“At ClaudeComputing we like to ensure that our clients are getting the best from their IT System, even if some components are provided by a 3rd party company.

This means that we may liaise with service providers on our client’s behalf.
Unfortunately, some companies have little knowledge about the systems they provide and support.

So, when one of my clients were experiencing poor Internet reliability and the service provider was unable improve the service, I contacted Graham Compton from Cavendish Communications.

Graham provided a new line and service at a cheaper rate than the old provider. The Internet connection has been stable and problem free for over 2 months.
Through Graham and his knowledge of telecommunications I was able to advise my client on more cost saving actions which would help to streamline the system.

It is a breath of fresh air being able to speak with a supplier who knows what they are taking about.

Claude Computing will continue to use Cavendish Communications as its preferred Business Telecommunications Supplier.

Graham thank you for all your help and knowledge. ” – Claude Martin-Currie, Director

Claude Computing

“When one of our telephones stopped working and couldn’t be replaced within the current set-up, we realised that a system overhaul was long overdue. We approached several companies for quotes and Cavendish was unquestionably our preferred company. We like to use local companies wherever we can, but Cavendish also had the “can-do” attitude that we like and costs were very competitive.

We needed a good, fast broadband service as well as an integrated telephone system. Cavendish explained the different possibilities and costs and then proceeded to set up the system with minimal input from us whilst keeping us informed throughout. We wanted to set up in the main office first with outlying departments brought in as needed. This all proceeded to plan which made life much easier for all involved.

We now have a system that can be easily upgraded when necessary and, crucially, works well!” – Julie Eason, Finance Manager

“After months of failed attempts from other companies to provide us with an installation of our new office phone system, we called on Graham Compton of Cavendish Communications. From the very start Graham was professional and spoke confidently of his teams’ abilities.

After a very successful meeting to discuss our requirements, Graham started the ball rolling. We came across a few hurdles along the way, and each time Graham was at the end of an email or phone call. The customer service that he provided us was outstanding and has continued to provide the same service consistently.

We are now lucky enough to have a fully working professional office phone system which provides our customers with a smooth transition from phoning us to having their questions answered promptly.

I cannot fault Graham and his team for going above and beyond to provide us with the exact service we were after.

I will have no hesitation, to recommend Graham and Cavendish Communications, to any business with a need to upgrade an existing or install a new system.” – The Heatwize Team

They presented a range of cost-effective options and supported us in the process of selecting the Panasonic solution and then ensured the installation was completed on time and within the budget.

The engineer attended site before we started work which was very helpful so it didn’t interfere with our working day too much. He worked quickly and tidily and explained exactly what he was doing. We have not had a problem since he left. Cavendish are quick to resolve any issues that we have – I would not hesitate in recommending them.

A last minute cry for help during a very busy period for the Cavendish engineers was handled promptly and efficiently. They look after us very well which is very much appreciated. The engineers and our account manager are always very knowledgeable, willing to help and probably smile through gritted teeth when we pile on the pressure. This latest cry for help was a good example of the result of having a good working relationship and the professionalism of the team.
