Home Broadband ISP Cuckoo Sells UK Customer Base to Onestream UPDATE

Monday, May 11th, 2026 (2:00 pm) - Score 5,160
Cuckoo-Logo-Yellow-Stacked-2023

Retail internet service provider Cuckoo, which is the consumer broadband outlet for the associated AllPoints Fibre (APFN / Fern Trading) network and wholesale platform (they also provide services via several third-party full fibre networks, such as Openreach and CityFibre), has confirmed to ISPreview that rival ISP Onestream will acquire their customer base.

The agreement, which is perhaps not surprising given last year’s report of redundancies at Cuckoo (here) and the wider market strains that operators are continuing to feel (both economically and competitively), will see Cuckoo’s customer contracts, brand, and domain all transfer to Onestream, although all customer connections are to remain on APFN’s wholesale aquila platform.

Onestream is already said to have completed full API integration into aquila in just eight weeks, “enabling rapid onboarding and future scalability“. Onestream will also gain access to a broader full-fibre portfolio – including Openreach, CityFibre and APFN’s own assets. Onestream said they expect to benefit from continued development of aquila to enable access to more capabilities and services over time.

The flip side of this move is that it could also be seen as freeing up APFN and aquila to be more of a wholesale-only network, which removes the inevitable conflict of interest that emerges within more vertically integrated operators and could improve their competitive flexibility. But it’s worth noting that they do still control one other retail ISP – Brillband, at least for now.

Nisreen El-kaloush, Chief Commercial Officer at APFN, said:

“APFN was built to give the channel a simple, more modern route to market. aquila brings this to life by unifying leading fibre and Ethernet networks into a simple marketplace that includes automation, service visibility and API-driven workflows. This long-term partnership gives Onestream full access to everything aquila has to offer. We are excited to enter this new chapter together – creating a more streamlined, scalable experience for ISPs, MSPs, resellers and wholesalers across the UK.”

Sarah Hill, Managing Director at Cuckoo, said:

“I am enormously proud of the Cuckoo team and the business we have built together; an enviable culture underpinned by a commitment to deliver outstanding customer experiences. The team will begin planning a seamless transition to Onestream, where I know our customers will be in good hands.”

Steve Evans, Managing Director of Onestream, said:

“We are delighted to welcome Cuckoo customers to Onestream. This strategic move significantly expands our customer base, giving them access to full-fibre and high-speed broadband across the UK, our competitive pricing, and our commitment to excellence in customer service and support.”

ISPreview understands that the announcement was made at an all-hands meeting earlier today and, perhaps due to this, there’s currently not a lot of customer-facing information being provided. But our sources tell us that Cuckoo could close as soon as the end of this month. Equally, it seems likely that there may now be more redundancies, although this has yet to be confirmed.

Such deals would normally be accompanied by detailed customer information or FAQs on timescales, pricing commitments and contract changes (where applicable), but at present the above is all we have. Naturally some of Cuckoo’s customers will not be happy with this and may wish to switch to a different provider, thus we’re currently awaiting some clarification on how they’ll handle this.

One other big question mark is whether this agreement will enable Onestream to finally start selling access to APFN’s own consolidated full fibre broadband network (covering the former networks of Jurassic Fibre, Swish Fibre and Giganet), which for a long time has stopped being available to new customers via Cuckoo. The timing of today’s announcement does roughly align with our previous report on this (here).

UPDATE 2:51pm

Onestream has issued a press release of its own, which confirms that the agreement will result in the ISP “doubling” their customer base to 150,000 (this suggests that somewhere around 75,000 customers are being moved).

In addition, APFN and Cuckoo have also responded to some of our questions:

  1. Will Cuckoo allow customers, such as those already out of contract, to switch to a different ISP if they don’t want Onestream?

“We will be transferring customer contracts to Onestream based on their current service, terms and conditions and price, as set out in their contract, so the early termination and cancellation provisions will continue to apply.” – Cuckoo spokesperson

  1. How many redundancies, if any, are expected from the Cuckoo side?

“All roles within Cuckoo will be placed at risk of redundancy and we are entering into a period of collective consultation. Naturally, this is a difficult time for the team, and our priority is to make sure everyone feels supported throughout the process.

I would personally like to thank every individual affected by today’s news for their hard work and dedication to the Cuckoo business.” – Sarah Hill, Managing Director, Cuckoo

  1. What is the timescale for the customer migration?

“We are dedicated to ensuring a smooth transition period for customers. Timescales are being finalised, and customer communications are now being issued as part of a structured transition plan.” – Cuckoo spokesperson 

  1. Are there any customer FAQ/information pages available on the deal?

“Customer FAQs will be made available online once the migration timelines are finalised. We will be in touch.” – Cuckoo spokesperson

  1. So far, Cuckoo has not been able to allow new customers to sign-up to use APFN’s own-built consolidated fibre network (formerly Jurassic Fibre, Swish Fibre and Giganet). Will Onstream be able to take orders for customers wanting to join that network?

“APFN is finalising a unified footprint for the former Swish Fibre, Jurassic Fibre and Giganet networks. It will be published on the Aquila platform to give partners clear visibility of all serviceable premises. We will share an update once this exciting step goes live, alongside ongoing platform improvements.” – APFN spokesperson

    Is this a grand plan to split up all the brands again so they can pointlessly bring them back together?

    The absolute shambles never ends.

    Jurassic Failure was a joke the entire time they existed, then binned off into this Allpoints thing with the cuckoo thing where they don’t even sell on-net service anyhow where they had actually gotten around to deploying their own fibre…

    …and now they’re shuffling the cuckoo stuff off too.

    It’s almost like this entire investment was a dud to begin with…

    I was just looking at them – I am glad I didn’t go through with it – onestream are a nightmare I am told

    As a past employee this makes me really sad – more redundancies yet again, peoples lives messed about with because a select group of people can not work out strategy and constantly move on to the next big idea/thing. I really hope this is handled well for those will be departing, to add to the many cast out before over time.
    At what stage will the investors realise what a truly awful company this really is – led by some who clearly can not manage anything properly. How long will this carry on?!
    If still there would suggest run don’t walk..

      Don’t feel too sorry for the investors. They’re all participants in an Inheritance Tax avoidance scheme, available only via IFAs.

      A small amount of due diligence by anyone offered it by their IFA would renewal that it’s rate of return has been consistently below 3%, so you’d be throwing away potentially huge amounts of money in reduced returns, just to keep it away from the taxman.

      Plus, a scheme’s validity under BPR isn’t confirmed until you actually claim on it – i.e. after you’re dead – so although the risk of it turning out to be non-compliant is low, it is there.

    Someone on the previous article in July predicted they’d be selling off their customer base within 6 months.

    They weren’t too far off.

    Sounds interesting…

    > Onestream will also gain access to a broader full-fibre portfolio – including Openreach, CityFibre and APFN’s own assets

    Does this _finally_ mean that APFN’s own networks will accept new customers again?

      Would you want to be relying on it???

    2. Avatar photo Ben says:

      I’d be happy to use an APFN-based ISP as one of my internet connections, at the right price. I currently have two independent fibre connections and a 4G-based connection for resiliency – IMO if a reliable internet connection is important then it would be foolish to only have one.

    Is this the second time since 2022?

      I believe you may be thinking of the time they gave Openreach customers the boot: https://www.ispreview.co.uk/index.php/2024/02/shock-as-uk-broadband-isp-cuckoo-gives-some-customers-the-boot.html

    Fern invested over a billion quid in how many companies, smashed them all together and now, at the end, sold just 75k customers.

    What an utterly devistating outcome for them – but obvious for anyone with eyes.

      Customer Aqc cost of £13,333.33, and an average spend per customer of what? £400 a year? Total disaster!

    Based on the haplass retail side of things, who the hell in their right mind would choose to use them for wholesale. This company is run and managed by complete and utter clowns

  11. Avatar photo Bob says:

    Cuckoo in the published accounts made a large lose yet managed to pay one director £560K . The parent company also appeared to make a loss

  12. Avatar photo Big Dave says:

    See the website is now closed to signing up new customers this morning.

    Everyone is still talking about how tragic Octopus and Fern is performing for their Inheritance Tax avoiding investors.. Let alone their Allpoints Fibre AltNet that turned off their networks in front of the whole industry and the became an aggregator? But, what about the customer experience and endless churn?? Where is the Telecom’s regulator in all of this, hang your head in shame Ofcom!!

    1. Avatar photo MikeP says:

      Difficult to see how much of this s**tshow falls under Ofcom’s remit. It certainly isn’t to prevent commercial operations making batty business decisions. I don’t think anyone expects a regulator to second guess those!! If they did, the Nanny State would definitely be here.
      As long as service continues, shouldn’t be an issue for customers, at least until renewal comes along. Now, if APFN starts turning off their existing networks, that would be a different matter. I think we all know how much maintaining them without being able to onboard new customers is likely to be costing them.

    I used to work at Cuckoo. As soon as I joined it was clear that they were never going to turn a profit. It’s a tough market but the leadership team are inexperienced. The CEO who was sacked acted more like an advisor than a CEO. I’ve never seen anyone less involved in the running of a business.
