It is estimated the investment will reduce lifetime carbon emissions by up to 40t in the smallest properties to 200t in the three-bed flats.

The new ground-source heat pump infrastructure will consist of a series of communal boreholes connected to individual heat pumps within each property, Kensa calls this system ‘ambient shared ground loop arrays'. The shared ground loop array infrastructure is deemed a district heating system, qualifying the project to be part-funded via the Energy Company Obligation and receive a 20-year income via the UK's Non Domestic Renewable Heat Incentive.

Dr Matthew Trewhella, MD of Kensa Contracting, said: "Together Housing's landmark investment in ground-source heat pumps via the Procure Plus framework is a pioneering step by a social housing provider to address the emissions of existing housing stock and fuel poverty levels; their commitment to innovation, community, and the environment is a benchmark for fellow housing associations and new build developers to follow."
