About Us

Ultrafast & superfast broadband providers in Kent, East Sussex, Hampshire and Berkshire

  • We are dedicated to building pure fibre to the premises (FTTP) networks for ultrafast broadband speeds up to 1 Gigabit per second

  • Our support teams are friendly, local and passionate about connecting everyone to the broadband speeds they deserve

A quick look back

Call Flow was established in 2002 by Andrew Conibere, an engineer who had accumulated the knowledge and skills to build telecommunications network infrastructure in areas that were not receiving sufficient investment from the major telecommunications operators.

He believed that everyone should have access to the new broadband technologies, and was passionate about using his expertise to invest in areas that were getting left behind. Call Flow’s first networks were all in Kent and we now successfully serve parts of East Sussex, Hampshire and Berkshire, with many more locations planned.

Forward thinking

As the years have passed, Call Flow has adapted to provide services that meet the growing demand for superfast and now ultrafast broadband. We’ve become one of the largest UK providers of what is called ‘Sub Loop Unbundling’. This is where we build our own street cabinets and network to provide superfast Fibre to the Cabinet (FTTC) services where BT has decided not to invest in this technology (so the BT Infinity services are not available). 


In 2017, we started the first of many exciting ultrafast fibre deployments. Our ultrafast fibre is a brand new network that uses only fibre optic cables, not the old copper lines. These networks are delivering speeds of up to 1 Gigabit/s to each customer, and in the years to come can support even higher speeds if needed. 

Proud to be local

Our head office is still situated at the heart of our network in Kent, where the adventure began. We aim to provide the highest level of service and customer care and believe our local workforce, with its local knowledge, makes a positive difference.

We work closely with the communities that are already covered by our networks, as well as with those that are seeking to benefit from our state-of-the-art infrastructure in the future.

Call Flow’s unique approach to rapid fibre network deployment

There is no such thing as a ‘typical’ rural or other underserved area. It’s why we combine our wide-ranging technical and practical capabilities to offer solutions for ultrafast and superfast broadband in the hardest-to-reach areas.
