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.
To respond to the survey, please visit: https://response.questback.com/energysavingtrust/nonstd
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.
