Reading a decision notice as a neighbour

To understand planning decision notice wording, start with the fact that this document, and not the officer report or anything said at committee, is the enforceable record of what was permitted. It names the permission, lists the drawings the development must be built in accordance with, sets out the conditions and gives the reasons for them.

If a builder next door is doing something you did not expect, the decision notice and the drawings it lists are where you check whether it is allowed.

Where to find the decision notice

Every council publishes its planning register online, searchable by address or by application reference. Find the application, then look for the document usually labelled decision notice or decision, dated on or after the determination date.

Download it, and download every drawing it mentions. Councils reorganise their document lists, and links break. A copy in your own folder, with the date you downloaded it, is worth having.

The officer report is a separate document and you should read it too, because it explains the reasoning and records how objections were dealt with. It has no legal force of its own. Where the report and the decision notice differ, the decision notice governs.

The approved plans list and why it matters

Almost every permission carries a condition requiring the development to be carried out in accordance with a list of approved drawings, each identified by number and revision.

That condition is the most useful thing on the notice. It converts a general permission into a precise one: this footprint, this height, these window positions, this boundary treatment. A development that departs from the approved drawings is a breach of that condition, whatever else the permission says.

So check the revision numbers. A drawing numbered 101 revision C is not the same as revision A, and the version on the register that you looked at during the consultation may not be the version approved. If what is being built looks different from the drawing you objected to, compare it against the listed revision before concluding anything.

Where the scheme was changed during the application, the earlier drawings usually remain on the register, which is a common source of confusion. Only the listed ones count. The related question of what happens when plans are amended after you object explains how those changes are handled.

Reading conditions that protect you

Conditions do the practical work of protecting neighbours, and they fall into recognisable groups.

Two words change everything in these conditions. A condition requiring something before development begins has to be discharged before any work starts on site. A condition requiring something before first occupation can be left until much later. Check which you are relying on.

Also look for conditions requiring details to be approved and then retained or maintained. A screen fence secured by a condition that says retained thereafter is a permanent obligation. One that only requires it to be erected before occupation may be removed the following year.

Informatives and their status

After the conditions, most notices carry a section of informatives, sometimes called notes to the applicant. These are advisory and they are not enforceable.

They typically remind the applicant about building regulations, party wall procedures, protected species, highway licences for scaffolding, or the need to consult a water undertaker. Useful information, no legal effect through the planning permission.

Do not rely on an informative as protection. If something matters to you and it appears only as an informative, that is worth raising with the case officer before the decision is issued, because it can sometimes be converted into a condition where the tests for conditions are met.

Checking the reasons given

Every condition must be accompanied by a reason, and reading them tells you what the council thought it was achieving.

The reasons matter later. If you complain that an obscure glazing condition is being ignored, the reason attached to it, typically protecting the privacy of a named neighbouring property, is what establishes that your interests were within the condition's purpose. It also helps if the applicant later applies to vary or remove the condition, because the council has to consider whether the original reason still applies.

The notice will also give reasons for the grant, usually a short statement of the policies relied on, and reasons for refusal where permission is refused. Read refusal reasons closely, because a resubmission that does not address each one is unlikely to succeed and you can say so in a representation. The approach set out in objecting to a retrospective planning application applies in much the same way where works have already started.

What to do if a condition is breached later

Enforcement is discretionary and evidence-led, so the quality of your report determines what happens.

1. Identify the specific condition number and quote it. A complaint about a condition number is processed differently from a complaint about a nuisance.
2. Photograph what is happening, with dates, from a position you can describe.
3. Compare against the approved drawing and note the difference, with measurements where you can take them safely from your own land.
4. Report it to the council's planning enforcement team in writing, and ask for a case reference.
5. Keep a log and quote the reference in each subsequent report.
6. Ask what the council has decided and, if it decides not to act, ask for the reason in writing.

Where a condition is breached, the council can serve a breach of condition notice, which carries no right of appeal. It can also invite a retrospective application, which is often what happens, and you get a fresh opportunity to comment.

Immunity periods for enforcement were changed by the Levelling-up and Regeneration Act 2023, so do not rely on older summaries of the four year and ten year rules. Ask the council what period applies to the breach you are reporting.

Time limits on the permission

A full planning permission normally has to be begun within three years of the date of the decision, and the condition on the notice will say so. Outline permissions work differently, with a period for submitting reserved matters and a further period for beginning the development.

Beginning means a material operation, which can be quite modest: digging a trench for a foundation, laying out a road. A permission lawfully begun does not expire, which is why a site can sit untouched for years after a token start.

Check the date on the notice and diary it. If the three years pass with nothing done, the permission lapses and any new proposal needs a fresh application, assessed against whatever policy applies then rather than the policy that applied when the original permission was granted.

This is general guidance rather than legal advice, so check the position with your local planning authority before relying on it.
