Gas Leak Investigation
Gas-safety fault investigation for situations where an installation needs checking after the immediate emergency risk has been dealt with or where a gas-system fault is suspected.
Gas leak and tightness investigation
Tightness testing
Testing of the installation where loss of tightness is suspected and it is safe to carry out the checks.
Pipework investigation
Tracing accessible gas pipework and connections where the source of a fault is not obvious.
Appliance isolation checks
Investigation to help separate an appliance issue from a pipework or installation issue.
Post-emergency follow-up

Remedial advice
Clear explanation of any repair, isolation or replacement work needed after the fault is identified.
Smell gas or suspect an active gas escape?
Call the National Gas Emergency Service immediately on 0800 111 999. Do not rely on this form or wait for a normal appointment.
Safety comes before fault finding
This service is for proper investigation once it is safe to work on the installation. We do not use a website enquiry as the first response to an active suspected gas escape.

Gas Leak Investigation FAQs
What should I do if I can smell gas now?
Do not wait for an online enquiry. Call the National Gas Emergency Service on 0800 111 999 and follow their safety advice.
Can you investigate a gas leak after the supply has been isolated?
Yes, where the situation has been made safe and investigation or remedial work is then required.
Does a failed tightness test always mean replacing all the pipework?
No. The next step depends on where the loss is found, access and the condition of the installation.
