Deputy prime minister Angela Rayner has launched a new expert group to speed up delivery of stalled housing sites and drive growth.

Hundreds of thousands of new homes stuck in the planning system or partially built are being targeted by the New Homes Accelerator.

The new team will bringing together key players, including government agencies, local planning departments and housebuilders, who will work to resolve specific local issues and deploy planning experts on the ground to work through blockages at each site identified.

This includes looking at barriers to affordable housing delivery where relevant. 

Interventions could see the New Homes Accelerator provide resources to support local planning capacity where there are barriers and work across the board to make sure planning decisions are made in a timely fashion.   

Government analysis suggests 200 large sites have outline or detailed plans ready to go but are yet to begin construction – the team is already getting started on some of those that would benefit from early interventions.

Deputy prime minister Angela Rayner said: “For far too long the delivery of tens of thousands of new homes has been held back by a failure to make sure the development system is working as it should.

“This government has a moral obligation to do everything within our power to build the homes that people desperately need and we won’t hesitate to intervene where we need to.

“Our New Homes Accelerator will quickly identify blockages, fix problems and support local authorities and developers to get shovels in the ground.”

Further work will get under way to accelerate sites including Stretton Hall in Leicestershire, Tendring Colchester Borders Garden Community in Essex and Biggleswade Garden Community in Central Bedfordshire which have the potential to unlock more than 10,000 new homes when completed.

The New Homes Accelerator was announced as part of the chancellor’s speech outlining the government’s national mission to drive growth in July and since then, four large housing sites are already progressing that will deliver over 14,000 homes across Liverpool, Worcester, Northstowe and Sutton Coldfield.  

Landowners, local authorities and housebuilders have been invited to come forward with details of blocked sites that have significant planning issues, so government can better understand the scale of the problem across the country to tackle the obstacles that are preventing the delivery of new homes.

David O’Leary, executive director of the Home Builders Federation, said: “The planning process and everything associated with it delivers too little land and has long been a significant constraint on house building.

“Government has shown a welcome desire in the weeks since the election to address the problems.

“A lack of planning department capacity and misaligned incentives for other public bodies and statutory consultees has created a process with huge uncertainty. This creates an abundance of risk resulting in longer development timescales and severe challenges in particular for small and medium-sized house builders.

“Adopting a pragmatic approach to planning will increase the pace at which new homes are built and help to turn around ailing housing supply.

“Unlocking homes and delivering new communities will boost growth and support job creation while providing young people with access to new, more affordable housing. The housing market is complex and we look forward to working with government to ensure that all aspects of the housing market are functioning more effectively.”

The New Homes Accelerator builds on wider government plans to turbocharge housebuilding, improve local decision-making and modernise the planning system through the Planning and Infrastructure Bill recently announced at the King’s Speech.  

This is alongside the government’s overhaul of the planning system that will see new mandatory housing targets for councils and bolster local resources with 300 additional planning officers.
