Gas Leak Warning Signs and What to Do Next

A suspected gas leak should be treated as a safety issue, not a maintenance task to investigate casually. Gas may be noticed by smell, unusual appliance behaviour or other warning signs. If you believe there is an active leak, prioritise getting people away from danger and seeking professional help.

For more detail on the service itself, see our gas leak detection page.

Possible warning signs

A strong gas odour, hissing near pipework, unexplained gas use or appliances behaving abnormally can indicate a problem. Not every symptom confirms a leak, but suspected gas faults should be taken seriously.

What to do if you suspect an active leak

If it is safe to do so, move away from the suspected area. Avoid flames, smoking and anything that could create a spark. Do not continue trying to locate the leak yourself.

  • If there is immediate danger, contact emergency services.
  • Contact the relevant gas emergency service or distributor where appropriate.
  • Arrange inspection by an appropriately licensed gas fitter.

Do not rely on smell alone

Gas systems and appliances can develop faults that are not obvious. If there is a reason to suspect a problem, professional testing is more reliable than trying to confirm it by smell.

Gas leak detection

A licensed professional can test the system, isolate sections and determine whether the issue is in the pipework, appliance connection or another part of the installation.

Repairs should follow the diagnosis

The correct repair depends on where the fault is found. Replacing random fittings without identifying the source can leave the underlying issue unresolved.

Safety first

If you are unsure whether a situation is safe, leave the area and seek professional or emergency assistance rather than continuing to investigate.
