a CP12 (Gas Safety Record) from £75.

Dangerous Appliance (ID) Notices

If an appliance is unsafe to use, we issue a formal Immediately Dangerous (ID) or At Risk (AR) notice. We explain the risk, cap the appliance, and advise on repair or replacement options.

Why Gas Safe Registered Matters

It is illegal to work on gas appliances in the UK without Gas Safe registration. All Trusted Plumber London engineers working on gas are directly Gas Safe registered — not sub-contracted. You can verify any engineer's Gas Safe ID card on the Gas Safe Register website (gassaferegister.co.uk) before work begins.

After any gas work, we issue a signed Gas Safety Record detailing every appliance tested, the test results, and the engineer's Gas Safe number. This record is required evidence for insurance claims and property sales.
