Why a grab bag earns its place by the front door

Most home evacuations in the UK are not the stuff of disaster films. A burst water main, a gas leak, a kitchen fire that spreads into the roof space, or a police cordon after an incident nearby can all mean leaving at short notice and not being allowed back for hours. In that moment you will not be thinking clearly, and the last thing you need is to be searching drawers for your passport while a neighbour tells you to leave now.

A grab bag — sometimes called a go bag or an evacuation kit — solves that problem in advance. Everything you would hate to lose, plus everything you would need for a day or two away from home, lives in one rucksack you can pick up with one hand and carry a mile if you have to. Pack one for every member of the household, including children old enough to carry a small bag of their own. Even a five-year-old can manage a lightweight bag with a spare jumper and a favourite toy inside.

Choose a bag you can actually carry

A 20–30 litre rucksack suits most adults: big enough for the essentials, without tempting you to pack half the house. Look for wide padded shoulder straps and a fabric that will survive being dragged across a wet pavement. Keep the total weight under about 5kg for an adult and 2–3kg for a child, because you may be walking further than you expect.

• Waterproof the contents with a dry bag or a couple of sturdy freezer bags inside the rucksack.
• Store the bag within a few steps of the door you would leave by — not in the loft, and not behind the Christmas decorations.
• Attach a small torch to the strap with a short cord so you always know where it is.
• Label the bag with a name and mobile number, and show every adult in the house where it lives.

Documents, cash and the paperwork that is hard to replace

This is the heart of the kit. Replacements take weeks and cost money, and some items are genuinely painful to reconstruct in the middle of a crisis. Take photocopies rather than originals wherever you can.

• Copies of passports, driving licences, birth and marriage certificates, and insurance policies.
• A note of bank account numbers and the phone numbers for your bank, GP surgery and home insurer.
• A small USB stick with scanned copies of the same documents, plus a few family photographs.
• Cash — £50 to £100 in small notes and a handful of coins. Card machines and cashpoints are often the first things to fail.
• A printed list of emergency contacts, because phone batteries die and screens crack.
• Spare house and car keys, kept in a pouch rather than loose in the base of the bag.

Medication and personal care

Prescription medicines are the item people most often forget and most urgently need. Ask your pharmacist about ordering an extra supply for the bag if your medication is stable and repeat-prescribed, and keep a written list of what you take. Do not let the bag become your main supply — rotate it so nothing goes out of date.

• At least a week of regular medication where possible, in labelled packaging.
• Inhalers, adrenaline auto-injectors, insulin and testing strips, with a note of how each is used.
• Spare glasses or contact lenses, and a copy of your prescription.
• A basic first aid kit: plasters, antiseptic wipes, painkillers and blister plasters.
• Toothbrush, toothpaste, soap, hand sanitiser, sanitary products, and nappies or wipes if you have small children.

Warm clothing, light and power

Assume you may be standing outside or in a community hall with the heating off, possibly in the rain. British weather is rarely more dangerous than inconvenient, but a wet, cold hour is miserable and avoidable.

• A full set of spare clothes in a plastic bag: socks, underwear, a warm layer and waterproof trousers if you have them.
• A fleece, hat and gloves for each person — warmth matters more than fashion.
• A compact waterproof jacket that lives in the bag rather than on a coat hook.
• Sturdy shoes or trainers, kept beside the bag if they are too bulky to go inside.
• A phone charger and a charged power bank, with a short charging cable.
• A torch or head torch with spare batteries, and a small battery or wind-up radio.
• A refillable water bottle and a few high-energy snacks — nuts, cereal bars or boiled sweets.

Keep it ready without letting it rot

A grab bag is only useful if it works when you need it. Check it twice a year, and use the clock changes in spring and autumn as your reminder. Replace out-of-date medication, swap children's clothes for a bigger size, recharge the power bank and test the torch batteries.

Finally, tell everyone in the household what the bag is for and where it lives. A short conversation at the kitchen table, a practice walk to the front door, and an agreed meeting point if you get separated will do more good than any amount of extra kit. Preparedness is mostly a matter of a few small decisions made calmly, in advance.
