The short version

Quick answer

A 72-hour kit should cover 3 litres of drinking water per person per day, no-cook food, a torch, a battery or wind-up radio, a charged power bank, first aid, your medication, cash, warm layers and copies of documents.

Water: plan 3 litres per person per day

Be Ready advises 3 L of drinking water per person per day for 3 days, with more for cooking and washing. The British Red Cross gives 2.5 to 3 L. Purification tablets and filters treat water you already have; they do not replace stored water.

  • Store sealed water where it stays cool and dark, and note the earliest date.
  • Split it: some in a grab bag, the rest at home.
  • Add extra for babies, pets, hot weather or illness.

Pre-packed or build your own?

Pre-packed kit

  • Done in one order, packed in one bag.
  • Fixed sizes: shared items like a torch and radio don't scale with people.
  • Check the listed water volume against 3 L per person per day; most bags carry far less.
  • You may pay for things you already own.

Build your own

  • Sized to your household, ages, medical needs and pets.
  • Uses food you actually eat, rotated into normal meals.
  • Start with what you own; spread the cost over normal shops.
  • More effort, and easy to leave half-finished.

Our take (editorial guidance, not a test result): build from what you already own, then add the missing pieces, starting with water.

What you add yourself

  • Your essential medication and a written list of it
  • Cash in small notes
  • Copies of important documents
  • Written phone numbers and your household plan
  • Baby supplies: ready-to-feed formula and nappies
  • Pet food and water
  • Spare keys and glasses

Grab bag or home kit?

A grab bag is what you take if you are told to leave home, for example in a flood. A home kit is what you need to stay put through a power cut or storm.

If there is a fire, get out, stay out and call 999. Don’t waste time rescuing valuables (GOV.UK: fire safety in the home).

Packing a leave-home bag

Power cut specifics

  • Call 105 to report a power cut in England, Scotland or Wales.
  • Join the Priority Services Register if someone at home relies on power for medical equipment.
  • Digital landlines may stop working in a power cut: keep a charged mobile.
  • Never use camping stoves, gas heaters or barbecues indoors.

Storage and rotation

  • Check the kit every 6 months, as Be Ready advises.
  • Note the earliest expiry date on food, water and first-aid items.
  • Recharge power banks and test torches and radios when you check.
  • Keep it somewhere you can reach in the dark: under the stairs, a wardrobe floor or near the door.

Questions

How much water does a 72-hour kit need?

3 litres per person per day for 3 days: 9 litres per person, more for babies, pets and hot weather.

Is a 72-hour kit a legal requirement?

No. Be Ready is government advice to be ready for 3 days of disruption, not a legal duty.

Are grab bags the same as home kits?

No. Grab bags are for leaving home quickly; home kits are for staying put. Many households need both.

Why don't you show a price for every product?

We only show an Amazon price that comes from Amazon's own product data and is less than 24 hours old. Prices change, so check on Amazon.
