My current contract with EDF ends 31/8. I've compared my usage on Uswitch and decided to stick with EDF. The problem is that they have four tariffs. The Martin Lewis website predicts gas prices will go up soon, but then come down in October next year. Doesn't say why, but maybe new gas fields coming on? So I could go for a one-year fixed, but it's the most expensive! The others are two-year fixed, or tracked (currently the cheapest, goes up & down), or standard. WWYD?
