How to object to a neighbour's planning application

An objection to a planning application counts when it is about something the council is allowed to take into account, ties that concern to a policy in the adopted local plan, and gives the case officer evidence they can put in the report. Everything else, however strongly felt, gets summarised in one line as "objections received" and has no effect on the decision. So the useful question is not how to object to a planning application but which of your concerns are material and how to evidence them.

You usually have about three weeks. Start by finding the closing date.

The consultation period and how you find out at all

Article 15 of the Town and Country Planning (Development Management Procedure) (England) Order 2015 sets the minimum publicity a council must give. In practice that means a letter to adjoining occupiers, a site notice on a lamp post or the site frontage, and for larger or more sensitive schemes a notice in the local press. The representation period runs from the date of the notice, and 21 days is the common figure.

Neighbour letters go to properties that adjoin the site. If your house is across the road, or backs onto the site diagonally, you may get nothing, which is why the site notice matters and why it is worth checking your council's weekly list of new applications if a site near you is being marketed.

Late representations are usually still read if they arrive before the decision is issued. Usually is not a plan. Write inside the period.

What the council can and cannot take into account

Material considerations are the things that bear on the use and development of land. The list that comes up in householder and small-scale cases is short enough to keep in your head:

• conflict with policies in the adopted development plan and with the National Planning Policy Framework
• overlooking and loss of privacy, particularly habitable room to habitable room
• loss of daylight or sunlight, and overshadowing of a garden
• an overbearing effect from bulk and proximity
• design, scale, massing and materials in their context
• highway safety, access visibility and parking pressure where the council has adopted standards
• harm to a listed building, a conservation area or the setting of either
• loss of trees, including trees protected by a Tree Preservation Order
• noise, odour, light spill and hours of operation for anything non-residential
• flood risk, drainage and contamination
• the planning history of the site, including previous refusals and appeal decisions

What officers must set aside is just as short. Loss of a private view. The effect on your property value. Boundary disputes, restrictive covenants and rights of way, which are private legal matters. Competition with an existing business. The identity, nationality or motives of the applicant. Matters controlled by other regimes, such as the Party Wall etc. Act 1996 or the Building Regulations. Construction noise and disruption, which is temporary and dealt with under environmental health powers rather than by refusing permission.

Objections built on those points are not rude or wrong. They are simply outside the decision, and including them dilutes the parts of your letter that are inside it.

Structuring an objection an officer can use

Write it as if the officer will paste your headings into their report, because in effect they will.

1. Put the application reference, the site address and your own address at the top. An objection from an unidentified sender carries less weight and may not be published.
2. State in one sentence what you are asking for: refusal, or approval subject to a named condition. Objectors often want the second and ask for the first.
3. Take one concern per numbered paragraph. Name the policy it engages, using the policy number from the adopted local plan.
4. Give the evidence. A dimension from the submitted drawings, a photograph from your own window with the date, a measurement of the gap between the proposed flank wall and your boundary.
5. Say what would fix it, where something would. Officers have far more room to negotiate a change than to refuse outright.

Numbers persuade. "The proposed two-storey flank wall will be 3.2 m from my kitchen window, which is the only window serving that room" is an argument. "It will be overbearing" is a description of your feelings about the argument.

Turning the council's own documents against a weak scheme

The strongest objections quote the council back to itself. Most authorities have adopted a householder design guide or a residential extensions supplementary planning document, and those documents contain the 45-degree tests, the separation distances between facing windows, and the rules on subordinate roof forms that officers apply every week. Finding the paragraph that the scheme breaches is worth more than any amount of adjectival objection, and the design guide SPDs that officers check line by line are published on the council's own website.

The same goes for parking. Where a council has adopted standards, an application providing fewer spaces than the standard requires has to justify the shortfall, and the way to test that is against the council's own parking standards SPD rather than against your sense of how busy the street is.

In a conservation area, the character appraisal and management plan is the document to read. It will describe the prevailing plot rhythm, boundary treatments and materials, and it is the evidence base for any harm argument. Some areas also carry an Article 4 direction that has removed permitted development rights, which occasionally means the works being applied for are more extensive than the applicant realises.

Asking for the application to go to committee

Where the case is finely balanced, the difference between a delegated decision and a committee one can be the difference between refusal and approval. Committee referral is governed by the council's scheme of delegation, published inside its constitution.

The routes are a threshold number of objections, which some councils count per household rather than per letter, and a written request from a ward councillor giving planning reasons. Contact your ward councillor early, before the end of the consultation period, and give them the planning reasons in a form they can forward. A councillor who has to invent the reasons themselves may not bother.

If the application reaches committee, register to speak. Deadlines are typically a working day or two before the meeting and speaking time is usually three minutes.

After the decision

There is no third-party right of appeal in England. If permission is granted, you cannot appeal it. The applicant can appeal a refusal, and if they do you will be notified and can send your representations to the Planning Inspectorate, which considers written representations from interested parties.

Two other routes exist and both are narrow. Judicial review challenges the lawfulness of the decision rather than its merits, must be brought promptly and in any event within six weeks in planning cases, and needs legal advice before you spend anything. A complaint to the Local Government and Social Care Ombudsman covers maladministration in how the council handled the application, not the outcome.

The more productive thing to do after an approval is to read the conditions. Conditions on hours of construction, obscure glazing, boundary treatment, landscaping and the removal of permitted development rights are enforceable, and breaches are reported to the council's enforcement team. Illustrative example: a two-storey side extension approved with a condition requiring the first-floor flank window to be obscure glazed and fixed shut. If clear glass goes in, that is a breach of condition and the council can serve a breach of condition notice.

Keep a copy of the approved drawings. Most enforcement complaints from neighbours fail because nobody can show what was actually permitted.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
