The government’s newly published Impact Assessment for the Planning and Infrastructure Bill estimates that proposed reforms could deliver up to £7.5 billion in economic benefits over the next ten years.
The Bill aims to streamline planning processes to make it faster and easier to build up to 1.5 million homes and deliver critical infrastructure, such as public transport improvements and clean energy projects.
According to the assessment, measures in the Bill could reduce delays, provide greater certainty for developers, and lower costs for businesses—factors that may support increased investment in housing and infrastructure. The analysis received a ‘green rating’ from the independent Regulatory Policy Committee, indicating it meets standards for robustness and reliability.
The assessment does not yet reflect additional changes made at the Committee Stage of the Bill, such as proposals to speed up the pre-application process for major infrastructure like wind farms and new roads. Government analysis suggests these changes could bring an additional £1 billion in economic value over the course of this Parliament.
These projections come alongside previous estimates linked to reforms in the updated National Planning Policy Framework (NPPF), which the Office for Budget Responsibility has said could raise housebuilding to its highest level in over four decades and generate an additional £6.8 billion by 2029/30.
The Bill forms part of the government’s broader strategy to support economic growth by addressing housing shortages and accelerating infrastructure delivery.
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.’
