Reforms aimed at accelerating the construction of new homes, transport links, and clean energy projects could add up to £7.5 billion to the UK economy over the next decade, according to
fresh government analysis.
The Impact Assessment for the Planning and Infrastructure Bill, released today (Tuesday, 6 May), highlights how the government’s new pro-growth measures are set to significantly speed up development across the country.
At the core of the reforms is a push to build 1.5 million new homes and fast-track essential infrastructure—including public transport upgrades and renewable energy projects. These efforts are part of the government’s broader Plan for Change, which aims to grow the economy and improve everyday life for working people.
The Bill is expected to reduce delays, lower business costs, and increase investment certainty, driving further economic growth. Officials believe the estimated £7.5 billion boost may even understate the full potential benefits, as the assessment does not include recent amendments that will streamline the pre-application stage for major infrastructure projects—anticipated to generate an additional £1 billion within this Parliament.
This projected economic impact comes on top of changes already made through the updated National Planning Policy Framework (NPPF). The Office for Budget Responsibility has projected that the NPPF reforms alone could lead to the highest levels of housebuilding in more than 40 years, contributing a further £6.8 billion by 2029–30.
Deputy Prime Minister and Housing Secretary, Angela Rayner said:
“Getting Britain building will not only boost economic growth but ensure we deliver the homes and infrastructure working people deserve.
“This landmark pro-growth Bill will get spades in the ground and the foundations laid for a new generation of homes, as we deliver on our Plan for Change.”
The Regulatory Policy Committee has given the Bill’s Impact Assessment a ‘green rating’, confirming it meets rigorous standards for evidence and analysis.
The Bill supports the government’s goal to approve at least 150 major infrastructure projects during this Parliament—17 have already been decided. Additional reforms, introduced during Committee Stage but not yet included in the official assessment, are also expected to simplify the approval process for projects such as windfarms, roads, and other key developments.
These measures are designed to help Britain become a clean energy leader, protect households from energy shocks, and put more money back in the pockets of working people.
