Heat pumps for a bungalow
Based on the average floor area and assessed energy use for a bungalow in England and Wales.
What the numbers look like

These are averages, not your home
Everything above describes a typical property of this kind, using published energy certificate statistics. Your own figures will differ — often substantially, since floor area alone varies by a factor of three between areas.
We cannot price most of this work: there is no published cost dataset we can stand behind for insulation or heat pumps, so the savings above come with no payback. How we work these out.
