Start with the big users
High-wattage appliances used for long periods — heaters, tumble dryers, electric showers and ovens — usually make the biggest difference.
Simple changes
- Wash clothes at 30°C and dry them outside when possible.
- Shorten showers.
- Boil only the water you need.
- Switch devices off rather than leaving them on standby.
- Use timers and thermostats on heaters.
Measure before and after
Use the appliance calculator to estimate a change before you make it, and your smart meter or bill to check the result.
