PAS 2035 Retrofit Home Assessment

Publicly Available Specification (PAS) 2035 is a UK standard, introduced in 2019, for the energy retrofit of domestic buildings. It was developed to address issues of quality and performance in retrofit projects and provides a robust framework for the design and installation of energy efficiency measures (EEMs). One of the key components of PAS 2035 is the Whole House Assessment (WHA), which forms the basis for any retrofit project.
