The brownfield passport would make yes the “default answer” to brownfield development if it meets certain “design and quality standards”.

According to the planning reform working paper, this would not give automatic planning permission to sites, but would be “setting clear parameters [that], if met, serve as accepted markers of suitability, with approval becoming the default and a swifter outcome”.

The paper added that this would lower risk, cost and uncertainty associated with securing planning permissions.

The government has opened a call for evidence to answer questions such as how urban areas could be identified or defined, what the minimum scale of development should be, how local development orders could be used and what caveats should be imposed, to name a few.

The government said that it would discuss these with key stakeholders before specific proposals are consulted on and new policies put in place.

In its manifesto, Labour pledged to build one-and-a-half million homes over the next government, adding that it would take a “brownfield-first approach”.

The manifesto said that it would be “prioritising the development of previously used land wherever possible, and fast-tracking approval of urban brownfield sites. But brownfield development alone will not be enough to meet our housing need”.
