Here you can view the set price cap levels suppliers must apply to their default energy tariffs, including standard variable tariffs.

The main document lists the default tariff cap levels that will apply for the charge restriction period 1 January to 31 March 2019. The cap levels are expressed in pounds, excluding VAT.

The subsidiary document gives worked examples for suppliers on how to apply the caps to their default tariffs, alongside responses to common questions on how to read the default tariff cap level tables.

The default tariff cap limits the maximum standing charge and price per unit (kWh) a customer on a default tariff can be charged based on the underlying costs to serve energy. It does not cap a total bill, which will vary depending on how much energy is used.

Different cap levels apply depending on a default tariff customer’s:

  • Location
  • Meter type
  • Payment method (standard credit or direct debit).

The levels of the cap cover two levels of consumption:

  • ‘nil kWh’ – for a customer that doesn’t use any energy
  • ‘m’ – for a customer that uses an assumed amount of energy (‘m’ is the same as typical domestic consumption values, which are commonly used to calculate an average annual bill).
