UK government advice

Why three days?

In October 2026 the UK government launched Be Ready, its advice to households on getting through an emergency. It asks everyone to be ready to manage for three days, so you can cope while support reaches those most in need. France, Ireland and the Netherlands give the same advice.

Our booklet and short videos take you through it one topic at a time. You don't need to buy everything at once, and you probably have some of it at home already.

Getting started

Start small

  1. 1

    See what you already have

    Check your cupboards first. You probably have some of what you need.

  2. 2

    Plan for your household

    Note down what you still need, including things your family relies on such as medicines, baby formula or pet food.

  3. 3

    Build it up gradually

    Pick up a missing item or two on your regular shop to spread the cost.

  4. 4

    Check it every six months

    Swap out anything near its expiry date, and update your supplies if your household's needs change.

  5. 5

    Talk to your neighbours

    Swap contact details and agree what you could share during an outage.

How to prepare for water shortages in an emergency

Store enough water

Keep 3 litres of bottled drinking water per person per day, for three days. That is 9 litres each, or 36 litres for a family of four. You will need more for cooking and washing.

  • During an outage, save bottled water for drinking, washing your hands and preparing food.
  • If you have an outside space, a water butt can collect rainwater for flushing toilets. Never drink it.
  • Ready-made or ready-to-feed baby formula is safest, as you may not be able to boil water or sterilise bottles.
  • If your water company issues a boil-water notice, follow its instructions until it's lifted.
  • If you're on your water company's Priority Services Register, it will arrange other supplies for you.

Best way to stockpile food to prepare for an emergency

Build up a food supply

Keep enough food for three days that doesn't need a fridge or cooking, such as tinned meat, fish or vegetables, dried fruit and nuts. It's best to buy food your household already eats.

  • Pick up an extra item or two on your regular shop to spread the cost.
  • Keep a manual tin opener with your supplies.
  • Remember anyone on a special diet, baby food and pet food.
  • Check dates every six months, and eat and replace anything close to expiring.
  • In a power cut, keep the fridge and freezer shut. A fridge stays cold for up to 4 hours, and a full freezer keeps food frozen for up to 48 hours (24 if half full).

How to prepare and stay safe during a power outage

Get ready for a power cut

Report a power cut by calling 105 for free in England, Scotland and Wales, or 03457 643643 in Northern Ireland.

  • Keep a torch and spare batteries. Torches are safer than candles.
  • Keep a charged power bank for phones or medical devices.
  • Keep some cash in coins and notes, as card payments and cash machines may stop working.
  • If you suspect carbon monoxide, call the free National Gas Helpline on 0800 111 999.
  • Check on your neighbours and, if you can, share blankets, warm clothes or food.

Simple hygiene steps to take in an emergency

Keep clean when water is short

Good hygiene stops infections spreading when clean water and normal services are disrupted.

  • Keep hand sanitiser, wet wipes and your usual hygiene and bathroom products.
  • Wash your hands in a clean washing-up bowl of water with soap or household disinfectant.
  • Use bottled water only for drinking, handwashing and preparing food.
  • Use collected rainwater for flushing toilets, never for drinking.
  • If you have a baby, keep extra nappies and wipes.

How to use basic first aid to protect a life in an emergency

Learn basic first aid

A few first aid skills mean you can help someone until professional help arrives.

  • Keep a first aid kit at home with sterile dressings, plasters, bandages, disposable gloves, cleansing wipes, tape, scissors and a foil blanket.
  • Download the British Red Cross's free First Aid app. It covers more than 20 skills and works without an internet connection, and a Baby and Child app covers 17 more.
  • The British Red Cross runs free first aid workshops for adults and online sessions for anyone aged 10 or over.
  • Teach children how and when to call 999.
  • In a life-threatening emergency, call 999. If you can't get through, try both a mobile and a landline.

How to manage everyday health problems in an emergency

Don't run out of medicine

Make sure you have the medicines and medical supplies your household relies on.

  • Order repeat prescriptions up to 5 working days before you need them.
  • Keep a written list of everyone’s regular medicines and doses with your plan.
  • If you run out in England, NHS 111 online can arrange an emergency supply of a regular repeat medicine at your usual prescription charge.
  • For urgent advice, use NHS 111. Text relay users can call 18001 111, and there is a British Sign Language service.
  • If someone in your home is disabled, keep spares of what they rely on, such as hearing aid batteries or mobility aids.

A guide to effective communication in an emergency

Stay informed and in touch

If an emergency happens outside, go in, stay in and tune in. If it is inside, get out, stay out and ring 999.

  • Keep a battery or wind-up FM radio and write down the frequencies of your local stations.
  • Write important numbers on paper, including family, neighbours, your GP and your utility companies.
  • Agree a meeting point with your family in case you are separated.
  • Swap numbers with neighbours and think about setting up a messaging group.
  • An Emergency Alert makes a loud, siren-like sound on your phone for about 10 seconds, even on silent. Stop and follow the instructions, and if you are driving, find somewhere safe and legal to stop first.

Looking after your family's wellbeing during a crisis

Look after your family's wellbeing

Emergencies are stressful, and children pick up on how the adults around them are reacting.

  • Keep to regular routines where you can, especially around meals and exercise.
  • Talk to children calmly and honestly. Listen more than you speak, let their questions guide the conversation and remind them that people are helping each other.
  • If the news is making you anxious, check it once a day.
  • You can call Samaritans free on 116 123 at any time, or text SHOUT to 85258.
  • If difficult feelings last longer than 2 to 4 weeks, speak to your GP or refer yourself to NHS Talking Therapies.

Across Europe

What other countries advise

Governments across Europe have sent households similar advice in the last two years. Sweden and Norway ask for a week, and Germany suggests 10 days if you can. Some booklets, such as Sweden's, talk openly about war, while the UK's advice focuses on everyday emergencies like storms and power cuts. The basics are the same everywhere.

Frequently asked questions

Be Ready is the UK government's advice to households on preparing for emergencies. The Cabinet Office published it on 22 October 2026 as the first stage of a three-year campaign. It asks households to be ready to manage for three days of disruption, such as a storm that cuts off power, water or phones.
The government advises 3 litres of drinking water per person per day for three days, which is 9 litres each. A family of four would need 36 litres. You will need more for cooking and washing.
Check what you already have, then pick up missing items on your regular shop to spread the cost. If you can only do a few things, the British Red Cross suggests starting with essential medication, then drinking water, food, a way to stay informed, a way to stay connected and a simple household plan.
Call 105 for free in England, Scotland and Wales, or 03457 643643 in Northern Ireland. Use a torch rather than candles and keep the fridge and freezer closed. A fridge stays cold for up to 4 hours, and a full freezer keeps food frozen for up to 48 hours (24 if half full).
Order repeat prescriptions up to 5 working days before you need them. If you run out in England, NHS 111 online can arrange an emergency supply of a regular repeat medicine at your usual prescription charge.
It is a free service in England, Scotland and Wales that tells energy and water companies who may need extra help. Members get priority support in an emergency and, wherever possible, notice of planned power cuts. You can join if, for example, you have reached state pension age, are pregnant or have young children, are disabled or have a long-term condition.
Your phone makes a loud, siren-like sound for about 10 seconds, even on silent. Stop what you're doing and follow the instructions, but if you're driving, find somewhere safe and legal to stop first. Alerts are free, need no sign-up and work on UK 4G and 5G networks.
Advice varies. Sweden and Norway ask for at least a week, and Germany suggests 10 days if possible. The UK asks for three days, as France, Ireland and the Netherlands do. The European Commission treats 72 hours as a minimum and describes preparing as a precaution rather than a response to a specific threat.
