Zen Internet added thousands of broadband connections during its latest financial year, with Full Fibre driving much of the growth. The company’s home broadband customer base increased by 15%, despite Zen rarely being the cheapest option available at an address.
One figure needs explaining. Zen finished the year with 225,000 broadband circuits, up from 208,000. That total includes connections supplied through its consumer, business and wholesale partner divisions, so it should not be presented as 225,000 home broadband subscribers.
The accounts point instead to Full Fibre and Zen’s partnership with CityFibre as the main reasons for its consumer growth. Zen also sells services over Openreach, giving it broader availability than providers tied to a single smaller fibre network.

Zen is selling certainty rather than cheap broadband
Zen’s clearest difference is its Contract Price Promise. The monthly broadband price remains fixed throughout the minimum contract, while many larger providers write an annual increase into their deals. Zen admits that absorbing supplier cost increases reduced its profit margin, which shows the promise has involved more than a line of advertising.
There is also independent evidence that people like the service they receive. Zen topped the 2026 Which? broadband survey with a customer score of 84%, ahead of every other provider included. Its packages also come with UK support and a static IP address, while speeds reach 2Gbps in some areas.
There are compromises. Zen often costs more than budget rivals, whole-home Wi-Fi can add to the monthly bill and prices may change after the minimum contract ends. Its reported £3.1 million operating profit also included £4.8 million from selling internet addresses, so the increase was not simply generated by charging households for broadband.
