  • You can manage your account online and receive bills and key communications via email. It’s so convenient via our app.
  • Available to new and existing npower customers who pay by fixed monthly or variable quarterly Direct Debit, or Receipt of bill. Unfortunately it’s not available to customers with non-standard or prepayment meters.
  • There may be an early exit fee of £30 per fuel if you change tariff or supplier before 11 February 2021. But with a rate this super, why move?

Please note that if you start using more gas or electricity, then the amount you pay us will increase even though the price per unit remains the same.

Your prices may increase if you change your meter type or the way you pay, or you no longer meet our eligibility criteria for this tariff.

If there’s a change in the rate of VAT chargeable for the energy we supply, this could also increase the charges you pay.

Average Costs

£877 average annual cost, including Direct Debit discounts and VAT at the reduced rate of 5%, and based on:

  • a customer with standard single rate meters
  • typical annual average consumption of 3,100kWh electricity and 12,500kWh gas
  • payment by Direct Debit
  • costs averaged across mainland UK

Your actual annual cost will vary depending on:

  • whether you get both your electricity and gas from us, or just a single fuel
  • whether discounts apply
  • your region
  • your consumption
  • your meter type
  • your payment type

Annual charges may be higher than our standard charges.

Correct as at 23/12/16

After 31 March 2021, you’ll automatically move to our cheapest Standard variable tariff applicable to you.

Standing Charges

We split the amount you pay us into two parts – the amount you pay for the energy you actually use, and also a standing charge for the cost of delivering and supplying energy to your home. You’ll pay a standing charge no matter how much you use. Standing charges vary depending on your tariff – and are different for gas compared to electricity.

Direct Debit Discount

You could save an extra £90 a year on your daily standing charge if you pay for both your gas and electricity by Direct Debit. That’s £40 off your electricity and £50 off your gas. Subject to change.

Meter Readings and Tariff Changes

We’ll use your own meter readings to create your bills whenever we can. If we can’t, then we’ll estimate how much energy you’ve used, using industry standard information. Please note that our agents still need access to your meter to take readings sometimes and to carry out important safety checks.

Changing your tariff or supplier

There’s an early exit fee of £30 per fuel if you change tariff or supplier before 11 February 2021. But with a rate this super, why move?
Offer subject to availability and may be withdrawn, suspended or amended at any time.
