About our Go Green Energy Fix November 2021 tariff

  • We will match all of the electricity and gas you use by purchasing the equivalent volumes of renewable energy certificates. Are there environmental benefits?
  • Plus, once you’ve been using gas or electricity on this tariff for over 90 days, we’ll work with Trees for Cities to plant a tree in the UK to help bring environmental benefits to local communities
  • Prices are fixed until 30 November 2021, subject to governmental or regulatory requirements
  • A £30 per fuel early exit fee may be applied before 12 October 2021
  • You’ll already have or, if eligible, agree to have Smart meter(s) installed at your property.
  • This tariff is available to customers with standard credit or Economy 7 credit meters. A restricted credit meter version of the tariff is also available via npower or npower Select.
  • This tariff is available to new or existing customers who pay by fixed monthly or variable quarterly Direct Debit, or Receipt of bill. Unfortunately it’s not available to customers with prepayment meters
  • You’ll need to manage your account online and get your bills and other key communications via email.
  • We regularly estimate how much energy we think you’re using, it helps us to make sure we purchase enough certificates to cover what you’ve used.
  • Information on how we source our fuels and our approach to sustainability, including government support for renewable energy and how your energy is distributed.

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.

£1,138 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 12,000kWh 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 07.11.19.

After 30 November 2021, you’ll automatically move to our cheapest Standard variable tariff applicable to you or another applicable tariff. We’ll let you know at the time.

Smart Meter Installation
You'll already have or, if eligible, agree to have a Smart meter installed at your property for gas and/or electricity (as applicable) within 4 months of signing up for the tariff (or within 4 months of becoming eligible if you’re not already).

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 what they are for electricity.

Direct Debit Discounts
We’ll reduce your daily standing charge if you pay by Direct Debit. So over a year you’ll get £40 off your electricity and £50 off your gas. Subject to change.

Meter readings
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: If you decide you want to switch tariff or supplier before 12 October 2021, an exit fee of £30 per fuel may apply.

Offer subject to availability and may be withdrawn, suspended or amended at any time.
