Community Energy Direct/Which are organising a collective energy switch to try and get a better deal for gas and electricity. Nearly 5000 people have signed up so far. The deadline for signing up for information (no commitment required) has been extended for 2 weeks.
OK - I know it is the most boring thread title ever, but have a look. It could save you ££ and there is no commitment required. They just give try and find a better price, and then give you the information so that you can decide whether to switch energy provider or not.
