Energy Savings

Before & after.
Real kWh numbers.

A typical 3-bed London semi heated by an old combi boiler uses around 1,840 kWh a month in winter. Swap that for a properly sized air source heat pump and you're looking at 460 kWh — a quarter of the energy, a fraction of the bill.

Figures based on EPC band C, average London home, current Ofgem unit rates. Actual savings vary by property — we'll run the numbers on yours for free.

What clients say
★★★★★

Fitted a multi-split across three bedrooms in two days. The summer of '25 was the first one we actually slept through.
