For premises in a multi-storey building that do not include the top floor and are connected to a district heating system (DHS) under CERO or CSCO, pre-condition 2 must be met. This technical report can be used to evidence instances where there are technical reasons why a cavity cannot be filled. In such instances, this report will satisfy pre-condition 2 for the premises it relates to. This report can also be used to evidence that walls are of solid wall construction.
Further information on the ECO2 requirements can be found in our ECO2 Guidance.
