Question to the Department for Business, Energy and Industrial Strategy:

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.
