A boil-water notice is one of those UK disruptions that looks simple until you are trying to keep a household running around work, school and medication. The priority is clean storage, a reliable way to boil water if the hob is unavailable, and a backup treatment method for water that cannot be boiled immediately.
This kit starts with purification tablets and a proper water container, then adds a higher-capacity purifier, a simple butane stove and fuel for outdoor boiling, and an insulated flask so safe hot water stays usable for longer. It is designed for short mains-water incidents, burst pipes, local contamination notices and winter supply problems rather than wilderness water collection.
Chemical tablets that kill bacteria, viruses, and parasites in water. Lightweight backup to mechanical filtration.
Chlorine dioxide is most effective and leaves least taste. Iodine works but has a stronger flavour.
Most tablets need 30 minutes for bacteria. Cryptosporidium may need 4 hours.
Unopened tablets last 4–5 years. Check expiry dates regularly.
Drinking before the treatment time is up means you’re drinking unsafe water.
Chemical reactions slow in cold water. Double the treatment time below 5°C.
Chlorine dioxide tablets that treat questionable water to make it safer to drink. A tiny, long-life backup for when filtering or boiling isn't possible.
Fifty compact tablets that make questionable water safe to drink when you can't boil or filter it. Each treats around a litre, so a single pack covers weeks of emergency use and weighs almost nothing in a grab bag. A cheap, long-life backup to keep alongside a proper filter, not instead of one.
A BPA-free 8-litre water carrier that folds flat when empty, so it takes up almost no room until you actually need to store or move water. Handy to keep in a cupboard for a supply interruption, or in the car for camping and days out. The carry handle and tap make pouring and hand-washing straightforward.
A rugged 18.5-litre jerrycan with a built-in ultrafiltration cartridge that removes viruses, bacteria and cysts as you pour. Fill it from a rain butt, stream or standpipe and it delivers clean drinking water for a household — up to 20,000 litres per cartridge, with no power or chemicals.
A single-burner butane stove that runs on Campingaz CP250 cartridges, giving you a stable 2,200W ring for boiling water or cooking a hot meal when the power is off. It sits flat on a sturdy outdoor surface and packs into its own carry case, which makes it a practical backup for camping and longer winter outages.
Eight Campingaz CP250 valve cartridges — the resealable, puncture-proof type used by Campingaz Bleuet stoves and lanterns. Worth stockpiling so an off-grid stove or lantern keeps running through a long power cut or a run of camping trips. Only fits appliances built for the CP250 valve fitting, not screw-thread EN417 burners.
A rugged stainless steel vacuum flask that keeps drinks hot for up to 24 hours and cold for 24 hours. The 1.2L size suits a household through a power cut, with a leak-proof stopper and an insulated cup lid for sharing a hot brew.
