🔧 Specialist Vaillant Boiler Repairs in SW3, SW5, SW7 & W8
If your Vaillant boiler is showing a fault code, underperforming, or has stopped working entirely — don’t leave it to guesswork. At RARE Plumbing London, we deliver fast, precise Vaillant boiler repairs in Kensington & Chelsea, using genuine parts and the latest diagnostic equipment.
From grand homes in Holland Park, to smart apartments near Sloane Square, to commercial premises across South Kensington, we understand the heating demands of high-value properties — and we fix them with care and discretion.
🛠️ What Vaillant Faults Do We Repair?
We fix all domestic and commercial Vaillant models, including ecoTEC, ecoFIT, and ecoMAX.
Here are common fault codes we repair:
• F22 – Low Water Pressure: We repressurise the system and check for hidden leaks or expansion vessel issues.
• F28 / F29 – Ignition Failure or Flame Loss: We inspect the gas valve, ignition electrodes, and test the flue for blockages.
• F75 – Pump or Pressure Sensor Fault: Often triggered after radiator bleeding. We diagnose and replace faulty pumps or sensors.
• F62 – Gas Valve or PCB Error: Our engineers test and replace the failing component with Vaillant-approved parts.
• F76 / F83 – Heat Exchanger Overheat or Flow Issues: We check circulation, clean the heat exchanger and inspect flow sensors.
• F20 – Boiler Overheating: This could signal a limescale buildup or circulation fault — we’ll find and resolve the root cause.
💬 Not sure what the code means? We’ll talk you through it — no jargon, just clear advice.

🔧 When a Repair Isn’t Worth It
We’ll always be honest: sometimes it’s better to replace than repair. If your Vaillant boiler is:
• Over 12–15 years old
• Repeatedly breaking down
• Corroded or scaled internally
• Becoming uneconomical to run or maintain
We’ll walk you through replacement options tailored to your home or property — without pressure.
