Your energy supply is an excellent resource from National Citizens Advice Bureau with comprehensive answers to frequently asked energy supply related queries.
Ofgem have produced a guide to comparing and switching energy tariff or supplier when shopping around for a new energy deal, including a list of Ofgem accredited price comparison sites.
Due to the current energy price crisis, it may be best for consumers to stick with their current supplier, as many suppliers are not currently taking on new customers and there may be limited, if any, savings from switching. However, it is always good advice to recommend consumers to ask their current supplier if they are on the cheapest tariff.
Citizens Advice have produced a comparison of energy supplier customer service ratings to help consumers make an informed choice on which supplier to switch to if customer service is important to them.
