Who we are and what we do

In September 2024, Central Government announced the Warm Homes: Local Grant to fund tackle fuel poverty by supporting local authorities’ delivery of energy performance and low carbon heating upgrades to low-income homes in England. 

The Climate Emergency team at London Borough of Waltham Forest Council are working with Hestia Heath and Homes Ltd Trading as Domna to carry out a pilot project to undertake outreach to owner occupied and private rental properties in the Borough. The aim is to deliver transformative energy upgrades to residents in low-income areas, targeting households burdened by high energy bills and striving to make a tangible impact in alleviating fuel poverty across the borough.

Domna uses technology to make retrofits more accessible and make it easier to identify properties that need measures to improve residents' home energy efficiency.
