[holding answer 9 December 2008]: The Department does not carry out separate analysis to quantify the effect of rising energy prices on domestic coal users. However, in 2006, around 101,000 households in England that relied on coal and other solid fuel as their primary source for central heating were fuel poor, around 46 per cent. of all such households. This is a slight increase from 45 per cent. of all households reliant on solid fuel central heating in 2005 (or 106,000 households).
