Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, whether an estimate has been made of the number of energy customers in Berwickshire, Roxburgh and Selkirk constituency who are on (a) standard variable tariffs or (b) a default tariff.

The Department collects data from energy companies by public electricity supplier (PES) regions; data is not available by parliamentary constituency. In South Scotland, 64% of gas and electricity customers are estimated to be on variable tariffs.

The Department’s methodology to produce estimates of customers on fixed tariffs is reliant on this being explicitly detailed in the tariff name so may not completely identify all tariffs. All tariffs not identified as fixed are assumed to be variable; however, standard variable tariffs cannot be distinguished within these.

Data are published in Quarterly Energy Prices tables 2.4.2 and 2.5.2.
