Drain clearance in London: Homeowners vs renters

For homeowners:

• You’re usually responsible for any drain problems within the boundaries of your property.
• This includes indoor pipes and outdoor drains up to the edge of your land.
• If you suspect the issue is further along (in a lateral drain or public sewer), it’s worth checking with your local water company.

For renters:

• Minor blockages (like a sink clog) might be down to you.
• Structural issues or anything outside the property boundary is your landlord’s responsibility.
• Always check your tenancy agreement, and report serious problems to your landlord or letting agent straight away.
