Can you still sign up to Cuckoo broadband?
No. Cuckoo broadband stopped accepting new customers on 11 May 2026, and its customer base was sold to Onestream. Orders placed after that cut-off were cancelled rather than transferred. If you have landed here looking to switch to Cuckoo, that option has gone.
This is worth saying plainly, because plenty of comparison pages and review sites still list Cuckoo broadband deals with prices attached. Those listings are stale. The provider is not taking sign-ups, and a price you cannot actually buy is not a price.
If you are already a Cuckoo customer, nothing about your service stopped working. The rest of this guide is about what the move actually means for you, and where your rights sit.
What happens to your Cuckoo broadband service now?
Existing customers keep their service running through the migration to Onestream. Your contract terms and the price you agreed carry over initially rather than changing on the day of the transfer, and your connection is not meant to be interrupted by the handover itself.
Cuckoo ran on the Openreach network, the same physical lines BT, Sky and Plusnet sell over. That does not change with the owner. The cable in the street is the same one it was before, so the move is a billing and customer-service change rather than an engineering one.
When your current contract reaches its end, you renew as an Onestream customer on Onestream’s terms, not on the deal you originally signed with Cuckoo. That is the moment worth putting in your calendar.
Key takeaways
- Cuckoo stopped taking new customers on 11 May 2026; the customer base went to Onestream.
- Existing service continues, and your agreed contract terms and price carry over at first.
- Out of contract? You can switch away at any time with nothing to pay.
- Still in contract? A materially detrimental change to your terms triggers a penalty-free exit under Ofcom rules.
- Cuckoo ran on Openreach, so switching to another Openreach provider is a like-for-like move on the same line.
Can you leave without paying an exit fee?
It depends where you are in your contract. If your minimum term has already ended, you are free to switch whenever you like with no exit fee, which is true of any provider and is the simplest position to be in.
If you are still inside your minimum term, the default is that your existing terms continue to bind you. The exception matters though: under Ofcom’s rules, if a provider makes a change to your contract that is materially detrimental to you, such as a price increase you did not agree to when you signed, you get a window to leave penalty-free. Watch for any notice of changed terms landing in your inbox, and read it rather than filing it.
Our guide to broadband exit fees covers how those charges are calculated if you do decide to go early, and broadband mid-contract price rises explains the rules on what a provider can and cannot change midway through.
What did Cuckoo actually offer, and does it still exist elsewhere?
Cuckoo built its reputation on two things: flexible contract terms, including genuine rolling monthly options at a time when most of the market insisted on 12 or 18 months, and customer service that consistently rated well. Its Trustpilot score sits at 4.6 out of 5 from more than 10,000 reviews, which is above where several much larger providers land.
Those are the things worth carrying into your next decision rather than mourning. If flexibility was why you chose Cuckoo, look for rolling or short-term contracts when you compare, particularly if you rent or move often. If service quality was the draw, check independent review scores and Ofcom’s published complaints data rather than the size of the brand name.
What you should not do is assume the new arrangement automatically matches the old one. It might suit you perfectly well, but it is a different company with its own pricing and its own terms, and it is worth actively checking rather than drifting.
What to do next if you were a Cuckoo customer
Find out when your minimum term ends, because that single date decides whether you are free to move now or waiting for a window. Check any correspondence about changes to your terms, since that is what opens a penalty-free exit if you are still locked in.
Then compare what is actually available at your address before your contract rolls over, rather than after. Cuckoo ran on Openreach, so any other Openreach provider is a straightforward switch on the same line, and under Ofcom’s one touch switch rules your new provider handles the whole thing, including telling the old one. You do not need to ring anybody to cancel.
