In late June 2019 BSI published PAS 2035:2018 – Specification for the Energy Retrofit of Domestic Buildings. This has the potential to revolutionise the entire retrofit process. The government have proposed to make compliance with the Standard a mandatory requirement for all projects in the long-term. It will be mandatory on projects using ECO funding following a transitionary period expected to run until summer 2021. There is a 20% uplift available in ECO funding for projects that comply with PAS2035 before then.
It has the full backing of government, who have sponsored its development. Nobody in the energy efficiency sector can afford to ignore it, and those who do will be left behind.
