The smell of household gas distributed through the town of Stornoway is to change from Monday (28th October).

SGN, the company that distributes natural and green gas across Scotland, is also responsible for the liquified petroleum gas (LPG) distributed in Stornoway.

LPG is completely odourless, so an additional smell is added to the gas before it enters Stornoway’s gas network, to help people smell gas leaks and report them quickly.

Project engineer Luke Macdonald, who has been managing the changeover, said: “Currently, we use tetrahydrothiophene to add an oily or tarry smell to our gas. The replacement odorant – ethyl mercaptan – is generally described as more organic and likened to the smell of decaying vegetation. You may already be familiar with this smell from using portable gas cylinders for camping or barbecues.”

Customers are being reminded to report any smell of gas at any time, before, during or after the change, to the National Gas Emergency number on 0800 111 999.
