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!
