Safeway is giving customers the opportunity to shop around for the best deals on gas and electricity through a new link on its web site. Customers type in their postcodes and the amount they currently pay for energy bills and the site calculates the cheapest supplier in the locality and offers customers the chance to switch providers. Safeway claims the link can save householders up to £150 a year. The service has been launched after the Commons Public Accounts Committee found customers could shave an average of 13% off their utility bills by switching suppliers. {{NEWS }}
