See how people in Bristol and Somerset are using the Green Deal to improve their homes

The aim of this website is to encourage people in Bristol and Somerset to undertake low-carbon home improvements through the Green Deal.


It gives householders who have done this – for example by insulating their home, installing micro-renewables or draught-proofing their windows and doors –  the chance to share this with others, and to rate the installers who carried out the work.


You can browse the map below to find case studies near you, filtering the results by the type of home and by the type of improvement.


We are the Centre for Sustainable Energy, a registered charity based in Bristol. Why not check out our Home Energy Advice website to get impartial support and advice before undertaking your new home energy improvement project.
