IN Brief:
- Ministers have dropped plans for automatic cash-payment substitution of affordable housing on medium sites.
- The proposal would have allowed qualifying developers to replace direct provision with a commuted payment.
- Housebuilders will continue to manage on-site affordable delivery alongside Section 106 negotiations and registered-provider demand.
The government has dropped a proposal that would have allowed developers of medium-sized housing sites in England to meet affordable-housing requirements through cash payments instead of providing the homes directly on site. The decision was confirmed alongside the updated National Planning Policy Framework on 17 August after the proposal attracted substantial opposition during consultation.
The Ministry of Housing, Communities and Local Government had explored giving applicants on medium sites discretion to discharge social and affordable housing obligations through a payment in lieu. In its broadest form, the proposal would have required authorities to accept the cash alternative where the site met the new medium-development definition.
The government’s consultation documents said the option was being considered because smaller housebuilders can struggle to find registered providers willing to acquire Section 106 homes. Prolonged negotiations can delay schemes, create uncertainty over receipts, and place particular pressure on developers without the balance sheets available to national housebuilders.
At the same time, the consultation acknowledged that on-site delivery supports mixed communities, influences land-price expectations, and converts the planning obligation directly into completed affordable housing rather than requiring a council to turn a later cash receipt into another development.
The final decision keeps that preference for on-site provision rather than creating a blanket medium-site exemption. Off-site provision and commuted sums remain possible where justified through the existing planning process, but developers have not been given the automatic discretion proposed during consultation.
The policy matters commercially because affordable housing affects a scheme long before the homes are built. Tenure mix, land value, financing, sales assumptions, build sequence, specification, Section 106 negotiations, and agreements with registered providers can all depend on how many affordable units are expected to remain within the development.
Developers that had hoped medium sites would gain a routine cash-payment option must therefore continue to model direct provision into their projects. That can mean accommodating different tenures, handover arrangements, funding milestones, and purchaser requirements within the same construction programme rather than simplifying the physical development and making a payment to the authority.
The construction consequences are practical rather than abstract. Mixed-tenure developments can include different fit-out requirements, inspection processes, warranties, sales procedures, and handover dates, while registered-provider requirements need to be coordinated alongside those applying to market-sale units.
The original proposal was intended to address a genuine difficulty. Housing associations and other registered providers have faced financial pressures of their own, and some developers have struggled to secure buyers for Section 106 units on terms that support the original appraisal. A planning permission containing affordable homes is less useful to a builder if there is no purchaser capable of completing the transaction.
Allowing a cash payment would have removed that immediate sales dependency for the developer, but it would have transferred the delivery problem elsewhere. A local authority receiving the money would still need land, design, planning permission, procurement, funding, and a contractor before the contribution became an affordable home.
The argument therefore came down to where the delivery risk should sit. Developers favoured greater flexibility where on-site obligations were preventing schemes moving forward, while housing organisations and rural campaigners warned that routinely moving affordable provision away from medium sites could reduce supply in places where such developments account for a substantial share of new affordable housing.
The government has retained the emerging medium-development category while declining to attach the proposed automatic commuted-sum right to it. The consultation framework defines medium housing development as schemes of 10 to 49 homes on sites of up to 2.5 hectares, reflecting an attempt to create more proportionate policy and regulatory treatment for projects commonly delivered by SME builders.
Other measures intended to streamline medium sites can continue without removing the on-site affordable-housing expectation. Government work on planning obligations, proportionate requirements, and SME delivery is therefore likely to continue, because abandoning this particular option does not solve the Section 106 market problems that prompted it.
For contractors, developers, and consultants, the immediate effect is greater certainty over the appraisal assumption. Medium developments cannot proceed on the basis that affordable-housing obligations will routinely be converted into a cheque. The familiar work of agreeing tenure, finding a registered-provider route, coordinating specifications, and managing Section 106 delivery remains in the programme.
That may not be the simplification some SME builders wanted, but it avoids creating a system in which an easier planning obligation on one site leaves another public body trying to turn a commuted sum into land, consent, procurement, and eventually a home. Construction has enough delayed conversions already without adding another one deliberately.
