How many litres of water does your household need for 72 hours?
Official advice in the UK is now to be ready for three days without power, water or shops. Answer 8 quick questions and see the exact water, food and kit for your home, and how to build it a little each week, without panic buying and without waste.
Work out what my home needsTakes about 2 minutes. You see your numbers before paying anything.
A checklist tells you what. It does not tell you how much.
“Bottled water. Tinned food. A torch.” Sensible advice, but it leaves the real questions open. How many litres for two adults, a toddler and a dog? How many tins? What if your whole kitchen is electric? And how do you do it without spending £80 in one trip on food that goes out of date in the cupboard?
Steady72 turns the general advice into one specific plan for your home.

Litres of water, number of meals and the full list for 72 hours, worked out for your household.
Build it week by week
A short list to add to your normal shop, within your budget, until you are covered.
No bunker. No panic buying.
Three days of supplies is not about the end of the world. It is about ordinary problems, handled calmly, because the cupboard was already sorted.
The power is out all weekend
A storm brings the lines down. The hob, the kettle and the freezer all stop together.
The taps run dry
A burst main, and the nearest shop has sold out of bottled water by lunchtime.
The card machines stop
Payments go down for the day. No cards, no cash machines, and a queue at every till.

Questions people ask
Is this an official government service?
No. Steady72 is independent. Our water figure follows the published UK guidance of 3 litres per person per day for three days. Food counts, pet and baby amounts and prices are our own planning estimates, and we label them as such.
Do I have to buy a kit from you?
No. We do not sell supplies. Your plan is a list for your usual supermarket, and most of it is ordinary food.
What does it cost?
The questions and your household numbers are free. Full access to your plan in the app is a one-off payment of £9. No subscription.
Is it an app I download?
It runs in your browser and installs to your home screen in a couple of taps, on iPhone and Android. There is nothing to download from an app store.
