We are going through this at present.
Today we got a letter from Energy helpline, who are part of Ofgem, and every year they write to us having done the comparison work for us.
We are with Eon at present, but it is reckoned we can save over £30 per month by switching.
The “best” offer from a Big Six comapny is EDF, but a smart meter is mandatory. Too many reasons not to have a smart meter, and few reasons to have one – namely it won’t save any money, just make it easier for the companies to vary the tariff as and when it suits them!
Going to Green Network is next best and will save us £348 per year. Staying with Eon will see a price rise of £469 per year. Something has to be done.

Other companies suggested include Lumo, Avro, Toto????
Seems like the big boys give a cheap deal this year and ramp it up in 12 months time. We switch regularly.
