Next update: when Cuckoo or Onestream change Cuckoo’s plans or prices, or at the start of December 2026.
By: Switch Editorial Team, Switch Squid Ltd
As of 24 October 2026, Cuckoo is a full fibre broadband brand now run by Onestream, with three full fibre speeds (150Mbps, 500Mbps and 900Mbps), £0 set-up and a Cuckoo Hub with Wi-Fi 6 mesh included; prices depend on your address, and Cuckoo shows them once you enter your postcode. Its Trustpilot score is high, at 4.6 out of 5 from over 11,000 reviews, but most of those reviews were written before Onestream took over in May 2026, so the service you sign up to today is not quite the one most reviewers describe. This SwitchSquid review explains who owns Cuckoo, which networks it uses, what it costs and how it compares with BT and Hey!Broadband. We don’t have a commission link for Cuckoo, so the buttons on this page go to BT and Hey!Broadband. We may earn a commission if you buy through those links; it doesn’t change the price you pay.

BT Full Fibre 150: £23.99 a month, with help on leaving fees
- Full Fibre 150 at £23.99 a month on 24 months on the offer page our link opens, when we checked on 23 October 2026
- Up to £300 towards leaving fees, paid as bill credit
- Main limitation: the price rises to £27.99 in March 2027 and again in March 2028, and BT Full Fibre must reach your address
Is Cuckoo broadband any good? The short verdict
Cuckoo built a strong reputation for friendly support and simple full fibre deals, and its Trustpilot rating is still one of the highest of any UK broadband brand. The question in late 2026 is whether that carries on under new ownership. Cuckoo’s customer base, brand and website moved to Onestream in May 2026, and Cuckoo is now taking new orders again through a new postcode checker on its website.
Cuckoo’s prices depend on your address, so compare its price for your postcode with BT Full Fibre 150 at £23.99 a month on the offer page our link opens, and Hey!Broadband’s 150Mbps plan at £23 where Hey is available. Cuckoo’s strengths are £0 set-up, a mesh Wi-Fi hub included as standard, and a simple choice of three speeds.
Our advice: check Cuckoo at your address, then compare the same speed with at least two other providers before you commit to 24 months.
Who owns Cuckoo Broadband?
Cuckoo is now part of the Onestream group. Cuckoo’s website says “Cuckoo Broadband is part of the Onestream family”, with its registered office at Onestream’s base in Whiteley, Hampshire, when we checked on 23 October 2026.
Until May 2026, Cuckoo was the consumer brand linked to AllPoints Fibre Networks (APFN), owned by the investment group Fern Trading. On 11 May 2026, Cuckoo confirmed that Onestream would take over its customer contracts, brand and domain, and paused new sales from 4pm that day, as reported by ISPreview and Choose. Onestream said the deal would roughly double its customer base to about 150,000. Cuckoo’s own update page tells existing customers that their contract, speed and price stay the same, with billing and account management moving to Onestream.
Onestream itself is a Hampshire-based provider owned by Ridown Capital, according to Companies House. It doesn’t yet have the Trustpilot history Cuckoo built up, so how it runs Cuckoo over the next year matters.
Which network does Cuckoo Broadband use?
Cuckoo sells full fibre only. Its connections run through APFN’s Aquila wholesale platform, which gives access to Openreach, CityFibre and APFN’s own fibre network, according to Choose and ISPreview. Cuckoo says prices and upload speeds depend on which network reaches your street, so it shows them only after you enter your postcode.
Upload speed matters for video calls, cloud backups and sending large files; our guide to broadband upload speeds explains how much you need. If your address is on a different network, your speeds and price may differ.
Cuckoo prices in October 2026
Cuckoo sells three full fibre speeds, all with a Cuckoo Hub (Wi-Fi 6 mesh) and £0 set-up, according to its broadband page, checked on 24 October 2026. Prices and upload speeds depend on which network reaches your street, so Cuckoo shows them once you enter your postcode, with no obligation and no card details.
Cuckoo plan | Download speed | Monthly price | Set-up | Hub |
|---|---|---|---|---|
Full Fibre 150 | 150Mbps | Depends on your address | £0 | Included |
Full Fibre 500 | 500Mbps | Depends on your address | £0 | Included |
Full Fibre 900 | 900Mbps | Depends on your address | £0 | Included |
Check the order summary and contract summary for your address before you pay, including any April price rise, because those are what you are agreeing to.
Cuckoo vs other full fibre providers
Here is how Cuckoo compares with two providers we can link to, on prices we checked on 23 October 2026.
Cuckoo (Onestream) | BT Full Fibre | Hey!Broadband | |
|---|---|---|---|
Entry full fibre plan | Full Fibre 150, price depends on your address | Full Fibre 150, £23.99 a month (24 months), £27.99 from March 2027 | Superfast 150, £23 a month (24 months), rising £2 each April |
900Mbps plan | Full Fibre 900, price depends on your address | £33.99 a month on bt.com | Available in Hey’s areas |
Set-up | £0 | £0 activation on Full Fibre 900 at bt.com | Shown at checkout |
Switching help | One Touch Switch | Up to £300 towards leaving fees, as bill credit | £100 bill credit with One Touch Switch (24-month plans) |
Where available | Openreach, CityFibre and APFN areas | Wherever BT Full Fibre reaches | Parts of London and the South |
Our view: Cuckoo’s price depends on your address, and the included mesh hub and £0 set-up count in its favour. If BT Full Fibre or Hey reaches your address, compare the 24-month total, not just the first month. For more full fibre options, see our Hyperoptic review, YouFibre review and Hey!Broadband review.
Choose Hey!Broadband Superfast 150 for £23, with £100 credit when you switch
- 150Mbps download and upload for £23 a month on a 24-month plan
- £100 bill credit when you use One Touch Switch (24-month plans only)
- Only in parts of London and the South, and the price rises by £2 each April
What do Cuckoo customers say?
On Trustpilot, Cuckoo had a TrustScore of 4.6 out of 5 from over 11,000 reviews when we checked on 24 October 2026. Trustpilot’s summary of recent reviews says customers often praise friendly, helpful support staff and a smooth switching process. Trustpilot doesn’t fact-check reviews, and most were written before Onestream took over.
There have been bumps since the move. In September 2026, ISPreview reported that some former Cuckoo customers who had a static IP address were moved onto shared (CGNAT) connections. Onestream said 88 customers were affected and that it expected to restore their normal service soon. If you need a static IP for home servers, remote access or security cameras, ask Onestream directly before ordering.
Threads on MoneySavingExpert’s forum (July 2025) and Reddit describe individual customers’ experiences, all from before the change of ownership.
Which broadband provider has the best reviews in the UK?
In Which?’s January 2026 broadband customer survey, Zen Internet came top with a customer score of 84%, followed by Hyperoptic (77%), Community Fibre (72%) and Plusnet (71%). Among the big names, BT scored 65%, Sky 62%, and TalkTalk and Virgin Media 59%, with Now Broadband last on 54%. Cuckoo didn’t appear in the table, because Which? only lists providers with enough responses. (Which?, January 2026 survey)
Which broadband providers are most complained about in the UK?
Ofcom’s latest complaints figures, for January to March 2026 and updated on 30 July 2026, show TalkTalk as the most complained-about fixed broadband provider, with 10 complaints per 100,000 customers. Vodafone had 8 and BT 7, while EE and Virgin Media matched the industry average of 6. Plusnet had the fewest at 4, with Sky on 5. Ofcom only reports on the largest providers, so smaller ones such as Cuckoo and Onestream aren’t included. (Ofcom; figures as reported by Uswitch, 3 August 2026)

Who it suits
Good fit: you want simple full fibre with a mesh hub included and £0 set-up, and Cuckoo’s price at your address is close to the alternatives.

Know before you buy: Cuckoo is now run by Onestream, and prices rise each April.
Important conditions
Cuckoo’s prices and upload speeds depend on the network at your address; check the order and contract summary before you pay.

Our verdict
Cuckoo, October 2026: a well-reviewed full fibre brand now run by Onestream, with three speeds, a mesh hub and £0 set-up. Prices depend on your address, so check yours on Cuckoo’s website (checked on 24 October 2026). Main limitation: you can’t compare its price until you enter your postcode, and most of its glowing reviews pre-date the change of ownership, so compare BT and Hey at your address first.
