🔧 Vaillant Boiler Repairs in Knightsbridge

Discreet, Specialist Heating Support for SW1 Homes & Businesses

If your Vaillant boiler has failed or is showing an unfamiliar code, you’re in the right place. At RARE Plumbing London, we offer trusted, specialist Vaillant boiler repairs in Knightsbridge, with the experience to support both domestic and commercial systems across SW1.

Whether you’re dealing with low pressure in a penthouse on Hans Crescent, a fault code in a mews house near Brompton Road, or managing a commercial system in a boutique hotel, we provide prompt, discreet service tailored to your space and expectations.

🛠️ Common Vaillant Faults We Fix in SW1

From compact flats to complex commercial systems, we’ve resolved every major Vaillant fault code and performance issue. These include:

F22 – Low Water Pressure

We’ll safely repressurise your system and inspect for pressure loss or expansion vessel failure.

F28 / F29 – Ignition or Flame Loss

Caused by blocked flues, failed ignition components or gas supply issues — we’ll trace the root and restore full function.

F75 – Pump or Sensor Fault

Circulation issues are common in older properties and large systems. We test, replace or balance your pump and sensors accordingly.

F62 – Gas Valve / PCB Faults

If your boiler is behaving erratically, we’ll diagnose and replace the necessary internal components — no guesswork involved.

F76 / F83 – Overheating or Temperature Imbalance

We resolve heat exchanger scaling, faulty thermistors, or incorrect pump speeds that lead to these recurring codes.

💬 Not sure what your boiler’s error code means? We’re happy to explain it in plain English before we attend — just give us a call.

Happy Customers

“From the moment I called RARE Plumbing, I felt like I was in safe hands. They arrived on time, explained everything clearly, and fixed our boiler the same day with zero mess. It’s rare to find tradespeople this professional — I wouldn’t hesitate to recommend them.”
Amelia D., St John’s Wood
We had a problem with our boiler and complex heating system that other plumbers refused to touch. Paresh took it on, and fixed it very quickly. The visit was swift and easy, and he was very sensitive to our shielding requirements.
Michael Quicke
Having previously used Rare to do a full system installation, including new heaters, storage tank, new boiler install, bathroom fit & kitchen appliance install and new piping throughout the home, I called upon them again to service our boiler this winter.
Amit Halai
Paresh is unusual for a London tradesman -- he comes when he says he will come, he charges what he says he will charge, and the workmanship is always first class. I cannot recommend him highly enough.
James Robertson
Helped me with underfloor heating issue - I am so lucky to have found them! Great customer service, so knowledgeable - can't recommend them highly enough.
Becky B
I called Rare on Christmas Day with an urgent boiler problem. The team was very responsive, professional and polite - the issue was fixed quickly and fortunately they saved us from spending Christmas in a cold home with no warm water! Thanks again!
