Grounds for Objection: Valid Reasons to Object to Planning Applications
7 min read
There are plenty of reasons to object to planning applications, and only some of them count. Most objections fail on exactly this point. Not the writing, not the effort, and not whether the concern is reasonable. They fail because the reason given is one the council is not allowed to take into account.
Planning officers call the valid reasons to object material planning considerations. Everything else has to be set aside, no matter how many people raise it or how strongly they feel. Knowing which is which is the difference between an objection the officer has to answer in their report and one they can record as noted.
Valid reasons to object: the grounds that count
Conflict with the local plan
This is the strongest ground there is, and the most underused.
Section 38(6) of the Planning and Compulsory Purchase Act 2004 requires a council to decide an application in accordance with its development plan unless material considerations indicate otherwise. The development plan is your council's adopted local plan. If the proposal breaches a policy in it, the council has to explain why it is granting permission anyway.
Every other ground below is stronger when it is tied to a policy number.
Overlooking and loss of privacy
Whether windows in the new building would look directly into habitable rooms in yours, and how far apart they would be. Most councils have a minimum separation distance in their local plan or a supplementary planning document, often 21 metres between facing windows, though it varies.
Note that a loss of privacy in your garden is usually given less weight than a loss of privacy inside your home.
Loss of light and overshadowing
Whether the proposal would take daylight or sunlight from habitable rooms, or cast your garden into shade. The recognised technical standard is the Building Research Establishment guide BR209, which sets out tests for vertical sky component and annual probable sunlight hours. If the applicant has not submitted a daylight assessment and the geometry looks marginal, ask the council to require one.
Overbearing effect
Distinct from light and privacy. A building can be far enough away not to overlook you and not to take your light, and still be so tall or so close that it dominates the outlook from your home. Officers do weigh this, and it is often described as an oppressive or overbearing impact.
Highway safety, traffic and parking
Whether the access is safe, whether visibility at the junction is adequate, and whether there is enough parking for the number of homes or the floorspace proposed.
Be careful with the traffic argument. The test the council applies is whether the residual cumulative impact on the road network would be severe, which is a high bar. Saying the roads are already busy will not meet it. Attacking the assumptions in the applicant's own transport assessment might.
Parking is more winnable, because most local plans set a numerical standard per bedroom or per square metre. If the scheme provides fewer spaces than the standard, say so and cite the standard.
Design, scale and character
Whether the building is the right size, shape and material for where it is. Poor design is a legitimate reason to refuse planning permission, and has been for some years.
This works best when it is specific. Not that the building is ugly, but that it is three storeys in a street of two, or that it uses render where the prevailing material is brick, or that its plot coverage is far higher than anything around it.
Heritage
If the site is in a conservation area, section 72 of the Planning (Listed Buildings and Conservation Areas) Act 1990 places a statutory duty on the council to pay special attention to preserving or enhancing its character and appearance. If a listed building or its setting is affected, sections 16 and 66 apply. These are duties, not policies, and they carry more weight than a general amenity argument.
You can check whether a site is in a conservation area, or near a listed building, on your council's website or on the government's planning data service.
Trees, wildlife and biodiversity
Whether trees would be lost, whether any are protected by a Tree Preservation Order or by being in a conservation area, and whether protected species use the site. Development in England must also deliver at least a ten per cent biodiversity net gain under the Environment Act 2021.
If protected species are present and the ecological survey is thin or was done at the wrong time of year, that is a serious point.
Flood risk and drainage
Whether the site floods, whether the development would increase flood risk elsewhere, and whether the surface water drainage strategy is adequate. If the site is in flood zone 2 or 3, the sequential test applies, and the council has to be satisfied there is no reasonably available site at lower risk.
Noise, smell, dust and hours of operation
Particularly relevant for commercial, industrial and hot food uses. If the applicant has submitted an acoustic assessment, read its assumptions. They are often more optimistic than the way the site would actually be used.
Loss of open space or community facilities
Playing fields, allotments, public open space, pubs, shops and community buildings all have policy protection, and some have specific tests that must be met before they can be lost.
Reasons that do not count
These get raised constantly, and councils are not permitted to weigh any of them.
Loss of a private view. There is no right to a view in English planning law. This surprises people, and it is the single most common reason an objection is set aside. If your real concern is that a large building will loom over your garden, that is an overbearing impact argument, and it does count. Make it that way.
The effect on your property value. Not a planning matter, at all, ever.
Boundary disputes, covenants and rights of way. These are private legal matters between you and the applicant. A planning permission does not override them, and the council cannot resolve them.
Competition. That the new shop will take trade from yours is not a planning consideration. The vitality of a town centre as a whole can be, but that is a different argument.
Who the applicant is. Their identity, their reputation, their nationality, or the fact that they will make a profit. None of it is relevant and raising it damages your credibility.
Disruption during construction. Noise, dust and lorries during the build are controlled under separate legislation. The most you can do is ask for a construction management plan to be attached as a condition.
Something that already has permission. If part of what you object to was approved previously and that permission is still live, the council cannot revisit it.
That there are already enough houses. Housing need is set through the local plan process, not application by application. If the council cannot demonstrate a five year housing land supply, this argument gets weaker still.
Turning a concern that does not count into one that does
Most people who raise a non-material point have a real planning concern underneath it. It is usually worth finding.
"It will block my view" is often really an overbearing impact, or a design and scale point about a building that is out of proportion with its surroundings.
"It will devalue my house" is often really about loss of light, loss of privacy, or noise. Those are the things that would affect the value, and those are the things that count.
"There is too much traffic already" becomes a real argument if you can point at the trip rates in the applicant's transport assessment and explain why they are understated, or at a junction their own modelling shows over capacity.
"They are only doing it for the money" is never going to work. Drop it.
National policy changed in August 2026
One thing to watch if you are working from a template or an older guide.
The National Planning Policy Framework was restructured in August 2026 and no longer uses paragraph numbers. National policy is now cited by code: GB1 to GB8 for Green Belt, HE1 to HE10 for the historic environment, F1 to F9 for flood risk, N1 to N6 for the natural environment, TR1 to TR8 for transport, DP1 to DP4 for design.
Anything that tells you to cite an NPPF paragraph number is out of date. Using one signals to the case officer that the letter was written against a superseded framework.
Ranking your grounds
Do not give every point equal billing. Lead with whichever has the firmest anchor.
A statutory duty beats a policy. A specific adopted policy beats a general one. A general policy beats an unsupported assertion. If you have a conservation area point and a parking point, lead with the conservation area, because the council has a legal duty there and only a policy on parking.
If one of your grounds is weak, either leave it out or state it briefly and honestly. Padding a letter with everything you can think of does not make it stronger. It buries the argument that might have worked.
If you would rather not go through your council's local plan yourself, we will do it for free. Give us the application reference and we will tell you which grounds you have and how strong each one is, before you decide whether to pay for anything.
