James is very professional and prompt! Accepted a quote and the next day he fitted me a new boiler, lovely chap and very knowledgeable, I would recommend diamond plumbing to anyone.

James came in to help us, as our old boiler packed up. Very professional, reasonable and honest person with quality work. Hard to get people who pride themselves in their job and service. James is a rare find. A person who is dedicated and above all never let's you down. Thank you!

James was absolutely brilliant when we called last week regarding a leaking boiler. He came out to see us in the evening and was able to spot the problem in minutes. James was then able to fit us in the next day to replace the old boiler, get a new one fitted and even fixed a few other plumbing problems we had. Prompt and professional, we would 100% recommend him. Thank you!

New boiler installed perfectly. Efficient and hard working. Even replaced some old pipework and no mess left behind at all. Cheers.

James arrives when he says he will, he's thoroughly knowledgeable, and fully focuses on the job in hand. Very pleasant and helpful - even took away the obsolete tanks in my loft (several of them, accumulated over years). Thank you, James! My new combi system will make a big difference this winter. I'd thoroughly recommend Diamond Plumbing to anyone.
