Everything from the gas meter to the natural gas appliances (known as downstream) must be completed by a Gas Safe Registered Installer – this is a legal requirement and is the responsibility of the customer

We carry out regular assessments on areas for future development and we aim to take gas to concentrated areas where the anticipated uptake is highest.
