- Before it’s piped to domestic consumers, an odorant is added to natural gas to make it easier to detect if there’s a leak. It’s often described as a rotten egg or cabbage smell.
- Leaking gas from a small opening may cause a hissing noise.
- If the cost of your gas bill has suddenly jumped (and you haven’t been using more than usual) it could be a sign there is a slow gas leak.
- A yellow, orange or red gas flame colour on your gas appliances means there could be a fault or a gas leak. It could also mean your gas burners need a clean so check those too.
If you suspect you have a gas leak in your home, you should open the windows and call your local gas plumber straight away.
