Neighbour Contravening Planning Regulations: What to Do

Originally written by Jeff Durham, updated by the editorial team on 18th May 2026

Understanding planning regulations

Planning regulations balance your neighbour's right to improve their property against the interests of those living nearby. They cover the size and position of extensions, changes to a building's appearance, and alterations to how a property is used.

When these rules are ignored, the effects can be real: loss of natural light, reduced privacy, increased noise, or parking problems. If you suspect work is being done without proper permission, or has strayed from what was approved, there are steps you can take.

When does a neighbour need planning permission?

Not all building work requires planning permission. Many smaller projects fall under permitted development rights, which allow certain changes without an application, provided they stay within set limits on size, height, and position.

Permitted development typically covers:

Small single-storey rear extensions
Loft conversions within certain dimensions
Garden sheds, greenhouses, and outbuildings below a certain size
Some fencing, walls, and gates
Solar panels on roofs, subject to conditions

These rights can be removed in conservation areas, on listed buildings, or where an Article 4 direction applies. Flats and maisonettes generally do not benefit from the same allowances as houses.

Planning permission is usually needed for:

Large extensions or those at the front of a property
New buildings exceeding permitted development limits
Changes of use, such as converting a house into flats or running a business that changes the building's character
Work affecting listed buildings or in conservation areas

Permitted development rules vary between England, Scotland, Wales, and Northern Ireland. The Planning Portal provides guidance for England and Wales. For Scotland, use ePlanning Scotland. For Northern Ireland, use Planning Portal NI.

How to check if permission was granted

Before raising concerns, check whether your neighbour needed permission and whether they obtained it. Every local planning authority maintains a public register of applications, searchable online through your council's website.

Enter the property address to see any applications, decisions, and conditions attached. Planning applications include drawings and descriptions, so you can compare what was approved against what is being built. If the work differs significantly from approved plans, this may indicate a breach of conditions.

If you find no record of an application, the work may fall under permitted development, or your neighbour may have failed to apply when required.

Your situation may be slightly different. ask a question below ↓ and our editorial team will reply with our advice.

What counts as a planning breach

A planning breach occurs when development is carried out without permission, or when work does not comply with approval conditions. Common examples include:

Building an extension larger than approved
Using a property for a purpose requiring permission, such as running a commercial operation from a home
Ignoring conditions about materials, working hours, or landscaping
Erecting structures exceeding permitted development limits
Removing trees protected by a Tree Preservation Order

Enforcement action is discretionary. Councils consider whether the breach causes genuine harm before deciding to act, and limited resources mean they prioritise based on severity.

Time limits apply. For most breaches, the local authority has four years to act. For changes of use and breaches of conditions, the period is ten years. After these periods, development may become lawful. Where a breach has been deliberately concealed, time limits can be extended.

Reporting a suspected breach

Report concerns to your local planning authority. Most councils have an online form, or you can write or telephone the planning enforcement team.

Include:

The property address
A description of the work or activity you believe breaches regulations
When the work started or when you first noticed it
Photographs showing what has been done
Your contact details (some councils accept anonymous reports)

The council will usually acknowledge your report and may investigate through site visits, planning record reviews, and correspondence with the owner. This can take time, particularly with high caseloads or complex breaches.

If a harmful breach is confirmed, the council may negotiate a remedy, invite a retrospective application, or take formal enforcement action. An enforcement notice requires the owner to correct the breach within a set period. Owners can appeal, which delays proceedings. Failure to comply with an unappealed notice can result in prosecution.

You can ask the council for updates. If unhappy with how your complaint is handled, use the council's complaints procedure or contact the Local Government and Social Care Ombudsman.

Consider speaking to your neighbour directly. They may not realise they have done anything wrong. A calm conversation can sometimes resolve matters faster than official channels. If the relationship is already difficult, reporting to the council without direct contact is reasonable.

For complex or contentious disputes, seek legal advice from a solicitor experienced in planning matters. For further guidance, visit GOV.UK or contact your local council's planning department.

@Sunbeam It's possible, unfortunately. If the terrace previously had lawful use as a roof terrace over 20 years ago, the neighbours may argue it's a reinstatement rather than a new development, though the new railings and decking would normally still need planning permission given the overlooking. Chase Warwick DC in writing for a formal decision from the enforcement officer, and ask specifically about the loss of privacy under the NPPF. If you're unhappy with their response, you can escalate via the council's complaints procedure or the Local Government Ombudsman.

Sunbeam 10/08/2026 at 7:04 pm

Our neighbour constructed a first floor walk out terrace on a first floor flat roof. The roof was a terrace over 20 years ago and the access doors and railings had been dismantled. They constructed it themselves using decking railings along the boundary, the terrace allows sight into our kitchen, lounge and over our outdoor patio dining area at a distance of less than 3m away and at a height of 2.4m. We reported our loss of privacy to the Warwick District Council over 3 months ago but they haven't done anything other than an enforcement officer visited a while ago. The neighbours are giving us the impression that they are going to be able to keep the terrace. Could that be right?

ProblemNeighbours Editor 17/05/2026 at 1:29 pm

@Veem That raised platform almost certainly needed planning permission, as outbuildings and decking over 300mm in height usually fall outside permitted development, and there are also overlooking and privacy issues to consider. Your first step is to report it to your local council's planning enforcement team, who can investigate and potentially require it to be removed or lowered. It's worth putting your concerns in writing and mentioning the loss of privacy specifically. Take some photos from your garden showing the overlooking too, as that helps their case.

Veem 14/05/2024 at 12:10 pm

My neighbour has built a seating platform above his summer house, we live in bungalows, so this is quite high, they had also tried to increase height of fence with cheap trellis and artificial grass, but they can still look into our properties from the platform, is there anything that we can do thank you

EB 16/02/2024 at 4:35 pm

a neighbour has put in planning for a shipping container to be stored at his house and also put in a large concrete base where he plans to store 15 vintage tractors. We are a semi detached house and this will be a complete eyesore from my windows and i am very concerned about the noise and fumes from the tractors. He said they are for a hobby not commercial. He does not empathise with the fact I have an autistic son in the house who is sensitive to noise and when I have asked him not to burn rubbish near the house, he ignores my requests. I have lived in the house 20 years and he is a new neighbour. I will be objecting to planning permission but would like to know if there are any technical grounds I could object on to make my case stronger? Thanks

Trouble 16/01/2024 at 1:14 pm

My neighbour has had a side extension to the boundary line, we did not object as in the plans the front of the extension was going to be a roller door, therefore they could still access the back of their property. However they have altered the extension and put a window in , there bins are now stored at the front of the house and they keep using our drive to access the back. The extension is not finished yet they are awaiting new windows!!! Is this allowed?

Livid 09/10/2023 at 1:23 pm

Our neighbour was given Planning Permission to build a 3 car garage and workshop on the condition the roof line was lowered to 4metres and there was to be no living accomodation above the garage.

3 weeks ago as the trusses were delivered and as they were swung into place I informed the Planning Department. The roof had not been lowered and the trusses would accommodate a flat.

The roof went on at an unbelievable pace and I sent picture of louvre windows in both sides of the roof.

Our road is being closed soon for 3 for days to install gas to the property.

The enforcement Officer informs me the Planning laws are laid down in such a way that until the flat is occupied she can do nothing.
What is the likelihood of the builder getting retrospective permission for the flat?
Is there any civil action I can take to stop gas and the electrics for a flat being installed?

AllyAllyO 29/08/2023 at 9:48 am

Our neighbours submitted plans for an extension which we didn’t object to. We are the mid terrace bungalow of 3. They are having a semi pitched & flat roof with a parapet coming from the base of the eaves (as we know you cannot have the eaves higher than the original property). We have a small garden 4.5m in depth and our neighbours garden wraps around ours. We are now faced with extra height to the party wall of 7500 without the addition of a coping stone. The eaves have been raised 400 and consequently so has the roof. The daylight assessment was done to the original plans, not to the actual build. Planning enforcement are dragging their heels, and we have had to commission a daylight surveyor as our light has been cut drastically. How can they get away with this?

Nettle 30/07/2023 at 4:08 pm

My neighbour has built a garden room at the end of his garden that is so close to the fence he had to stand in our garden to fit the gutter. It is also above the 8ft fence on its sides so the pitch of the roof is even higher. He’s now begun to construct something out to the front of it which brings it even closer to another part of our garden. I’m sure I read you can’t construct anything above 2.5 metres within 2 metres of a boundary. Can any one advise what can be done and where I can take this?

Dom 29/07/2023 at 7:39 am

My neighbour obtained planning permission to build a child nursery. The plans state 2.2m high. It is being built approximately 3m. Also, windows are being installed over looking my fence directly into my garden and rear of house. These were not on the drawings. What should I do?

Michelle 28/07/2023 at 7:45 pm

My neighbour has dug about 10 foot down on our boundary to level their land which they have walled. The wall on our side is around 6 bricks high and has left us with a massive drop, which is pretty dangerous. He said he would build a fence, but is ignoring my requests. What rights do I have?

Hi Laura (Crintie)
It sounds like planning permission and/or building regulations are not in place as you would have had a letter with their plans and the opportunity to agree or dispute the plans.
It might be time to contact your local Council and/or try to find out if you can get a building inspector to go and visit the property. They sound like rogue builders and cutting corners could be detrimental to nearby properties and land.
Good Luck Laura!

Crintie 26/07/2023 at 8:30 am

Builders are completely gutting a house a few doors down from me. It has been going on for months. The work times are completely random. I have not seen one lorry with a company name/logo.

I am concerned for the neighbours directly either side - that their houses do not collapse.
It appears to be a cowboy outfit doing the work.

Also the house is not in a safe location for large trucks and lorries to park. It is right on a mini roundabout. It blocks ambulances, buses and cars. There have been many near misses of very nasty accidents and potential punch ups between builders and terrified cyclists, motorbikes etc.

How do I find out if this is a legal price of work taking place?

Thank you for you time.

Kind regards,

Laura

House next door is on the market for sale problem is lean to / conservatory is built over the boundary onto our land Estate agent informed me that it would advertise property with a notice that it had to be taken down by purchasers but no mention of this in estate agent’s paperwork. HELP

Jenz 26/06/2023 at 10:42 am

My neighbour has built a loft conversion without planning permission with big double doors that look down through my roof lantern. He stands with the doors open and watches me whist I'm in my kitchen and now my privacy has gone inside and outside as he stands watching me and my children playing in the garden. We have lost all privacy.

Cape 22/06/2023 at 5:19 am

I am in the process of having my house rendered but as soon as they put the scaffolding up my awful neighbour got in touch with the council who sent an enforcement officer round to tell me I needed planning permission to render my detached house. I’ve never heard of this before what happens if I don’t put in for planning. The planning say it’s something they don’t normally bother about but as I was reported they have to take action

SERENDIPITY 15/05/2023 at 5:07 pm

Hi I bought house, new development in Sept 2022. Build has put fence short of my boundary line (boundary confirmed via map from Developer solicitor!). Neighbour to rear, not part of development has therefore gained and started planting trees etc. Neighbours have been in their property 20+ years but the part they are now using was full of trees etc and all cleared out as part of development. Where do I stand? Neighbours have been haven't sight of their boundary lines and mine but refusing to allow me to move fence. My solicitor getting nowhere with Developer solicitor yet. So I haven't got access to what was sold to me. How is that fair??

R786 02/05/2023 at 12:36 am

My Neighbour is planning to do double storey front and rear extension.

The architect he is using is a RIBA qualified chartered architect he knows his stuff.
The extension does not effect our sunlight neither the privacy also it is below the 50% of the land owned. However I don't want them to get their permission granted as I fear it will devalue my home. What can I do

Jaz 30/04/2023 at 7:00 pm

Our neighbours have placed what looks like a nuclear bunker behind their garage to use as an air bnb. However this has taken away some of our light from our kitchen and they have created a walkway for guests to use which means they will be accessing this new building right up against our hedge, being able to look over into our garden. I don’t think they’ve had planning for this. Not only is it hideous looking we will now have random holidaymakers lioojihg into our garden whereas said guests can’t see into the owners’ own garden because they have built a fenced off area high enough that guests won’t be able to. Feel like reporting them but don’t want to fall out with them either. Have thought about asking them to build a fence along the hedge but it still doesn’t cancel out the fact that we have lost light from our kitchen.

Fiona 20/03/2023 at 8:01 pm

Hello,
Similar to Gills comment from 17Mar I have sane issue of 3 windows set to overlook my living room after a self build next door has been granted planning permission. The original windows were much smaller on the plans provided to us so I didn’t initially have an issue. However, now that the skin of the building has gone up, the windows are around 2.5 times bigger and will directly over look our living room. Any ideas of rights here? Thank uou
