Refusal on housing land supply and the tilted balance

A refusal that turns on housing land supply is an argument about weight, not about merit. If the council cannot demonstrate a five year supply of deliverable housing sites, the presumption in favour of sustainable development is engaged, the policies most important for determining the application are treated as out of date, and permission should be granted unless the adverse impacts would significantly and demonstrably outweigh the benefits. That last formulation is the whole appeal.

One point of housekeeping first. The current National Planning Policy Framework was published on 17 August 2026 and replaced the paragraph numbering of earlier editions with policy codes, so the presumption that practitioners knew as paragraph 11(d) in the December 2024 edition now carries a different reference. Check the live Framework on gov.uk for the current code before citing it in a statement of case, because an inspector will notice a reference taken from an old copy.

What engages the presumption

Three routes get you there and they are not interchangeable.

The first is an absence of a five year supply of deliverable housing sites, measured against the local housing need figure produced by the standard method, with the buffer the Framework requires added on top.

The second is delivery rather than supply. Where the Housing Delivery Test measurement shows that net additional dwellings over the preceding three years fell below the lower threshold, the presumption applies as a consequence of the result itself. Intermediate thresholds require an action plan and a larger buffer without engaging the presumption, so the exact percentage matters.

The third is an absent, silent or out of date development plan, which is a separate proposition and the hardest of the three to run, because councils resist it and inspectors treat a recently adopted plan as a complete answer.

Establish which route you are on in the first page of your statement. Appeals get lost because the appellant argues supply while the council answers on delivery, and the inspector has to sort out which case is being made.

The supply evidence and how it is tested

Supply is a number built from a schedule of sites, and the argument is always about the schedule.

The council publishes a position, usually in an annual monitoring report or a dedicated five year supply statement. Your task is to work through it site by site. Four categories do most of the work:

1. Sites with detailed planning permission, which the Framework treats as deliverable unless there is clear evidence that homes will not be delivered within five years.
2. Sites with outline permission or an allocation, which need clear evidence of delivery within five years to count.
3. Windfall allowances, which require a justified rate based on historic evidence rather than an aspiration.
4. Large sites with long lead-in times, where the delivery trajectory assumed by the council is frequently optimistic on first completions.

The strongest material is specific and dull: a site with permission granted four years ago where no reserved matters have been submitted, a strategic site where the spine road has no highway agreement, an allocation with a single owner who has not marketed the land. Named sites with documented facts move the number. General complaints about optimism do not.

Where the shortfall is modest, remember that the question is binary for the purposes of engaging the presumption. A supply of 4.8 years engages it as surely as one of 3.2 years, though the scale of the shortfall feeds into the weight given to the housing benefit afterwards.

Deliverability disputes over named sites

The definition of deliverable in the Framework glossary is where these appeals are won and lost, and it operates as a shifting burden.

For a site with detailed permission, the burden sits with the appellant to produce clear evidence that delivery will not happen. For a site with outline permission or an allocation, the burden sits with the council to produce clear evidence that it will. Getting that direction right changes which sites are worth attacking.

Useful evidence includes the planning history of the site, correspondence with the landowner or promoter where it exists, published build-out rates for comparable sites in the authority, the absence of discharged pre-commencement conditions, and the state of any required infrastructure. Evidence that does not help includes assertions about market conditions and the appellant's own opinion about what a housebuilder would do.

Expect the council to produce updated figures shortly before the appeal, often with sites added. That is normal rather than sharp practice, since supply moves. Ask for the schedule in a workable format early, and agree what you can in a statement of common ground so that the hearing time goes on the sites in dispute.

What the balance does to the weight of policies

The presumption does not disapply the development plan. It changes the weight given to the policies most important for determining the application, which is a narrower proposition than councils sometimes concede and than appellants sometimes claim.

Two consequences follow. A policy restricting development outside a settlement boundary, where the boundary was drawn to deliver a housing requirement that is now out of date, loses much of its force. A policy protecting a designated heritage asset or a landscape designation does not, because its purpose is unrelated to housing supply.

So the first analytical task is to identify which policies are the ones most important for determining the application and to say why each is or is not out of date. A statement that treats the whole plan as out of date overreaches and invites the inspector to disregard the submission. Read the refusal notice closely to see which policies the council actually relied on, using the approach in reading a refusal notice and turning it into a plan, and address those.

Harm that still outweighs the presumption

The tilted balance is not a permission. Inspectors dismiss appeals under it regularly, and the pattern of those dismissals is worth knowing.

Harm that has defeated the presumption includes substantial landscape harm in a valued landscape, harm to the setting of a listed building where the statutory duty applies, highway safety where the access cannot be made adequate, and conflict with a recently made neighbourhood plan carrying full weight. Where the Framework's protections for particular areas and assets apply, including habitats sites, land in the functional floodplain, Green Belt and designated heritage assets, the presumption does not operate in the same way, and the specific policy test for that designation has to be met on its own terms first.

The honest reading is that the presumption helps most where the harm is a policy conflict rather than a physical effect. A scheme outside a settlement boundary with no other objection is the classic winner. A scheme outside a settlement boundary that also sits on a prominent ridge is not, and the supply argument will not rescue it.

That is also why the benefits side of the balance deserves real work rather than a list. Quantify the housing numbers including affordable units, the local economic effects, any infrastructure delivered, and the biodiversity position. A Planning Statement that sets the benefits out with figures gives the inspector something to weigh against the harm, and the same discipline answers other policy-based refusals such as the loss of employment land.

Preparing supply evidence for an inquiry

Where supply is the central issue, the appeal usually proceeds by inquiry and the supply evidence is handled in a dedicated session.

Four things make that session go well. A site schedule in a spreadsheet agreed as to format, with each disputed site numbered and the dispute summarised in a line. A statement of common ground recording the agreed requirement figure, the agreed buffer and the sites not in dispute. A proof of evidence from a witness who can speak to delivery rather than only to policy. And a clear statement of the arithmetic, so the inspector can see what happens to the total as each disputed site falls in or out.

Keep the number of disputed sites manageable. An appellant disputing 40 sites looks like someone with no particular case. One disputing six, with documented facts on each, looks like someone who has done the work.

Objectors and Rule 6 parties often participate in these sessions, and their role is set out in what objectors can do once a planning appeal starts.

Where the argument has stopped working

Three situations have blunted this argument in recent years.

A council that has just adopted a plan with a trajectory tested at examination is difficult to challenge in the first year or two afterwards. An authority that can demonstrate supply by a comfortable margin shifts the appeal back onto the merits, where a scheme that was marginal on design or landscape grounds usually fails. And an appellant who relies on the presumption instead of making a positive case tends to lose, because inspectors still carry out the balance and they need benefits to put in it.

One uncertainty worth stating plainly. The standard method, the buffer arrangements and the Housing Delivery Test consequences have each been changed more than once in the last few years, and they are capable of changing again.
