Three broadband problems?

Three is working fine, checked at 06:40 on 28 October 2026. Last report 23 h 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. Three status

The Three troubleshooter, explained

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

Three sells 2 speeds of 4G and 5G home broadband today, from 10 Mbps to 150 Mbps. The speed depends on the signal where your router sits.

Three home broadband runs on Three's own 4G and 5G mobile network, so there's no line for an engineer to fix. If it's slow or keeps dropping, the signal and where the router sits are the first things to check.

This is 4G or 5G home broadband, so the signal is everything. Move the router next to a window, as high up as you can.

Switch it off at the wall for 30 seconds and back on, then test close to it.

If speed drops at busy times of day, that's the mobile network near you rather than a fault in your home.

Call Three on 0333 338 1001 (Mon to Fri 8am to 8pm, Sat and Sun 9am to 6pm) to report a fault. Or 333 from a Three phone.

Three 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 Three first. If it isn't sorted after six weeks, you can take it to the free dispute scheme Three belongs to.

Three 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 Three's outage picture, the speed tests other Three 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 Three, 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: Three's outage picture on our status page (its own status where it publishes one, plus what people are reporting), the speed tests other Three 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.
