How to contact Cuckoo customer services and technical support

How to contact Cuckoo support and customer service

Existing Cuckoo customers signed up on or after 13 February 2024

If you signed up before 13 February 2024, your package will no longer be with Cuckoo. For further help, you’ll need to get in touch with Home Telecom.

Cuckoo Internet Live Chat

You can access Cuckoo’s Chatbot through any back on the broadband provider’s website. Look out for the ‘magnifying glass’ icon in the bottom right-hand corner of any page.

You might also find answers to questions in the Cuckoo Help Centre.

How to check Cuckoo’s service status - is Cuckoo broadband down?

Cuckoo doesn’t currently offer a status checker tool, and it’s not a provider that’s covered by DownDetector, so you may find it useful to check social media for any recent queries from other customers. You’ll find Cuckoo on Twitter / X at x.com/CuckooInternet.

If not, get in touch with Cuckoo using the details above.

Complaining about Cuckoo to the ombudsman

All internet service providers must belong to one of two ADR (Alternative Dispute Resolution) schemes to resolve problems if you cannot reach an agreement.

For Cuckoo, contact Communications Ombudsman

Phone: 0330 440 1614

Email: [email protected]

Full address: Communications Ombudsman, PO Box 730, Warrington, WA4 6WU.

However, there are steps you must take before contacting the ombudsman. To use an ADR, you must first receive a deadlock letter from the provider. You can also go to the ombudsman if a provider does not respond to your complaint within eight weeks.

Our guide to complaining about broadband explains this in more detail, so head over there for more help if you feel you might need to go this route.

Can’t get Cuckoo at your new address? Switch and save money

If you’re moving home, you may find you can’t get Cuckoo broadband at your new address. Cuckoo now solely only offers full fibre broadband (FTTP) deals on the CityFibre network. Of course, you can use Broadband Genie’s deals checker to try your new postcode and check availability, or to look for alternative providers to switch to.

If Cuckoo deals don't show up, we recommend getting in touch with the Customer Service department as soon as you can.

Unfortunately, cancelling a contract early will result in early termination fees being charged.
