A few weeks ago I opened a Nationwide Fixed Rate Isa with some money that I had at the time. I knew it was a 1 year fixed rate, so I wouldn't be able to withdraw the money. But I expected to be able to add to it, and have just realised that I can't, because one of the conditions is: "Once you have paid in money to open your account you cannot make any additional payments into the account."
Is this restriction unusual?
It's certainly annoying. As this is a cash ISA, I'm not allowed to open another cash ISA this tax year, so if I want to use more of my ISA allowance I will have to use a Stocks & Shares ISA instead, which I don't currently want to do.
I also can't close the ISA without incurring a penalty charge, and it's not clear to me whether I can transfer it either (I will need to call them about that, to check).
