No notification from Bank - loan rate changed from fixed to variable

I have a loan with Haven whereby my interest rate was fixed for a period of time and my contract noted that this would end at a point in time. That point has come and passed and Haven have changed the rate to their variable rate - however there was no formal notification to me in writing and the first time I noticed was when the direct debit was presented.

Does anyone know if there a requirement under CPC or Consumer Credit Act for the bank to notify in advance in this instance?

When you took out the loan were you informed as to how long the fixed period would be?

Hi emeralds - yes I was informed as to how long this period would be.
