Staying informed when the internet is down

Updated October 2026

When the internet goes down, you still want to know what is happening. Here is how, without relying on Wi-Fi.

Emergency Alerts

Emergency Alerts are a free UK Government service that warns you of a danger to life nearby, such as severe flooding. They arrive on compatible 4G and 5G phones and tablets, with a loud siren-like sound even if your phone is on silent.

• You do not need to sign up or install an app.
• They do not need your phone number or track your location.
• You will not receive them if your phone is off or in aeroplane mode.
• To check an alert is genuine, go to gov.uk/alerts.

We suggest leaving them switched on. You can see or change the setting by searching your phone's settings for "emergency alerts".

A battery or wind-up radio

If the internet goes down, a radio still works. Local and national stations broadcast updates during emergencies. Keep spare batteries with it, or choose a wind-up model.

Your phone

• Keep a charged power bank, and keep your phone above half charge when bad weather is forecast.
• Broadband and cordless landline phones usually stop in a power cut. A corded landline phone may still work.
• Mobile networks can be strained in an emergency. Text messages often get through when calls do not.
• In a life-threatening emergency, try 999 from a mobile if your landline is not working.

Make a simple plan

• Write down three important phone numbers on paper.
• Agree who everyone will contact if you are separated, ideally someone outside your area.
• Save 105, the free number to report a power cut.

Weather warnings

Check the Met Office for weather warnings when storms are forecast, so you can charge things and fill a flask before the power goes.

Where this advice comes from

Based on the UK Government's Emergency Alerts information and the UK Government Prepare website. This guide is general advice for ordinary households, not a substitute for official guidance. In an emergency, call 999.
