From first call to handover — our boiler installs routine

Old boiler removed, new one fitted, system flushed, controls set up. Usually a single day for a straight swap, two for a full system change.

Are Alpha boilers reliable?▾
Better than their reputation. The E-Tec Plus range carries a 10-year warranty and we've had few warranty calls on the units we've fitted.
How long does a boiler install take?▾
A straight combi swap is usually one day. A boiler relocation, conversion, or full system change is typically 1–3 days.
How much does a new boiler cost fitted?▾
Most combi swaps run £2,200–£3,800 fitted depending on brand and any system upgrades. We give you a written fixed price after a free survey — no obligation.
