Why a heat pump
Efficient warmth that works with your home.
More heat per unit
A heat pump turns one unit of electricity into three or more units of heat — far more efficient than direct electric heating.
Lower-carbon warmth
Clean, electric heating that cuts your home's carbon footprint — and runs on the solar you generate.
Works with your home
Designed to work with your radiators or underfloor heating, and sized properly for a warm, even home.
Handled to MCS standard
Full MCS certification, the DNO and paperwork, and a company owner on site — done properly.

Heat pump questions
Will a heat pump actually keep my home warm?
Yes — a properly designed system keeps your whole home warm, even in winter. The key is correct sizing and design, which we do at your free survey.
Do I need new radiators?
Not always. We assess your existing radiators and only recommend changes where they're needed for efficiency and comfort.
Is it noisy?
Modern air source heat pumps are quiet — typically no louder than a fridge from a short distance away.
What does it cost to run?
Because a heat pump is several times more efficient than direct electric heating, running costs are competitive — and your survey gives you the real figures for your home.
How long does installation take?
Most installations take a few days, and we handle the MCS certification and all the paperwork throughout.
