We’re a UK carrier that owns a voice, data and mobile network, giving us more control over the services we offer.

We only provide services for the business market and place huge emphasis on the availability, reliability and quality of the network and platforms that underpin our products. Our network architecture has been built without the hindrance of legacy platforms, enabling simplicity in service delivery and very high levels of automation for service provisioning and support. This is complemented by a comprehensive governance structure that assures the security of our platforms and business continuity of our support services. As such, the majority of our products are accredited to ISO 9001, ISO 27001, ISO 22301 and ISO 14001.

Investing for the future

We continue to invest for the future, ensuring the continued evolution of our network for unified communications and beyond, providing both converged services and discrete voice, data and mobile components.

Our network has been designed and deployed to:

  • Ensure very high levels of system availability through multiple layers of technical and geographical resilience
  • Support all the network elements of a converged solution, provided as an integrated solution or as component parts
  • Support the end-to-end automation of customer transactions between our portal and network platforms enabling customers to place orders, configure services and access a range of product functions, as well as providing a suite of tools to manage billing and usage
