Service Overview
Our residential plumbing service is part of our wider Specialist Services category and acts as the umbrella for all the plumbing work we carry out in homes across London. Rather than being a single fixed service, it’s our promise that whatever plumbing issue or project you’re dealing with at home, Catalyst can help — drawing on our full range of repair, installation, drainage and maintenance services.
Within residential plumbing, homeowners typically come to us for:
- Leak Detection & Repair – finding and fixing hidden or visible leaks
- Burst Pipe Repair – urgent repairs for burst or split pipes
- Tap & Faucet Repair – fixing drips, leaks and worn fittings
- Toilet Repair & Replacement – repairing or replacing toilets and cisterns
- Water Pressure Issues – diagnosing and resolving low or fluctuating pressure
- Bathroom Fitting – full or partial bathroom installations
- Blocked Drain Clearance and Blocked Toilet Unblocking – clearing household blockages
Leak Detection & Repair
What it is: Identifying the source of hidden or visible leaks within your home’s pipework, walls, or floors, and resolving them before they cause further damage.
Who needs it: Anyone noticing damp patches, unexplained water bills, musty smells, or the sound of running water with no obvious cause.
What’s included: Non-invasive leak detection where possible, pinpointing the exact location, and carrying out the repair with minimal disruption to walls, floors or fixtures.
Burst Pipe Repair
What it is: Emergency and planned repairs for pipes that have burst, split or cracked, often due to freezing, age or pressure issues.
Who needs it: Homeowners dealing with sudden water leaks, flooding, or pipes that have failed — particularly common during winter cold spells.
What’s included: Rapid response, isolation of the affected pipe to limit water damage, repair or replacement of the damaged section, and advice on preventing future bursts.
Tap & Faucet Repair
What it is: Repairing or replacing dripping, stiff, or leaking taps and faucets throughout the home.
Who needs it: Anyone with a tap that won’t turn off properly, drips constantly, or has become difficult to use.
What’s included: Diagnosis of the issue (washers, cartridges, seals or full unit replacement), repair or like-for-like replacement, and testing to confirm the fix.
Toilet Repair & Replacement
What it is: Fixing faulty toilets — running cisterns, weak flushes, leaks at the base — or replacing units that are beyond repair.
Who needs it: Households with a toilet that won’t flush properly, keeps running, rocks when sat on, or is leaking at the base or pipework.
What’s included: Diagnosis and repair of cisterns, flush mechanisms, seals and connections, or full removal and installation of a new toilet where replacement is the better option.
Water Pressure Issues
What it is: Diagnosing and resolving problems with low, inconsistent, or excessively high water pressure throughout the home.
Who needs it: Anyone experiencing weak showers, slow-filling appliances, banging pipes, or pressure that varies unpredictably.
What’s included: Pressure testing throughout the property, identification of the underlying cause (often pipework, valves or the mains supply), and the appropriate repair or adjustment.
Bathroom Fitting
What it is: Full or partial bathroom installations, from replacing individual fixtures to a complete refit.
Who needs it: Homeowners renovating their bathroom, replacing an ageing suite, or adapting a bathroom for accessibility needs.
What’s included: Removal of old fixtures, installation of new sanitaryware, taps, showers and pipework, and connection to existing or upgraded supply and waste systems.
Blocked Drains & Toilets
What it is: Clearing blockages from household drains and toilets that are slow-draining, gurgling, or backing up.
Who needs it: Anyone with a toilet that won’t flush away properly, sinks or baths that drain slowly, or unpleasant smells from drains.
What’s included: Diagnosis of the blockage location, clearance using appropriate equipment, and advice on preventing recurrence. For more stubborn or recurring issues, our CCTV Drain Survey service can identify underlying problems.

Why Professional Residential Plumbing Matters
Plumbing work in UK homes isn’t just about getting things working again — it’s about doing it safely, to the right standard, and in a way that protects your property and its value. Poorly fitted pipework or fixtures can lead to leaks, water damage, and costly repairs down the line, while gas-related work carries strict legal requirements around who can carry it out.
At Catalyst Home Services, our engineers are appropriately qualified for the work they undertake, with gas-related work carried out only by Gas Safe registered engineers. We follow current Water Regulations and Building Regulations guidance relevant to plumbing and bathroom installations, helping protect your home, your warranty, and your peace of mind. You can view our full credentials on our Licences & Certifications page.
