IN Brief:
- Vistry estimates the proposed model could support up to 30,000 homes each year.
- Purchasers would initially buy at least 60% using a conventional mortgage.
- Institutional funding and proposed National Housing Bank participation would support the remaining share.
Vistry has proposed a shared-ownership structure which it estimates could support up to 30,000 additional homes a year, using institutional investment and targeted public backing alongside conventional buyer mortgages. The model remains under development, with the housebuilder seeking support from government, lenders, investors, and housing organisations before it can become an operational product.
Vistry calls the proposal Choice-led Shared Ownership. It has published the model in a white paper developed after engagement with more than 35 organisations spanning registered providers, institutional investors, government representatives, and other housing-sector bodies.
The structure is intended to allow eligible first-time buyers to select a qualifying new-build property rather than purchasing only from homes pre-allocated to conventional shared ownership. Buyers would acquire a minimum 60% share through a standard mortgage and deposit, with rent charged at 3.5% on the remaining portion.
Funding for that residual interest would come primarily from institutional capital together with a lender-provided debt tranche. Vistry is also proposing a National Housing Bank equity contribution equivalent to around 1% of the property value, while purchasers would retain the ability to increase their ownership through staircasing and potentially reach full ownership.
The white paper estimates that the structure could support 150,000 homes over five years, or approximately 30,000 annually. It also models a potential reduction in public grant requirement of as much as £10.5bn when compared with delivering an equivalent number of properties through conventional grant-funded shared ownership.
Those numbers are modelling outputs rather than committed housing volumes. No 150,000-home programme has been approved, and the proposal still requires agreement between parties whose interests do not always align neatly: housebuilders need sales certainty, investors require dependable returns, mortgage lenders need acceptable underwriting terms, and government support would have to be structured without creating an excessive public liability.
The construction relevance is tied directly to sales absorption. A consented housing site does not automatically translate into a continuous building programme if purchasers cannot meet deposit and mortgage affordability requirements. Developers can build ahead of sales to a point, but completed inventory consumes working capital and eventually slows the rate at which later plots are brought forward.
Vistry’s model attempts to widen the pool of purchasers able to transact on new homes without requiring government to fund the full affordability gap through conventional grant. If it succeeded at scale, the effect would be felt through build rates on live developments rather than through the creation of additional planning permissions alone.
The proposal would also add another funding structure to already complicated mixed-tenure developments. Large housing sites increasingly combine private sale, affordable rent, shared ownership, build to rent, and institutional partnerships, with each tenure carrying different funding and delivery requirements. Choice-led Shared Ownership would have to sit within that mix without making sales, valuation, legal documentation, or handover processes unmanageable.
Standardisation would be critical. A product intended to work across tens of thousands of homes would require common approaches to valuation, rent calculations, staircasing, repairs, resale, default, consumer protection, and treatment of the investor-funded share. A structure that required bespoke negotiation on every development would struggle to achieve the scale assumed in the white paper.
Vistry proposes establishing a taskforce during 2026 to develop the operating model, bringing together housebuilders with support from the Ministry of Housing, Communities and Local Government and other participants. The company says the process would include assembling a pipeline of potential homes, engaging consumers, and defining the framework required by investors and lenders.
The proposal is designed to complement rather than replace existing shared ownership. That distinction would allow developers to retain established Section 106 and registered-provider arrangements while potentially using the new model on additional open-market properties where affordability has become a constraint on sales.
Whether the model reaches the construction volumes claimed will depend on decisions still to be made outside the site boundary. Mortgage terms, institutional appetite, National Housing Bank support, and consumer acceptance all have to work before housebuilders can treat the tenure as dependable demand. Until then, 30,000 homes remains a modelled capacity rather than an order book — but one aimed squarely at the commercial bottleneck between planning consent and sustained build-out.
