This guidance was withdrawn on

This competition is now closed to applications, and we have announced the successful bids.

Overview

This Whole House Retrofit (WHR) cost reduction trajectory competition is a key early step in accelerating a reduction in domestic retrofit costs. It supports:

  • our ambition to halve the cost of retrofitting existing buildings to the same standard as new builds by 2030
  • the government’s Fuel Poverty target to bring as many fuel poor homes as reasonably practicable to EPC band C by 2030
  • our aspiration for as many homes as cost effective, practical and affordable to reach the same standard by 2035

The competition

The competition was launched in May 2019 and is now closed. A total of £7.7 million has been awarded to the first 3 winning organisations in the Whole House Retrofit competition. Read more about the winning organisations.

The 3 winning projects had to demonstrate these key outputs:

  • demonstration of cost reduction through process innovation
  • evidence of sources of cost reduction
  • approximately 400 homes improved overall (at least 75 per project) and achieving at least a 30 kWh/m2 performance figure as part of an appropriate ‘fabric first’ approach for the building type
  • development of retrofit plans, installation of whole house retrofits, commissioning with residents, and post installation monitoring.
