Why the UK Scrapped a Plan That Could Have Meant Fewer Affordable Homes
On 17 August 2026, the UK government dropped a plan that would have made it easier for some developers to skip building affordable homes. The reversal was tucked into a 150-page planning reform document published the same day The Guardian.
Affordable housing refers to homes built at below-market rents or prices, usually because the government requires developers to include a certain share of them in new housing projects. The now-scrapped plan would have created a new category for medium-sized developments — sites with 10 to 49 homes. Builders on those sites would have been allowed to pay cash instead of actually constructing affordable homes on-site. The Treasury, led by Rachel Reeves, was particularly keen on the change. Ministers hoped that easing the rules would help boost housebuilding and move the government toward its goal of 1.5 million new homes by the end of the parliament. The idea first appeared in a government working paper called "Reforming Site Thresholds," published in May 2025 gov.uk.
The government ran a public consultation — essentially an open invitation for people and organisations to share their views — from December 2025 to March 2026. The response was overwhelmingly negative. Of the 910 people and groups who responded, 41% were strongly opposed to the rule change and 18% were strongly in favour. The government has now confirmed it will not go ahead with the proposal.
The loudest opposition came from housing experts who crunched the numbers on what this would mean for rural areas. The National Housing Federation (NHF), a body representing affordable housing providers, analysed government data and found that in England's most rural areas, more than half of all affordable homes are built on developments of 10 to 49 houses. The NHF warned that the proposed change could have cost the country 32,000 affordable homes over the next decade. Kate Henderson, the NHF's chief executive, welcomed the government's decision to keep the on-site affordable housing rules for medium-sized sites.
The broader picture is a government stuck between two goals that pull in different directions. On one hand, it wants to hit a very ambitious target of 1.5 million new homes. On the other, it needs to protect the supply of affordable homes, which housing groups say is already too small. The Treasury liked the idea of letting developers pay cash instead of building affordable homes on-site because that money could be pooled and spent on housing projects elsewhere. But the NHF's data showed a flaw in that thinking: in rural areas, a medium-sized development is often the only realistic way to get affordable homes built. Cash payments are hard to use effectively in those areas because land and developer interest are already scarce.
This reversal follows a related decision from October 2025, when ministers confirmed plans to reduce affordable housing quotas in London as part of efforts to reverse a collapse in housebuilding The Guardian. The London reduction went ahead; the rural one did not. That difference suggests the government is adjusting its approach depending on the region — accepting lower affordable housing requirements in expensive urban areas where builders are struggling, but backing away from changes that would have stripped affordable homes from rural England.
Angela Rayner, who served as housing secretary from July 2024 to September 2025 and was reappointed to the role in July 2026, is now overseeing a planning reform package that keeps the on-site affordable housing rules for medium sites while moving ahead with other measures. The 17 August document also announced that councils will be told to apply a "default yes" to housing developments near well-connected train and tram stations, a change designed to encourage building in areas with good public transport.
What is still unclear is whether the government can meet its 1.5 million home target without the rule change that the Treasury and smaller developers wanted. The consultation revealed a split in the housing sector: large housing associations and rural advocacy groups fought hard against the change, while smaller developers argued that lighter rules on medium sites would help them build more homes. By siding with the former on this question while pushing other reforms forward, the government is taking a step-by-step approach rather than overhauling the whole system at once.
The 32,000-home figure from the NHF now stands as a measure of what was saved, not what was lost. Whether those homes actually get built on medium-sized rural sites depends on much more than this one rule change: whether grant funding is available, whether local policies support affordable housing in rural areas, and whether smaller developers are willing to take on projects in rural markets where profit margins are thin and the affordable housing requirements remain fully in place.
