When boiling water, heat only the amount of water you need in the kettle and always keep the lid on a saucepan.
The optimum temperature for a fridge is 3°C to 5°C, a freezer works best at minus 18°C. Both appliances function more efficiently if they are kept full and regularly defrosted.


Buying electrical appliances with a higher energy efficiency rating (A is most efficient, G is least efficient) may cost more at first but will save you energy and money on bills in the long run.
