A gas leak in your home or business isn’t something you can ignore. If you think you can smell gas or your carbon monoxide alarm’s gone off, it’s important to act quickly — and safely.
At Manchester Gas and Heating, we’re fully qualified to handle gas leak detection and repair work across the city. Here’s what to look out for and the steps to take if you think something’s not right.
Signs You Might Have a Gas Leak
-
Smell of gas (rotten egg smell – added for safety)
-
Headaches, dizziness, or nausea
-
Hissing sounds near gas pipes or appliances
-
Dead or dying plants indoors (could mean gas is escaping)
-
Carbon monoxide alarm going off
If you notice any of these signs, don’t ignore them — even if you’re not 100% sure. It’s always better to be safe.
What to Do Immediately
If you suspect a gas leak:
-
Open windows and doors to let fresh air in
-
Turn off the gas at the meter if you know how
-
Avoid switching lights or appliances on or off (sparks can ignite gas)
-
Leave the property if the smell is strong
-
Call the National Gas Emergency line on 0800 111 999 right away
Once you’re safe and the emergency team has visited, it’s time to call in a qualified Gas Safe engineer to check and repair the issue properly.
Why Gas Leaks Happen
Gas leaks can be caused by:
-
Old or poorly installed pipework
-
Loose connections
-
Faulty appliances (like boilers or cookers)
-
Accidental damage to gas lines
-
Lack of regular servicing
That’s why we always recommend an annual gas safety check — it’s one of the easiest ways to prevent problems before they start.

Frequently Asked Questions
-
What should I do if I smell gas in my home?
Open windows and doors, turn off the gas at the meter if you can, and leave the property. Then call the National Gas Emergency line on 0800 111 999. -
Who should I call after the emergency service has checked the leak?
Once the emergency team makes things safe, contact a Gas Safe registered engineer like Manchester Gas and Heating on 07960 042563 to inspect and repair the issue properly. -
How do I know if I have a gas leak if I can’t smell it?
Some leaks may not have a strong smell. Watch for signs like headaches, dizziness, nausea, or your carbon monoxide alarm going off. -
Is a carbon monoxide alarm the same as a gas leak detector?
No. A carbon monoxide alarm warns you about CO from faulty appliances. It doesn’t detect natural gas leaks. You should have both for full protection. -
Can I fix a gas leak myself?
No. Gas repairs must only be carried out by a qualified Gas Safe engineer. DIY gas work is illegal and unsafe. -
How often should I have my gas appliances checked?
We recommend a yearly gas safety check, especially for boilers, cookers, and fires. It helps prevent leaks and keeps everything running safely. -
I’m a landlord — do I need a gas safety certificate?
Yes. Landlords are legally required to have annual gas safety checks and provide tenants with a valid certificate (CP12). We can handle this for you. -
What causes most gas leaks?
Leaks are usually caused by faulty pipework, loose fittings, or old appliances that haven’t been serviced. Regular checks can help spot issues early. -
How long does it take to fix a gas leak?
It depends on the source and how easy it is to access. In most cases, we can find and repair the leak on the same day. -
Is Manchester Gas and Heating Gas Safe registered?
Yes — all our engineers are fully Gas Safe registered. Always ask to see a Gas Safe ID when hiring someone for gas work.
