New price guarantee 2009 is charging 9.8%above current sv rate. As we were on previous price guarantee 2008, this will mean a price rise of C 15% from previous rate. plus 9.8%.

Is this good value or are we better to try for a cap or fixed rate with someone else? I have read that rates are forecast to rise by a further 10% this year.

Prices are forecast to rise, yes, and if I were you, I'd just switch to someone else instead of British Gas!
