About Cuckoo
Cuckoo launched in 2020 with a clean, single-tariff, no-contract pitch targeting consumers who were tired of price-rise renewal cycles from incumbents. The brand has grown quickly through word-of-mouth, strong Trustpilot ratings, and a marketing tone that emphasises transparency and simplicity over speeds-and-feeds. Cuckoo retails Openreach FTTC and FTTP and has selectively added altnet wholesale where it expands the addressable footprint at competitive cost. For switchers, Cuckoo is the natural pick for households who want a flexible monthly bill, no upfront fees, and a brand that genuinely tries to keep things simple.
