Emergency safety steps in Croydon

CRITICAL: What to Do If You Smell Gas

STOP — don't use switches

Do not turn any electrical switches on or off. Do not use your phone inside the building. Do not light matches or cigarettes. Electrical sparks can ignite gas.

Open windows, evacuate

Open all doors and windows to ventilate. Get everyone out of the building. Do not re-enter until the building has been declared safe by a Gas Safe engineer.

Call National Gas Emergency

From outside the property, call the National Gas Emergency number: 0800 111 999 (free, 24/7). They will isolate the supply. Then call us to carry out the repair and safety check.

Gas leaks can be fatal. Do not attempt to find or fix a gas leak yourself. Only Gas Safe registered engineers are legally permitted to work on gas appliances and pipework. Carbon monoxide (CO) is odourless — fit a CO alarm near every gas appliance.

Common questions

Gas leak emergency Croydon: frequently asked

What should I do if I smell gas in Croydon?

If you smell gas in Croydon: do not use any electrical switches, do not use your phone inside the building, do not light any flames. Open all windows and doors, get everyone out immediately, and call the National Gas Emergency number 0800 111 999 (free, 24/7) from outside the property.

Can you attend a gas leak emergency in Croydon today?

Yes — we provide 24/7 emergency gas leak attendance across all of Croydon, including Croydon, Purley, Thornton Heath, Norbury and surrounding areas. Our Gas Safe registered engineers carry electronic gas detection equipment and can isolate, locate, and repair leaks on the same visit in most cases.

How do I know if I have a gas leak vs a CO leak in Croydon?

Natural gas has a distinctive rotten-egg smell added by gas suppliers specifically so you can detect it. Carbon monoxide (CO) is entirely odourless and colourless — you cannot smell it. A CO alarm is the only way to detect a CO leak. Both situations require immediate action and evacuation. If you are unsure, treat it as a gas emergency and call 0800 111 999.

How much does gas leak repair cost in Croydon?

Gas leak repair costs in Croydon depend on the source and extent of the fault — typically £150–£350 for most repairs. The National Gas Emergency service (0800 111 999) will isolate the supply at no cost. We charge for locating the fault, carrying out the repair, pressure-testing the pipework, and issuing a written safety report.
