I have just received a letter from Scottish Power informing me of the new prices from the 1st of October. According to them the new tariffs will cost me an extra £62 for gas and £22 for electricity. That's a total rise of just under 18%!!!
Then you get to the small print on the back page an lo-and-behold if I switch to their current cheapest tariff I can get a total saving of £59 based on my current usage - a £143 difference between the two. The £59 saving will probably be wiped out by price rises before October but at least I will be no worse off!
And once I change I can then hunt around for cheaper deals with other utilities. I am on to it.
