Every alert worth signing up for, in ten minutes
Free alerts do the watching for you. In ten minutes you can sign up for flood warnings (Environment Agency, SEPA or Natural Resources Wales), Met Office weather warnings and your water and power companies’ updates; Emergency Alerts arrive automatically. Almost three quarters of people, 73%, have not signed up for flood alerts (British Red Cross, February 2026).
Why bother?
Because the warning usually exists; it just is not reaching people. The British Red Cross found that “almost three quarters (73%) of people said they had not signed up to flood alerts”, and that around a third did not feel confident about what to do to prepare themselves or their homes (British Red Cross, 26 February 2026, checked 29 August 2026). The figures come from an Opinium survey of 2,000 UK adults, with fieldwork between 13 and 17 February 2026.
The reasons people gave for not registering are the useful part: 42% felt they were not at risk, 23% did not know the service existed, 21% doubted it was relevant or useful, 7% were unsure how to sign up and 4% did not want to share their contact details. Most of that is fixable by ten minutes on this page.
Every service on this page is free, official and takes a couple of minutes each. Do the lot in one sitting with a cup of tea, then forget about them until the day they earn their keep.

Flood warnings, nation by nation
England
The Environment Agency’s service sends flood warnings by “a call, text or email”, around the clock, and “the service is free” (GOV.UK, checked 29 August 2026). It covers flooding from rivers, the sea or groundwater, depending on your area. Sign up at gov.uk/sign-up-for-flood-warnings, or by phone on Floodline 0345 988 1188 (textphone 0345 602 6340).
One honest gap: “you cannot get flood warnings for surface water flooding (sometimes known as ‘flash flooding’)” (GOV.UK). Heavy-rain flooding on streets and gardens is exactly what the Met Office warnings below are for.
Scotland
SEPA runs Floodline Scotland. If you are in an area SEPA monitors closely you get a “targeted Flood Warning message for your local area”; otherwise you get “a more general Flood Alert message for the wider geographical area” (myfloodline.sepa.scot, checked 29 August 2026). Register online with an email address, or call Floodline 0345 988 1188 and choose option 2.
Wales
Natural Resources Wales sends warnings “by text message, phone call and/or email” as soon as they are issued for your chosen location, free, and the service covers around 90% of properties at risk of flooding from rivers or the sea in Wales (Natural Resources Wales, checked 29 August 2026). You will need the address you are registering, a phone number that reaches you day or night, and an email address.
Northern Ireland
nidirect points you to maps rather than a warning sign-up: DfI Rivers publishes Flood Maps NI, which “give information on areas that are prone to flooding in Northern Ireland” and let you see an area’s flood history (nidirect.gov.uk, checked 29 August 2026). We found no equivalent sign-up alert service listed for Northern Ireland. Check your address once, and lean on the Met Office warnings and Emergency Alerts for live danger.
Met Office weather warnings
Warnings come in three colours, for eight weather types: rain, thunderstorms, wind, snow, lightning, ice, extreme heat and fog, up to seven days ahead (Met Office, checked 29 August 2026).
- Yellow: issued for a range of situations, often “when it is likely that the weather will cause some low level impacts”.
- Amber: “an increased likelihood of impacts from severe weather, which could potentially disrupt your plans”.
- Red: “dangerous weather is expected”, and you should take action to keep yourself and others safe.
You can get them through the Met Office app, website, email alerts, social media, TV and radio. The app with notifications switched on is the version that finds you in bed; what to do when a warning lands is covered in storms and floods.
Emergency Alerts: the one you never sign up for
Emergency Alerts is “a UK government system that provides warning and advice in a life threatening emergency” (gov.uk/alerts, checked 29 August 2026). When one is issued near you, your phone may “make a loud siren-like sound, even if it’s set on silent”, vibrate and read the alert out, for about ten seconds.
Three things worth knowing. Alerts are sent only by the emergency services and public bodies that deal with emergencies, for things like severe flooding, wildfires and extreme storms. They reach compatible phones based on your current location, and “the government does not need to know your phone number or location to send you an alert”. There is nothing to register: if your phone is compatible and switched on, it is already covered.
Power and water updates
105 is the free number to report a power cut and get information in England, Scotland and Wales; in Northern Ireland it is 03457 643643. Put both in your phone and on the paper list on the fridge, because they are easiest to find before the lights go out.
Your electricity network operator’s own website carries live power cut information during an incident, and several let you register for updates in advance. National Grid Electricity Distribution, for example, offers storm updates you can choose to receive “before, during and after severe weather incidents that are likely to impact the electricity network”, covering the weather, the areas affected and how many customers are off supply (National Grid, checked 29 August 2026). Operators differ, so check the one that covers your postcode.
Water companies post incident updates on their websites and apps, which is how you find bottled water stations when the water goes off. For advance, personal contact rather than public updates, the Priority Services Register is the stronger tool: free extra support from energy and water companies if anyone in your home needs it.
Frequently asked questions
Are flood alerts free?
Yes. The Environment Agency states plainly that “the service is free” (GOV.UK, checked 29 August 2026), and the SEPA and Natural Resources Wales services are also free to join. Nobody official will ever charge you to be warned.
Do flood warnings cover surface water flooding?
No. GOV.UK is explicit: “you cannot get flood warnings for surface water flooding (sometimes known as ‘flash flooding’)”. For sudden heavy-rain flooding, Met Office rain and thunderstorm warnings are the relevant alert, so have both.
Do I need to sign up for Emergency Alerts?
No. The system needs no registration and no app: alerts reach compatible phones near the emergency automatically, based on current location, and the government does not need your phone number to send one (gov.uk/alerts, checked 29 August 2026).
What if I don’t have a smartphone?
You are still covered. Flood warnings arrive as a phone call to a landline if you choose, signed up via Floodline 0345 988 1188. Weather warnings run on TV and radio, and 105 works from any phone.
Can I sign up for a relative’s address?
Yes. The Welsh service, for example, asks for “the address or location you are registering for” plus your own contact details, and the English and Scottish services work the same way with chosen locations. Registering an older relative’s home so warnings reach you is a genuinely useful ten minutes.
What do the Met Office warning colours mean?
Yellow means possible low-level impacts and is worth reading rather than dismissing; amber means an increased likelihood of disruption; red means dangerous weather is expected and you should act to keep yourself and others safe (Met Office, checked 29 August 2026).
Why did my phone just make a siren noise?
Almost certainly an Emergency Alert or a national test of the system. The sound and vibration last about ten seconds, and the message on screen says what is happening and what to do. Read it before you swipe it away.
