Forgotten after.

About the firm
A small firm, kept small on purpose.
Bill Holloway started fixing lead pipe out of a yard off Holloway Road in 1978. His son took the vans over in 1996; his granddaughter runs the office now. We have never been more than nine people, because the moment a plumbing firm gets large the person who quoted your job stops being the person who does it.
We work across north and central London — mostly Victorian terraces, mansion flats and the occasional new build that was plumbed in a hurry. Half our work each year comes from someone we did a job for a decade ago.
Kate Holloway runs the office and still quotes every job herself.
22 mm copper · 15 mm branch · soldered, not pushed · every joint pressure-tested at 6 bar
What we do
Four things, done properly.
Boilers & heating
Replacements, system upgrades, powerflushing and annual servicing. Gas Safe registered engineers, benchmark logbook completed on the day.
Service £85
Leak detection
Thermal imaging, acoustic tracing and pressure testing before anybody lifts a floorboard. We find it first, then open the smallest hole that will do.
Diagnosis £95
Underfloor heating
Wet systems in screed or low-profile boards, zoned and balanced properly so the far corner of the room is the same temperature as the door.
From £1,950 a room

What people say
In their own words.
612 reviews since 2014, collected on Google and Checkatrade. These three are recent and typical.
Came out on a Sunday for a burst feed under the floor, found it in twenty minutes with a camera rather than taking the boards up. Quoted, then charged, exactly what he said.
Eleanor R. · Highbury N5 · March 2026
Second bathroom they have done for us, eleven years apart, same family. The first one has never given us a day of trouble, which is the only review that really counts.
David and Sam O. · Barnsbury N1 · January 2026
Three firms quoted for the heating. Holloway were not the cheapest and were the only ones who explained why the far radiators were cold instead of just offering a new boiler.
