An average 3 bed property with a gas boiler will cost between £1850.00 & £2500.00. Certain factors such as size of property, brand of boiler and energy supply used will alter this.
A general boiler change in an existing location will take a full day. If the system requires a power flush, this will go into day two. If the installation is complicated and requires a longer flue installation or new gas pipe, this may also make the job exceed one day.
In many cases, existing radiators are compatible with a new boiler installation. We would suggest that changing old radiator valves and installing thermostatic valves at a minimum to keep up withL2 energy regulation.
For an average 3 bed property with 7-10 radiators, a 25KW boiler is enough. A double radiator is approx 2KW, and a single radiator is approx 1KW - this gives a good rule of thumb when sizing a boiler. The amount of hot water flow you wish to acquire should also be taken into consideration.
If your boiler is non condensing (usually 20 years + old) and are on some kind of benefit or state credit, you could be entitled to a free boiler installation. The scheme is called ECO 4.
