How to Cook Without Electricity UK: Power Cut Plan

Before you think about cooking anything, protect the food you already have. Keep the fridge door shut: a closed fridge holds a safe temperature for around four hours, and a full, unopened frozen food compartment keeps its contents solid for roughly 24 to 48 hours. Every time you open the door you lose cold air, so decide what you want before you reach in.

Next, check what still works. Call 105 from any phone to reach your network operator and get an estimated restoration time. A two hour outage needs nothing more than sandwiches and a flask. A two day storm outage is a different job, and the rest of this guide covers it.

If you have a gas hob, test it now with a match rather than assuming it is dead. Many UK gas hobs only use electricity for the spark igniter, so the burners themselves still work when lit by hand. Gas ovens with electronic controls and fan assistance usually will not run, and a combi boiler will not fire without power, so plan around hob-top cooking only.

The easiest hot-meal problem to solve is the one you avoid entirely. A sensible UK store cupboard covers two full days of eating with zero heat:

• Tinned fish, cooked meats and beans: protein that keeps for years and needs nothing but a tin opener. Keep a manual opener in the drawer, a ring-pull-only cupboard runs out of luck eventually.
• Oatcakes, crackers, wraps and long-life bread: the base for quick meals without a toaster.
• Nut butters, hard cheese, UHT milk: calorie-dense and happy at room temperature, cheese keeps well for a day or two out of the fridge if it stays cool.
• Fruit, dried fruit, nuts, cereal bars: snacks that keep morale up, which matters more than people expect on day two.
• Overnight oats: oats soaked in UHT milk make a proper breakfast with no heat at all.

Build meals, not just snacks: tuna and bean wraps, cheese and oatcakes with chutney, rice pudding straight from the tin. Our emergency kit list includes a two day no-cook menu you can copy onto one sheet of paper.

When a storm is forecast, fill every vacuum flask in the house with boiling water before the lights go out. A decent 1 litre flask keeps water hot enough for tea, instant coffee, instant soup, noodle pots and baby bottle warming for eight to twelve hours. Two large flasks cover a family for a full evening and the next morning.

A wide-mouth food flask goes further. Pour in boiling water, leave it two minutes to warm the steel, tip it out, then load it with just-cooked porridge, stew or pasta. It will still be properly hot at lunchtime. You can also cook in one: couscous, instant noodles and quick oats all cook from a kettle pour inside a preheated food flask.

The flask method has no flame, no fumes and no risk, which is why it comes before any stove in this guide. It pairs naturally with the one-warm-room approach in our guide to heating a room without electricity: hot food and drink do real work keeping people comfortable when the heating is off.

This is the question that matters most, so here is the honest answer. Official UK guidance is blunt: the NHS says do not use a barbecue or camping stove indoors, because burning gas in an enclosed space can build up carbon monoxide, a gas you cannot see, smell or taste. Opening a window does not make an outdoor stove safe inside.

At the same time, some cartridge stove manufacturers publish specific ventilation conditions for use in a room, and that detail matters if you are choosing kit. We have unpacked exactly what those manuals say, model by model, in our guide to the best portable gas stoves for indoor use. The short version: default to cooking outside or at a wide-open doorway, keep sessions short, never use a stove for heating, and fit a carbon monoxide alarm certified to BS EN 50291 in any room where fuel ever burns.

What is never negotiable: charcoal barbecues, disposable barbecues and patio heaters stay outside, always, even after they look out. Smouldering charcoal gives off carbon monoxide for hours, and bringing a used barbecue into a house, garage, shed or tent has killed people in the UK.

If you have any sheltered outdoor space, a doorstep, yard, balcony with clearance, or garden, a proper gas camping stove turns a power cut into a minor inconvenience. A two burner stove handles family cooking much like a hob: pasta, fry-ups, curry, boiled kettles for flasks. See our full comparison of the best gas camping stoves for power cuts for models worth owning.

Three options stand out for home standby:

• A double burner cartridge stove such as the Campingaz Camping Kitchen 2, which cooks real meals for a household on removable pan supports. Check price on Amazon
• A fast boil system such as the Jetboil Flash, which boils half a litre in around 100 seconds and sips gas, ideal for refilling flasks all day. Check price on Amazon
• A folding two burner bundle with gas included, such as the Kemper 4600 W folding stove supplied with four 450 g cartridges, so you are not caught with a stove and no fuel. Check price on Amazon

A charcoal barbecue also cooks well outdoors, but it is slow to light, hard to simmer on and carries the carbon monoxide warnings above. Gas is the better standby tool.

Fuel planning is easier than it looks. A typical single burner cartridge stove runs at about 2.2 kW flat out and empties a 220 g butane cartridge in roughly 60 to 80 minutes at full power, noticeably longer at simmer. A 450 g cartridge on one 2 kW burner gives around two and a half to three hours of full-power cooking.

In practice you rarely run full power. Boiling a kettle takes a few minutes, a pan meal perhaps fifteen. A sensible household reserve is four to six 220 g cartridges, or two to three 450 g cartridges, which covers hot meals and drinks for several days. Store cartridges upright, away from sunlight and heat, and never change a cartridge near a flame: do it outside or in a well ventilated spot, exactly as every manufacturer manual instructs.

Match the cartridge to the stove: bistro-style stoves take 220 g to 250 g clip-in or slot-in butane cartridges, while many camping stoves take screw-thread EN417 canisters or valve cartridges such as Campingaz CV470. Check before you buy fuel, they are not interchangeable.

Put together, here is a workable two day plan for a UK family with one gas stove used outdoors and two flasks:

Day one

• Morning: flask-water tea and coffee, overnight oats or cereal with UHT milk.
• Midday: instant soup and noodle pots from flask water, cheese and crackers.
• Evening: one stove session outdoors: a one-pot chilli or pasta, plus a full kettle boiled to refill both flasks for the night.

Day two

• Morning: porridge made in one stove session, kettle boiled again for flasks.
• Midday: tuna bean wraps, fruit, no cooking.
• Evening: curry from tins and pouches in one pan, rice pouches warmed in the same pan.

Two stove sessions a day, each with a kettle boil tacked on, keeps fuel use low and keeps every hot drink off the flame. After dark, do all of this under battery light, not candles: see our guide to the best emergency lights for power cuts, and the wider off-mains heat, cooking and light pillar for how the whole system fits together.
