The guide in brief
The Boiler Upgrade Scheme grant
Homes in England and Wales can get £7,500 off the cost of an air source heat pump through the Boiler Upgrade Scheme. You do not apply yourself: your MCS certified installer claims it for you and takes it off your quote, so you never pay the full price up front. The guide explains who qualifies and what the installer needs from you.
Running costs and winter performance
A well-designed heat pump turns each unit of electricity into roughly three to four units of heat. It is sized from a room-by-room heat loss calculation at the coldest temperatures expected where you live, so it keeps the house warm in January, not just in spring. The guide shows how running costs compare with a gas boiler and what makes the biggest difference to your bills.
Noise, installation and upkeep
Modern outdoor units are quiet, and where the unit goes is checked against the noise rules before anything is fitted. Most installations take two to three days once the survey and design are agreed, and an annual service keeps the system running efficiently and your guarantees valid. The guide walks you through each step, from the first survey to switching the system on.
