Free and low-cost energy efficiency surveys for Bristol homes

Save money and improve the comfort and energy efficiency of your home 

An internal energy-loss survey of your house 
A local non-profit project called C.H.E.E.S.E (Cold Homes Energy Efficiency Survey Experts) can reveal faults and help you to decide how best to reduce your energy use and cut your fuel bills. C.H.E.E.S.E uses thermal imaging to identify heat loss from draughts and poor insulation, and can suggest remedies, many of which are cheap and easy to implement, and may be suitable even if you don’t own your home. After a survey, you are supplied with a video and verbal report, and an energy monitoring and action pack. A modest charge is made, from £60.00, depending on the size of your home. But surveys are FREE to low-income households. 

The C.H.E.E.S.E Project survey procedure 
On a cold day, your house is heated overnight to ten degrees above the outside temperature, then an extractor fan is fitted to one external door to reduce the internal pressure and to draw in cold air. The house is surveyed with a thermal-imaging camera to reveal cold spots caused by poor insulation and draughts. You accompany the surveyor with a tablet screen to view the thermal images and see first-hand what is found. A video is recorded of the thermal images together with the commentary and the surveyor’s answers to your questions. (If you are on a low income, we can help with the cost of the over-night heating.) 

Householder briefing on heat loss and potential remedies 
Following the survey, you are briefed on the problems and how they might be remedied, some with low-cost DIY. We leave you with a memory stick of the images and video for subsequent reviewing. 

The survey and briefing take about two hours or more for a large house. 

Energy monitoring and action 
You can also be loaned, for two weeks, a pack containing simple-touse meters to monitor electricity use, as well as guides for DIY energy-saving techniques. 

The C.H.E.E.S.E team will later follow-up to obtain feedback and to find out how the survey has helped you to save energy and money, and increase comfort in your home.
