About our Online Price Fix August 2016 tariff

  • Prices are fixed until 31 August 2016 subject to governmental or regulatory requirements.
  • And there’s no exit fee if you decide to switch tariff or supplier.
  • This tariff is available to new or existing customers who pay by fixed monthly or variable quarterly Direct Debit. Unfortunately it’s not available to customers with non-standard or prepayment meters.
  • You’ll need to manage your account online and get your bills and other key communications via email

Please note that if you start using more gas and/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 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.

£1,040 average annual cost, including Direct Debit discounts and VAT at the reduced rate of 5%, based on:

  • a customer with standard single rate meters
  • typical annual average consumption of 3,200kWh electricity and 13,500kWh 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

Annual charges may be higher than our standard charges.

Correct as at 18.05.15.

After 31 August 2016, 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: there’s the amount you pay for the fuel you actually use, and then there’s a standing charge that pays for the cost of delivering and supplying energy to your home, this is irrespective of how much you use. Standing charges vary depending on the tariff you have and there are different standing charges for the supply of gas and electricity.

Direct Debit Discounts 
With Online Price Fix August 2016, you’ll get a continuous discount in a lower daily standing charge when you pay by Direct Debit. The discount is worth £90 over each year if you pay for both electricity and gas by Direct Debit, and comprises a discount of £40 on your electricity charges and £50 on your gas charges. 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: There’s no exit fee if you decide to switch tariff or supplier.

Offer subject to availability and may be withdrawn, suspended or amended at any time.
