Polypipe’s findings show only 27% of housebuilders have comprehensive knowledge of Parts L and O

One in four UK housebuilders admit to having only a ‘limited’ or ‘minimal’ understanding of several key UK Building Regulations, according to new research commissioned by Polypipe Building Products.

The survey found that 25% of housebuilders lack detailed knowledge of three Approved Documents, while less than a third (27%) said they had a ‘comprehensive’ grasp of the updated regulations. Just 31% reported feeling confident and up to date on changes introduced to improve energy efficiency and mitigate overheating risks.

The regulations in question – Approved Documents Part L (conservation of fuel and power), Part O (overheating) and Part F (ventilation) – came into force in 2022 to support the UK’s Net Zero 2050 target. Since then, further amendments have been made.

Polypipe’s findings show only 27% of housebuilders have comprehensive knowledge of Parts L and O, while 31% are confident in applying Part F.

The research also identified gaps among clients. Only 26% of housebuilders described their clients as ‘highly informed’ on legislative changes, compared to 55% who said knowledge was ‘mixed’.

Dean Asher, head of technical sales at Polypipe Building Products, said: “The construction industry is still trying to get its head around a huge swathe of new legislation that was enacted three years ago. Some of these regulations have since been amended further. Building Regulations will be subject to continued and further changes as the industry evolves. Our research demonstrates it can be challenging for housebuilders to keep up with the constant change.”

Asher added that knowledge-sharing remains critical: “Housebuilders trust consultants, peers and professional networks the most. Partnering with other experts in the industry is key to navigating a sector of ever-changing rules and guidelines. All stakeholders up and down the supply chain must work together to make sure new homes are built to current and future standards.”
