Landlord Responsibilities for Plumbing in London Rental Properties

1 January 2025·8 min read

Section 11 Landlord and Tenant Act 1985

The primary legislation governing landlord repair obligations in England is Section 11 of the Landlord and Tenant Act 1985. This implies a covenant into all short tenancies (under 7 years) requiring the landlord to keep in repair and proper working order:

  • The structure and exterior of the dwelling
  • Installations for the supply of water, gas, electricity and sanitation
  • Installations for space heating and heating water

What This Means for Plumbing

Under Section 11, landlords are responsible for:

  • The boiler and central heating system — repair and maintenance
  • Hot water supply — the immersion heater, unvented cylinder or combi boiler providing hot water
  • Cold water supply — pipework from the boundary to the property
  • Drainage — blockages caused by condition (not tenant misuse), drain collapses, root ingress
  • Toilet, bath, basin and shower installations — where faults arise from condition not misuse

When Tenants Are Responsible

Tenants are generally responsible for blockages caused by misuse (flushing wet wipes, pouring fat down drains), accidental damage they caused, and minor maintenance like bleeding radiators or changing batteries in thermostats.

Frequently asked questions

How quickly must a landlord fix a broken boiler in London?

There is no specific statutory timescale, but case law and best practice suggests urgent repairs (heating, hot water, water supply) should be completed within 24 hours. For vulnerable tenants — elderly, disabled, families with young children — the urgency is greater. Failure to repair within a reasonable time exposes landlords to rent repayment orders.

Who is responsible for a water leak in a London rental flat?

If the leak is from the property's pipework or a failed fitting (not caused by tenant misuse), the landlord is responsible. If a tenant's negligence caused the leak (e.g., left a tap running, overfilled a bath), the tenant bears responsibility — though the landlord must still arrange the repair and then recover costs.

Does the landlord need to provide central heating in London?

Yes — under Section 11, landlords must maintain heating installations. A property without working central heating in winter is in breach. The Fitness for Human Habitation Act 2018 also requires that a property is fit to live in, which includes adequate heating. Properties that cannot maintain 18°C in living rooms fail the fitness standard.
