Offset Mortgage Account alternative to IF

[shindha]

We (me and the wife) have an offset mortgage account with Intelligent Finance (Halifax) we have held this account for about 15 years. They have now made these accounts sort of dormant they will still carry on operating the existing accounts but not open any new ones. They will not allow us to set up any more "jars" within our existing account and not borrow any more funds either.
We would like to know if any one knows of a competitive alternative or experience of an offset account from a different provider. Although we have been quite happy with this account and method of dealing with our finances but are open to new ideas.
