British households on prepayment meters risk missing £130m of energy bills support

Low redemption rate for vouchers sent to prepay customers by post or email under government scheme

British households on prepayment meters face missing out on up to 130m of support for their energy bills if they fail to redeem government vouchers before they expire in a month's time.

Under the energy bills support scheme, which runs until 30 June, all households are entitled to discounts of up to 400 on their bills.
