I arranged with George to service my boiler . He turned up as agreed and was very professional . He is very knowledgable and we have arranged for other works to be done by him . Would highly recommend

Great tradesmen. Arrived on time and done all the work to a fantastic standard with minimum of fuss. Also cleaned up completely afterwards. Will definitely use again.

My boiler was making lots of noise need to change some part diamond Ltd done the job really good on the time he didn't let me down I'm really happy with service

Very professional company, the renovation was of top specification, they were reliable and always cleaned up every evening before they left. They communicated at every stage keeping me up to date with timings. They used quality products and the finish of the work is of a very high standard. They were always contactable and were professional and polite at all times. I am now going to use them again to complete a refurbishment of my new property. I would definitely recommend Certified Diamond Ltd for any building works.

George and son are highly trustworthy and competent. If it wasn’t for them we would not have the stunning bathroom and cloakroom we have, other peoples work would have haunted us with leaks and ineffectiveness and most importantly they are decent people (father and son) with huge integrity - very rare in this day and age, especially in the building trade. Thank you for helping us out of what can only be called a cluster mess up of problems. Forever grateful
