Minimum insulation pre-conditions

Precondition 1:

All Band D homes receiving any heating measure other than FTCH or a DHC must first have at least one insulation measure installed as part of the same ECO4 project before the heating measure is completed. The eligible insulation measures are: roof insulation (flat roof, pitched roof, room-in-roof), wall insulation (cavity wall, solid wall), party wall insulation and floor insulation (solid and underfloor). Park homes must receive floor, wall and ceiling insulation.

Please note that Loft Insulation (LI) is not an eligible insulation measure to meet Precondition 1 for SAP Band D properties.
