Residents have told us that it can be very inconvenient when gas servicing contractors call without a booked appointment.

We’re doing

We’re working with our contractors to review their ‘cold calling’ approach. We want to be sure our contractors are only doing this in clearly defined situations such as when the resident has not been at home for a number of previously booked appointments or the annual gas safety certificate (which is a legal requirement) is about expire.
