England mayors to gain powers over big planning schemes

If you have ever watched a big housing scheme creep through the planning system and wondered who can break a deadlock, this reform is worth your attention. In an announcement published on 23 August 2026, the government said mayors across England will be given 'call in' powers over the most significant planning applications in their areas. (gov.uk) That matters because planning is not only about bricks and mortar. It decides where homes go, how tall buildings can be, and whether jobs arrive with the roads and services a place needs. The argument here is really about who should make those choices: a council, a mayor, or, in rare cases, ministers in Whitehall. (gov.uk)

Under the proposal, a mayor would be able to step into large applications that affect local growth and tell a council to take the scheme forward or refuse it. The government says this brings mayors outside London closer to powers the Mayor of London already has, and GOV.UK planning guidance explains that London boroughs already have to refer certain strategically important schemes to City Hall. (gov.uk) **What this means:** if a big scheme stops being only a neighbourhood argument and starts to look like a regional one, the final decision may move up a level. That could make stalled cases move faster, but it also means more political weight sits with a single elected mayor. (gov.uk)

The thresholds are designed to catch only the largest schemes. Outside London, the new rules would cover developments with more than 150 homes, more than 15,000 square metres of commercial floorspace, or buildings above 30 metres, which the government describes as roughly ten storeys. (gov.uk) So this is not about your neighbour’s loft conversion or a small parade of flats. It is about the kinds of proposals that can remake a town centre, add a new estate, or change the skyline around a station. Once you see those thresholds, you can also see the political choice behind them: ministers want mayors involved when a scheme is big enough to shape growth beyond one council boundary. (gov.uk)

Councils, though, are not being removed from the picture. The government says local authorities will still decide the majority of planning applications, and it pointed to recent delivery figures in places including Salford, Leeds and Knowsley to argue that many councils are already getting homes built at scale. It also says every decision must still follow planning rules, the local plan and national policy, while applicants keep their right of appeal and ministers keep a reserve power to intervene. (gov.uk) **What this means:** local democracy is not vanishing, but it is being rearranged. For the biggest schemes, the debate may shift from 'what does the planning committee think?' to 'whose judgment carries more weight when a council and a mayor disagree about growth?' (gov.uk)

Another part of the announcement could matter just as much. Ministers say mayors will be able to grant up-front permission for some development so building can begin without a developer making a standard application first. Earlier GOV.UK guidance on 'permission in principle' shows the thinking behind this sort of change: settle the basic case for development early, then deal with the technical details later. (gov.uk) Supporters will say that cuts delay and gives builders more certainty. Sceptics will ask whether residents get enough say before the outline of a project is effectively fixed. We will need the detailed rules, due the week after the announcement, to judge how much room communities will really have to influence these decisions. (gov.uk)

The reforms also reach beyond the planning committee room. The government says mayors will get a stronger voice over how housing money is spent in their areas. Homes England will still lead on the biggest projects, but its funding and technical support are meant to follow priorities agreed with local mayors, and Homes England’s 2026 investment prospectus says grant allocations will respond to both national and local priorities, including those set by mayoral authorities. (gov.uk) There is real money attached to that promise. Ministers say £1.3 billion from the national land and infrastructure fund has already been allocated to seven established mayoral areas, alongside £234 million of brownfield funding for seven mayoral strategic authorities and £1.5 billion committed through the Housing Accelerator Fund. **Why that matters:** power over planning is far more useful when it comes with money for land, roads and site preparation. (gov.uk)

Mayors outside London are also set to gain the power to charge a levy on development for major infrastructure. That mirrors a tool London already uses: City Hall says the Mayoral Community Infrastructure Levy was introduced to help finance the Elizabeth line, and GOV.UK guidance explains that community infrastructure levies are charges on development used to pay for supporting infrastructure. In plain English, new building can be asked to help fund some of the transport and public works it depends on. (gov.uk) Put together, these changes show devolution in its most practical form. Power is moving away from Westminster, but it is also moving, in some cases, away from individual councils and towards regional mayors. If you want the one-sentence takeaway, it is this: the fight over who decides where homes go in England is being redrawn, and the people affected will need much clearer ways to follow those decisions and challenge them when necessary.
