Drainage Issues Housing Disrepair Claims

Persistent drainage problems in a rented home — blocked drains, slow-draining sinks, or sewage backing up — are your landlord's responsibility to fix. Poor drainage causes flooding, foul smells, hygiene risks, and damage to floors and fixtures. If your landlord has been notified and failed to act, you have the right to claim compensation.

What the Law Says

Section 11 of the Landlord and Tenant Act 1985 requires landlords to maintain installations for drainage in proper working order. The Homes (Fitness for Human Habitation) Act 2018 requires proper sanitation as part of fitness for occupation. Sewage backing up into a property is a Category 1 hazard under the HHSRS requiring immediate action.

Common Causes

Blocked drains or soil stacks — Accumulated debris, grease, or roots can cause water to back up and overflow inside or outside the property.

Collapsed or damaged drain pipes — Older clay or concrete drainage pipes can crack or collapse, causing persistent blockages.

Sewage backing up — Blockages in shared or main drains can cause sewage to back up into sinks, baths, or toilets — an urgent health hazard.

Blocked or overflowing gutters — External gutters that overflow discharge water against the building and overload drainage.

Poorly graded drainage — Drainage systems installed incorrectly may never drain efficiently and require structural remediation.

Warning Signs to Watch For

Water pooling around drains outside or on hard surfaces near the property
Gurgling sounds from sinks, toilets, or baths when other fixtures are used
Foul or sewage smell inside or outside the property
Slow-draining sinks, baths, or showers despite not being blocked by visible debris
Water or sewage overflowing from external drainage inspection chambers
Damp patches on ground floor walls or floors near drainage runs

Landlord Response Timeframes
