Onestream sells low-cost home broadband UK-wide from Hampshire, and took over the Cuckoo brand and its customers in May 2026.
About Onestream
Onestream sells home broadband across the UK from a base in Whiteley, near Fareham in Hampshire. The company was set up in 2016, and its home page advertises packages from 40Mbps up to 990Mbps.
In May 2026 Onestream bought the Cuckoo customer base, brand and web address from AllPoints Fibre Networks, which now sells only to other providers. That leaves Onestream running 2 home broadband brands, and Cuckoo's own site now says it is part of the Onestream family.
If you are with Cuckoo, its update page says your package, price and network stay as they were, and your line still runs on AllPoints Fibre's wholesale platform. Onestream customers can check availability and packages with a postcode search on its site.
