About our gas safety certificates service
A gas safety certificate (CP12) is a legal requirement for landlords every twelve months, and a sensible check for homeowners at the point of buying, selling or simply for peace of mind.
We test every gas appliance, check flues and ventilation, log flue-gas analysis readings, and email your certificate the same day the work is done.
