Plumbers trusted by landlords, councils and businesses

Plumbers who stop the water, then find where it came from

Our plumbers work in houses, flats, shops, offices and managed blocks across London, for a family firm that has been running since 1998.

Most plumbing calls start with water where it should not be: under a sink, through a ceiling or around the base of a toilet. The plumber isolates it first, then traces the joint, valve or fitting that let go, so the repair holds.
Plumbing and drainage often meet at the same fitting, a basin that drains slowly or a toilet that rocks, and the same team covers both, so nothing gets handed on to another firm.

Plumbing services we carry out in London

Six kinds of plumbing work cover almost every call. Tell the help desk what you can see and they will send the right plumber.

Which plumbing problem do you have?

Start with what you can see. Each of these has a usual cause, and the plumber confirms it before any work starts.
Burst pipes
Plumber tightening a joint on a water pipe
Water spraying or pouring from a pipe, often after a freeze or a knock. Turn off the stopcock first, then call, and the plumber cuts out the split section and joins in new pipe.

Leaking taps
Plumber repairing a basin tap
A drip from the spout usually means a worn washer or cartridge, and water round the base points to a failed seal. Both are quick repairs, and a tap past saving is replaced.

Low water pressure
Plumber checking the supply pipes under a basin
If next door has weak flow too, the supply is the likely cause and the water company is the call. If it is just you, look at a part-closed stopcock, a failing valve or scaled pipework.

A toilet that keeps running
Plumber repairing a toilet
Water trickling into the pan, or a cistern that refills on its own, points to a worn fill valve or flush seal. The plumber replaces the part in one visit.

Water under the washing machine
Plumber working on the waste pipes in a kitchen cupboard
Usually a perished hose, a loose connection or a waste pipe backing up. The plumber fixes the plumbing side, and a fault inside the machine goes back to its manufacturer.

A damp patch with no obvious leak
Plumber tracing pipework along a wall
Damp on a ceiling or wall, or a water meter that keeps turning with every tap off, means water is escaping where you cannot see it. The plumber traces it back from the stain to the fitting.

Leak repair
Had a visit this morning to repair a leak which other contractors had failed to fix for over a month now. I was kept in the loop about the time they would be arriving. They were punctual, polite and even tidied up after themselves. They also offered to report other issues in the household for me. Thank you so much

Bathroom plumbing
To say Chris didn’t go above and beyond will be a huge understatement. He was relentless in his approach to try and solve my plumbing issues in my bathroom even dropping in on a Saturday as he was passing as he had an idea. Fixed all the issues with candour and professionalism. They don’t make tradies like this anymore.

Felix and Cameron were fantastic! They arrived promptly this morning to handle some piping work, and I couldn’t be more impressed. They were quick, efficient, and highly professional, getting the job done smoothly without any hassle.

Beyond their technical skills, they were also very friendly and respectful, making the whole experience stress-free. It’s great to see such dedication to quality service. I’ll definitely be using their services again and would highly recommend them to anyone in need of reliable plumbing work!

We were first referred to FS and were immediately impressed by their professionalism and prompt communication. Since then, we’ve continued to entrust them with a significant amount of our plumbing and drainage work. They offer excellent value, are consistently reliable, and their out-of-hours service has been particularly impressive. Highly recommended.

I have used FS several times for drainage and plumbing issues
They are efficient both in ongoing communication, carrying out the work and reporting thereafter. Their prices are very competitive.

The communication aspect is really helpful as you can always get an update on likely time of arrival and 30 minutes before arrival you receive a notification task. Therefore you don’t have to hang around all day waiting.

The people employed to work for the company are all competent, helpful and very polite

Find your stopcock before you need it

The stopcock shuts off the water to the whole property. It is usually under the kitchen sink, in a cupboard near the front door or where the supply pipe comes up through the floor, and in a block of flats it can sit in a communal cupboard or riser.

What you can expect on every plumbing job

The same terms apply whether it is a dripping tap or a ceiling coming down. See our rates →
No call-out fee
No call-out charge, no ULEZ or congestion charge and no premium for a two-hour emergency response. You pay for the time on the job, by the half hour.
Six-month workmanship guarantee
Every completed job carries it, and the help desk will send you a copy of the terms whenever you ask.
SSIP accredited
Our health and safety accreditation is the one councils, housing associations and facilities teams usually check before letting a contractor on site.
Drains and plumbing in one visit
A slow basin or a leaking soil pipe can be both jobs at once, and the same team handles each side of it.

Plumbing for landlords, letting agents and facilities teams

A leak in the flat above a shop, a cistern running all weekend in an office washroom, a void property that needs its water back on before the next tenant moves in.
Landlords with whole portfolios, housing associations, councils and FM companies call us for plumbing, and the same team covers the drains, so one call sorts both.
On a Priority Account, every property gets faster response, one named contact and contract pricing.

How our plumbers deal with a leak

Four steps, in this order, on every leak we attend.
Isolate the water
The supply goes off at the stopcock or the nearest isolating valve first, so the damage stops spreading before anything else happens.
Find where it starts
Water runs along pipes and joists before it shows, so the stain on the ceiling is rarely the source. We trace it back to the joint or fitting that failed.
Repair or replace
A worn washer or a weeping joint gets repaired. A corroded length of pipe or a cracked fitting gets replaced, and you hear which one before the work starts.
Test before we leave
The water goes back on, the repair is checked under pressure, and your report shows photos from before, during and after the job.

While you wait for the plumber

If water is coming through, these four things limit the damage before we arrive.
Turn the water off
Turn the stopcock clockwise until it stops. If the leak is from one tap or toilet, the small isolating valve on its pipe shuts off that fitting alone.
Keep water off the electrics
If water is near sockets, light fittings or the fuse box, switch the power off at the main switch and leave it off until it has been checked.
Empty the pipes
With the stopcock off, open the cold taps in the bath and basins and flush each toilet once. Less water left in the pipes means less coming through the ceiling.
Photograph the damage
Take photos of the leak and anything it has soaked before you move it. Your insurer or landlord will usually ask for them.

Frequently asked questions

Do you charge a call-out fee?
No. There is no call-out charge and no ULEZ or congestion charge. Time on the job is billed in half-hour blocks, and you hear the rate from the help desk before a plumber is sent. Weekend rates apply on bank holidays.
Do you fix burst pipes the same day?
Yes, as an emergency. We aim to reach you within two hours, subject to availability. The plumber isolates the supply, cuts out the damaged section and replaces it, then checks the joints under pressure before leaving.
Can you find a leak I can't see?
Often, yes. The plumber works back from the stain or the damp patch to the joint or fitting that failed. If it sits under a floor or behind tiles, you hear how much needs opening up before anything is lifted.
Why does my toilet keep running?
Usually a worn seal on the flush valve, or a fill valve that no longer shuts off, so water trickles into the pan all day. Both are parts a plumber can replace in one visit, and it is worth doing soon on a water meter.
My water pressure dropped suddenly. Should I call a plumber?
Ask a neighbour first. If theirs has dropped too, it is likely the water company's supply, and they can tell you about any works nearby. If it is only your property, a hidden leak, a part-closed stopcock or a failing valve is more likely, and that is a job for us.
Can you plumb in or move an appliance?
Yes. We plumb in washing machines and dishwashers, fit outside taps, and move the supply and waste pipes when a kitchen or utility layout changes.
Who pays to fix a leak in a rented home?
In most tenancies in England and Wales the landlord must keep the water pipes and sanitary fittings in repair, under section 11 of the Landlord and Tenant Act 1985. Tell your landlord or agent in writing straight away and send them photos.
What if the leak comes back after a repair?
Call the help desk. Our six-month workmanship guarantee covers it, so a repair of ours that fails in that time is ours to put right.
