Smell Gas Right Now? Do This First
Safety comes before any plumbing. If the odour is strong or sudden:
- Leave switches, plugs and anything electrical exactly as they are.
- Turn off the appliance valve only when it is within arm's length and away from the smell.
- Walk out to the yard or street before making any call.
- Hissing at the meter or from the footpath? That goes to the distributor's emergency number.
Once you are on the footpath, ring (02) 4093 0558 and describe the smell or sound.
What Are the Signs of a Gas Leak?
Your nose is not the only warning. Look out for:
- That sulphur odour, heaviest around the stove, the heater or the meter box.
- A soft whistle you can hear near a joint.
- Stovetop flames gone floppy and yellow.
- Feeling light-headed or headachy indoors, then fine in fresh air.
- A strip of dead lawn or shrubs tracing a buried run.
- Bubbles when soapy water is brushed over a fitting.
Any one of them warrants a detector check. A small leak stays small for a while, then doesn't.
Finding the Leak, Step by Step
- 01
Make it safe
The appliance or the isolated section of line is shut down so the leak can be worked on.
- 02
Trace it with the detector
Gas detectors read concentrations along the line, and the pipe locator traces the run behind walls and under the ground.
- 03
Expose and repair
The faulty joint, section or fitting is replaced, whether that's a bayonet connection behind a heater or a corroded length of copper under the floor.
- 04
Test and certify
A gauge holds the pipe at pressure, the detector sweeps each joint once more, and the compliance paperwork follows.
With the pipe sealed, any new cooktop or heater is a job for our gas appliance installers.
How Is a Gas Leak Repair Priced?
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.
What sits in the figure:
- Reaching the escape: a joint inside a wall cavity means more opening up than one exposed under the floor.
- How much line needs replacing, from a single joint to a full corroded run.
- The pipe material and its age, which changes both the repair and the fittings.
- Whether the job lands inside normal hours or carries the after-hours rate.

When We're Not the Right Call
Gas escaping from the meter assembly or the main under the footpath is fixed by the distributor, and you report it on their emergency number. An appliance fault under a current manufacturer's warranty, like a failed heater valve, goes to the maker's service agent first.
Questions From Around the Gas Work
Do you come out after hours for a gas smell in Swansea?
Yes. A gas smell cannot wait for Monday, and the phone is answered through the night. A night or weekend visit costs more, and you hear that figure before anything is agreed.
Can a gas leak in an old Swansea cottage be fixed without replacing the whole line?
It can be. The detectors narrow the leak to a joint or a single corroded section, and where the rest of the copper is sound, one repair and a pressure test does the job. If the line is thin along its length, the quote covers the replacement instead.
Is a gas smell near the meter my responsibility or the gas network's?
It depends where the escape is. Pipework from the outlet of your meter into the house is yours, and we repair it. A smell strongest at the meter box or coming from the footpath points to the distributor, who handles the meter and the main.
Do you test the line after the repair?
Every time. The repair is followed by a pressure test and a check at each fitting with the gas detector, and nothing gets signed off until the line holds. That test is part of the job, not an extra.
