Objecting to a scheme on an allocated site

If the field at the end of your road is allocated for housing in the adopted local plan, an objection saying the site should not be developed will be read, logged and set aside. The allocation already decided that question, through a plan-making process with its own consultation stages and an independent examination. Section 38(6) of the Planning and Compulsory Purchase Act 2004 requires applications to be determined in accordance with the development plan unless material considerations indicate otherwise, and an allocation is part of that plan.

That is not the end of the matter. An allocation settles the principle and leaves a great deal open, and the objections that change schemes on allocated sites are the ones aimed at what the allocation left open.

What an allocation settles and what it leaves open

An allocation does three things. It identifies a defined area of land. It states the use or uses the plan expects there. And it usually attaches requirements that development must satisfy.

What it does not do is approve a layout, a density, a house type, an access arrangement, a drainage strategy or a phasing plan. None of those existed when the plan was examined. The application is the first time anyone sees them, and they are where the planning judgement now sits.

So the practical move for an objector is to separate the two. Read the allocation policy, write down what it commits to, and then treat everything else as open. An objection organised that way reads as informed rather than as opposition in principle, and officers and committee members respond to it differently.

Why the principle of development is rarely arguable

The reason is procedural rather than political. An allocation reaches the adopted plan through a sequence: evidence gathering, a call for sites, a sustainability appraisal, draft consultation, publication consultation under Regulation 19, submission for examination, hearing sessions before an inspector appointed by the Planning Inspectorate, main modifications, and adoption by the authority.

By the time a planning application arrives, every one of those stages has closed. Arguments about whether the land should have been allocated, whether the housing requirement was too high, or whether a different site would have been better were arguments for the examination.

There are narrow exceptions, and they are narrow:

• the plan is old enough that specific policies have been superseded by national policy or by changed circumstances
• the allocation was made on an assumption that has since been shown to be factually wrong, for example an access that the highway authority has since confirmed cannot be delivered
• a constraint has arisen since adoption, such as a new designation, a protected species record, or a catchment-wide nutrient or water neutrality requirement
• the proposal is materially different from what the allocation contemplated, for example a different use or a scale well beyond the indicative capacity

Outside those, the principle is settled. Saying so in your own objection costs you nothing and buys you credibility for the points that follow.

Site specific requirements in the allocation policy

This is the most productive part of an allocation for an objector, and it is routinely ignored.

Allocation policies in modern local plans carry a list of requirements. The wording varies but the content is familiar: retention of a hedgerow or tree belt, a landscape buffer of a stated depth to a particular boundary, vehicular access from a specified road, a pedestrian or cycle link to a named destination, on-site open space of a stated quantum, a drainage solution that addresses an identified surface water issue, archaeological evaluation, a specified proportion of affordable housing, contributions towards a school or health facility.

Each requirement is a test the application has to pass. Work through them one at a time against the submitted drawings and documents, and state for each whether the application meets it, partly meets it, or does not address it.

That exercise is more effective than any general objection, for two reasons. It engages the development plan on its own terms, which is what section 38(6) requires the decision maker to do. And it is checkable: an officer can look at the drawing and see whether the 15 metre buffer is 15 metres or eight.

Capacity figures and whether they are a ceiling

Allocations usually state a number of dwellings or an area of floorspace. Whether that number is a cap depends entirely on the wording.

Where the figure is indicative and the application exceeds it, the argument is not that the number has been breached. It is that the extra units can only be accommodated by failing one of the allocation's own requirements: the buffer has been eroded, the open space has shrunk, the trees have gone, the parking standard has been undercut. Make the link explicit, because a bare complaint about numbers will be answered by pointing at the word "approximately".

Objections that still carry weight on an allocated site

The material considerations that remain fully live are the ones about the scheme rather than the site.

Layout and design, measured against the authority's design guidance, any design code, the National Design Guide and the plan's own design policies. Highway safety and the capacity of the specific access junction, which is a matter for the highway authority's technical assessment and can be challenged with evidence. Amenity of existing neighbouring properties, including overlooking, overshadowing and noise, assessed against the authority's separation standards. Surface water and foul drainage, where the lead local flood authority and the sewerage undertaker are consultees. Ecology, including the biodiversity net gain requirement and any protected species present. Trees, where a tree belt or individual specimens are protected. Heritage, where a listed building, a conservation area or archaeology is affected. Open space provision and its quality, location and future management. The adequacy of the section 106 package against the authority's own published contribution requirements.

A good objection on an allocated site reads like a critique by a planning officer: policy reference, what the policy requires, what the application shows, the gap between them, and the change that would close it.

Ask for conditions as well as refusal. Objectors who propose a condition, such as a construction management plan with routeing, a landscape maintenance period, or a restriction on working hours, often get it, and that is a real outcome.

Evidence that the allocation assumptions were wrong

Occasionally the stronger argument is that something has changed since the plan was adopted. This is a factual argument and it needs evidence rather than assertion.

The versions that work in practice: a protected species record postdating the plan's evidence base, obtained from the local environmental records centre. A surface water flooding history on the site that the plan's level 1 assessment did not pick up, evidenced by the authority's own records or by dated photographs. A catchment-wide requirement such as nutrient neutrality, imposed by the statutory nature conservation body after adoption. Or a highway authority position that has changed since the plan evidence was prepared.

Where you have that evidence, present it as an addition to the evidence base rather than as a challenge to the plan. Officers can act on new facts. They cannot reopen the examination.

Engaging at local plan stage instead

The lesson most communities draw too late is that the decisive consultation happened before the application. If you want to influence whether land is allocated at all, the stages to engage with are the call for sites, the draft plan consultation, and above all the Regulation 19 publication stage, because representations made then are the ones the inspector considers at examination, and only people who made them can appear at the hearing sessions.

Most authorities also maintain a local development scheme setting out the timetable for plan review, and a five-year review cycle is the normal expectation. Sign up to the planning policy mailing list rather than the application alerts.

For the current application, the practical steps are: get the allocation policy wording, list its requirements, check each against the submitted documents, put the gaps in a short written representation with policy references, send it within the consultation period, and ask the ward councillor whether the application will go to committee. Where the scheme is large enough for the developer to have carried out its own consultation, the Statement of Community Involvement submitted with the application repays reading, because it records what the developer says it was told and sometimes shows where it changed the scheme in response. The report index explains the other documents in the submission, and related reading includes reading a decision notice as a neighbour and how to get involved in a neighbourhood plan.
