‘Are changes to Part L and Part F of the Building Regulations increasing the dampness, and deterioration of our traditional and historic buildings built with solid walls causing health issues for those who occupy them’.

There are industry concerns that changes to Approved Documents L and F of the Building Regulations 2010 that came into force in England on 15th June 2022 and in Wales on 23rd November 2022 have little regard for the thermal improvement of traditional and historic buildings. This uplift in the regulations is a stepping stone approach by government to achieve net zero carbon by 2050. We can expect more government changes to the Building Regulations in 2025 to achieve further carbon emission improvements of up to 80%. Without proper guidance in the Approved Documents, we will see ever increasing dampness and deterioration in our traditional and historic buildings built with solid walls causing health issues for those who occupy them.
