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 delivered using public funding, following a transitionary period expected to run until January 2021.
It has the full backing of government, who have sponsored its development. Even when powerful lobbyists representing the powerful supplier groups went on the attack, the commitment to the core principles at the heart of the PAS remained intact. Nobody in the energy efficiency sector can afford to ignore it, and those who do will fall foul of the new regime.
