Renewable Energy Alternatives Heat Pump

Air Source Heat Pump Installation

Heat pumps are relatively new technology in the UK, although they have been popular in Scandinavia and mainland Europe where renewable energy is plentiful. Air Source heat pumps provide renewably sourced electricity for your home, and can be up to three times more efficient than a traditional gas boiler.


We are MCS-certified installers of Air Source Heat Pumps, meaning you'll be able to claim a government grant of £5,000 per household to install an air source heat pump system (ASHPs) - this will usually cover between 75% and 50% of the cost.
