Survey on Non-Standard Cavity Walls and Lofts in Great Britain

[ALEO Admin]

EST has been commissioned by the Department of Energy and Climate Change (DECC) to review evidence on non-standard cavity walls and lofts in Great Britain.

To ensure this review is robust, they have prepared an online questionnaire to help them to gain a better understanding of:

• How to identify the number of non-standard cavities and lofts in Great Britain
• The types of non-standard cavity and non-standard loft that exist
• Which of these are fillable and non-fillable
• The methods, costs and savings associated with filling these.

This survey should take roughly 30 minutes to complete. There is a significant amount of information to supply, so please feel free to fill in as little or as much of the survey as you can reasonably answer.

Attached below is some additional information to describe some of the wall types discussed in the survey.

If you would like to discuss the questionnaire further, please get in touch with Joe Payne – joe.payne@est.org.uk – who is a member of the research team at Energy Saving Trust.
