It doesn't really matter now as the account is no longer available but I believe it is because if you have a Cash ISA product with one provider it can be classed as a "split ISA" and so you can have multiple accounts but they are all part of the same ISA product.
Again, I thought the rules on ISAs was clear, only 1 new Cash ISA per Tax Year.
That's what was being discussed.
Says Sold Out on the website . Not sure you can apply any more, and I always thought you were only allowed 1 Cash ISA and 1 Share ISA per year, multiple ISAs in the same tax year were not possible. You are better off investing in an ISA from Zopa when they finally launch.
Why stop at six, you could have 80 accounts with £250 to get 4% on the full £20k. How many accounts before it becomes too much hassle?
