Client Feedback

“We have had another EV Charger fitted and once again the service provided has been excellent. We had to change the install date a few times due to delays in the delivery of the car and it was never a problem for Kate to accommodate. Jack who installed the charger was also excellent, happily moving items to enable him to do the work, doing a very tidy install, and then not leaving until everything was set up exactly as it should be and having briefed us fully on how to use it. Will happily use again without hesitation.”

“Polite, professional, and efficient service from all at Diamond Services. Both the initial installation of the car charger and then a house move-related uninstall & reinstall at the new property was seamless. I would definitely recommend.”

“Diamond Services is one of the contractors we use at Dragonfly Lettings for EICRs on rented properties. I’ve had nothing but good experiences with them- they are efficient, reasonably priced and extremely polite and professional. Would thoroughly recommend them, 10/10.”

“Diamond Services fitted LED lighting throughout our commercial premises and installed and certified a new fuse box. We had a couple of companies quote for the job and not only were Diamond services very competitively priced, but due to their highly trained staff they were able to complete electrical work that others couldn’t. They were professional, friendly, and worked around our needs so there was no downtime for the business. I would highly recommend Martin and his team (Joe & Jack).”

“Diamond Services has consistently provided us with an excellent quality of service over the past 5 years. Starting with the superb conversion of our agricultural grain barn with no previous electrical supplies into a veterinary practice, they have continued to sort out any of our many and varied requests in an efficient and professional manner. I would not hesitate to recommend them to anyone.”

Hannah Kelly, Wood Farm Vets

“I have been working with Diamond Services to manage a small portfolio of properties in the Norwich area and can not recommend them highly enough. They always offer a professional, high quality, and timely service. Looking forward to working with them regularly in the future.”

“We have worked with Martin and Diamond Services for many years on projects from fixed wire testing, small office refurbishments, breakdowns to complete infrastructure projects on some of our main laboratory buildings, and have always been very pleased with the professional and speedy service they provide. They offer a complete package, from estimating, site surveys, installations, testing, and servicing, which gives us the confidence of the quality and reliance of the work from start to finish.”

“We purchased an office building in need of renovation, and Diamond Services helped us to get our building back to a safe standard in no time all. We used Diamond Services once again when we came to extend our office space and will be using them again in our future projects. No job is too big or small. Time and time again we have been delighted with the cost, speed, and standard of works carried out. We would thoroughly recommend Diamond Services to any other local business like ourselves.”

Kerrie Farnan, Head of Projects, Lifeline24

“Diamond Services provided a professional, efficient, and polite service. From Martin who provided the quote and guidance to the electricians undertaking the install, this gave us the confidence that we had chosen a truly professional and efficient electrical contractor who we would not hesitate to use again.”
