Spot on floater. There is a two day delay in being able to do anything with the cash as every broker operates on T+2 to actually clear the cash. (Some offer even longer settlement terms but let's not discuss that kettle of fish.....)
This can be confusing cos you can buy shares in the same account within seconds using your sale proceeds as the funds will be credited to your trading balance. This makes sense if you consider your buy trade that you are doing is also on a T+2 settlement date. So you sell and buy on say Monday, but all the cash won't be given and handed back over to the market makers until the Wednesday.
So even if you have a trading account and ISA with the same broker, say ii for example, if you sell shares in the trading account on the Monday you won't be able to move the resultant cash into your ISA account until it is cleared on the Wednesday. The folks at ii can however do a Bed&ISA transaction on your behalf where all of this is done within minutes - so you should only pay dealing charges (£7.95 typically twice) plus the spread between by and sell prices which should be a fraction of 1% at the instant of the transaction.
Ii do this easily. I think X-O can't and have to wait for funds to clear two days later.
My solution was to fund my ISA with spare cash, buy GGP, and then sell a matching quantity of shares from my trading account. Repeat until your £20k annual investment limit is reached.
Have discovered selling GGP is very difficult. Caught myself buying them again yesterday..... Couldn't resist a nice dip. Will be hitting that sell button for sure before the end of the tax year to manage capital gains.
