The Department of Business, Energy & Industry Strategy (BEIS) has released their Guide to Best Practice – Retrofit Floor Insulation – Suspended Timber.
The aim of this guide is to provide a clear reference document for surveyors and installers considering the suitability for suspended timber floors located above an unheated space, to receive thermal upgrades (insulation), when installed below the floorboards or timber decking. It also applies to timber floors when situated above an unheated integral garage, unheated storeroom, or an unheated basement.
Please note that for measures to be compliant in ECO, they will need to adhere to the BEIS requirements referenced in this email AND be PAS compliant, with a valid guarantee, and pass technical monitoring.
We anticipate that Ofgem will confirm their requirement that the BEIS guidance is followed and will be reviewing the TM questions to ensure the appropriate checks are made.
