A draft planning document proposes that sites of 15 homes or more contribute 30% affordable housing, while smaller schemes face a new cash contribution formula for the first time.
A Gap in the Rules, Finally Filled
There’s a quietly damning detail buried in Dover District Council’s new draft housing document: the council’s existing affordable housing guidance dates back to 2007. And it never applied its financial contribution formula to smaller developments at all. That gap meant schemes of fewer than 15 homes could slip through without contributing a penny toward affordable housing. The new draft Supplementary Planning Document — now out for public consultation — is designed to close it.
What the Draft Actually Proposes
The document sets out two distinct tracks depending on the size of a development. For sites of 15 or more dwellings, the council wants 30% affordable housing, delivered on site. Straightforward enough.
For smaller schemes — those between 5 and 14 homes — the approach is more flexible. Developers may be asked to provide affordable homes on site, pay a financial contribution, or a combination of both. The proposed contribution is pegged at 5% of total gross development value. The document’s own worked example puts that at £98,275.
Payment would fall due on commencement of development. Not at completion, not on sale. At the start.
The Viability Question
The council hasn’t ignored commercial reality. The draft acknowledges that affordability levels and any financial contribution will be judged against economic viability, taking into account individual site conditions and market circumstances — which is a meaningful caveat. It means the 30% target and the 5% GDV formula are starting points, not hard floors, and a developer who can demonstrate genuine financial pressure can negotiate.
And that cuts both ways. For developers working on tighter margins, it offers some reassurance. But for housing campaigners hoping for firm, non-negotiable commitments, it leaves the door rather ajar.
Where Dover Fits in the Wider Kent Picture
Dover isn’t alone in reaching for this kind of document. Other Kent districts — Ashford and the former Shepway area, now Folkestone and Hythe — have used similar supplementary planning documents to spell out how their affordable housing policies work in practice. An SPD doesn’t alter the legal weight of the development plan itself, but it gives a council a clearer, more consistent footing when negotiating with developers.
What’s notable here is the attention to smaller sites. Most of the planning debate around affordable housing circles the big strategic allocations — the garden villages, the urban extensions. But Dover gets a lot of its housing delivered in smaller parcels: a dozen homes here, eight there. Scrappy, piecemeal stuff that’s easy to overlook. Capturing contributions from those schemes matters more than it might first appear.
The consultation closes on 14 May 2026.

- Developments of 15 or more homes would be expected to provide 30% affordable housing on site

What This Means for Kent Residents
If you’re on a housing waiting list in the Dover district — or simply struggling with rents and prices in the area — this is one of the mechanisms that determines whether new developments include homes you might actually be able to afford. The consultation is open to the public, so residents, community groups, and local businesses can all have their say before the 14 May 2026 deadline. Dover District Council’s website carries the full draft document and details on how to respond.
