Unlike an electric boiler, a gas boiler needs to be regularly serviced to maintain it and keep it efficient in the home. You want to be able to run a hot bath when you need a soak, and you need to be able to heat the house and feel comfortable to do it because your utility bill won’t be sky high. For that to happen you need an annual service on your gas boiler and that means booking to speak to a Gas Safe or OFTEC Registered engineer.
