Questions people ask
What is the Boiler Upgrade Scheme?
It's a government grant in England and Wales that gives up to £7,500 off an air source or ground source heat pump. Your MCS-certified installer applies for it, and the grant comes off your bill.
Will a heat pump work in an older house?
Often, yes, but it may need better insulation or bigger radiators. A good installer will do a heat loss survey before quoting.
Heat pump or new boiler?
A boiler costs less upfront. A heat pump costs more, but the grant closes much of the gap and running costs can be lower with the right tariff. Getting quotes for both is the easiest way to compare.
