Cuckoo Broadband Deals (April 2026)

Cuckoo broadband offers Full Fibre packages at 150, 500 and 900Mbps on monthly rolling, 12-month, or 24-month contracts, primarily on the CityFibre network. Prices start from £32/month (24-month) with half-price deals on the first six months. Cuckoo is B Corp certified, fixes prices within the contract term, and includes an eero Pro 6E router worth £250.

Cuckoo Broadband Packages and Prices in April 2026

Cuckoo offers three Full Fibre speed tiers in April 2026. The C-150 (average 150Mbps) is available at £32/month on a 24-month contract, currently half-price for the first six months (approximately £15.50/month for months 1–6). The C-500 (500Mbps) costs £34–35/month on a 24-month plan, and the C-900 (900Mbps) is £35–38/month on a 24-month term. On 12-month contracts, prices are higher: C-150 at £38/month, C-500 at £42/month, C-900 at £47/month. Rolling monthly options are available but cost more. On CityFibre, all packages deliver symmetrical speeds — so 500Mbps means 500Mbps both up and down. On any legacy Openreach connectivity, speeds are asymmetric. Unlike providers such as NOW Broadband, Cuckoo fixes prices within the contract term — a £3/month annual increase applies on 1 April each year but only after contract end.

Cuckoo's B Corp Credentials and Ethical Stance

Cuckoo is one of a small number of UK broadband providers with B Corp certification, alongside Zen Internet. B Corp status requires verified social and environmental standards across governance, workers, community, and environment. Cuckoo claims to be carbon-neutral and plants trees for each customer. It does not offer phone or TV bundles, focusing entirely on broadband. CompareFibre data shows Cuckoo at 86% overall customer satisfaction and just 3 complaints per 100,000 customers — significantly better than the major high-street brands. Hyperoptic and Zen Internet are similarly positioned as premium-service alternatives to the mainstream market. Cuckoo's UK-based support team and transparent pricing policies attract customers who have been frustrated by larger providers' mid-contract rises.

Cuckoo CityFibre Coverage: Where Is It Available?

Cuckoo's primary network is CityFibre, which covered over 4.7 million premises across 95+ UK towns and cities as of early 2026. CityFibre is expanding with a target of 8 million homes. Cuckoo has also historically served some customers on Openreach BT Wholesale. Symmetric speeds on CityFibre are a key selling point: a Cuckoo C-900 customer on CityFibre achieves approximately 900Mbps both upload and download, compared to around 110Mbps upload on an equivalent Openreach FTTP plan. CityFibre uses XGS-PON technology capable of multi-gigabit speeds, providing headroom for future upgrades. Customers outside CityFibre areas should check whether Openreach FTTP is available via Cuckoo's postcode checker at cuckoo.co.

Cuckoo eero Pro 6E Router: What's Included

Every Cuckoo package includes an eero Pro 6E router (retail value approximately £250) and an eero security and privacy subscription (retail value approximately £200/year) at no extra cost. The eero Pro 6E supports Wi-Fi 6E — the latest generation of Wi-Fi, operating on the 6GHz band for faster speeds and lower interference with older devices. The router is also compatible with Amazon Alexa for voice control. Additional eero mesh nodes can be added to extend coverage in larger homes. The bundled security subscription includes ad blocking, content filtering, and network threat detection. This hardware package is significantly more premium than the standard routers provided by mass-market ISPs like BT, Sky, or TalkTalk.

Frequently Asked Questions

Does Cuckoo offer a no-contract broadband deal?

Yes. Cuckoo offers monthly rolling contracts with 30 days' notice to cancel. These cost more per month than the 12-month or 24-month options — for example, C-150 on a rolling contract is approximately £38/month versus £32/month on a 24-month deal. Monthly rolling suits renters or those who need short-term flexibility.

Is Cuckoo broadband fixed price?

Cuckoo fixes prices within the contract term — no mid-contract rises during your 12 or 24-month agreement. A £3/month annual increase applies on 1 April each year, but this is applied at contract renewal, not during the term. For a genuinely fixed two-year price, Cuckoo is one of the strongest options in the UK market.

What network does Cuckoo use?

Cuckoo primarily uses the CityFibre FTTP network, which covers 4.7 million premises across 95+ UK locations. Symmetrical speeds are available on CityFibre. Some Cuckoo customers are served via Openreach, where upload speeds are lower. Use Cuckoo's postcode checker to confirm which network serves your address.
