A first aid kit is the one bit of preparedness you hope stays unopened, and the one you'll be very glad to have the day it isn't. Most households own one — often a dusty tin with a few odd plasters — but a kit only helps if it holds the right things, you can find it fast, and nothing in it has expired. This guide covers what the different types of kit are really for, which contents earn their place, what to add yourself, and how to size a kit for the home, the car and a rucksack without overspending on things you'll never use.
BS 8599, travel kits and outdoor kits — what the labels mean
UK first aid kits broadly fall into three families. BS 8599 kits are the British Standard workplace kits, sized small, medium and large by number of people, and they're a reliable, well-stocked baseline for the home too — buying a 'medium BS 8599' takes the guesswork out of contents. Travel and motoring kits are more compact and lean towards plasters, wipes and a few dressings — fine for a handbag or glovebox, light on serious injury cover. Outdoor and adventure kits add blister care, blister plasters, tape, a triangular bandage and sometimes a foil blanket, aimed at walkers and campers. There's no single 'best' — match the kit to where it lives and what's likely to happen there.
What actually gets used
Ignore the impressive-looking piece count and look at the everyday items, because those are what you'll reach for. Plasters in a range of sizes, sterile dressings and wound pads for bigger cuts, adhesive tape, antiseptic wipes, tweezers, scissors and a few pairs of disposable gloves cover the vast majority of household incidents. Blister plasters are worth their weight for anyone who walks. A cheap kit stuffed with fifty identical small plasters and little else looks generous and isn't; a kit with fewer, more varied items is usually the better buy.
What to add yourself
Almost no off-the-shelf kit is complete for a real household. Add any personal and prescription medicines your family relies on, plus everyday painkillers, antihistamines and rehydration salts for tummy upsets and heat. A small bottle of hand sanitiser and extra nitrile gloves keep things hygienic when there's no clean water. If anyone in the house has a serious allergy, asthma or a condition needing specific medication, that kit or those meds should live with the first aid supplies and be in date. Building a kit around your own household is what turns a generic box into something genuinely useful.
When to think about bleed control
Standard kits handle cuts, grazes and sprains but not serious bleeding. If you spend time somewhere far from help — remote walking, working with tools or power equipment, or you simply want to be ready for the worst — it's worth adding a trauma dressing and, if you're trained to use one, a tourniquet. These are not everyday items and they need a little knowledge to use safely, so pair them with a first aid course rather than buying them and hoping. For most homes the standard contents plus a good dressing are plenty; the trauma add-ons are for specific higher-risk situations.
One kit or several?
Most households are best served by more than one kit sized to where it lives: a comprehensive kit at home where you can lay everything out, a compact kit in each car, and a small kit in the walking or grab bag. Duplicating the basics is cheap and means you're never caught out because the only kit is in the other car. Keep the home kit somewhere every adult knows about — a fixed cupboard, not wherever it was last left — and don't lock it away so well that it can't be found in a hurry.
Maintenance and knowing how to use it
A first aid kit is not a buy-once item. Dressings, wipes, medicines and even plasters have expiry dates, and a kit that's been raided for the odd plaster over two years is half-empty when you need it. Check it when the clocks change, replace what's been used or expired, and keep it topped up. Most importantly, the kit is only as good as the person holding it — a short first aid course (St John Ambulance, British Red Cross or your workplace) is worth far more than an expensive kit you don't know how to use. Buy a sensible kit, tailor it to your household, keep it stocked, and learn the basics. See the related gear below to build and top up your kit.
