Age UK has warned that pensioners are struggling to heat their homes, but it appears that the charity earns £6million a year promoting expensive energy deals. Energy regulators will investigate claims that Age UK unfairly pushed pensioners into taking out more expensive energy tariffs with E-ON on a rate that was £245 a year more expensive than the cheapest available. Last year, more than 150,000 customers were on the higher rate. In return for promoting the rate E-ON gave Age UK a commission of £10 per customer. The charity ‘strongly rejects’ the interpretation of figures. While it is perfectly legal to accept commissions, the regulator takes a harsh line on any hint that customers have been misled.
