The government has widened its New Homes Accelerator to speed up stalled housing schemes, adding support for sub‑500‑home projects and launching a London‑focused service. Ministers say more than 125,000 homes have been moved forward since 2024 as Phase 2 goes live on Thursday 29 January 2026, with a call for developers, landowners and councils to submit sites for help.

Two things stand out for the market. First, the pivot to smaller sites should benefit regional and SME housebuilders who typically work at this scale and can start quickly once conditions are met. Second, a clear delivery push in the capital via ‘NHA LDN’ and the planning support offer ‘ATLAS LDN’ aims to cut decision times in boroughs facing staff and expertise gaps. Industry leaders from Persimmon and Keepmoat publicly welcomed the shift to smaller sites and the focus on getting schemes moving. (gov.uk)

Seven locations are joining the programme now, with a cluster in the Oxford–Cambridge corridor: three parcels at North West Bicester (Howes Lane, Himley Village and Hawkwell), Wretchwick Green in south‑east Bicester, and Stewartby Brickworks in Bedfordshire. Government material references over 11,400 homes tied to these sites, alongside a wider near‑term pipeline approaching 60,000 homes across the East Midlands, East of England and South East. (gov.uk)

London gets a bespoke set‑up. The Greater London Authority will lead NHA LDN and ATLAS LDN to help boroughs progress complex sites, with the aim of turning stalled permissions into starts before the end of this Parliament. A year‑round portal now routes site submissions nationally, with London entries handled by the GLA. This is a practical response to borough capacity constraints and the need for specialist planning input. (gov.uk)

How far does this move the dial? Recent official data show 208,600 net additional homes in England in 2024–25, with building‑control completions in 2025 Q1 at about 36,000 on a seasonally adjusted basis. To reach the government’s multi‑year ambition, today’s pipeline acceleration has to translate into sustained increases in starts and completions through 2026 and 2027. (gov.uk)

Planning remains the choke point. Detailed approvals fell sharply in early 2025, hitting a 13‑year low, according to industry analysis reported by the Financial Times. The London arm of the Accelerator is designed to tackle exactly this problem by strengthening casework capacity and providing expert reviews where borough teams are stretched. (ft.com)

The jobs story is material for local economies. HBF‑commissioned research suggests housebuilding activity supports around 3.4 jobs per dwelling, with the government’s 1.5m‑home ambition associated with hundreds of thousands of roles annually across trades, supply chains and professional services. These are industry estimates, but they frame why faster delivery matters for growth. (hbf.co.uk)

There are execution risks that go beyond planning permission. Schemes often hinge on utilities, transport links and environmental permissions. The programme cites recent progress at Hampden Fields in Aylesbury after securing Flood Risk Activity Permits with the Environment Agency-an example of how resolving one regulatory piece can free a whole project to proceed. Expect more interventions of this type in Phase 2. (gov.uk)

For investors and SME builders, the near‑term test is conversion: how many of these sites actually break ground in 2026, and how quickly can the London service turn casework into decisions. We’ll be watching the government’s new submissions portal and the GLA’s throughput, as well as quarterly starts and completions, for signs that this policy push is feeding into real‑world supply.
