What Our London Repair Team Can Fix For You
Our engineers cover five core areas of plumbing repair — here’s what each one involves and how we can help.
Leak Detection & Repair
A leak isn’t always obvious. Water can travel along joists and pipes before showing itself as a stain or damp patch — sometimes nowhere near the actual source. Our engineers use specialist equipment to locate hidden leaks accurately and carry out a lasting repair, minimising disruption to your property. Early action saves you from significant structural damage further down the line.

Burst Pipe Repair
A burst pipe needs immediate attention. Left even a few hours, it can cause flooding, damage to electrics, and serious structural problems. Our engineers respond quickly to burst pipe callouts across London, isolating the affected section and carrying out a proper repair — not a temporary patch. If the pipe is beyond saving, we can advise on pipe replacement options too.

Tap & Faucet Repair
A dripping tap isn’t just annoying — a tap dripping once per second wastes over 5,000 litres of water a year. Whether it’s a worn washer, a faulty cartridge, or a tap that simply won’t turn off properly, we’ll fix it neatly and efficiently. We work with all tap types, from traditional pillar taps to modern mixer and thermostatic designs, in kitchens and bathrooms alike.

Toilet Repair & Replacement
A constantly running toilet, a weak flush, or one that fills slowly are all signs something isn’t right internally. Most faults come down to a worn fill valve, a faulty flap, or a cracked cistern component — all fixable on a single visit. Where repair isn’t viable, we’ll advise on the most suitable replacement and handle the full installation cleanly and to standard.

Water Pressure Issues
Poor water pressure makes showers frustrating and slows down everyday tasks. High pressure, on the other hand, puts unnecessary strain on your pipework and appliances. Our engineers identify the root cause — whether that’s a faulty pressure regulator, a partially closed stopcock, or a build-up of scale and debris — and carry out the right fix to restore consistent flow throughout your home.

Warning Signs You Shouldn’t Ignore
Plumbing problems rarely fix themselves — and waiting usually makes them worse. Here are six signs it’s time to call a professional:
- Damp patches or water stains on walls, ceilings, or floors — often pointing to a hidden leak
- Dripping taps or a constantly running toilet — wasting water and signalling worn internal parts
- Low or fluctuating water pressure throughout the property
- Discoloured or rusty water from taps — a sign of corroding pipes or a failing water heater
- Gurgling sounds from pipes or drains after use
- Unexplained rises in your water bill — often caused by a slow, undetected leak
If any of these sound familiar, book a repair online or give us a call — the sooner we look, the simpler the fix usually is.
Other Services You Might Need
Sometimes a repair uncovers a wider issue, and we can help with that too. If blockages are affecting your flow or drainage, our drainage services cover everything from blocked drains to sewer problems. For pipes that are past repairing, pipe replacement and relining is the logical next step. And if you’d rather stop problems before they start, an Annual Maintenance Contract keeps your plumbing in check year-round.

Frequently Asked Questions About Plumbing Repairs
How much does a plumbing repair cost in London?
The cost depends on the type of repair, the parts needed, and how long the job takes. We always provide a clear, written quote before we start work — so you know exactly what you’re paying with no hidden extras. For a specific price, book a visit online or call us directly.
How quickly can you fix a burst pipe?
We aim to reach you within [INSERT: e.g. 60 minutes] of your call in most parts of London. Once on site, we isolate the affected section immediately to stop further damage, then carry out a thorough repair. For anything urgent, our 24/7 emergency line is the fastest way to reach us.
Can you fix low water pressure in my home?
Yes — low water pressure is one of the most common repair requests we handle. Our engineers trace the cause, which could range from a partially closed stopcock or a failing pressure regulator to a scale build-up in older pipework. We carry out the right fix and test the pressure thoroughly before leaving.
Do I need to do anything before the plumber arrives?
For most repairs, nothing’s needed in advance. If you have an active leak or burst pipe, it helps to know where your main stopcock is — usually under the kitchen sink or near the water meter — so you can shut off the supply quickly if needed. Our engineer will walk you through anything else on arrival. For more answers, visit our FAQ page.
