Chancellor promises no more major changes to building regulations this parliament except to improve building safety
The chancellor has pledged to take a more “proportionate” approach to housebuilding regulation, lowering biodiversity net gain requirements and ruling out major regulatory changes.

John Healey, in his Budget speech, today announced there will be no major changes to building regulations for the remainder of the parliament, except for improving building safety including implementing Grenfell Inquiry recommendations.
Healey said: “To get more homes built, I’m drawing the line on constant changes to building regulations”.
In Budget documents, the Treasury said: “The cost of building a home is at a record high, both due to underlying inflation of materials and labour costs, and increased burdens due to regulation and policy costs.”
Healey announced biodiversity net gain (BNG) requirements will be removed on brownfield sites up to 1.5ha.
The government will ”consider how amendments to regulations could support development by being more proportionate”. It added “this will give industry and councils greater confidence to invest, build, and deliver homes.”
Healey also announced the establishment of a Better Regulation Executive – a joint unit between Treasury and Number 10 – to implement the “government’s vision for a streamlined and proportionate regulatory system”. A chair will be appointed shortly.
The government will also bring forward a Regulation for Growth Bill which will relax rules to allow new technologies and approaches to be trialled for cross-sector regulation.
