If you have a prepayment meter, from 1 October your prices will be changing. Most customers will see their energy bills come down, but how it affects you will depend on your own circumstances.

What's happening? open/close

How it affects you will depend on your own circumstances, but for most customers:

If you’re on an Economy 7 meter, your day rate will be going up, but your standing charge and night rate will be going down – you’ll receive a letter which will tell you how the prepayment price change affects you.

It means the cost of a typical dual fuel energy bill will be going down by 1.9%, or £21 a year on average. Further information about how is this worked out?

But prices may increase for some customers on Economy 7 due to your day rate going up.

After the price change happens on 1 October, you’ll be charged at the new rates the next time you top up and insert your card or key into your meter.

Why are electricity and gas prices going down?

For most of our customers, gas and electricity prices are going down because of the Prepayment Price Cap, which was put in place on 1 April 2017 and continues until the end of 2020. The Cap is a limit set by Ofgem on the cost of gas and electricity that you’ll pay through your prepayment meter.

Why is the Economy 7 day rate going up?

For some of our prepayment customers, our electricity Economy 7 day rate is going up due to changes made by Ofgem to the way the Prepayment Price Cap is calculated.
