In short
- Proposals expected in the week of August 24 would let England’s devolved mayors intervene in major planning decisions and direct councils to approve or reject qualifying projects.

The British government is expected to propose wider planning powers for England’s devolved mayors, allowing them to intervene in decisions on large housing and commercial developments as part of its effort to accelerate construction.
The proposals, reported on August 23, 2026, would allow mayors to call in qualifying local planning decisions and direct councils to approve or refuse them. They would also permit upfront approval in some cases, enabling developers to begin work without making a separate application.
The planned thresholds cover developments of more than 150 homes, commercial projects exceeding 15,000 square metres and buildings at least 30 metres tall. Any intervention would still have to comply with national planning policy and applicable local plans, while ministers would retain a backstop power.
Prime Minister Andy Burnham acknowledged concerns that shifting authority to mayors could weaken the role of councillors, members of Parliament and residents. He argued, however, that mayoral review could work in both directions—challenging councils that block appropriate development as well as proposals whose effects on communities are unacceptable.
Ten of England’s 14 devolved mayors, representing different parties, have backed the approach, according to the report. The change would broadly align their authority with powers granted earlier in 2026 to London Mayor Sadiq Khan to address stalled housing sites.
The package is also expected to give mayors more influence over how Homes England funding is allocated locally and allow development levies to support major infrastructure. A consultation is due to be published during the week beginning August 24.
The government says it is a little more than one-quarter of the way toward its target of building 1.5 million homes in England over five years. The Liberal Democrats oppose the proposal, arguing that it would reduce the voice of residents and local councillors.
The measures have not yet been adopted. Their final scope may change following publication and consultation.
