Cheers for that, |Ric|. Would disagree slightly about the shares ISA, obviously you can lose a lot, but do the research and it's likely to outperform a cash ISA
should the market conditions be favourable. Obviously, this is probably not the case at the moment
I thought I might get that reply

. Just simplifying it as in my mind shares aren't a valid savings strategy. Sure you can play with them but you would be a mad man in my eyes to do it with your savings.
Another point that I forgot to mention. There is some talk that having all your money in one ISA gets you more interest due to the compound nature of it. This isn't true. The only advice is put your money in the ISA that has the highest interest rate, have no loyalty to your current bank, and move as often as you can be bothered to keep the top rate.
To demonstrate that it doesn't matter where your money is:
Consider £3000 in ISA 1 in Year 1 @ 6%.
Then £3000 in ISA 2 in Year 2 @ 6%
At the end of year 2:
ISA 1 = 3000 * 1.06 * 1.06 = 3370.80
ISA 2 = 3000 * 1.06 = 3180
Total = 6550.80
Now had I put that money in ISA 1 instead of ISA 2:
ISA 1 = ((3000 * 1.06) + 3000) * 1.06 = 6550.80
I.e. the same! It shouldn't be any great surprise as you are dealing with percentages and 6% of 100 is the same as 6% of 50 plus 6% of 50 but there is a numerical example to prove it.
Thus stick the money where you get the most tax and don't worry about moving it frequently. Follow the largest % interest rate as that is the only thing that matters.
Also, even though interest is paid yearly for some banks when you transfer the ISA they work out how much interest you have up to the point at which you transfer it. Then give it to you. So *very* approximately if you have it in for 9 months you would get 3/4 of the total interest for the year. Then the new account would pay the interest for the last 1/4. No money lost at all.
(This is simplified, if you investigate it thoroughly and know how the interest is compounded over the year you might argue. It is correct, just simplified it so it doesn't scare too much. ISAs are great so don't be scared

)
Of course don't change your ISA more than once a year as that breaks the rules.
Ric.
