Free Home Energy Assessments

Free 2-hour consultations and advice on smarter homes

Existing Homes

The Sustainability Trust Home coach will come to your home and offer free advice on how to make it warmer, drier and cheaper to run. They will look at areas such as where heat is being lost, sources of dampness, the hot water system, how the power bill might be reduced, and how the sun’s energy might be better utilised.

A key benefit of this service is its independence. You will receive independent advice on products relating to heating, insulation and ventilation, and how these might best suit the individual needs of your home.

You will receive an action plan with written, professional and independent advice tailored to suit.

Please note free assessments will only be available while funding allows.
