What is PAS 2035?
PAS 2035 is the new over-arching document in the retrofit standards framework introduced following the recommendations of the Each Home Counts review. PAS 2035 essentially provides a specification for the energy retrofit of domestic buildings, and details best practice guidance for domestic retrofit projects.
It is evident that significant improvements need to be made within the energy efficiency of the UK’s building stock, if the country is to meet its global carbon commitments. In 2015 the government commissioned the Each Home Counts review to identify and tackle the high level of failure present in domestic retrofit, and to determine a better process for the retrofit of energy efficiency and renewable energy measures. PAS 2035 (PAS 2035:2019 Specification for the energy retrofit of domestic buildings) was introduced as a result of this review, with the backing of industry and the government department for Business Energy and Industrial Strategy (BEIS).
Following a transitionary period the government has proposed to make compliance with PAS 2035 mandatory for all public funded projects which would include ECO funded retrofit projects (see below).
