Scenario
Long Power Outage
Loss of mains electricity for hours or days — from storms, grid strain or faults.
The risk
Without power you lose lighting, heating or cooling, refrigeration, communication and often water pressure. Most outages are short, but multi-day events are increasingly common after severe weather.
☀ Before
- Build a small lighting kit (lanterns, headlamps, spare batteries).
- Keep a power bank topped up for phones.
- Know how to manually open gates/garage and any electric water pump.
- Store water in case mains pressure drops.
- Fit a carbon-monoxide alarm if you might use fuel heating.
⚡ During
- Switch off appliances to avoid surge damage when power returns.
- Keep the fridge/freezer closed; food stays safe ~4h / ~24h respectively.
- Use generators or stoves ONLY outdoors and away from openings.
- Check on neighbours who are elderly or reliant on powered medical gear.
✓ After
- Discard food kept above 4 °C for over 2 hours once cooled.
- Reset clocks and any sensitive electronics.
- Note what ran out fastest and adjust your kit.
