Where should you start?

• If your bill looks unexpectedly high, first check the bill period, meter readings and unit rate.
• If you want to know which appliances matter most, start with the biggest electricity users and then measure your own usage.
• If you are comparing appliances, calculate the running cost using your own tariff rather than relying on a generic saving claim.
• If heating is your main concern, move next to the dedicated Heating guides rather than treating every electricity cost as the same problem.
