10 ways to save on energy

1. Lower thermostat by 1°C

Save ~10% on heating = ~£80–100/year

2. Boiler temperature 55–60°C

On combi boilers — save ~4% on gas

3. Wash at 30°C

Uses 40% less electricity than 40–60°C

4. Turn off standby

"Phantom load" can be up to 30% of your bill. Turn off TV, chargers at the socket

5. Insulate windows and doors

Draught strips cost a few pounds at B&Q, the effect is huge

6. LED bulbs

Use 75% less energy. £1–2 per bulb at Lidl/Aldi

7. Do not dry clothes on the radiator

Increases humidity → boiler works more. Dry on a line or a drying rack

8. Close doors

Heat escapes from room to hallway. Closed door = less heating

9. Smart meter

See your usage in real time → you automatically start saving

10. Switch provider

Compare tariffs on Uswitch.com once a year

According to Octopus Energy — you can save ~£271/year by following basic tips.
