In short
Who fixes leaks, radiators and cylinders in Harrow?
Leaks, blockages, cylinders and radiator faults across Harrow are everyday work for EliteShires Property Services, and water coming through a ceiling is reached the same day within opening hours, Monday to Saturday, with Sundays kept for emergency calls.
The exception is a boiler that has broken down. Boilers are not something we repair or fit, and you will hear that on the first call, which leaves you free to ring a heating engineer at once. From Kenton Lane, the town centre, Wealdstone, North Harrow and South Harrow are usually under fifteen minutes away. Much of the older stock still runs a cylinder and a cold tank in the loft, which means more joints and valves that can fail.
The full guide is on our Plumber & Plumbing Work page, and everything else we do locally is under landlord certificates and repairs in Harrow.

Plumbing in Harrow: what is different here
What plumbing problems are most common in Harrow's older houses?
The ones that come with age and alteration. Seven in ten Harrow homes were built before 1965, on Valuation Office figures, and most have had kitchens and bathrooms moved, extended or doubled since, with pipework added in stages and a conventional system with a cylinder and loft tank often left in place. That produces a familiar set of callouts: a weeping cylinder, a sticking ball valve in the tank, radiators that heat unevenly, and leaks at joints hidden behind boxing.
Outside, original clay drains and cast-iron soil stacks, where they survive, are approaching a hundred years old. We find the source before replacing anything, and if another repair would be poor value, we set out both options side by side.
How quickly can a plumber get to a Harrow emergency?
On the day you call, if it is within opening hours from Monday to Saturday; on a Sunday the line is open for emergencies only. Ring rather than email when water is escaping, and close the stopcock while you wait: in older terraces it is usually under the kitchen sink, by the front door or in the understairs cupboard. If it is seized, tell us.
If the diary will not get a plumber to you in time to matter, you hear that straight away and can ring another firm. Warn us about permit-only parking on your road, and say whether the water is coming through from a flat above, because shutting it off may depend on their door being opened.
What do Harrow's HMO standards expect from bathrooms and kitchens?
More than many landlords expect, and they set the brief for plumbing work in Harrow shared houses. Up to four sharers can manage with a single bathroom whose WC may be in the same room. At five, the council wants a WC with its own basin in addition to the bathroom, and from six to ten people, two of each. A WC outside the house does not count towards those numbers, and nobody should have to go more than one floor to reach a bath or shower. Each bath, shower and basin needs constant hot and cold water and a sealed splashback, 300mm high over baths and basins and full height in showers.
In the kitchen, one sink of at least 500 by 600mm with a drainer serves up to five people; above five, the table asks for one sink per four occupiers or part of four, though a dishwasher may be accepted in place of a second sink. Shared bathrooms wear faster, so we can work to an agreed spend threshold, fixing routine faults straight away and asking you above it.
Do you fit bathrooms in Harrow as well as repair them?
Yes. A bathroom refit or a new shower gets one written price before work starts, tied to a specification listing the suite, the fittings, the tiling area and anything left out. In a 1930s house that specification often has to allow for pipework in odd places, a floor that needs attention once the old suite is out, or a waste run that was never quite right, and we would rather put that in the quote than discover it halfway through.
Wet areas are tanked before tiling. If the boiler has to move or change to suit the new layout, that part goes to a heating engineer, because boiler work is outside what we do. Most refits take days rather than weeks, and you get a realistic programme at quote stage.
Who clears a blocked drain at a Harrow house?
Usually the owner, unless the drain is shared. Harrow Council clears road gullies but not drains on private property, which it says homeowners and landlords must clear themselves. Thames Water runs the sewers in Harrow, and since October 2011 it has also owned drains shared by two or more properties, plus a single home's drain once it leaves that home's boundary. So a blocked gully or inspection chamber serving only your house is yours, while a manhole that backs up for the whole terrace is probably Thames Water's.
We lift the covers, find where the water stands and clear what is on your side. If the blockage is in the shared run, you get photos and a note of which chamber is affected to send to Thames Water.
Do I need to tell Affinity Water before plumbing work in Harrow?
For some jobs, yes. Affinity Water supplies the borough, and under the Water Fittings Regulations certain installations need notice to the company, and its consent, before work starts. In Harrow the usual trigger is a water softener, because the supply is very hard by the Drinking Water Inspectorate's measure, which starts at 300 mg/l. Affinity's zone reports for 2025 give 360 mg/l for Harrow North, from a single sample, and readings of 298 to 443 mg/l, averaging 363, for Harrow South.
A softener that sends water to drain each time it regenerates is a notifiable fitting. So are a booster pump drawing more than 12 litres a minute, a bath of over 230 litres, and new supply pipe laid outside shallower than 750mm or deeper than 1,350mm. Affinity has ten working days to answer; if it says nothing, consent is treated as given. We raise the notice at quote stage so it never holds up the job.

Plumbing in Harrow: your questions
Not answered here? Call 0203 667 1333 and ask.
What decides the cost of a plumber in Harrow?
It depends on the kind of job. A bathroom refit or a new cylinder has its price settled in writing at quote stage, while a repair runs on an hourly rate with an estimate you agree first, and every part appears on the invoice. The rate is the same wherever you are in the borough. Time is what varies, and access drives it: a boxed-in pipe, an unboarded loft or a seized stopcock all add to it.
My loft tank keeps overflowing. Is that urgent?
It usually points to a sticking or worn ball valve, and while it is rarely a same-day emergency, it should not be left for long, particularly if the overflow runs onto the roof or into the loft itself. It is a routine repair that normally takes well under a morning. If water is getting into a ceiling, call us straight away.
Can you deal with a leak into the flat below?
Yes. First we find whether it comes from a pipe, a waste, or failed sealant round a bath or shower, since each needs a different repair. In a converted house or a purpose-built block, the source can sit on the boundary with communal pipework, and we will tell you which side of it the leak is.
Does Harrow's hard water shorten the life of taps and showers?
It adds to the wear. At around 360 mg/l, scale gathers in shower heads, thermostatic mixers, toilet fill valves and immersion elements, so a sticking valve or a shower with a weak, uneven spray is often furred up rather than broken. Descaling, or swapping the scaled part, is usually a short job. A whole-house softener needs Affinity's consent first, as explained above.
Could my older Harrow house still have a lead water pipe?
It could. Homes built before 1970 may still have lead supply pipes, the Drinking Water Inspectorate says, and Valuation Office figures put at least seven Harrow homes in ten in that age range, so unless yours has been renewed it is worth checking. Responsibility for the run between the outside stop valve and the house sits with the owner. We can trace it and replace it in plastic, and it is worth telling Affinity Water too, as it may replace a lead pipe on its side of the boundary.
