HUNDREDS, maybe even thousands of npower customers in are missing out on refunds for being overcharged on their gas bills in 2007, said Consumer Focus, a watchdog group urging them to put in claims.

The fuel-supply company has almost �2 million still up for grabs from a �70 million payout chest which will be shared by the remaining 53,000 London customers who have yet to claim.

With payments of up to �100, and an average of �35 plus VAT and interest, the payment could make a big difference to cash-strapped consumers.

In all npower is offering repayments to 1.89 million households nationwide. These customers are likely to have paid for more higher-priced gas units than they expected to in 2007 after the company changed how it charged for these units without telling people.

Christine Farnish, Chair of Consumer Focus, said:

“It is great news that over fifty million pounds has now been put back into the pockets of over a million people nationally by npower. We want to encourage all those consumers still entitled to a refund to get the cash that’s rightfully theirs.”

Anyone else who thinks they may be due a refund should call the npower helpline on 0800 975 7938 to see if they are eligible.’
