Northern Ireland electricity guide
Decoding Your Northern Ireland Electricity Bill
Published on 28 May 2026 by Wee Switch NI Team. Last reviewed 16 June 2026.
Understand your Northern Ireland electricity bill, including unit rates, standing charges, VAT, payment method, meter readings, and annual usage.
Your electricity bill contains the information needed to compare tariffs properly. The most important figures are your unit rate, standing charge, payment method, and annual usage.
Unit rate
The unit rate is the price paid for each kilowatt hour of electricity used. It is usually shown as pence per kWh.
Standing charge
The standing charge is a daily fixed cost. Some tariffs may show no standing charge, while others include a daily charge that affects the annual total.
Annual usage
Annual kWh usage gives a better comparison than monthly spend because bills can vary by season, household size, and payment method.
Payment method
Keypad, direct debit, standard credit, and online billing tariffs can have different rates. Compare against the payment method you actually use.
Before switching
Check whether exit fees, discounts, loyalty credits, or welcome incentives apply before confirming a switch with the supplier.
Use the unit rate, standing charge, and annual kWh from your bill when checking tariffs on the NI electricity comparison page.
