Anyone considering changing their utility supplier aught to consider any get out clauses they already have or might be consigning their soul to.
Homecall gave me a fright just now when I opened a letter confirming my leaving. I'm pretty happy enough with their telephone service but as I am not a big phone user, I can get an unbundled BroadBand combination of telphone and landline rental from Talktalk at much better rates.
As it happens the letter was a misdirection, since I don't have an internet service with Homecall. There is no "don't leave early" clause with their telephone service. But it woke me up.
