Commercial Plumbing Services in London

A burst pipe closes a floor. A blocked washroom closes a unit. FS Group provides commercial plumbing services in London with two-hour emergency attendance, so the building keeps trading while the repair happens.

What we cover on a commercial plumbing contract

Water problems escalate by the minute. A leak above a suspended ceiling damages stock, IT equipment and finishes long before anyone finds the source, and every hour a washroom block stays shut is an hour the building is operating below capacity.

Our engineers work across live commercial buildings. Mains and distribution pipework, hot and cold water systems, unvented cylinders, booster sets, washroom installations, urinals, macerators, kitchen supplies and pressure faults.

Emergency callouts, scheduled servicing and remedial works run under one agreement, so the same team knows your risers, isolation points and access arrangements before anything goes wrong.

How we handle commercial plumbing works

Site walk
We visit, list the assets and agree what needs checking, how often, and at what cost.
Schedule set
The year goes in the diary upfront, with frequencies set per asset rather than per sit
Engineers attend
Your site history arrives with them. Small jobs get done on the visit, not raised as a second booking.
Report issued
Written report after every attendance covering what was done, what was flagged and what needs quoting.
LEAKS AND BURST PIPES
Water tracks a long way before it shows. Our commercial plumbing services in London cover leak detection, pipe repair and full section replacement, with isolation on arrival to stop the damage spreading. Ceiling voids, risers and buried pipework are traced without stripping out more of the building than the repair actually requires.

WASHROOM AND SANITARYWARE FAULTS
Blocked WCs, failed flush valves, leaking urinals and running cisterns take facilities offline and generate complaints fast. We repair, replace and install commercial sanitaryware, including macerators, sensor taps and automatic flush systems, and can phase washroom works so part of the block stays open throughout.
PRESSURE, FLOW AND HOT WATER PROBLEMS
Weak flow on upper floors, fluctuating temperatures and cylinders that cannot keep up usually point to booster sets, pumps or valves rather than the outlets themselves. We test the system, identify where the pressure is being lost, and repair or replace the plant causing it rather than treating the symptom.

KITCHEN AND BACK OF HOUSE SUPPLIES
Commercial kitchens run hard and fail loudly. Grease-laden waste lines, failed isolation valves, dishwasher and glasswasher connections, and hot water demand that outstrips supply all sit with us. Work can run outside service hours so the kitchen is back in operation before the next cover.

Trusted across London and the South East

Who we cover in London

Managed offices, retail and hospitality groups, housing associations, hotels, schools, healthcare premises and the facilities management companies covering them. Buildings where a plumbing fault becomes a tenant complaint the same morning.

Most clients hold a Priority Account, which fixes response times, agrees rates before the callout rather than after it, and keeps the same engineers on your sites. Over 25 years across London and the South East, more than 12,000 jobs a year, and over 100 commercial clients on the books.

What working with us actually looks like

We work in occupied buildings, so containment and clean-up are part of the job rather than an afterthought. If your site has permit, induction or out-of-hours access requirements, tell us at setup, and we will build them into how we attend.
Two-hour attendance
Emergency response across London, day or night, subject to availability.
Servicing scheduled upfront
Intervals set per unit, with dates in the diary a year ahead.
Parts held and sourced
Common failures carried on the van, obsolete parts traced rather than written off.
Documentation on completion
Gas safety records and service reports issued at the visit, not weeks later.
One contact across sites
Consolidated reporting and invoicing, whatever the portfolio size.

Why the first hour decides what the repair costs

Most of the spend on a commercial water escape is not the plumbing. It is the ceiling, the flooring, the stock underneath and the trading time lost while it dries out. A fast isolation turns a serious insurance claim into a straightforward repair.

That is what the response time is for. Our commercial plumbing services in London are built around getting an engineer on site within two hours, with Priority Account holders working to fixed response times rather than availability on the day. The engineer attending already knows your isolation points, because the same team covers your scheduled work.

Frequently asked questions

How fast can you get a commercial plumber to us?
We aim to attend within two hours across London, subject to availability, 24 hours a day. Priority Account holders get fixed response times written into the agreement, which matters when a leak is actively damaging the building.
What does your commercial plumbing cover?
Mains and distribution pipework, hot and cold water systems, unvented cylinders, booster sets and pumps, washrooms and sanitaryware, macerators, kitchen supplies and pressure faults. Our commercial plumbing services in London run across offices, retail, hospitality, education and healthcare sites.
Can you work without closing the building?
Usually, yes. We isolate the affected section rather than the whole system where the pipework allows, contain the working area, and phase washroom or kitchen works so part of the facility stays in use throughout the repair.
Do you attend outside working hours?
Yes. Emergency cover runs 24 hours a day, 365 days a year. Planned works can also be scheduled evenings or weekends, which suits retail units, restaurants and offices where daytime disruption is not an option.
Do you handle leak detection?
Yes. We trace leaks through ceiling voids, risers and buried pipework before opening anything up, so the repair stays contained. Finding the source properly avoids the repeat callouts that follow when the visible damage gets patched instead.
Can you cover multiple sites under one agreement?
Yes. Rates, response times and any scheduled works are agreed once and applied across the portfolio. Each site is reported individually, but you get one account contact and consolidated invoicing rather than separate paperwork per property.
Do you work for facilities management companies?
Regularly. We provide overflow capacity and specialist support for FM providers and larger maintenance contractors across London, working to their reporting formats and response obligations. Unbranded vans are available where the end client relationship requires it.
