James went above and beyond to ensure I had heating and that my house was safe after my 40 year old boiler finally kicked the bucket and I had a gas leak over the Christmas period. My new boiler is fantastic. I would definitely use him again and recommend him to friends.

Fantastic service from James at Diamond Plumbing. Professional, efficient, and highly knowledgeable. I would absolutely recommend, and I will be using this service again.

We needed to get LP certification and the original guy was being super flaky. They came in so quickly and gave a fair price. Much appreciated

Job: new gas boiler. Petersfield. Overall an excellent service. Responded promptly to our query with a visit and quote. The job was done quickly, efficiently and as per the quote. It was not straightforward but James worked over and above to remedy all issues. We would not hesitate to recommend him.
