Gas Leak Investigation
If you suspect a gas leak, you need clear answers quickly. A gas leak investigation checks your gas pipework and appliances, confirms whether a leak is present, and pinpoints the source so the right repairs can be planned and your property made safe.
More information
What a gas leak investigation covers
A Gas Safe registered engineer will carry out regulated safety checks to identify the problem and reduce risk. The service typically includes:
- Leak testing to confirm whether gas is escaping from pipework or an appliance
- Tracing and narrowing down the likely leak location
- Visual inspection of accessible pipe runs, meter area and appliance connections
- Safety checks of affected appliances where appropriate
- Clear explanation of findings and recommended next steps
- Written confirmation of results where required
When this service is most useful
Arrange an investigation if you:
- Smell gas indoors or near the meter box
- Have repeated loss of gas pressure or unexplained appliance issues
- Have had building work, new appliances, or alterations to pipework
- Manage a rental or commercial property and need prompt, documented action
- Need reassurance after a suspected incident or report from a tenant
What happens during the visit
The engineer will ask what you have noticed, then carry out a structured set of tests and checks. This usually involves isolating sections of the installation, checking tightness, and inspecting connections and accessible pipework to narrow down the source. You will be talked through what is safe to use, what must stay off, and what needs repair.
After the investigation
You will receive a clear summary of what was found and what to do next. If urgent action is needed, you will be advised on immediate safety steps and repair options. If no leak is detected, you will still get practical guidance on monitoring and any further checks that may be sensible.
