What counts as a material consideration in planning

A material consideration is any matter that relates to the use and development of land and that bears on the planning merits of the proposal in front of the decision maker. That is the whole of the test, and it is wider than most applicants assume. Section 70(2) of the Town and Country Planning Act 1990 requires the local planning authority to have regard to the development plan, so far as material, and to any other material considerations. Section 38(6) of the Planning and Compulsory Purchase Act 2004 then sets the order of operations: determine in accordance with the plan unless material considerations indicate otherwise.

Two questions follow from that, and planning arguments go wrong when they are run together. Is the matter material at all? And if it is, how much weight does it carry? The first is a question of law. The second is for the decision maker.

What makes a consideration material

The courts have set the bar low on materiality. A consideration is capable of being material if it relates to the character of the use of land, serves a planning purpose and is not wholly unrelated to the proposal being decided. That formulation comes from the line of authority running through Stringer v Minister of Housing and Local Government (1970), and it has never been narrowed in a way that helps an objector who wants to talk about something else entirely.

So the gate is wide. A great many things get through it: overlooking, noise, parking stress, highway safety, drainage, trees, heritage impact, the loss of a shop, the design of a dormer. Being through the gate does not mean the point wins. Plenty of material considerations attract almost no weight on the facts of a particular application.

Three practical consequences fall out of this for anyone drafting a statement. Name the consideration in planning terms rather than in the terms the client used. Tie it to a policy or a published standard if one exists. And say what it means for this site, not in general.

The plan led starting point

The development plan is the starting point, not one factor among many. For most sites that means an adopted local plan, any neighbourhood plan covering the area, and in London the London Plan as part of the statutory development plan. Officers write reports in that order because section 38(6) obliges them to.

Where a proposal accords with the plan, the applicant is arguing from the strongest possible position and the objector has to find material considerations that outweigh the plan. Where it conflicts, the burden flips. This is why the age and status of a plan matters so much in practice, and why the evidence about supply and delivery does real work. An authority that cannot show the required supply of deliverable housing sites faces a tilted balance under the National Planning Policy Framework, and the Housing Delivery Test result feeds into the same argument. We look at how that plays out in housing land supply and the Housing Delivery Test.

Policies in the Framework are themselves material considerations rather than part of the development plan. The current edition was published on 17 August 2026 and is organised by policy codes instead of the paragraph numbers used in the December 2023 and December 2024 editions. Quote the edition you are relying on, because a reader with an older copy will not find your reference.

Matters that are routinely material

The familiar list, roughly in the order officers reach for it:

• Development plan policies and any neighbourhood plan policies
• National policy and planning practice guidance
• Design, scale, massing and the relationship to the street
• Residential amenity, meaning overlooking, loss of light, overbearing effect and noise disturbance
• Highway safety, access geometry, parking and servicing
• Flood risk, surface water drainage and foul capacity
• Ecology, protected species, biodiversity net gain and trees
• Heritage significance and the statutory duties under the Planning (Listed Buildings and Conservation Areas) Act 1990
• Contamination, air quality, odour and lighting
• Planning history on the site, including earlier refusals and appeal decisions
• Responses from statutory consultees

Amenity cases usually turn on measurable things, which is why councils publish rules of thumb such as the 45-degree guideline and minimum window to boundary separations. Those guidelines are not policy in themselves, and a well argued departure from one can succeed where the actual effect on the neighbouring room is slight. Our note on measuring the 45-degree line to a neighbour window sets out how the geometry is tested.

Consultee responses carry weight according to their reasoning. Where a consultee relies on published standing advice rather than a site specific view, say so and engage with the advice on its own terms. The distinction matters at appeal and we explain it in standing advice from planning consultees.

Matters that are routinely not material

Private interests that are not planning interests fall outside. Loss of a private view is the classic example. So are devaluation of a neighbouring property, the identity or personal conduct of the applicant, a boundary dispute, a restrictive covenant, rights of light as a civil claim, the Party Wall etc. Act 1996, competition between two businesses, and whether the applicant could have designed something better.

Construction nuisance sits awkwardly. The temporary disturbance of building work is generally controlled through other regimes, yet the management of construction traffic and hours is routinely conditioned, so the point is better framed as a request for a construction management plan than as an objection in principle.

Moral objections, the number of objectors and the volume of a petition are also not material in themselves. Weight attaches to the planning content of what objectors say, not to the headcount. That is a hard message to deliver at a parish meeting and it is still correct.

Weight is a separate question from materiality

Once a matter is in, the decision maker decides how much it counts for. Weight is only challengeable on the usual public law grounds, which is why so few decisions fall over on this ground alone. A court will intervene where a decision maker ignored a material consideration altogether, took an immaterial one into account, or reached a conclusion no reasonable authority could reach. The route for that challenge is set out in section 288 and judicial review.

Practical markers that raise weight: a policy that is up to date and directly on point, a published standard with a measured result against it, a statutory duty, and site specific evidence from a survey. Markers that lower it: an emerging policy not yet examined, an appeal decision on a different site and different facts, generalised assertion, and anything the authority has itself departed from recently.

An illustrative example on a householder application

Take a two storey rear extension on a semi detached house in a 1930s suburb, 3.2 m deep, with a neighbour's kitchen window 1.8 m from the shared boundary. This example is illustrative.

The neighbour objects on four grounds: loss of light to the kitchen, loss of a view over the garden, the extension will reduce the value of their house, and the applicant extended a previous property without permission.

Grounds one is material and measurable. The officer applies the authority's 45-degree guideline in plan and section, and if the line is broken, asks how much light the kitchen actually loses and whether it is a habitable room served by other windows. Ground two is not material. Ground three is not material. Ground four is not material to this application, although any enforcement history on this site would be.

A good response to that objection does not argue about all four. It concedes nothing on the first and answers it with a drawing, a daylight calculation if the loss is marginal, and an offer to reduce the depth by 400 mm if that clears the line.

Putting a material point in front of the case officer

Write the planning label first, then the evidence, then the consequence for the decision. One page per point beats ten pages of narrative. Where a supporting document is the right vehicle, use it: amenity arguments belong in a Design and Access Statement or a daylight assessment, policy arguments in a Planning Statement, and heritage arguments in a Heritage Statement. The full set of supporting documents sits on the planning report index, which also shows which reports a given constraint tends to trigger.

If a consideration is finely balanced, say so and explain why your side of the balance should win. Officers are more persuaded by an applicant who concedes the one weak point than by one who claims there is no harm anywhere.
