How are prices calculated?

Ofgem publish maximum annual bill values for customers. There are different capped levels for different areas, meter types and payment methods.

This is known as the default tariff price cap.

These bill values are used to create prices (unit rates & standing charges) which over the course of a year would result in a customer paying the maximum annual bill value permitted by the default tariff price cap.

With Cap Tracker December 2020, you’ll then get a discount of 6% on these prices

Further information around the Ofgem Default tariff cap can be found at https://www.ofgem.gov.uk/energy-price-caps/consumers.

Correct as of 01/04/19

After 31 December 2020, 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.

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 and unit rates for paying by Direct Debit. How much of a discount you get will depend on how much energy you use.

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 November 2020, an exit fee of £30 per fuel may apply.
