A replacement boiler has to suit the house, the hot water you use and where the boiler can sit. We look at the system already in the home and explain the options before any work is booked. The quote covers the boiler, the work involved and what will be left as it is. A question we get is whether a particular street is covered. We confirm the postcode before the visit. Another is what a quote includes: the boiler, the work involved, and what will stay as it is.
