Question
To ask the Secretary of State for Energy and Climate Change, what proportion of households are with their home, regional incumbent, supplier for electricity and gas in each electricity supply region.
DECC estimate the regional market share of the incumbent supplier compared to the rest of the Big Six. These are published by Public Electricity Supply (PES) region in tables 2.4.1 and 2.5.1 of Quarterly Energy Prices.

Smaller suppliers now account for around 10 per cent of the domestic market, so the above figures overstate the proportion of households with their home supplier. DECC do not have a regional break down of data for these small suppliers.
