Written evidence from the Royal Institution of Chartered Surveyors, the End Fuel Poverty Coalition, AgilityEco and the Green Homes Group told us how the failures with ECO are undermining public confidence in retrofits, potentially with negative impacts on our ability to reduce both fuel poverty and carbon emissions.88 The Department told us it is “tightening up” the current system, and that it expects this to help rebuild the public’s confidence in the ECO schemes and wider retrofits.89 It told us, for example: • As of March 2025, it is a requirement for retrofit coordinators, who manage the design and installation of the measures, to physically visit each project site to help ensure the design is appropriate for the specific property.90 83 C&AG’s Report, para 4.12 84 FEE0019 85 Q 131 86 FEE0023 87 Q 132 88 FEE0014, FEE0015, FEE0016, FEE0023 89 Qq 97, 99, 100 90 Q 99 22 • Organisations across the system are working together to share information and collectively make more informed decisions.91 • TrustMark and the certification bodies suspended 38 installer businesses, representing 81% of the external wall insulation market.
