About our Super Fix March 2021 tariff

  • Prices are fixed until 31 March 2021, subject to governmental or regulatory requirements.
  • A £30 per fuel exit fee may be applied before 11 February 2021
  • 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 non-standard or prepayment meters.

£1,130 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 09.01.17.

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 now 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 11 February 2021, an exit fee of £30 fuel may apply.
