Landlord or Tenant: Who Pays for a Plumbing Repair?

Where the line between landlord and tenant actually sits

On a normal residential tenancy the landlord is responsible for the installations that supply water, heat water and carry waste away. That covers the pipework, the stopcock, the boiler, the cylinder, the taps and their cartridges, the cistern internals, the waste pipes and the drains. The tenant is responsible for damage they or their visitors caused, and for the small upkeep that comes with using the place carefully.

The landlord side comes from section 11 of the Landlord and Tenant Act 1985 and cannot be written out of a tenancy agreement. A clause making the tenant maintain the plumbing does not work on a short residential let, however willingly it was signed. The tenant side is older and softer: you behave in what the courts call a tenant like manner. Clearing hair out of a shower trap is tenant like. Replacing a shower pump is not.

So the grey area reduces to one question. Was this ordinary failure of an ageing installation, or was it caused by how the property was used? Corrosion, limescale, perished washers, a seized valve and a fatigued flexible tail are ordinary failure. A cracked basin, a snapped tap head, a washing machine hose pulled off at the back and a toilet blocked by something that should never have gone down it are not.

• Landlord: pipework, drains, stopcock, boiler, cylinder, taps, cistern internals, water heaters
• Landlord: anything that failed through age, corrosion, scale or wear
• Tenant: damage by the tenant, their household or their visitors
• Tenant: small upkeep such as clearing a shower trap or a sink strainer
• Tenant: appliances they own, and the hoses feeding them

What the landlord pays for

If the landlord installed it and it has failed on its own, the landlord pays, including the call-out and the labour. Age is not a defence. A thirty year old gate valve that will no longer close, a rotted soil branch, a failed thermostatic cartridge, a leaking cylinder and a boiler that no longer heats water are all landlord repairs, and all were predictable.

The full picture of what a landlord owes on the hot water side, and how quickly they owe it, sits under landlord hot water responsibilities, which takes the same duty from the appliance end rather than from the argument end.

A hot water cylinder leaking into the airing cupboard belongs firmly in that list, and it is one of the few faults on it that gets more expensive by the hour rather than by the week, because the floor underneath it and the ceiling underneath that are on the landlord's side of the line as well. Nobody saves money by treating it as a Monday morning problem on a Friday night.

London stock makes these bills bigger than they need to be. In Victorian and Edwardian conversions the pipework is buried in walls and under floors that were never meant to be lifted, so a small leak becomes a tracing job before it becomes a repair, and proper leak detection and repair is cheaper than opening four rooms on a guess. In purpose built blocks a thermal store such as a Pulsacoil sits in a cupboard and goes unserviced until it fails completely. In new build flats the heating pipework runs in liquid screed over the slab, so a tenant reporting a warm patch on the floor should be taken seriously the same day.

Hard water runs across most of the London supply area and quietly decides the repair bill. Scale coats immersion elements, ruins thermostatic shower cartridges and destroys the seats in tap valves. None of that is the tenant's doing. A landlord replacing the same shower cartridge every eighteen months is paying for water chemistry, not for tenant abuse.

A landlord cannot charge a tenant for a repair simply because the tenant happened to be using the fitting when it failed. Failure under normal use is fair wear and tear, and that is the landlord's cost.

What the tenant pays for

A tenant pays where their own behaviour, their own belongings or their own neglect caused the failure: physical damage, foreign objects in the drainage, and faults reported far too late. If a tenant let a slow leak under a sink run for four months rather than reporting it, the tap is still the landlord's repair but the ruined floor and cabinet are arguable.

Tenant owned appliances are the common surprise. A washing machine the tenant brought with them is theirs, and so is the flexible hose connecting it. When that hose splits behind the machine at three in the morning, the landlord owes the repair to his own pipework, but the machine and its hose are the tenant's. The same goes for a dishwasher, or a filter tap plumbed in by a friend.

Frozen pipes sit in an uncomfortable middle. A pipe left unlagged in a cold loft is a landlord failing. A pipe that froze because the tenant went away for three weeks in January with the heating switched off is usually treated as the tenant's doing.

• Blockages caused by wipes, sanitary items, cooking fat, food waste or hair
• Cracked basins, broken toilet seats, snapped tap heads and damaged shower screens
• Anything connected to an appliance the tenant owns
• Damage that grew because a known fault was never reported
• Frozen pipes caused by leaving the property unheated in winter

Who pays for a blocked toilet or a blocked sink?

It depends entirely on what comes out of the pipe, and the engineer will know within minutes. Wipes, cotton buds, sanitary products, a toy or a solid plug of cooking fat make it tenant caused, and the tenant pays. A collapsed pipe, a wrong fall, a branch furred with years of scale and fat, root ingress in a drain, or a blockage in a shared stack serving several flats make it the landlord's.

Wipes cause more tenancy arguments than anything else in a flat. Packaging that says flushable means only that the sheet will leave the pan. It does not break down like paper, it catches on anything rough in the branch, and it collects fat until the bore is gone. An engineer clearing a toilet in a converted terrace usually pulls out a rope of them, and a photograph of that ends the discussion.

Shared stacks flip the answer completely. In a converted house or a block, several flats discharge into one vertical stack, and when that blocks the water backs up into the lowest appliance in the building. The tenant who finds their ground floor bath filling with somebody else's waste has done nothing wrong, and nor has their landlord. That is a building issue for the freeholder, paid from the service charge.

If a toilet is overflowing or waste is backing up into a bath or shower, stop using every appliance in the property including the washing machine, and report it immediately. Running more water into a blocked stack turns a blockage into a flood.

What counts as an emergency, and who pays the out of hours call-out?

An emergency is anything unsafe or anything actively causing damage: water escaping and not stoppable at the stopcock, a burst pipe, a leak through a ceiling, waste backing up into a bath, a cylinder discharging hot water and steam, no water at all, or a total loss of heating and hot water in cold weather. A dripping tap, a running overflow and a slow drain are not, and a tenant calling an engineer out at midnight for one of those is on weak ground when they ask to be reimbursed.

Who pays follows responsibility, not the clock. If the failure is the landlord's, the landlord pays the call-out even when it lands on a Sunday, and an out of hours attendance costs more than a booked weekday one because of how the trade prices its own time. If the tenant caused it, the tenant pays, including whatever premium the hour carries.

The practical rule for a tenant is to stop the damage first and argue afterwards. Find the stopcock before you need it, usually under the kitchen sink or in a hall cupboard, and check it turns. Close it, switch off the electrics to anything the water has reached, photograph everything, then make the call. Nobody has ever lost a disrepair argument for turning the water off too quickly.

Responsibility and sequence are separate questions, and mixing them up is what turns a wet carpet into a wet flat. Water escaping in the house has an order to it that does not depend on whose bill it eventually is, and following that order protects the tenant whichever way the argument goes afterwards. A burst pipe repair on a copper run in a cold void is a straightforward job once the water is off and a serious one while it is still running, and the difference between those two visits is a few minutes at the stopcock rather than anything either party agreed in the tenancy.

• Emergency: escaping water, a burst pipe, a ceiling leak, waste backing up, a discharging cylinder
• Emergency: no water, or no heating and no hot water in cold weather
• Not an emergency: a dripping tap, a slow drain, a noisy pipe, a loose toilet seat

Can a tenant call a plumber and send the landlord the bill?

Sometimes, but not casually and not as a first move. There is a recognised route where a tenant arranges a repair the landlord has refused to do and recovers the cost from future rent, but it is narrow and procedural. It needs the fault reported in writing, a clear written warning that you will do the work yourself, a reasonable period to comply, more than one quotation, and a proper invoice. Skip a step and you are simply a tenant in arrears.

A genuine emergency is treated more sympathetically. If water is pouring through a light fitting at two in the morning and both the landlord and the agent are unreachable, a tenant who calls an emergency plumber to stop the escape has acted reasonably, and most landlords pay without argument because the alternative was a far larger bill. Keep every message you sent trying to reach them.

The leak came from the flat upstairs, so who pays?

In a block or a converted house, a leak from above is neither your landlord's repair nor yours. The owner of the flat where it started is responsible for their own pipework and for the damage it causes below, and in practice the claim runs through the buildings insurance the freeholder holds for the whole building. Your landlord's job is to chase it and put your flat right. Yours is to report it fast and document it.

It gets slow because three parties and an insurer each wait for the others. What shortens it is evidence gathered on the day: video of the water while it is running, the time it started, which rooms are affected, and what has been damaged. If the source is not obvious somebody has to trace it, and a flat owner refusing access is the usual reason a ceiling gets worse for a fortnight.

Do not let anyone cut a hole in a ceiling that is holding water until the supply above has been isolated. A bulging ceiling is a bath of water sitting on plasterboard, and it comes down all at once.

What a tenant is entitled to while the repair is outstanding

A tenant is entitled to the repair within a reasonable time of reporting it, to be told what is happening, to at least twenty four hours notice in writing before a non emergency visit, and to a home that stays fit to live in. There is no statutory stopwatch, so reasonable is judged against how serious the loss is and how cold it is outside.

The repairing duty does not start until the landlord knows, and that fact decides most disputes. Report in writing even when you have already phoned, and keep it on one email thread. Say what is not working, when it started, and whether anyone in the household is very young, elderly, disabled or unwell, because that changes the urgency. A photograph does more than a paragraph.

If nothing happens, the local council environmental health team is the most effective and most underused next step. They can inspect, assess the hazard and require the work, and they take a complete loss of heating and hot water in winter seriously. Beyond that, the fitness for habitation route lets a tenant go to the county court and ask for the works to be ordered and compensation awarded. While a part is on order it is reasonable to ask for temporary heating.

• Repairs done within a reasonable time of being reported in writing
• At least twenty four hours written notice before a non emergency visit
• Temporary heating or hot water where a repair is genuinely delayed
• A route to the council environmental health team if the landlord does nothing
• Compensation through the courts for a sustained period of disrepair

Plumbing charges taken out of a deposit

A landlord can only deduct for damage beyond fair wear and tear, for cleaning back to the standard recorded at check in, or for a repair the tenant caused and did not pay for. They cannot deduct for an item that reached the end of its life during the tenancy, and they cannot charge the price of a new one to replace something already old, a point deposit adjudicators apply strictly.

The evidence that wins is the check in inventory with dated photographs and the engineer's invoice describing what was found. A claim for a blocked drain succeeds when the invoice says wipes and fat in the branch from the flat, and fails when it says the pipe was scaled and the fall inadequate.

What settles the argument: the engineer's report

Whoever is right, the document that decides it is the report from the engineer who attended, and either side can ask for it. A useful report says what the fault was, what caused it, what was done, which parts were fitted, and what condition the surrounding installation was in. Wording such as cleared blockage invites a dispute later.

We attend these jobs regularly, with twenty engineers working across London, and the pattern is consistent. The disputes that drag on are the ones where nobody wrote down what was found. The ones that end in a day are where the invoice says a fatigued flexible tail under the basin had split, or a rope of wipes was drawn from the toilet branch. Ask while the engineer is still in the hallway, because it is harder to obtain a fortnight later.

• The fault, in specific terms, not a category
• The probable cause, and whether it is age, scale, corrosion or misuse
• What was done and which parts were fitted
• The condition of the surrounding pipework, valves and appliance
• Photographs, where the cause came out of the pipe
