I opted out of the offer to go on this tarriff and had a look around at what else was on offer but before that I did a comparison between what I had paid on the price protection 2010 fixed rate deal in the previous 12 months and what I would be paying on PP2012.
Using 14235 kwh consumption on PP2010 I had paid £990 for the year and for the same consumption on PP2012, I would have had to pay a staggering £1506, an increase of £516.
As I said, I'd opted out and I'm now on their BG's standard tariff but not for long, as I've switched to OVO's one year fixed rate which when using last year's consumption figure of 14235 kwh, gives a cost of £1154 which is a saving of £350 on BG's PP2012 tariff.
I'm well pleased that I fixed with BG 5 years ago but it looks as though they are trying to claw those savings back through their "limited" offer of PP2012 to their old PP2010 customers.
I hope that the rest of the ex PP2010 customers see through BG's little ploy!
