Neighbour Drainage and Guttering Issues

Drains vs Sewers: The Legal Difference

A drain is a pipe that only takes water from buildings within a single property boundary. It might carry foul water (toilet waste) or surface water (rainwater from the roof). If it's on your property, you are responsible for unblocking and repairing it until it reaches someone else's property.

A pipe becomes a sewer at the point where it takes drainage from multiple properties. Your local water company is responsible for clearing blockages and maintaining public sewers.

If you're struggling to work out whether it's your responsibility or your neighbour's, you can use our free Drainage Responsibility Checker.

Who is Responsible? The 2011 Law Change

Before 2011, some properties shared "private sewers" and owners were jointly responsible for maintenance. Since the law changed, you are only responsible for drains within your own property boundary. Your water company now handles everything beyond that point.

Detached homes: Before 2011, you maintained drains up to the main sewer, possibly under the pavement or road. Now, your responsibility ends at your property boundary.
Semi-detached homes: You are responsible only for the section up to your boundary with the adjoining house. If a shared drain crosses your property from your neighbour's, the water company is responsible for that section: not you.
Terraced houses: You are responsible only for the part of your drain before it connects to the shared drain serving the row. The water company maintains the shared drain itself.

Properties with a cesspit, septic tank or treatment plant (common in rural areas) were not affected by these changes and remain privately maintained. Private pumping stations have also transferred to water company responsibility.

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

What to Do About a Blockage

If you suspect a blocked sewer, contact your local water company. If they find the blockage is within your drain (the part you're responsible for), you will need to clear it yourself or hire a drainage company.

Most drain unblocking companies invoice the person who called them, regardless of who is legally responsible. If you live in a terrace or semi-detached home and the blockage originates from a neighbour's drain, you will need to approach them for payment. Your local council has powers under various Public Health acts to serve legal notices on anyone who fails to clear a blockage.

Shared Guttering and Uncooperative Neighbours

If guttering or drainage is shared between properties, there is normally joint responsibility for maintenance and repair. Check your deeds to confirm whether this applies to you.

Talk to your neighbour before arranging any work. Most will be reasonable, especially when you have the deeds to support your position. If they refuse to contribute, get the work done and request reimbursement of their share in writing. If they still won't pay, you can take the matter to the county court.

Ask Problem Neighbours a Question

@Ron D This sounds like a nuisance claim, and possibly trespass by water, which your neighbour is legally liable for. Start by sending a formal letter (keep a copy) stating the damage, dates, and that you hold him responsible for repair costs and any damp remediation. If he ignores it, contact your local council's environmental health team, as persistent water ingress from a neighbouring property can be actionable. Citizens Advice offer free guidance, and your home insurer may cover legal expenses to pursue him without upfront cost to you.

Ron D 26/07/2026 at 7:57 pm

What should we do, when our semi-detached neighbour refuses to do anything over our complaint that his extension roof and part of his main roof is overflowing into our separate guttering causing a damp wall. This occurs in any heavy downpour. The problem has effectively existed since 2008 with only ineffective DIY attempts to resolve it, in spite of numerous direct complaints. We are unable to afford any significant costs as we are both in our Eighties. Thank you in anticipation of any any helpful advice you can provide.

Neighbour has raised his garden height and started to build something. Now he’s laying water pipes underground to his property.
We share a sewage drain with him.
Will this interfere with our drainage system.
I have notice our tap water not working very well. Could this be the reason.
Thanks for your help.

ProblemNeighbours Editor 19/06/2026 at 8:01 am

@Question That sounds like a genuine public health issue, so report it to your local council's Environmental Health team. Foul water escaping onto a public pavement is a statutory nuisance under the Environmental Protection Act 1990, and they have powers to serve an abatement notice on the property owner. It's also worth flagging it to the water company (Thames Water, Severn Trent or whoever covers your area), as the leak may be coming from a drain they're responsible for. Photos and dates will help your case.

Question 19/06/2026 at 7:53 am

There is a house which has foul water leaking out from somewhere within the boundary near the end of the driveway over the pavement and into the road. It’s not my neighbour, but the water drains near a bus stop and the buses splash the dirty smelly water up into the pavement, and the people waiting at the bus stop have to stand with the horrible smell. It’s been like it for many months. Is there anything that can be done?

Skip 04/06/2024 at 10:25 am

We are a detached property and the manhole cover we have within our boundary has a connection to our neighbours sewerage it then goes from this manhole under our lawn to the road.
Who is responsible for the drain from the manhole to the road? it is taking two properties sewage? My thoughts were the council as its a shared sewer/drain.

Thanks

We live in a detached property and the neighbour behind us wall was falling down. They had the wall re built with the same brick and it has been so badly finished. We however heard him talking to the builders about standing rain water but didn’t think anything of it. We have however noticed they have run which looks like a pipe in the wall that wasn’t there before to drain said standing rainwater.

Is this allowed? I think not as it’s not natural drainage. We have tried to approach them about this but they are now ignoring us and pretending they knew nothing about it. Are we in our rights to block this up as I don’t think it should be there to begin with as was never there before and I have photos to show that too.

ProblemNeighbours Editor 17/05/2026 at 10:21 am

@None That sounds like a drainage covenant issue, and it's worth checking your deeds because in many terraces the rainwater layout is shared by historic design, not choice. If your downpipes can't cope in heavy rain, the overflow could be classed as a nuisance, so the other owners may be liable to contribute to upgrades or maintenance. I'd get a drainage survey done and write to the neighbours jointly. Citizens Advice or a party wall surveyor can point you the right way.

I live in a terraced hous a have three down pipes because I take the roof load off 5 houses and get a overflow in bad rain should each property have to see to there own watershed

My Neighbour has the only stack pipe for the gutter water and it is in the middle of 3 properties, his gutter is blocked, so our gutters are over flowing causing damage to our property because the water has nowhere to go, he will not clean his gutter, what can I do make him clear.

CB 04/11/2023 at 7:30 am

We live in a semi detached house. Our neighbour (who isn’t attached to us) only has one downpipe to take all the rainwater from the guttering around their property.

That downpipe is on the side of the property and does not drain into a soakaway.

The result of this is all of the rain water from their roof drains over our driveway and onto the pavement and road. It’s an adopted road.

I don’t think this should happen but I’m not sure who to address it with. We’ve already spoke to the neighbour and they have no intention of doing anything about it.

Any advice would be gratefully received.

Moose 01/11/2023 at 10:44 am

My neighbour before him has blocked all his rain water drains so all the water is flowing to my house and overflowing over the troughing this is making my walls mouldy. I have had people out to fix it but just ends up overflowing again.

Syl 17/10/2023 at 12:39 pm

I share a cess pit with my neighbour. He wants a new drain cover as the cess pit is in garden who is responsible for buying this cover?

Markar 07/08/2023 at 8:18 pm

I hope somebody can give me some help. I live in a semi detached house and the neighbour that isn't attached had a flat roof towards my property but has now put a sloped roof on it towards my property. How do I go regarding guttering and down pipes, should he put these on as the eaves and roof edge is basically on my property (air space). Please help.

My neighbours have had repair work done to the sewer pipes (we live in a terrace). We were not aware of any issues with the drainage but they recently had an extension to their house with lots of heavy machinery on the ground. They apparently unblocked our sewer pipe during the work and have sent us a bill for the costs. The work was done by a family members business, no communication or consent was given at all about the work. The first we knew was a bill that came through our door.They have now sent us a letter threatening court action unless we pay. What are our rights?

Den 25/07/2023 at 9:31 pm

My neighbours have put up a conservatory, but have not put guttering up on my side. So every time it rain it floods my side , is there a legal requirement to gutter my side , answers please ??, …

Grass 08/07/2023 at 2:07 pm

I live in a flat, 4 in a block, the house above me is rented out, usually to short term working guys, their garden is a mess over grown grass and weeds, I enter my garden via there's, bit it's getting dangerous with the pathway getting overgrown, I struggle in and out the property with my baby in a buggy, who can I complain to get the garden sorted, or at least the pathway cleared. I dont know who the landlord is, and the guys living there are not interested, or pretend they dont understand as they are foreign workers and only stay for a few months until another crowd of men come. Looking for advice.
