How to report a breach of planning control

 

Something has gone up next door and you are fairly sure nobody asked permission. Or a quiet yard has turned into a business, and the lorries start at six in the morning. You want to know who to tell, and what happens after you tell them.

This page explains how to report a breach of planning control in England, and it is honest about the limits. The council is the only body that can act. It does not have to act. It will not keep you updated the way you might expect, and if it decides to do nothing there is nobody you can appeal to.

None of that means reporting is pointless. It means the useful work happens before you send anything, and the single most useful step takes ten minutes and costs nothing: find out whether permission was needed at all. A great many reports turn out to be about work that was always allowed. This page sits inside our wider guide to planning enforcement.

If you have landed here because somebody has reported you, the page you want is someone reported me to planning enforcement.

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. 

 

 

Start by checking whether permission was needed

 

This is the step almost everybody skips, and it is the one that matters most. A lot of building work needs no planning permission because it is already allowed by national rules, known as permitted development rights. Extensions within certain sizes, most garden outbuildings, many fences, loft conversions and a great deal else can all be built without anybody applying for anything.

The scale of this is not small. Cornwall Council publishes that historically around 40% of the reports it received turned out not to be a breach of planning control at all.

Some things are not planning matters in the first place, and reporting them to the planning department only delays you finding the right department. These include:

• boundary disputes, deeds, covenants and rights of way
• party wall issues, which have their own separate procedure
• building safety and structural standards, which are building regulations, not planning
• noise, smells and rubbish, which are usually environmental health
• parking on the street, and most highway obstructions
• a neighbour’s trees, unless they are protected or in a conservation area

 

One thing is worth ruling out before you go any further. If what bothers you is the state of a place rather than something that has been built or changed, it is not a breach of planning control at all. Rubbish, dereliction and a badly neglected frontage are handled under a separate power, and our page on the section 215 notice explains how to raise it and what the council can make an owner do.

 

How to use the planning register

 

Every council keeps a public planning register for its area. It is free, it is online, and you can search it by address. Look up the property and you should find any application, the plans that went with it, the decision notice, and the conditions attached to any permission.

Read the conditions properly, because this is where a lot of genuine breaches live. Development can have full permission and still be in breach if a condition is being ignored, for example a condition limiting opening hours, requiring a screen of planting, or restricting what the building can be used for.

There is a second register worth checking, which lists formal enforcement action already taken: enforcement notices, stop notices, breach of condition notices, planning enforcement orders and enforcement warning notices. If the council has already served something, it will be on there, and your report would be telling it what it already knows.

 

What evidence actually helps

 

Enforcement officers are dealing with far more cases than they have hours. A report that answers the obvious questions gets triaged faster than one that does not. Useful things to include:

• the address, and exactly what you can see, described plainly
• when it started, and whether it is still going on
• dated photographs, taken from your own property or from public land
• for a change of use, the pattern: times, days, how many vehicles, how often
• what actual harm it causes, in planning terms, such as loss of light, overlooking, noise from a commercial use, or traffic

The last one carries more weight than people realise, because whether to act turns on harm. “It is not fair that they did not apply” is not harm. “It blocks the light to my kitchen window all afternoon” is.

Leave out anything about the person rather than the land. Planning is about the use of land, not about who is using it, and a report that reads as a personal grievance is easy to deprioritise.

 

Will they know it was me?

 

This is the question people most want answered, and it is the one most often answered badly elsewhere. The honest position is that nothing in planning law gives you a right to anonymity. National planning guidance does not deal with complainants at all: it has nothing to say about who reports a breach, whether they can be named, or what they are entitled to. Everything below is council policy, which means it varies and you should read your own council’s enforcement policy.

That said, the pattern across published council policies is fairly consistent:

• councils treat your name and address as confidential and will not pass them to the person you have reported
• most councils will not investigate a completely anonymous report at all, partly to avoid wasting time on hoaxes, and partly because if it ever reaches court they need to be able to say a resident raised it
• confidentiality is not absolute: if the case reaches a prosecution or an appeal, you may be asked to give a witness statement, which is voluntary
• the council still holds your details, and information it holds can be subject to access to information law

There is also a practical point no policy can fix. The council will have to put the substance of the complaint to the owner, and the substance often gives you away. If yours is the only window overlooking the extension, your neighbour will draw their own conclusion whatever the council does or does not say.

If you want a step of distance, many councils suggest asking your ward councillor or your parish council to raise the matter on your behalf. That is a normal route and it is not a trick.

 

The council decides whether to act, and you do not

 

Even where the council agrees there has been a breach, it does not have to do anything about it. The law says it may act only where doing so is expedient. It is a power, not a duty, and it is the single biggest reason a report you thought was watertight ends in nothing.

What the council weighs up, 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. Read your own council’s plan if it has one, because it tells you where a case like yours sits in the queue.

So the likeliest outcome of a successful report is not demolition. It is that the council invites an application after the event, considers it in the normal way, and quite possibly grants it. That is a proper outcome, not a failure. Councils also have to weigh the effect of enforcing on the people who would be affected, including their home and family life.

 

What you will and will not be told

 

You have no right to be kept informed, and practice varies a great deal. Some councils give you a case reference and an officer and will update you. Others treat the enforcement file as confidential and will tell you very little, on the basis that the person being investigated has rights too.

What you can rely on is narrower, but it is real:

• if the council serves a notice, it goes on the public enforcement register, so you can check for yourself
• if an application for retrospective planning permission is made, it is publicised in the ordinary way and you can comment on it
• if an enforcement notice is appealed, the council may come back and ask whether you will support its case

 

How long it takes

 

Longer than you expect. Most councils triage a new report within a few weeks and then work to their own priority list, so anything they class as low harm can sit for a long time. Months is normal. Complicated cases run into years, particularly if a notice is served and appealed.

What happens in that time is an investigation, and it is more constrained than most people assume. Our guide to how a planning enforcement investigation works explains what an officer may actually do, and why none of it stops the clock.

One thing does argue for reporting sooner rather than later. There are time limits after which a breach becomes immune and nothing can be done about it, generally ten years in England, with a four year limit still applying in some older cases. Our page on enforcement time limits explains which applies. Sitting on something for years can quietly hand the other side a complete answer.

 

If the council decides to do nothing

 

There is no appeal. A person served with an enforcement notice can appeal it, and our guide to planning appeals covers how that works, but there is no equivalent for somebody who reported a breach and is unhappy that nothing came of it. Nobody will review the decision on its merits.

What you can do, in order:

• use the council’s own complaints procedure first, which you normally have to exhaust
• then complain to the Local Government and Social Care Ombudsman, in writing, normally within 12 months of when you first knew about the matter

Our page on the planning ombudsman works through all of this properly: when the twelve months actually starts running, what counts as the council going about things badly, what happens if it is found at fault, and what the Ombudsman can do if the council then ignores the finding.

Be clear about what the Ombudsman is for. It looks at whether the council went about things badly: losing your report, never investigating, ignoring its own enforcement policy, failing to answer for months. It cannot overturn a decision that was properly made, because the law says it may not question the merits of a decision taken without maladministration where the council was using its own discretion. In plain terms, it is there for how the council handled it, not for the fact you dislike the answer.

The only route that attacks the decision itself is judicial review in the High Court, which is expensive, has a very short deadline, and is rarely proportionate for a neighbour dispute.

 

Is there a cost?

 

Reporting is free. Searching the planning register is free. There is no fee for a council to investigate, and no fee to complain to the Ombudsman.

Costs only arise if you choose to take them on: professional advice if the matter is substantial, or legal costs if you were ever to go to the High Court. If your report leads to an application being made after the event, the fee for that is paid by the applicant, not by you, and is charged at the ordinary rate set out in our guide to planning application fees.

 

Before you report a breach of planning control

 

• check the planning register for a permission, and read its conditions
• check whether the work was permitted development and never needed permission
• check the enforcement register in case the council has already acted
• consider talking to your neighbour first, because a genuine mistake is often fixed faster that way than through a council file
• write down what you can see, when it started, and what harm it causes you
• take dated photographs from your own property or from public land
• give the council your name, since most will not act on an anonymous report
• read your own council’s enforcement policy so you know its priorities before you start
• expect months, and expect that the answer may be an application rather than a demolition
