What are the signs of a gas leak?


The first signs of a gas leak can be the smell, as natural gas is odourless and colourless. To help with detecting leaks they add in a harmless chemical called Mercaptan to give a distance odour, which is remarkably like rotten eggs. Yuck!


You may be able to hear a hissing sound coming from the appliance or pipe that has the leak.


Plants require a certain amount of oxygen to live. If you have a gas leak within your home then the oxygen levels decrease and house plants can no longer survive and will start to die.
