Heat Pumps: Costs

Question for Department for Business, Energy and Industrial Strategy

UIN 21263, tabled on 23 June 2021

To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment his Department has made of the average cost of fitting a new heating system to a typical UK property to make it compatible with a heat pump.

Earlier this year, the Department published a report on heat distribution systems. This report concluded that the typical cost of retrofitting an entire house with larger radiators for a low temperature heating system, like a low temperature heat pump, would be approximately £1,700 for a one- to two-bedroom house, £2,200 for a three-bedroom house and £2,900 for a five-bedroom house. However, not all homes will require a radiator retrofit to become suitable for a heat pump, meaning the costs would be lower. In addition, the use of high temperature heat pumps is likely to significantly reduce the need to alter existing heat distribution systems.
