Common questions

I can smell gas. What should I do?

Don't use switches or naked flames, open windows, turn off the gas at the meter if safe, leave the property and call the National Gas Emergency line on 0800 111 999. Then call us to inspect and repair.

Do I legally need a CO alarm?

Rules vary, but a carbon monoxide alarm near gas appliances is strongly recommended for every home, and required in many rented properties. We can supply and fit them.
