Rural exception sites: the evidence that unlocks them

A rural exception site affordable housing scheme lives or dies on two documents: a current local housing need survey and a section 106 agreement that a registered provider and their lender will both accept. Policy support exists, landowners are usually willing at the right price, and parish councils are often actively in favour. What stops schemes is evidence that is four years out of date, or occupancy drafting that a lender's solicitor will not lend against.

An exception site is land that would not normally be released for housing, permitted for affordable homes kept in perpetuity for people with a local connection. The exception is to the settlement boundary, not to good design or to the landscape policies of the area.

What an exception site is and where policy allows it

National policy describes exception sites as small sites used for affordable housing in perpetuity, addressing the needs of the local community by accommodating households who are current residents or who have an existing family or employment connection. A proportion of market homes may be allowed at the authority's discretion where that is essential to deliver the affordable units without grant.

Two words carry the weight. Small, which in most adopted policies means something in single figures or low double figures rather than a phase of a strategic site. And perpetuity, which is what the section 106 agreement has to achieve.

Most local plans carry their own exception site policy adding local requirements: a settlement size threshold, a requirement that the site adjoins the settlement boundary, a cap on the number of dwellings, or a requirement for the parish council to support. Read that policy first, because it will be tighter than the national wording.

Note also that the separate First Homes exception site route introduced for market towns and elsewhere operates on a different basis and is not available everywhere. Do not conflate the two in a submission.

Housing need surveys and their shelf life

The need survey is the foundation. A survey covering the parish, ideally carried out by or with a rural housing enabler, establishes how many households in the parish need affordable housing, what size of home they need, what tenure they can afford, and what connection they have to the parish.

Councils treat surveys as having a limited life, and many regard anything much beyond about five years as needing refreshing. Check the authority's own position before you commission or rely on one, because a survey that has aged out is the single most common reason an exception site stalls.

What makes a survey persuasive:

1. A decent response rate, with the distribution method and the number of households contacted stated.
2. Household-level detail on size need and affordability, not just a headline number.
3. Questions that establish the connection to the parish, matching the cascade you intend to draft.
4. A date, an author and a methodology anyone can check.
5. Cross-checking against the housing register for the parish, obtained from the council.

Where the survey shows need for four two-bedroom homes and you are proposing eight three-bedroom homes, the scheme will be refused on its own evidence. Design the mix from the survey rather than from the plot shape.

Local connection criteria and their drafting

The occupancy restriction is what makes it an exception site. It usually runs as a cascade. People who live in the parish come first, then those who work there, then those with close family resident in the parish, then adjoining parishes, and finally the wider district.

Three drafting points decide whether it works.

Define each limb by a period. Residence for at least the last three years, or five out of the last ten, rather than an undefined "lives in the parish". Vague limbs cause disputes at every letting.

Include a release mechanism. If no qualifying household comes forward within a stated period, the home is offered to the next tier and then, after a longer period, more widely. Without that, a home can sit empty because the parish tier produced nobody.

And include a mortgagee exclusion clause. Lenders will not lend against an unrestricted perpetuity covenant, so the agreement must allow a lender in possession to dispose free of the restriction after a defined marketing period. Agree the wording with the registered provider's funder early, not at engrossment.

Tenure mix and the limits of cross-subsidy

Most exception sites are delivered as affordable rent, with some shared ownership where the local incomes support it. In designated protected rural areas, shared ownership leases can restrict a leaseholder from staircasing to full ownership, which preserves the affordable stock but affects how the product is marketed. Check the current model lease and the designation before assuming.

Market housing as cross-subsidy is permitted at the authority's discretion where it is essential to deliver the affordable units. Two things follow.

The proportion has to be justified by an open book appraisal, not asserted. Offering four market homes to fund six affordable ones will be tested, and the test is whether the affordable homes could be delivered with fewer.

And market homes change the character of the application. They attract a different objection profile, they raise the land value expectation, and they can make the parish council less supportive. Some authorities will not accept any.

Landowner expectations and land value

This is the conversation that has to happen first, because it determines whether anything else is worth doing.

An exception site is not worth market residential land value. It is worth something above agricultural value, reflecting the fact that the land will never otherwise be developed, and the uplift is modest. Landowners who have been told what the field next door made for open market housing usually need that explaining carefully.

Where the landowner is a farming family, the exception site sits alongside other options for generating value from the holding, and it is worth setting it in that context rather than in isolation. Our note on farm diversification into workshops and offices covers the alternatives that often come up in the same conversation.

Be straight about the downside too. The land is gone, the covenant is perpetual, and the family will have neighbours.

Section 106 drafting for occupancy control

The agreement does the work that the planning permission cannot. A workable one covers the occupancy cascade with defined qualifying criteria, the tenure of each unit identified by plot, the mortgagee exclusion, restrictions on disposal, a nomination arrangement with the council, the release mechanism, and a mechanism for varying the cascade if the parish boundaries change.

Two practical suggestions. Get the registered provider into the drafting before the application is submitted, because they will have standard requirements and discovering them at the agreement stage adds months. And ask the council for its model exception site agreement at pre-application, since most rural authorities have one and using it avoids weeks of negotiation.

Working with the parish council

Parish support is not a legal requirement in most authorities, but it is close to a practical one, and several local plan policies make it explicit.

Engage before the site is chosen, not after. Parish councils almost always have a view on which field is acceptable, and a scheme on their preferred field with their name attached behaves very differently at committee.

Set the process out in a Planning Statement that ties the need evidence, the site selection and the occupancy control together, and put the numbers in an Affordable Housing Statement with the draft heads of terms attached. Where the site is prominent or lies within a National Landscape, a Landscape and Visual Impact Assessment prepared to the recognised professional methodology carries far more weight than a design statement alone, and councils expect a suitably qualified author with professional review strongly advised.

Illustrative example: a parish of around 400 households with a need survey two years old showing six households in need, four requiring two bedrooms. The scheme is six homes on a field adjoining the village envelope, four two-bedroom and two three-bedroom, all affordable rent, on land bought at a premium over agricultural value. No market housing, a cascade drafted with three-year residence limbs and a six-month release mechanism, and the parish council named as a signatory to the nomination arrangement.
