Most home first aid kits in the are bought, put in a cupboard, and forgotten until someone needs a plaster and discovers everything in the kit expired three years ago. The kit then gets replaced with a similar one. The cycle continues.
The honest answer: a £20 kit covers most household needs, and the practical work isn't buying it, it's checking it twice a year and using anything that's about to expire on minor cuts before it goes off.
What UK households actually need
A practical home first aid kit:
| Item | Why | Replace |
|---|---|---|
| Plasters (assorted, waterproof) | Most-used item by orders of magnitude | Roll over rather than expire |
| Sterile gauze pads | Larger cuts | 3-5 years; check sealing |
| Crepe bandages | Sprains, holding gauze | Roll over; cleaner each year |
| Triangular bandage | Slings, bigger wraps | Indefinite if sealed |
| Disposable gloves | Hygiene during first aid | 5 years from manufacture |
| Antiseptic wipes | Cleaning around wounds | 3-5 years |
| Saline pods | Eye irrigation, wound cleaning | 2-3 years |
| Tweezers | Splinters, ticks | Indefinite |
| Scissors (blunt-end) | Cutting tape and bandages | Indefinite |
| Safety pins | Securing slings, dressings | Indefinite |
| Burn gel sachets | Minor burns | 2-3 years |
| Adhesive medical tape | Securing dressings | 3-5 years |
| Foil/space blanket | Shock, hypothermia | Indefinite if sealed |
| First aid leaflet | Yes, actually | Replace yearly with current edition |
Total cost if buying separately: around £20-£25. A pre-assembled BSI 8599-1-compliant kit is about the same price.
BS 8599-1 is the standard
If you want a first aid kit you can also use in a workplace context: BS 8599-1 is the British Standard. Three sizes, small (up to 25 people), medium (50), large (100). For a home, the small size is appropriate.
Workplace law (HSE) requires UK employers to provide BS 8599-compliant kits in business premises. For homes, it's not legally required but it's a useful quality marker.
Kits sold as "first aid kit" without BS 8599 labelling sometimes contain items that look the same but fail the relevant standard tests. The £8 kit from a supermarket is often this, fine for plasters, less reliable for sterile gauze.
The honest car kit
Required by law in some EU countries; not required in the UK; still genuinely useful.
For a car kit:
- BS 8599-1 small motor kit (£18-£25, slightly different mix from home kit)
- Foil blanket
- Bottle of water (for cleaning wounds and emergencies)
- High-vis vest (legally required in some EU countries; useful here for accidents)
- Warning triangle (legally required in some EU countries)
UK drivers heading to Europe should add: warning triangles, high-vis vests for every passenger, breathalyser (France), hi-vis hat (Spain). Each country has slightly different rules. Check before crossing.
What works
For most UK households: Reliance Medical BS 8599-1 Small Workplace Kit at £18-£25. Common, compliant, and cheaper than buying components separately.
Add to it:
- A box of regular plasters (you'll restock these often)
- Calpol/paracetamol suspension (for households with children)
- Antihistamine tablets (Piriteze or Cetirizine generic, useful for stings, rashes)
- Hydrocortisone cream (1%) for insect bites and rashes
- Thermometer (digital, £8-£15)
Total around £35-£45 for a household kit that's genuinely useful.
For cars: St John Ambulance Standard Motoring Kit at £15-£20.
For adventure/walking households: an Adventure Medical Kits Mountain Series at £40-£70 covers more serious injury situations relevant to outdoor activity.
What the £80 "family premium kits" actually contain
Premium home first aid kits at £60-£120 typically contain:
- Standard BS 8599-1 contents (worth £20-£25)
- Premium carrying bag (£10-£15 cost)
- Branding (free)
- Marketing markup (£20-£40)
Not worth the price difference. The bag is nicer; the contents are the same.
What's not in standard kits but useful
A few items not in BS 8599-1 kits but worth adding:
- Gauze swabs (5x5cm pack), better than what's in the kit for absorbing blood
- Steri-Strips, for closing small cuts you'd otherwise see at A&E
- Instant cold pack, useful for sprains, knocks
- Small emergency torch, power cuts, finding things in dark corners
- Cling film, covers burns until medical help (genuine NHS recommendation)
What to avoid
- £5-£10 unbranded "first aid" kits with no BS 8599 marking (often expired stock)
- Expired stock generally, wound dressings lose sterile guarantee
- Putting cream/ointment in pre-bought kits (often missing; you should add what you actually use)
- Storing the kit somewhere no one knows about (defeats the point)
- Letting children play with kit contents (gloves, scissors, triangular bandages get scattered)
What kids' first aid kits get wrong
Children's first aid kits sold separately are often more about novelty/character branding than actual need. The same kit with the same items, a bit more brightly coloured, at 2-3x the price.
For families: have one good household kit. Children don't need their own.
The exceptions worth budgeting for separately:
- Calpol/paracetamol suspension (in date)
- Liquid ibuprofen suspension (in date)
- Plenty of children's plasters (more decorative; kids prefer them)
- Antihistamine syrup
- Insect bite relief
The first aid course mistake
Most UK adults have never done a first aid course. The free or low-cost ones (St John Ambulance, British Red Cross, sometimes through workplace) take 2-3 hours and teach the genuinely useful skills:
- Recovery position
- CPR basics
- Bleeding control
- Choking response
- When to call 999 vs 111
For about £25-£60 (or free through workplace), you'll be more useful in an actual emergency than the contents of any kit. The course is the better investment than the premium kit.
Options:
- St John Ambulance Essential First Aid (3 hours, £25-£40)
- British Red Cross First Aid (varies, often free at community centres)
- Workplace-provided courses (free for employees in many sectors)
- NHS Online "First Aid Champions" (free online)
Where to keep the kit
Counterintuitive recommendations from A&E nurses:
- Kitchen, most household injuries happen here (knives, burns, slips)
- Easily accessible to adults, harder for children
- Not in a high cupboard above hob (heat damages contents; awkward to reach in panic)
- Same place every time (people in panic forget where they "moved it to last spring")
A second small kit in the bathroom for first response is reasonable. A third in the car. Every other room is overkill.
What to do when something gets used
Restock immediately. The most common failure mode of home first aid kits is that someone uses the last sterile gauze on a Saturday and the kit sits empty for 18 months until needed again.
Keep a list of what's in the kit (most BSI kits include one). When you use something, mark the list, restock at the next supermarket trip.
Twice a year, same days you change smoke alarm batteries, check expiry dates and replace anything within 6 months of expiry.
