As with all ECO measures, we require that 100% of a room in roof insulation measure is installed, unless there are reasonable grounds for not doing so. We have produced this document to provide clarity to the ECO supply chain on what constitutes 100% of a room in roof insulation (RIRI) measure.
Update 1 September 2016
We have amended this document to provide further detail and examples on what constitutes 100% of a RIRI measure and how this measure should be scored. In addition we have included an FAQ to clarify which PAS annexes installers must be certified to, in order to install RIRI measures under ECO.
Please contact ECO@ofgem.gov.uk if you have any further queries.
