You see it on TV and a google will bring up companies that will tell you, who your cheapest suppliers are and hence you should switch to save money.

I have even had unsolicited phone calls and always told them to go away.

I have never switch suppliers as I think it will only be a couple of pounds difference and competition what it is , those that lose customers will have to reduce their prices to get them back.

However wether this is true or not I haven't a clue

My recent electricty bill was a joke (massive) and its only a guestimate (the real reading is much higher).

Anyone switch and saved real money (more then say £50 a year)
