The government has published its latest impact assessment of the Planning and Infrastructure Bill, with its highest estimate showing £7.5bn in potential gains over the next decade.

The central estimate was £3.2bn, with the most conservative outlook at £1.3bn.

The Planning and Infrastructure Bill is one of several measures introduced by the Labour government, with its target of 1.5 million new homes a central pledge at last year’s general election.

The government added that its latest impact assessment does not include recent amendments tabled at committee stage.

According to the government, these steps could add a further £1bn in economic activity.

“Getting Britain building will not only boost economic growth but ensure we deliver the homes and infrastructure working people deserve,” said Angela Rayner, deputy prime minister and housing secretary.

“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.”
