Plumbing issues can happen unexpectedly — and in a busy city like London, they can quickly escalate into expensive repairs or major water damage if not dealt with promptly. As professional plumbers operating across London 24/7, we regularly attend callouts for leaks, burst pipes, faulty toilets, boiler pressure issues, and blocked drains.
In this guide, we break down the most common plumbing problems London homeowners face, the warning signs to watch for, and how expert plumbers solve them quickly and safely.
⭐ 1. Leaking Pipes & Hidden Leaks
Leaks can occur behind walls, under floors, in bathrooms, kitchens, or central heating pipes. Early signs include:
- Dripping sounds
- Damp or mould patches
- Boiler pressure dropping
- Wet areas on ceilings or floors
- Unexpectedly high water bills
Minor leaks often become major ones if ignored, so fast professional attention is crucial.
⭐ 2. Burst Pipes
Burst pipes are one of the most urgent plumbing emergencies. They can cause extensive flooding within minutes.
Common causes:
- Frozen pipes
- High water pressure
- Old pipework
- Corrosion or incorrect installation
A professional plumber will isolate the pipe, carry out a safe burst pipe repair London, and check the system to prevent future bursts.
⭐ 3. Faulty Toilets
We repair hundreds of toilet issues each year, including:
- Constantly running toilets
- Blocked toilets
- Weak flush
- Leaks from the toilet base
- Overflowing cisterns
These problems are usually caused by worn parts, scale build-up, blockages, or a faulty fill valve — but are quick to fix when diagnosed properly.
⭐ 4. Boiler Pressure Loss
If your boiler keeps losing pressure, it’s usually a sign of:
- A leak on the central heating system
- A faulty expansion vessel
- Air in the system
- A problem with the pressure relief valve
Many homeowners repeatedly top up their boiler, not realising this can cause long-term damage. A professional plumber will find and fix the cause, ensuring the system runs safely.
⭐ 5. Blocked Sinks, Baths & Showers
Hair, grease, food waste, and soap scum cause slow drainage and unpleasant smells. If left untreated, blockages often worsen and affect other parts of the plumbing system.
While basic plunging may help, deeper blockages require:
- Mechanical unblocking
- High-pressure jetting
- Pipe cleaning
⭐ 6. Leaking Taps & Fixtures
A dripping tap can waste hundreds of litres of water per year. The usual causes include:
- Worn washers
- Faulty cartridges
- High water pressure
- Old tap mechanisms
Our engineers repair or replace taps quickly and affordably.
⭐ 7. Low Water Pressure
Low pressure affects showers, taps, and appliances. Common causes:
- Partially closed valves
- Blocked aerators
- Leaks
- Limescale build-up
- Mains supply issues
A plumber will test the system to find the exact cause and restore normal pressure.
