In Scotland, who is responsible for a blocked drain comes down to where the blockage sits. A blockage in the private drain within your property boundary is the owner’s to sort. Once the pipe passes the boundary and joins the public network, it becomes Scottish Water’s.
In a tenement, a drain shared by the flats is a common repair split between the owners, usually set out in the title deeds. In a rented home it is normally the landlord’s, and a blocked gully in the road belongs to the council. The rest of this guide explains how to tell which one you are dealing with, who pays, and what to do when it is not clear, with a Glasgow tenement in mind throughout.
Who is responsible for a blocked drain in Scotland?
The quick answer is that responsibility follows the pipe. Trace where the blockage sits and you can usually work out whose job it is to clear it.
- Inside your home, and your own drain up to the property boundary: the owner.
- The public sewer beyond the boundary that serves more than one property: Scottish Water.
- A drain shared between flats in a tenement: the owners jointly, as a common repair.
- A blocked drain in a rented home: usually the landlord.
- A gully or drain in the public road: the council.
Each of those has its wrinkles, especially in a tenement where one drain can serve the whole close, so the sections below take them one at a time.
Private drain or public sewer: where does your responsibility end?
As a general rule in Scotland, everything from inside your home to the property boundary is your private drain and your responsibility. Beyond the boundary, once the pipe joins the shared public network, it is Scottish Water’s. The exact point of the split depends on how the pipes are laid, so where it matters, a survey can confirm it.
Scotland handles this differently from England. South of the border, water companies took over the drains beyond the boundary back in 2011, so people often read online that the water company owns that stretch. That transfer never happened in Scotland, where the older Sewerage (Scotland) Act 1968 still frames the split. Scottish Water’s own guidance puts it plainly: any pipework from inside your property to the boundary is usually your responsibility.
What counts as your private drain?
Your private drain is the pipework that serves only your property, from the fittings inside the house to the point where it meets the public sewer at or near the boundary. That covers both the foul water from your toilets and sinks and the surface water off your roof and paving, whether they run in separate pipes or one combined drain.
In a house it usually means the runs and inspection chambers under your garden or path. In a tenement it includes the branch from your own flat, though much of the underground drain is shared, which the next section covers.
What does Scottish Water look after?
Scottish Water looks after the public sewer network beyond your boundary, the shared pipes that carry waste away from more than one property. If a blockage is in that public sewer, they investigate and clear it at no cost to you. They do not attend blockages in your private or shared drains, and for those they point you to a licensed drainage professional.
Who is responsible for a shared drain in a Glasgow tenement?
In a tenement, a drain or soil stack that serves the whole building is a common repair shared between all the owners. A run that serves only some flats is a mutual repair for those owners, and a branch serving a single flat is that owner’s individual responsibility. Your title deeds come first, and where they are silent, the Tenement Management Scheme under the Tenements (Scotland) Act 2004 sets the default rules.
What do the title deeds say?
The title deeds are the first place to look, and in the Victorian tenements of the West End, Southside and Partick they often make the shared drains and the back-court gullies a common repair throughout the building. They may instead set out a particular split, and if the deeds are clear you have to follow them. Persistent blockages that one owner causes, by putting the wrong things down the drain, can be treated as damage that owner is responsible for.
How are the costs split between owners?
Where the deeds say nothing, are unclear or contradict each other, the Tenement Management Scheme applies. Its default is that all owners pay an equal share, with two exceptions. If the work only involves a part that some flats use, only those owners pay. If the largest flat is more than one and a half times the floor area of the smallest, the split shifts so the larger flat pays more. Decisions are made by vote, one per flat.
What does a factor do?
A property factor can organise a common repair, arrange the drainage work and bill each owner their share. Owners who prefer can self-factor and sort it between themselves instead. Either way, a shared drain is rarely one flat’s problem to fix alone, so it is worth knowing who factors your building before a blockage forces the question.
Landlord or tenant: who deals with a blocked drain in a rented home?
In a rented home in Scotland, the landlord is normally responsible for keeping the drains in working order, even when it is the tenant who reports the blockage. The one common exception is a blockage the tenant caused through misuse, which the tenant can be asked to put right.
The landlord’s duty comes from the Repairing Standard under the Housing (Scotland) Act 2006, section 13, which requires the drains, gutters and external pipes to be kept in a reasonable state of repair and proper working order, and the house wind and watertight. In a block of flats the landlord shares responsibility for the parts the tenant is entitled to use.
A private tenant whose landlord will not act can apply to the First-tier Tribunal for Scotland, through its Housing and Property Chamber. Council and social tenants have a separate Right to Repair scheme that covers certain urgent repairs, including a blocked foul drain where there is no other toilet in the house.
When is a blocked drain Scottish Water’s responsibility?
A blocked drain is Scottish Water’s responsibility when the blockage is in the public sewer, the shared network beyond your boundary that serves more than one property. They will investigate a reported blockage and clear it at no cost if it turns out to be theirs.
If several homes on the street are affected at once, the public sewer is the likely cause, and you can report it to Scottish Water, who investigate and clear a public-sewer blockage at no cost. What they will not do is attend a blockage inside your own boundary or a shared tenement drain, because those are private. For anything on your side of the boundary, a drainage engineer is the right call.
What about a blocked road gully or street drain?
A blocked gully or drain in the public road is the council’s responsibility, not Scottish Water’s and not the homeowner’s. In this area that means Glasgow City Council or North Lanarkshire Council, depending on where you are.
Report a flooded road gully or water pooling across the carriageway to the council’s roads department. Motorways and major trunk roads are handled separately by Transport Scotland. If the water is on the road rather than your property, it is almost never a job for a private drainage firm.
What to do when nobody’s sure whose drain it is
When it is not clear whose drain is blocked, work through it in order: check the title deeds, rule out the public sewer and the road, then treat what is left as a private or shared drain. That sequence usually settles it without a dispute.
Start with the title deeds if you own the flat, since they define what is shared and what is yours. If you suspect the public sewer, report it to Scottish Water, who will clear it free if it is theirs. If it is a road gully, report it to the council.
If it is your own or a shared tenement drain, a drainage engineer can trace and camera the line to pin down exactly where the blockage sits and whose section it is in, then clear a blocked drain properly once it is found. That takes the guesswork, and the neighbour stand-off, out of it.
Heavy rain can muddy the picture too, since a combined sewer can surcharge and back a shared drain up, which our guide to blocked drains after heavy rain in Glasgow explains.

Frequently asked questions
Who is responsible for a blocked drain in Scotland, me or Scottish Water?
It depends where the blockage is. Within your property boundary the drain is yours to clear. Beyond the boundary, in the public sewer that serves more than one property, it is Scottish Water’s, and they clear that at no cost. As a general rule, one property affected points to your drain, a whole street to the public sewer.
Who pays to fix a shared drain in a Glasgow tenement?
The owners share the cost. A drain serving the whole building is a common repair, split between all the flats, usually equally unless the title deeds say otherwise or the Tenement Management Scheme adjusts it. Check your title deeds first, as they take priority over the default rules.
Does the factor deal with a blocked drain in a block of flats?
A property factor can organise a common drainage repair and bill each owner their share, but the responsibility and cost still sit with the owners, not the factor. If your building self-factors, the owners arrange it between themselves. Either way a shared drain is a joint job, not one flat’s alone.
My landlord will not fix a blocked drain. What are my rights as a tenant in Scotland?
Your landlord is normally responsible for keeping drains in working order under the Repairing Standard. If they will not act, a private tenant can apply to the First-tier Tribunal for Scotland, and council or social tenants may use the Right to Repair scheme. A blockage you caused through misuse can be your responsibility, though.
Will Scottish Water clear a blocked drain for free?
Scottish Water clears blockages in the public sewer at no cost, and you can report one to them directly. They do not attend private drains within your boundary or shared tenement drains, so if the blockage is on your side, it is a job for a private drainage engineer rather than the water company.
Who do I call for a blocked drain in the road or a blocked street gully in Glasgow?
The council. Road gullies and drainage on public roads are maintained by Glasgow City Council or North Lanarkshire Council, not Scottish Water or a homeowner. Report a flooded road gully to the council’s roads department. Trunk roads and motorways are Transport Scotland’s.
How do I find out whether a blocked drain is mine, my neighbours’ or the public sewer?
Start with your title deeds, which set out what is shared in a tenement. Rule out the public sewer, by whether several homes are affected, and the road gully. If it is a private or shared drain, a drainage engineer can trace and camera the line to show exactly where the blockage is and whose section it sits in.
