 Customer Testimonials



Citizens Advice – Broxtowe 

We have today renewed our contract for a 5 year deal as CDI provide excellent customer service. They have always responded to our problems with solutions and we look forward to working them over the coming years.

CDI currently look after our telephone systems but we are also looking at using them for a new broadband system we need installing. I would recommend them to any business.

Chief Executive

Citizens Advice




Jewson Limited

The Support from the CDI head office was excellent. With a dedicated contact in Jim Clarke and scheduling support from Lisa Foster the rollout ran ahead of schedule and to the ever important project factors of agreed cost and quality. The cabling stage of the chip and pin project worked so well that we have changed the rollout stage to make use of CDI’s skills to assist in installing the devices.

Jewson Limited




Boeing UK 

Thank you formally for your supreme efforts in helping us to complete this project in time for the August move which allowed the workforce to seamlessly transfer premises without impacting their operation. Your subsequent support once they had moved in was also much appreciated.

Working Links 

The ability to access information that identified peaks and troughs in demand subsequently enabled us to allocate more people to take calls at our busiest times, and mean staff are not sitting unused during quieter periods.

“We’ve worked so closely with CDI over the past 12 years that the professionals they’ve assigned to work on our account very much feel like part of the Working Links team. It’s reassuring to know there is always an expert on the other end of the phone we can ring should we need anything.”

Head of Customer Services





CDI came recommended to Jewson as a quality provider with competitive pricing, so we had high expectations. I can honestly say our expectations were more than met.

Senior Network Analyst




Britannia Building Society

It was imperative to engage with a business partner who could meet our requirements, specifications, budgets and deadlines. I am delighted to say that CDI was big enough and flexible enough to fulfil all our needs. Communication with CDI staff and engineers was first-class and their speedy reaction to those inevitable unplanned changes made the installations a lot easier to manage.”

Warwickshire Police HQ 

Thank you and all of the CDI team for their work. I can only praise all of your guys’ efforts with all the constant changes and extras. So once again thank you, Mick and all the guys for your work under somewhat ‘trying’ circumstances! Look forward to working with you in the future.”

Justice Centre Programme




Egg Plc

“I have worked with various cabling contractors over the years and was very impressed by the thoroughly professional approach of CDI. The Holborn installation went extremely smoothly and they were very adaptable when it was required. I applaud the approach of the project management team for delivering a superb installation.”

IT Project Manager




Hasbro Interactive 

“We were absolutely thrilled with the service we have received from CDI. They have worked very hard to complete the implementation within tight deadlines and to an exceptionally high standard. I was particularly impressed with their dedication and availability – I knew we could contact someone for advice at any time.”

Quality Assurance Manager




Tussauds Group London 

“The upgrade of our network infrastructure, installed by CDI, has made the administering of networks more efficient and has improved the speed of our networks dramatically. We are very impressed with the high standard of installation and the commitment and support offered by CDI.”

IT Manager




Beneficial Bank

“Just a quick note to compliment your staff on excellent work at our branches. I refer particularly in this instance to Pete Elvins, his attitude and helpfulness is a credit to your company. It is extremely useful that we have access to someone whom is able to work off his own initiative, and is willing to help us with things that are not always part of his remit”.

Network Manager





“As the project timescales were tight, I was unable to provide a full list of requirements prior to installation dates and quite often I have rung Pete Elvins with unforeseen changes and your engineers have always been able to accommodate them with no fuss. I have also received numerous compliments from our branch offices with regard to the conduct and workmanship of your engineers.”

Senior Communications Consultant




Cadbury Beverages Limited 

“and record on paper that your engineers, Colin Brown and Gary Ansell, carried out this job in a most efficient and professional manner. Nothing was too much trouble for them – the work was completed on time and they cleaned up on completion of the job. In fact, they left the offices in a much cleaner condition than they found them, which was very much appreciated.”

Administration Manager




NHS South Birmingham 

“I would like to express my thanks to you for the work carried out within the short timescales given. Would you also, pass on my thanks to Graham and his team for their speed and diligence during the installation, especially in the more sensitive areas within the Psychiatric Unit.”
