Leak detection service
Suspect a gas leak? Get everyone out, leave the doors open and call the National Gas Emergency line on 0800 111 999 first. For tracing a known or intermittent leak, we can help.
A gas leak is a safety risk and must always be treated as an emergency first. If you can smell gas, hear hissing, or your carbon monoxide alarm is sounding, stop reading, get everyone out, and call the National Gas Emergency Service on 0800 111 999. Do not try to find the leak yourself with anything that could spark.
Once the immediate danger has been made safe, specialist detection helps with locating an intermittent or hard-to-find gas leak, or confirming where pipework is failing. We trace gas leaks across Cornwall using tracer gas leak detection and the right procedures, and we work with Gas Safe registered engineers for any work on the gas installation itself.
Related services: if you are dealing with water rather than gas, see our water leak detection and central heating leak detection. For more on how leaks are traced, read our Water Leak Guide.
A gas leak is never something to leave for later. Beyond the bill, the real risks are fire, explosion and carbon monoxide, which is why it has to be treated as an emergency.
If you suspect gas, act straight away:
✓get everyone out into fresh air✓do not switch anything electrical on or off, and avoid naked flames✓turn the gas off at the meter if you can do so safely✓call the National Gas Emergency Service on 0800 111 999
Once you are safe, we trace the source precisely with proper equipment, so the leak can be made good and verified rather than guessed at.
Our method
Gas detection instruments to identify and follow an escape
Tracer gas and pressure testing to confirm and locate pipework faults
Targeted access so the failed section is exposed with minimal disruption
Coordination with Gas Safe registered engineers for repair
Safety-led, so emergencies go to the National Gas Emergency Service first
Local to Cornwall, from Land's End to Launceston
Precise tracing that minimises disruption
We work alongside Gas Safe registered engineers
We cover the whole of Cornwall, from Land's End to Launceston. That includes Truro, Newquay, St Austell, Falmouth, Penzance, Bodmin, Bude and Liskeard. See all the areas we cover.
Treat it as an emergency. Open doors and windows, get everyone out, do not touch electrical switches or use naked flames, turn off the gas at the meter if it is safe to do so, and call the National Gas Emergency Service on 0800 111 999 immediately. Do not try to trace the leak yourself.
A smell of rotten eggs, a hissing or whistling sound near pipework or appliances, a yellow rather than blue flame on a gas hob, excessive condensation, or feeling unwell or drowsy indoors. Carbon monoxide is a separate, odourless risk, so fit a CO alarm.
Work on the gas installation must be done by a Gas Safe registered engineer. We specialise in tracing and locating the leak precisely, and we coordinate with Gas Safe engineers so the repair is targeted and compliant.
