A practical UK car emergency kit costs roughly £30-£50 to assemble and should include a warning triangle, hi-vis vest, torch, jump leads or a jump starter pack, a tyre inflator/sealant kit (many modern cars no longer carry a spare wheel), a basic first aid kit, and a phone charger. In winter, add a blanket, ice scraper and a small shovel.
At a glance
| Item | Why it matters |
|---|---|
| Warning triangle | Legally required in many European countries; useful (though not legally required in the UK) to warn traffic if stopped on a hard shoulder or verge |
| Hi-vis vest | Improves visibility if you need to exit the vehicle on a roadside |
| Jump starter pack/jump leads | Restarts a flat battery without needing another car and driver |
| Tyre inflator/sealant kit | Many modern cars have no spare wheel — check what your car actually carries |
| Phone charger/power bank | Keeps your phone charged to call for breakdown assistance |
Check what your car already carries
Many newer cars are sold with a puncture repair kit (sealant and inflator) rather than a spare wheel, to save weight and space — check your boot before assuming you have a spare. If you don't, consider whether to buy a compatible space-saver spare separately or rely on the inflator kit plus breakdown cover for anything a sealant can't fix, like a sidewall puncture.
The core kit
- Warning triangle — not a legal UK requirement (unlike much of mainland Europe) but genuinely useful for warning approaching traffic if you're stopped somewhere hazardous.
- Hi-vis vest — keep it inside the cabin, not just the boot, since you should ideally put it on before getting out of the car in poor visibility or on a motorway hard shoulder.
- Jump starter pack — a compact lithium jump-start pack (from roughly £30-£60) means you're not dependent on flagging down another driver for jump leads.
- Torch (with spare batteries or hand-crank/rechargeable) for breakdowns after dark.
- Basic first aid kit — plasters, bandages, antiseptic wipes.
- Phone charger or power bank — a dead phone during a breakdown turns a minor inconvenience into a genuine problem.
Winter additions
- Ice scraper and de-icer, kept in the cabin (not the boot) so they're accessible on a frozen morning.
- A blanket or two, particularly if you regularly drive rural or exposed routes in winter.
- A small folding shovel if you drive in areas prone to snow.
- High-visibility, weatherproof clothing and sturdy footwear if you might need to walk for help.
What to do if you break down
If possible, get the car off the live carriageway — onto a hard shoulder, layby or exit slip. On a motorway, exit the vehicle from the passenger side away from traffic if it's safe to stop on the hard shoulder, put on your hi-vis vest before getting out, and stand well back from both the carriageway and your vehicle behind a barrier where possible while you call for help.
Smart motorways without a permanent hard shoulder pose particular risk if you break down in a live lane — if you can't reach a refuge area, keep your hazard lights on, stay belted in with seatbelts on, and call 999 immediately rather than trying to exit the vehicle.
