Air Source Heat Pumps

Clean, efficient heating — for any UK home.

The benefits

Why switch to a heat pump?

Heat pumps are the heating system of the future — and with government grants now available, the upfront cost has never been lower.

  • Dramatically lower carbon footprint vs gas boiler
  • Eligible for the Boiler Upgrade Scheme (up to £7,500)
  • Works in temperatures as low as -20°C
  • Heats both radiators and underfloor heating
  • Provides domestic hot water
  • Compatible with solar PV and battery storage

How does it work?

An air source heat pump absorbs heat from outside air — even at temperatures as low as -20°C — and uses it to heat your home via radiators, underfloor heating or a warm air system. A separate unit also provides domestic hot water.

Is my home suitable?

Most UK homes are suitable for a heat pump. We carry out a full property assessment to confirm suitability and size the system correctly for your heat demand. Good insulation improves performance, but is not always a prerequisite.

Boiler Upgrade Scheme

The UK government's BUS grants up to £7,500 towards a new air source heat pump. We handle all the paperwork and deduct the grant from your installation cost.
