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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what proportion of Warm Home Discount recipients whose energy is supplied by (a) British Gas, (b) EDF, (c) EON, (d) nPower, (e) Scottish Power, (e) SSE and (f) all six firms are on their supplier's standard variable tariff.

Ofgem collect data on the number of Warm Home Discount recipients; the Department for Business, Energy and Industrial Strategy collect data from the energy companies on the type of tariff that their customers are on. These two data sources cannot be combined, and for this reason it is not possible to provide the proportion of Warm home Discount recipients that are on their supplier’s standard variable tariff.

The total number of customers that received the Warm Home discount in 2015/16 was 1,350,403 within the core group as well as further 836,201 to those eligible under the broad group. This data is published by Ofgem in their Annual report online (https://www.ofgem.gov.uk/system/files/docs/2016/11/whd_annual_report_sy5_final_for_publication_0.pdf). The number given by each of the companies listed is given below. Please note, this will not sum to the total number of rebates as the whole scheme includes small suppliers as well:

The proportion of customers on standard tariffs is collected by BEIS in confidence and as such specific company data cannot be provided. Of all domestic customers, in quarter 2 2016, 69 per cent of standard electricity and 67 per cent of gas customers were on variable tariffs. These figures are published as part of our Quarterly Energy Prices publication and can be found in Tables 2.4.2 and 2.5.2 (https://www.gov.uk/government/statistical-data-sets/annual-domestic-energy-price-statistics).
