Mayors to force through 150+ home schemes: the proptech opportunity

For proptech founders and investors, the planning system has long been the industry's biggest friction point. Andy Burnham's proposals to let mayors call in decisions on schemes over 150 homes — and grant upfront permission so developers can start without applying — signal a structural shift toward faster, more predictable development pipelines. That predictability is exactly what enables proptech platforms in planning analytics, modular construction, and build-to-rent underwriting to scale.

Andy Burnham is preparing to unveil proposals next week that would hand England's devolved mayors sweeping new powers to override local planning decisions, 'call in' major applications, and grant upfront permission so developers can begin work without first securing full planning consent. The plans, reported on 23 August 2026 by multiple outlets citing a Sunday Times interview, would apply to housing schemes of more than 150 homes, commercial developments over 15,000 square metres, and any building of 30 metres or more in height — roughly ten storeys. Ten of England's 14 devolved mayors have already signalled support, and the measures would bring them into line with the Mayor of London, Sadiq Khan, who was granted equivalent powers earlier in 2026 as an emergency intervention to unblock stalled sites and accelerate affordable housing delivery.

Andy Burnham's proposals to let mayors call in decisions on schemes over 150 homes — and grant upfront permission so developers can start without applying — signal a structural shift toward faster, more predictable development pipelines.

The context is a housing supply crisis that has become a defining economic and political issue. The Government is just over a quarter of the way towards its target of building 1.5 million homes in England within five years, a shortfall that has kept land values elevated, rents rising, and construction pipelines volatile. Under the proposed framework, mayors would not act without constraint: decisions must remain consistent with planning rules, locally set plans, and national policy. But the practical effect is a meaningful shift of authority away from district councils and towards strategic, mayoral-level decision-making — a rebalancing Burnham explicitly defended, arguing that 'sometimes challenge does need to be made to local decision-making, and actually it cuts both ways.'

For the development and investment community, the most consequential element is the power to grant 'upfront permission.' By allowing developers to secure outline approval before applying for detailed consent, the reforms target one of the most persistent bottlenecks in English housebuilding: the layered, sequential, and frequently contested planning process that can add years and millions in holding costs to large schemes. For builders of 150-plus-unit estates, mid-rise towers, and large commercial floorspace, upfront permission effectively converts planning risk into a more predictable, front-loaded negotiation with a single strategic authority. That has direct implications for project finance, land banking, and institutional capital, which have historically priced UK development risk higher precisely because of planning uncertainty.

The proposals also give mayors a stronger voice in how national housing funding from Homes England is deployed in their regions, and the ability to charge a development levy to fund major infrastructure. This coupling of planning power with fiscal tools matters: it lets mayors package approvals with infrastructure commitments — transport, utilities, public realm — that are often the real blocker for large sites, and to capture value from the very development they are enabling. The ten supportive mayors suggest a broad coalition, but the exclusion of four regions, and the explicit acknowledgment that councillors, MPs, and constituents could be disempowered, points to the friction the formal announcement will face.
