Plumbing Services

Leak Detection & Repair

A hidden leak can quietly cause thousands of pounds of damage before you even notice it. We use specialist equipment to locate the source accurately — without unnecessary drilling or disruption — and repair it properly the first time. Learn more about our leak detection and repair service.

Burst Pipe Repair

A burst pipe can cause serious water damage within minutes, so fast action matters. Whether it’s a frozen pipe in winter or age-related corrosion, our team arrives quickly to isolate and repair the damage before it spreads. Find out more about our burst pipe repair service in London.

Tap & Faucet Repair

A constantly dripping tap wastes more water than most people realise and pushes up your bills over time. We repair or replace faulty taps throughout your home, from kitchen mixers to bathroom basin taps, using quality parts built to last. See the full details on our tap and faucet repair service.

Toilet Repair & Replacement

From a running cistern to a cracked pan, toilet problems are disruptive and rarely fix themselves. We diagnose the fault quickly and carry out a clean, efficient repair or full replacement with minimal fuss. Find out more about our toilet repair and replacement service.

Water Pressure Problems

Poor water pressure makes showers frustrating and daily tasks take longer than they should. We identify the root cause — whether it’s a blockage, a failing valve, or a wider supply issue — and restore your water flow properly. Read more about how we tackle low water pressure issues.

Drainage Services London

Drainage problems tend to go from inconvenient to urgent very quickly. Our drainage services in London cover everything from a slow-running sink to a collapsed sewer line, with a team ready to respond fast.

Blocked Drain Clearance

A blocked drain is one of the most common household problems — and one of the most unpleasant to deal with. We clear blockages efficiently using the right tools for the job, leaving your drains flowing freely again. Find out more about our blocked drain clearance service.

Blocked Toilet Unblocking

A blocked toilet needs sorting out straight away, and it’s not always something a plunger can fix. Our team arrives promptly, identifies the cause, and clears it cleanly and professionally. Learn more about our blocked toilet unblocking service.

CCTV Drain Survey

A CCTV drain survey involves passing a small camera through your drain system to inspect it from the inside — giving us a clear picture of any cracks, blockages, or root intrusions without digging anything up. It’s the smartest way to diagnose recurring drainage problems accurately. Discover how our CCTV drain survey service can save you time and money.

Sewer Line Repair

A damaged sewer line is a serious issue that needs professional attention without delay. We repair and reinstate sewer lines using proven methods that minimise disruption to your property and garden. Read more about our sewer line repair service.

Plumbing Installation Services

Whether you’re renovating a bathroom, replacing an ageing boiler, or building a new property, good installation work makes all the difference long-term. Our installation services are carried out by experienced plumbers who take pride in a clean, reliable finish.

Bathroom Fitting

A new bathroom is one of the most rewarding home improvements you can make, but it needs to be planned and fitted properly to last. We handle everything from plumbing rough-in to final fixtures, working to your brief and timeline. Learn about our full bathroom fitting service in London.

Water Heater Installation

If your water heater is old, unreliable, or undersized for your household, upgrading it makes an immediate difference to your daily comfort. We supply and install a range of water heaters suited to different home sizes and budgets. Find out more about our water heater installation service.

New Build Plumbing

Getting the plumbing right on a new build is critical — mistakes at this stage are costly to fix later. We work with developers and self-builders across London to deliver first and second fix plumbing that meets all current building regulations. Read more about our new build plumbing service.

Pipe Replacement & Relining

Old, corroded, or undersized pipes affect water quality and pressure throughout your home. We replace or reline pipework using modern materials that are built to last decades, with as little disruption to your walls and floors as possible. Learn more about pipe replacement and relining.

Residential Plumbing

Your home deserves a plumber who treats it with care and respect. From routine maintenance visits to full property plumbing overhauls, our residential plumbing service covers everything a London household could need.

Annual Maintenance Contracts (AMC)

Reactive repairs are necessary sometimes, but planned maintenance is almost always cheaper, less disruptive, and better for the long-term health of your property. Our Annual Maintenance Contracts give you scheduled, professional upkeep throughout the year — so problems are caught early and your plumbing systems stay in top condition.

Residential AMC

Our Residential AMC gives homeowners scheduled maintenance visits, priority response times, and the reassurance that a trusted team is keeping an eye on things year-round. It’s the easiest way to protect your home and avoid unexpected bills.

Commercial AMC

For landlords, managing agents, and business owners, our Commercial AMC ensures your premises meet compliance standards and your plumbing infrastructure is regularly inspected and maintained. We work around your operating hours to keep disruption to a minimum.

Planned Preventive Maintenance (PPM)

Planned Preventive Maintenance (PPM) is a structured programme of scheduled inspections and servicing designed to prevent failures before they happen. It’s particularly valuable for commercial properties and landlords managing multiple units, where an unexpected breakdown can have a significant knock-on effect.
