The connectionyour business runs on
Reliable connectivity for businesses that depend on the internet — symmetric speeds, real SLAs, a Cambridge-based engineer when you need one, and the room to grow from broadband through to dark fibre on the same network.
Connectivity you can plan around
Performance your business can depend on
Modern businesses run on the connection. Cloud apps, video calls, hosted phones, backups, payments — when the line wobbles, work stops. We build our service to the standard that demands.
Symmetric speeds with real upload, dedicated bandwidth that doesn’t shrink at peak times, and a support team based in Cambridge who know what the network looks like before they pick up the phone. When you need more — more capacity, a second site, a redundant route — we move you up without changing supplier.
Our network reaches across Cambridge and the surrounding villages — Histon, Impington, Oakington, Bottisham, Stow-cum-Quy and the Wilbrahams among them — and out to Newmarket and Bury St Edmunds.

Why CFN for business
Three things that matter when the connection is critical
Performance you can guarantee
Symmetric speeds, dedicated bandwidth that does not shrink at peak times, and an SLA that pays out when uptime targets slip. The number on the bill is the speed you get, every minute of every day.
Support that owns the problem
When something goes wrong, you reach a Cambridge-based engineer who can see the same network you are sitting on — not an offshore ticket queue. Named escalation, response times in writing, and the people who fix it know what they are looking at.
Diversity and room to grow
We work well as a primary supplier or as a redundant second carrier alongside your existing one. And when your needs change, we can move you up — broadband to DIA to Ethernet to dark fibre — without changing supplier or rebuilding contracts.
