The principle: build from genuine needs, not fear. The UK Government advises households to consider supplies for an emergency lasting a few days. Seventy-two hours is a useful planning target—not a guarantee that every incident will end after three days.
Start with a plan, not a shopping list
Plan for your actual household and risks
Count the people normally at home and note babies, older relatives, disabilities, allergies, dietary restrictions, regular medicines and power-dependent medical equipment. Add pets, working dogs and livestock. Then consider realistic local disruptions: power or water failure, storm damage, snow, flooding, blocked roads or a temporary instruction to stay indoors.
A hill farm, isolated cottage and village terrace will not need identical kits. Distance to shops, water source, heating type, private pumps, road access and mobile coverage should shape the contents.
Separate home, grab-bag and vehicle needs
The home kit supports you while staying safely at the property. A small grab bag holds only what you may need if authorities tell you to leave quickly. A vehicle kit covers delays, breakdowns and winter conditions. Trying to make one enormous bag do all three jobs usually creates something too heavy, incomplete or left in the wrong place.
Never delay escape from a fire to collect a bag. Leave immediately, stay out and call 999.
| Kit | Main purpose | Keep it realistic |
|---|---|---|
| Home kit | Manage several days of utility, weather or access disruption | Water, food, light, radio, power, hygiene, first aid and household-specific supplies |
| Grab bag | Support a prompt evacuation when instructed | Documents, medicines, contacts, charger, torch, basic clothing and immediate essentials |
| Vehicle kit | Deal with being delayed or stranded | Warm layers, high-visibility clothing, torch, charger, drink, food, first aid and seasonal equipment |
Build the core 72-hour supplies
Build a realistic drinking-water reserve
Current UK Government guidance cites a minimum of 2.5–3 litres of drinking water per person per day for survival. For 72 hours, that is 7.5–9 litres per person. More is needed for cooking and basic hygiene; the guidance notes that 10 litres per person per day is more comfortable. Babies, some medical needs, hot weather, physical work and animals increase demand.
Water is heavy, so build in stages. Start with the three-day drinking minimum, then add practical cooking and hygiene capacity. Use sealed food-safe containers, follow their storage instructions, protect them from contamination and rotate them.
Choose normal food that needs no cooking
Select shelf-stable food the household already eats: ready-to-eat tins or pouches, fruit, crackers or oatcakes, nut or seed products where suitable, long-life alternatives and snacks. Include a manual tin opener, cutlery and any dietary substitutes. Ready-to-feed infant formula is safer when water cannot be boiled or bottles sterilised.
Plan simple portions rather than buying novelty “survival meals”. Keep food together with its preparation needs, check allergy labels and rotate items into normal meals before their dates expire. Include pet food separately.
Plan medicines and first aid properly
Keep enough regularly prescribed medicine to avoid running out during a short disruption, while following the prescriber's, pharmacist's and storage instructions. Do not change doses or create an unofficial stockpile. Maintain a paper medication list, allergies, relevant conditions, prescription details and clinical or equipment contacts.
A household first-aid kit can include waterproof plasters, sterile dressings, bandages, gloves, medical tape, antiseptic, eyewash, a thermometer and tweezers. Add only items you know how to use, check expiry dates and learn basic first aid.
Add safe light, power and information
Use battery or wind-up torches—official guidance says torches are safer than candles. Add spare batteries in their packaging, a tested power bank for each essential phone or device, the correct charging leads and a battery or wind-up radio. A head torch is particularly useful for rural tasks that require both hands.
Write down local and national radio frequencies, emergency contacts and the power-cut numbers: 105 in England, Scotland and Wales; 03457 643643 in Northern Ireland. Preserve phone charge rather than relying on its torch continuously.
Prepare warmth, hygiene and sanitation
Keep warm layers, socks, hats, blankets and waterproof clothing accessible. Add hand sanitiser, wet wipes, toilet paper, refuse sacks and personal hygiene products. Households with young children may need nappies and disposal bags; people with continence, stoma or other care needs should add their normal supplies.
Do not treat a barbecue, camping stove or portable generator as an indoor heating or cooking solution. Fuel-burning appliances can create fatal carbon monoxide and many are designed for outdoor use only.
Add the details that make the kit usable
Protect contacts, documents, keys and cash
Keep a paper household emergency plan with contact numbers, medicines, radio frequencies, insurance details, utility numbers, meeting points and the property's full address. Store copies of essential documents securely and know where originals are. Add labelled spare keys only where their storage does not undermine security.
A small amount of cash can help if local card systems are unavailable, but do not keep a conspicuous or excessive sum in the kit. Protect sensitive papers and money from moisture and unauthorised access.
Include individual and accessibility needs
Adapt the kit for mobility, sensory, communication and cognitive needs. This may include spare glasses, hearing-aid batteries, communication cards, mobility-equipment chargers, continence products or familiar comfort items. Keep paper instructions for medical devices and test only manufacturer-approved backup batteries.
Register for relevant utility Priority Services Registers if eligible and agree who will check on anyone needing extra support. Make the kit reachable; a well-stocked box on an inaccessible shelf is not a solution.
Cover pets, livestock and rural systems
Store appropriate food, drinking water, bowls, leads, carriers, medication, waste bags and identification details for pets. Keep veterinary and animal-care contacts on paper. Livestock plans should cover water, feed, safe access and any equipment that depends on power, but the scale will normally require a separate property plan rather than a domestic box.
If the property relies on private water, pumps, treatment equipment, electric gates or heating controls, link the kit to clear manual procedures, release tools and professional contacts. Do not assume the household water reserve can also meet large-animal needs.
Store and label everything safely
Use manageable, clearly labelled containers in a dry place that remains accessible during a power cut. Split heavy water from lighter supplies. Keep medicines, batteries, sharp items, matches and chemicals safely away from children and animals, and follow manufacturers' temperature and storage instructions.
Put the most frequently needed items—torch, radio, paper plan and first aid—at the top. Do not block escape routes, utility controls or fire-safety equipment.
Inspect, rotate and practise twice a year
Choose two memorable dates each year to check water, food, medicines, first-aid items, batteries, power banks, clothing sizes, documents and animal supplies. Rotate food into normal use and replace it with fresh stock. Recharge power banks and test torches and radio.
Run a short household exercise: find the kit in darkness, tune the radio, open the grab bag, locate the gate release and review who contacts neighbours. Record gaps without turning the exercise into a drama.
What should the first version cost?
Start with items already owned: warm clothes, blankets, ordinary cupboard food, a torch, charger, hygiene supplies and copies of information. Add drinking water, radio, power bank and first-aid gaps over several normal shopping trips. A reliable basic kit is more useful than an expensive collection of specialist equipment nobody has tested.
A realistic starter kit for tonight
- One tested torch, spare batteries and a charged power bank.
- At least the first stage of a 7.5–9 litre three-day drinking-water reserve per person.
- Three days of normal, shelf-stable food that needs no cooking.
- A manual tin opener, basic cutlery and essential hygiene supplies.
- Regular medicines managed correctly, a medication list and a checked first-aid kit.
- Warm layers, blankets and waterproof clothing.
- A battery or wind-up radio and paper emergency contacts.
- Household-specific baby, disability, pet and rural-property essentials.
Tip: print this page, mark what you already own and build the remaining items gradually.
