Who is responsible for blocked drains depends on which section is affected and how the local drainage network is arranged. We investigate the drainage problem and explain what can be established from the accessible pipework. A drain inside a garden is not automatically privately maintained.

Network responsibility
A property boundary does not by itself determine who maintains a shared or lateral drain.
Rented property
Tenancy repair responsibility is separate from ownership of the wider sewer network.
Private drains, lateral drains and shared sewers
In England and Wales, many lateral drains and shared sewers are maintained by sewerage companies, although exceptions apply. Scotland and Northern Ireland have different arrangements. The actual network needs checking rather than relying on the property boundary alone.

Rented property and drainage responsibility
Responsibility under a tenancy is a separate issue from ownership of the wider sewer network. A landlord or managing agent should normally be told promptly about a drainage problem, especially where sewage backflow or essential facilities are affected.
What the drainage findings can show
The blockage position, connected pipes and any visible damage can help identify which part of the system is involved. Those findings should not be used to assign blame to an occupier where the drainage layout or cause remains uncertain.
Who Is Responsible for Blocked Drains?: common questions
Is a drain in my garden always my responsibility?
No. Public or shared infrastructure can cross private land.
Does a shared drain always belong to the sewerage company?
No. Many shared sewers are maintained by sewerage companies, but the actual arrangement and national rules need checking.
Who should a tenant contact first?
Normally the landlord or managing agent, with the sewerage company involved where its network may be affected.
Is the first property to overflow necessarily responsible?
No. The visible symptom can be upstream of a shared restriction.
Do drainage responsibility rules differ across the UK?
Yes. England and Wales, Scotland and Northern Ireland have different network arrangements.
