The document below sets out the level of the safeguard tariff (or ‘price cap’), which will apply for the period 1 April 2018 to 30 September 2018. We have also provided two spreadsheets which show, for the restricted charging period, how we have:
- calculated the network charge component of the cap
- used the network charge and other inputs to get the final level of the cap
These spreadsheets are updated versions of the illustrative price cap model and network cost calculations spreadsheet previously published by the CMA.
The levels of the cap are expressed in pounds, excluding VAT. They are described for two levels of consumption for a customer that:
- does not use any energy
- uses an assumed amount of energy ‘m’
We get the level of the cap for all other possible consumption levels using these two values. Note that the levels of consumption ‘m’ are not the same as the current typical domestic consumption values, which are commonly used to calculate a typical annual bill.
