Cuckoo broadband problems?

Cuckoo is working fine, checked at 06:40 on 28 October 2026. Last report 19 d ago, nothing since. If yours still feels off, it's more likely your WiFi or kit than the line. A speed test will tell you. Cuckoo status

Start the troubleshooter

Reads live UK outage data · updated every few minutes

We'll check Cuckoo's status, probe your line and walk you through the fix. Then we'll show you what to switch to if it's not worth waiting.

How it works
  1. 01
    What's wrong?
    Pick the shape of the issue: no internet, slow, Wi-Fi only or keeps dropping.
  2. 02
    Silent probe
    We check Cuckoo's outage status, speed tests from other Cuckoo customers near you and your own recent results, all at once.
  3. 03
    One fix at a time
    Each step gets a 'did that help?' button. Try one thing, tell us, move on.
  4. 04
    Escalate if needed
    If two fixes don't work, you get a call script and a comparison of better deals at your address.
What we don’t do
  • Make you read an article and figure it out
  • Push a switch when the fix is a router restart

Cuckoo guide

The Cuckoo troubleshooter, explained

1 day with an incident in the last 30 days. If it's happening right now, check our Cuckoo status page first. If Cuckoo is down for lots of people, no fix at your end will help, and the page shows when people stop reporting problems.

Cuckoo sells over CityFibre and Openreach, depending on the address. Who sends an engineer depends on which network reaches your home, and Cuckoo books them either way.

Call Cuckoo on 0330 912 9955 (Mon to Fri 9am to 7.30pm, Sat and Sun 9am to 4pm) to report a fault. Sundays: technical help only.

Cuckoo hasn't signed Ofcom's voluntary broadband speed code, so there's no set 30-day right to leave over slow speeds. Report it to Cuckoo first. If it isn't sorted after six weeks, you can take it to the free dispute scheme Cuckoo belongs to.

Cuckoo isn't signed up to Ofcom's automatic compensation scheme, so there's no automatic payment while it's down. Ask for a credit for the days you were without it. How automatic compensation works

Five short questions, one at a time. Then we check Cuckoo's outage picture, the speed tests other Cuckoo customers near you ran in the last 24 hours and any recent test from your postcode, and suggest one fix at a time with a "did that help?" button.

If two fixes don't work, you get a script to read out when you call Cuckoo, filled in with how long it's been going on and what you've tried, next to the cheapest deals at your address from other providers in case you'd rather leave. We earn a commission if you switch through us, never if you stay.

Three things at once: Cuckoo's outage picture on our status page (its own status where it publishes one, plus what people are reporting), the speed tests other Cuckoo customers in your postcode district ran in the last 24 hours and any test from your postcode in the last hour. That tells us whether it looks like a wider problem or something at your end.

Outages, the speed tests we compare against and the deals we'd suggest all depend on where you are. A postcode lets us tell a problem in your area from one on your line.
