Heat pumps

In most cases, air source heat pump installations are classed as ‘permitted development’ - meaning you don’t need planning permission. It’s worth noting, though, that there is still guidance to be met, such as the unit being at least 1 metre from the property boundary, and if you live in a conservation area or listed building then additional restrictions may apply.

Regardless of the type of heat pump, they all essentially transfer heat from one place, such as the air, ground or water, to another, such as to heat inside your home. They do this using electricity to power a compressor and evaporator, which is similar to a household refrigerator but in reverse. 

Heat pumps are a very efficient option for heating your home. You could expect around 250-300% efficiency from a typical air source heat pump, and 350-400% efficiency from a ground source heat pump! The exact efficiency will vary depending on the type, make and model of heat pump you choose, as well as the average temperature where you live, and how well insulated your home is. 

The Boiler Upgrade Scheme (BUS) is a government scheme offering grants of up to £7,500, to help homeowners with the cost of installing energy efficient, low-carbon heating systems such as heat pumps.
