Five practical energy-saving tips for Northern Ireland households before comparing electricity tariffs or switching supplier.
Reducing electricity use can lower bills before switching supplier. These simple actions help households cut waste and compare tariffs more accurately.
1. Turn off standby devices
TVs, consoles, speakers, chargers, and office equipment can continue using electricity when left on standby.
2. Use appliances efficiently
Run washing machines and dishwashers with full loads where practical, and use lower-temperature settings when suitable.
3. Switch to efficient lighting
LED bulbs use less electricity than older bulbs and are useful in rooms where lights are used regularly.
4. Track your electricity use
Use meter readings or supplier account data to understand how much electricity your household uses over a year.
5. Compare tariffs using annual kWh
After reducing waste, compare tariffs using annual usage rather than only looking at monthly direct debit amounts.
Once you have reduced waste, compare tariffs using annual usage on the Wee Switch tariff comparison tool.
