You do not need to spend hundreds of pounds. Be Ready asks households to be ready for three days of disruption. Building up slowly spreads the cost. A simple monthly plan keeps each shop small, and nothing here needs a big one.
The weekly figure is a target, not a price. Prices change, so check the current price in your shop. If a week costs less, bank the saving. If it costs more, move an item to next week.
Week 1: light and a tin opener
Budget: about £5.
- A simple AA or AAA LED torch (Retailer link coming soon), plus spare batteries stored apart from it.
- A manual tin opener (Retailer link coming soon) if yours fails a test on a tin; otherwise wait a week.
Free steps for this week: find every torch you own and test it, and charge your phone. Our guide to emergency preparedness for free has more.
Week 2: food you can eat cold
Budget: about £5.
Buy a few items you already like and would eat in a power cut, such as tinned beans (Retailer link coming soon), fish, fruit and crackers. Choose ring-pull tins where you can. Put the oldest at the front. Be Ready advises keeping three days of non-perishable food per person, so add a little more each week rather than buying it all at once.
Free steps: list what you could eat for three days without cooking, and note the gaps.
Week 3: water and warmth
Budget: about £3 to £5 or free.
Water is the most important item and the cheapest. Clean, food-grade bottles or containers filled from the tap work. Be Ready advises 3 litres per person per day, so a household of two needs about 18 litres for three days. Our guide to how much water to store explains the sums. Swap the water about every six months.
For warmth, gather blankets, coats, hats and gloves you already own into one place. Do not buy a heater. Never use a camping stove, barbecue, gas heater or generator indoors to warm a room.
Week 4: first aid and a written plan
Budget: about £5.
- A pack of assorted plasters and dressings (Retailer link coming soon), if your first aid shelf is bare. Speak to your GP or pharmacist about medicines for your household. Do not stockpile prescription medicines beyond what a clinician agrees.
- Optionally a whistle (Retailer link coming soon), a small spend that makes a loud noise.
Then write your plan. It takes twenty minutes. Our household emergency plan shows how. Write down six numbers: 999, 111, 101, 105, a family contact and your GP. Add the National Gas Emergency Service number, 0800 111 999 (Great Britain; Northern Ireland: 0800 002 001).
After month one
You now have light, food, water, warmth and a plan. Keep going slowly:
- Put a reminder in your calendar for a monthly 15-minute check.
- Add a battery radio or power bank when you can.
- Grow the food cupboard by one or two items per shop.
- Read our £25 starter kit guide for a one-off alternative.

- Decide which week you start and mark it on the calendar.

- Fill two or three clean drinks bottles or food-grade containers with tap water and write the date on them.
- Write the six numbers on a card.
If you have £10, £25 or £50
These are budgets, not quotes. Check the current price first.
- About £10: weeks one and two together.
- About £25: the first month in one go, then top up.
- About £50: add a second light, a radio or a power bank.
Questions people ask
How much does it cost to start prepping in the UK?
You can start for nothing by using what you own. A basic kit of a torch, tin opener, some tins and plasters costs roughly £20 to £25 if you build it over a month, but check the current price in your shop.
What should I buy first when prepping on a budget?
Light first, then food you can eat cold, then water containers, then first aid and a written plan. In our view, that order covers the disruptions most households meet, such as a power cut or a short water outage.
Is it worth prepping if I only have a small budget?
Yes. Most of the value comes from free steps, such as knowing where your stopcock is, writing numbers down and filling containers with tap water. Small, steady purchases then close the gaps.
How long does it take to build a basic kit?
About a month at £5 a week, following the order in this plan. Be Ready suggests three days of supplies, so you can keep adding after the first month at your own pace.
