Overview
- On July 10 appliance experts urged consumers to temporarily lower fridge thermostats toward about 2°C to give units extra cooling capacity during the heatwave.
- Higher ambient temperatures and warm air entering when doors are opened make internal fridge temperatures rise faster, increasing the risk that perishable food will spoil.
- Public guidance sets safe fridge ranges at roughly 0–5°C, with the U.K. Food Standards Agency advising 3–5°C, and experts recommend using a fridge thermometer to confirm actual internal temperature.
- Practical steps to help fridges cope include keeping the door shut, avoiding overcrowding to allow airflow, letting hot food cool before storing, and organising shelves for quick access.
- Household effects may include more food waste and pressure on storage: surveys cited in coverage show many people do not change fridge habits in heat, and some may consider buying a second small fridge for drinks and snacks.
