How much will my next bill be?

Your bill is calculated by adding together the costs for your energy usage plus any relevant taxes or charges.

Calculating your electricity bill

Your electricity bill is made up of four parts:

1. Electricity usage
2. Standing charges
3. Climate Change Levy
4. VAT

Electricity usage

To work out the cost of your usage, you’ll need the 'Present Reading' from your last bill (found under ‘Usage Details’) and also a current meter reading.

If you are on Day/Night rates, you’ll need separate Present Readings and current meter readings for Day and Night.

If you have a night storage heater on a separate meter, you’ll also need individual readings.

To calculate the cost for your usage, use the following formula:

(Current Meter Reading – previous Present Reading) x Unit Rate

You can find your unit rate on your bill.

Standing charges

These are calculated by the number of days in your billing period (usually 30 or 60). You can find your current rate for standing charges on your bill or by looking up your tariff online.

Climate Change Levy

Climate Change Levy (CLL) is an environmental tax placed on businesses.

VAT

VAT is charged on electricity usage, standing charges and Climate Change Levy at 5%.
