The #1 choice for UK businesses
“We have used One Cloud for well over 10 years. Their service levels and attention to detail are excellent."
Jeremy Chadwick Yellowdot
Highly recommended for their excellent and very personal customer service. David and Fred have looked after us whilst on-boarding and ensured the new telephone system caters to all our needs as a small business.
Seena Kalsi Doorstep Pharmacy
Excellent work from David and the whole team, very professional and solved our WiFi and telecommunication issues. During lockdown there was heavy demand on our Internet, it was crucial to have a reliable broadband for our residents to keep in touch with loved ones. Highly recommend their company as we now have a better WIFI connection throughout the homes.
Amit Parkash SPC Care Homes
These guys know their stuff and have helped my company out no end. They have gone above and beyond to get things switched over from my previous telecoms supplier and it was totally seamless.
James Desmond Liphook Auto Services
I have worked with One Cloud Telecom since they started. I am a reseller of Telephony and broadband services and my very first concern was to ensure that, before even costs, support would be first-rate. Having known Fred and David for years, it was a no brainer that I would work with them. Years later, they still strive daily (and we do almost talk daily about our common clients!) to provide me with the best prices, and the amazing personal service that I have always known them for. I look forward to doing more of the same for many years to come.
Rodolphe Mortreuil Office Anyplace
When a very large phone company couldn't supply us with a reliable phone service, we turned to David and Fred, after a recommendation. They have since supplied us with a phone service that not only covers our needs but also provides us with a personal service. They are always available at the end of the phone/email for advice and help and will come in for a site visit if needed. I would recommend them without any hesitation, if you want great customer service with a phone service that matches then they are the people for you.
Miguel Povoas Hurst Farm Dental Practice
OMG, what a breath of fresh air. Finally a company that does what it says it will when it says it will. Faultless and fantastic. Thank you Fred and David.
Jerry Blay Bay Tree Foods
I have been a customer of Fred and David at One Cloud for years and have never received anything other first class service and advice. As a small business owner myself I really appreciate the "personal touch" that they provide. I would thoroughly recommend them.
Lee Amos Tyred & Exhausted
Fred was really patient, listened to our needs and came up with the perfect solution for our company phone system. Moreover, he's always available when we need ! I would highly recommend him and his company !
Eline Engelbracht Best of Tours
Fred, David and the team have delivered. They did what they said and said what they did. Outstanding service and a seamless change over. Dealing with real people who care is a gift, thank you gents - 5 stars from Barkers Motor Works.
Richard Barker Barkers Motor Works
Really great, friendly team, good simple explanations when it comes to what's on offer (super handy if you're starting a new business), and great support should you need it, nothing is too much trouble. Fantastic customer care.
