Someone reported me to planning enforcement: what happens now

 

A letter from the council’s planning enforcement team is frightening. It arrives out of the blue, it uses words you have never had to think about before, and it can read as though something has already been decided about you. It has not been.

Being reported to planning enforcement is the start of a process, not the end of one, and most reports never turn into formal action at all. The council has a choice about whether to act, and national policy tells it to use that choice proportionately.

This page explains what happens next, in the order it really happens: what the council can ask you, what you must answer, how long it takes, the one mistake that costs people most, and what to do in the first few days. It sits inside our wider guide to planning enforcement.

If you are looking at this from the other side, and it is you who thinks a neighbour has built something without permission, our guide on how to report a breach of planning control explains what the council can and cannot do about it.

Whilst we are happy to give you some help via this page, it is often easier to consult a professional. If in doubt – STOP – and reach out to us. We are here to help. Contact us here. 

 

 

A complaint is not a finding

 

Anyone can report anything to a council. A neighbour, a passer-by, a parish council, or a competitor. The council does not have to agree with them, and it will not usually tell you who it was. What it does have to do is look into it.

That is all that has happened so far. Nobody has decided you have done anything wrong. Very often the answer turns out to be that you never needed permission at all, because the work was already allowed under permitted development rights.

 

Most reports do not lead to enforcement action

 

This is the part people find hardest to believe. Even if the council agrees a breach has happened, it does not have to do anything about it. It acts only where it thinks acting is worthwhile, which the law calls being expedient. It is a choice, not a duty, and a great many reports end quietly at exactly this point.

What the council weighs up when it makes that choice, the national policy behind it, the guidance on when it should leave a breach alone, and the local enforcement plan that sets its priorities, are all set out on our planning enforcement home page.

 

Check what the letter is actually complaining about, because one type is not like the others. If the council is objecting to the state of your land rather than to anything you have built or changed, you may be looking at a section 215 notice instead. That runs on a different track, with a much tighter deadline: the appeal goes to the magistrates’ court, not to a planning inspector, and it has to be lodged before the notice takes effect.

 

The letter, and what you actually have to answer

 

Most cases start with an informal letter, an email or a phone call, and there is no legal duty attached to any of those. Replying politely and factually is almost always better than silence, because a case that can be explained early often closes early.

Two letters do carry legal weight:

• a planning contravention notice, which asks questions about what is happening on the land and gives you 21 days. Not returning it, or answering falsely, is a criminal offence
• a section 330 notice, which asks who owns the land and who else has an interest in it, and gives you at least 21 days

Neither of those is the council taking enforcement action. Neither goes on a public register, and neither is a charge against your property. But what you write is evidence in your own words, and it can be used later, so if anything significant is at stake take advice before you reply rather than after.

 

If someone turns up at the door

 

Officers can enter land to find out whether there has been a breach, but there are limits. If it is your home, they cannot demand entry unless they have given you 24 hours’ notice, or a magistrate has issued a warrant. You can politely offer a time that suits you instead.

There is nothing to gain from being obstructive, and obstructing an officer who does have the right to be there is itself an offence. There is equally nothing wrong with asking for identification, asking what the visit is about, and asking for the request in writing.

Our guide to how a planning enforcement investigation works sets the entry powers out in full: what the officer has to show you if you ask, when a magistrate can issue a warrant and how narrow it is, the duty to leave your gate as they found it, and your right to compensation if something gets damaged.

 

Do not rush into a retrospective application

 

The instinct is to apply straight away and make it go away. Sometimes that is right. Often it is expensive, and it can cost you your best card.

Check first whether you needed permission at all. If the work was permitted development there is nothing to put right, and a certificate of lawfulness is the cleaner answer. If the work or the use is old enough to be beyond the time limits, a certificate for an existing use does the same job.

Then understand that applying after the event can affect a later enforcement appeal. You can apply for retrospective permission, or a later enforcement notice may carry ground (a), asking for permission through the appeal, but the availability of ground (a) depends on the sequence and dates. In England, for an enforcement notice issued on or after 25 April 2024, ground (a) is barred where the notice was issued after the related retrospective application was made and within two years after that application ceased to be under consideration. The council can also refuse to deal with an application at all once a notice has been issued. Our guide to retrospective planning permission explains how that choice works.

And if your area charges the community infrastructure levy, permission granted after the event loses any relief or exemption you had been given, apart from the exemption for minor development. For a self builder that can be a very large bill arriving because of a very small piece of paperwork.

 

How long does all this take?

 

Longer than you expect. Months rather than days is normal, and councils have far more reports than officers. Many files are closed quietly without much being said, so it is worth asking in writing for confirmation once you think a case is over.

Time also runs in your favour. In England the council generally has ten years from the breach, and four years where building work was substantially finished, or a change to a single home happened, before 25 April 2024. Our page on enforcement time limits sets both out in full.

 

If the council does act, when can you appeal?

 

The first formal step is usually an enforcement notice, and that is the point at which a right of appeal appears. The deadline is strict: your appeal has to be made before the date the notice says it takes effect, and there is no discretion to extend it.

There is no appeal against being investigated, against a planning contravention notice, against a section 330 notice, against an enforcement warning notice inviting you to apply, or against a breach of condition notice, which is the one that catches most people out. The only route against any of those is the High Court, which is slow and expensive. Our guide to planning appeals covers the ordinary routes.

 

Is there a cost?

 

Nothing is charged for being reported, and nothing is charged for answering the council’s questions. Costs arise in three other ways: any application you make to put things right, which is charged at the normal rate for that type of application and is set out in our guide to planning application fees; professional advice; and the cost of undoing work if it comes to that.

At appeal each side normally pays its own way, although an award of costs can be made where someone has behaved unreasonably.

 

Reported to planning enforcement: what to do this week

 

• write down what you built or changed and when, with anything that proves the dates
• gather your permissions, plans, invoices, delivery notes and dated photographs
• check whether it was permitted development before assuming that it was not
• answer any formal notice inside its deadline, and reply politely to informal letters
• ask the council in writing what exactly it says the breach is
• take advice before you reply, not after, if the sums involved are significant

If one of these letters has landed and you are not sure what to do next, you can reach us via here to help.
