O/T Energy Prices...

Have received my latest statement from npower & they are increasing my monthly direct debit for combined gas/electric to £254 pr month (from 01.11.09)!! This is from £151. As of 25.09.09 I was £134 in debit & they get another £151 tomorrow - so I'll be more or less even with them.
I live in a standard semi with GCH that goes on for 2hrs in the morning & 3hrs in the evening & it got it's first airing since April only last week.
Are these charges normal/excessive & is it time to 'Uswitch.com'?
Consumer advice always seems constructive on SV so any help will be gratefully received.
