Landlord plumbing responsibilities
Legally, a landlord must provide tenants with running water and sanitation fittings, including pipes and drains. A tenanted property must have:
A working toilet
A shower or a bathroom
At least one sink for washing up
The Landlord and Tenant Act 1985 requires property owners to keep the installations in the dwelling in repair and proper working order. That covers the supply of water, gas, and electricity, plus sanitation fittings like basins, sinks, baths, and toilets. It doesn't cover other fixtures, fittings, and appliances for making use of that supply.
Landlord responsibility for sinks, baths, and toilets
It's a landlord's responsibility to maintain the drainage, pipes, and other plumbing in a tenanted property, including repairs to sinks, baths, and toilets.
However, a tenant is liable for repair costs if a drain becomes blocked due to tenant misuse, and the same applies to the sanitary ware itself: damage caused by tenant misuse is the tenant's responsibility, while wear and tear or faulty installation is the landlord's. A tenant is responsible for plugs and chains for sinks, baths, and basins.
This split of responsibilities extends to heating too. Our guide on landlord heating obligations covers the boiler and hot water side in more detail.
Landlord responsibility for pipes and drains
Internal pipes
A leaking pipe within the property, whether from a tiny fracture or a loose connection, is the landlord's responsibility to repair. It'll usually show as a puddle under the pipework, or damp patches on walls or ceilings if the pipes are concealed.
Pipes can also burst if water inside them freezes and expands in cold weather. This is again the landlord's responsibility to fix.
To prevent flooding and minimise water damage, make sure both landlord and tenant know how to shut off the water supply to the property.
On Checkatrade, you'll only find trades who meet our high standards and pass up to 12 checks.
External pipes
The mains pipe bringing water to the property is either the landlord's or the water board's responsibility. If a mains pipe is leaking, contact the local water board to confirm which applies before arranging a repair.
Drains
At the tenanted property, the landlord is responsible for clearing blocked sewers, drains, and external waste pipes. A landlord is not responsible for road gullies, or for waste pipes blocked specifically by tenant misuse.
Landlord responsibility for the boiler and radiators
Boiler
A landlord is legally required to make sure the boiler is serviced and safe for continued use, instructing a Gas Safe registered engineer to inspect the gas supply and appliances at least every 12 months. See our guide on landlord responsibilities for the boiler and gas safety for more detail.
Radiators
A landlord is also responsible for radiators, pipework, fittings, and valves. A tenant must never attempt repairs themselves unless the tenancy agreement explicitly states otherwise, and shouldn't feel obligated to undertake repairs that are the landlord's responsibility.
That said, if a tenant's actions cause damage, for example, leaving a tap running and causing a bath to overflow, damaging the flat below, the tenant is responsible for the cost of repair to both properties.
Property maintenance cost - preventing expensive repairs
According to the Daily Mail, homeowners should spend 1% of the value of their home on improvements every year – just to maintain its worth in the marketplace! So, what kind of things should we maintain regularly? And how much exactly will it cost?
A major legal change worth knowing about
Since 1 May 2026, the Renters' Rights Act 2025 has abolished Section 21 "no-fault" evictions in England, with all tenancies converting to periodic contracts and possession only available through Section 8 grounds. This doesn't change your plumbing repair obligations directly, but it raises the stakes of getting repairs right and on time, since unresolved issues carry more weight in the current legal framework than under the old system. See our guide on property maintenance costs for landlords for the fuller picture.
How much do common plumbing repairs cost?
Costs vary by job, location, and plumber, so check our plumber cost guide and property maintenance cost guide for current pricing rather than a fixed figure.

It depends on the cause: tenant misuse means the tenant pays, but a problem with the pipes or drains is likely the landlord's responsibility.
Normally the landlord's, since it's typically caused by wear, a fault, or cold weather rather than tenant misuse.
Either the landlord or the water board, depending on the specific pipe. Contact your local water board to confirm which applies.
