Matt Williams, Managing Director for Polypipe Building Products and the BMBI Expert for Heating and Cooling, comments:
“Since the start of 2025, the Chancellor of the Exchequer has been making increasingly positive noises about growth, specifically around speeding up planning approvals for the development of new homes. The government is backing housing developments in key areas such as zones close to commuter transport hubs, with a view to providing housing that targets working families. These ideas were formally presented in the new Planning and Infrastructure Bill in March.

“Coming out of 2024, we can reflect on a difficult year which, on the surface, may not have delivered particularly positive market conditions. However, there were many progressive actions being taken in the housing industry regarding heating and cooling. Most, if not all, major housing developers are now actively planning for their heating systems of the future, and planning for The Future Homes Standard.
“2024 was the year when UK housebuilders started deep diving into what heating solutions they may couple with Air Source Heat Pumps in new build homes, with several housing developers now potentially reviewing adoption of product solutions within their house designs.
“Fundamentally changing a heating system which has been commonplace since the 1970s is a huge undertaking! It presents numerous challenges, but it also presents plentiful opportunities. At Polypipe, we are working in partnership with our customers to explore these improvements and efficiencies in the construction process as part of introducing innovative technologies to give the UK construction industry real solutions to tomorrow’s problems.”
