Retrofit Resources

Welcome to the

Building Retrofit Information Hub for homeowners

An initiative from HGN to bring together people, information and professional expertise to help with the challenge of making homes (and workplaces) comfortable year-round in the face of high heating bills and the need to cut carbon emissions.

We’re going to be expanding this section but are starting small, with links below to what we reckon are very good sources of information. (Last update February 22nd 2021)

IMPORTANT If you are struggling to keep your home warm and deal with the costs, the advice team at Keep Herefordshire Warm can help – Get help here

Embarking on retrofit:

a whole house approach

Done right, this can make big improvements to comfort levels and can reduce energy consumption and carbon emissions by 60-80%. It’s a large financial commitment and can be a disruptive process, but can be done successfully in stages. We strongly recommend that anyone planning a retrofit should start with a Whole House Plan.
