To uplift UK households through energy efficiency and carbon reduction.

Contributing to the UK Government’s Net Zero 2050 strategy through targeted residential retrofits.

Our Accomplishments

We have actively contributed to national retrofit objectives through successful delivery under LAD, SHDF, ECO3, and the ongoing ECO4 Scheme. Our primary focus is to prioritise households living in fuel poverty by making modern heating upgrades like efficient gas boilers, heat pumps with solar panels, and insulation. These combined measures helped families enjoy warmer homes while cutting down on carbon emissions and energy waste.

Local Authority District (LAD)

A Local Authority District (LAD), or simply district, is a geographic area in the UK for which a local government body is responsible. It’s a level of subnational division used for local government purposes. LADs can include various types of authorities, such as metropolitan districts, non-metropolitan districts, unitary authorities, and London boroughs in England.

Social Housing Decarbonisation Fund (SHDF)

SHDF stands for Social Housing Decarbonisation Fund, a UK government initiative that provides funding to improve the energy efficiency of social housing. The goal is to reduce carbon emissions and fuel poverty by upgrading buildings with measures like better insulation and renewable energy sources. 

150+ Projects

(which include Solar PV, External Wall insulation, Loft insulation and/or smart heating controls)

ECO 3 (Economic Cooperation Organization)

ECO3 is a UK government scheme that provides funding for energy efficiency improvements in homes, aiming to reduce carbon emissions and tackle fuel poverty. It’s a successor to the Energy Company Obligation (ECO) scheme. Specifically, ECO3 focuses on insulation and heating measures, particularly for vulnerable consumer groups.
