More than a million British Gas customers will benefit from a small fall in their bills as the company implements a plan to reduce prepayment meter charges ahead of time.

From Saturday, prepayment meter customers will pay as much as direct debit customers for gas and keep the same current discount for electricity prepayment meters, British Gas said.

It means the average customer getting both gas and electricity from one of the supplier’s prepayment meters will be £59 better off per year.
