Easy to set up but let's see if I can get my money our in 1yr
Easy to set up a 1 Year Fixed Rate e-Saver 4.41% Maturity.
So it isn't or rather should be complicated.

Well fingers crossed. I'm just having difficulty with Plum ISA that can't be transferred out to OakNorth Bank. Not your problem, my problem, but not of my making.
Of course if providers didn't drop their rates (way below others) there'd be no need for musical chairs and upset. Fingers crossed for a year's time.

We'll contact you a couple of weeks before the maturity date for your instructions, we'd expect that your maturity process will be as equally trouble-free!
ISA transfer from another provider
I transferred a maturing Cash ISA to Castle Trust Bank, once I filled in the details Castle Trust did the rest.
All done hassle free.
