Two-thirds expect to turn the heating down this winter in energy price squeeze HPI revealed that Labour was the political party most trust to tackle cost of living issues, with more than 50 per cent agreeing that Ministers should freeze prices, following Labour leader Ed Miliband's controversial Election vow. Most will respond to rising bills this winter by wearing more clothing this winter, while others will turn off more lights. Alice Beauchamp, HPI research executive, said: "Across our surveys it appears the 25 to 34 year-olds are the ones that are really being squeezed by the cost of living. People are feeling a little bit more positive about the economy than they have done but energy is a really big issue for them. The report came amid claims 10,000 jobs could go across the country if the Government scraps or scales back the "Eco" programme of free insulation and energy efficiency measures funded through household bills. The UK Green Building Council said any cuts to the green programme would "decimate the very industry that is helpong people reduce their bills in the long term." Separately, Consumer Focus revealed complaints to the Big Six were up 20 per cent on last year - even before this winter's price rises. Npower has seen a five-fold increase in complaints since October, to 190 complaints per 100,000. Audrey Gallacher, director of energy at Consumer Focus, said: "Complaints about npower over recent months put it in bottom place. The company is implementing system changes that inevitably caused disruption to customers, however its complaints performance is unacceptable. Gillian Guy, Citizens Advice chief executive, said: "Price hikes of 36 per cent over the last three years, coupled with poor customer service, has compounded the lack of trust in energy firms as households struggle to afford to have warm home."
