“Martin and his team do a great job and are a pleasure to work with in our new and exciting venture at OakVilla Restaurant and Distillery.”

Shaun Hancke, OakVilla 

“We phoned up as we were worried about our light switch and alarm system wiring. They sent out Jack the next day for a free look at the issue. He came adhering to full COVID guidelines I.e mask and social distanced etc… He quickly tested the issue we had and identified the issue quickly. We are so pleased with the fast, professional and friendly service which made us feel safe.”

Iain Mills

“A great installation job that required smart thinking and problem solving due to age of house. End product is visually extremely pleasing and engineer was clean, tidy and polite. Top work!”

Paul Halfpenny

“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 contracted Diamond Controls for a commercial fit-out for my factory. The quality of work was first class and work was delivered on time and in budget. I will certainly be using them on my next project and would strongly recommend Iain and his team to anyone.”

“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.”
