My aim/plan is to be able to save £20k each year (in small deposits each month) into my dealing account so I have enough each April to move into my ISA. 

Do you know if I put away (hypothetically) £15k, it grew to £20k in value could I bed-and-ISA it to avoid any CGT?  

Apologies for all the questions 

Saving regularly into your dealing account is a good habit. As you intend to sell each year the average holding periodless than 12 month. For that time period it wouldn't be the normal advice to buy equity. You might find when you come to sell the £20k you've collected all year isn't.
Depending on what you are buying there might have been purchase costs, there might be sales costs and for less than 12 months invested perhaps cash is worth considering as a place to park your accumulating money? Or premuium bonds if tax interest is a worry, or gilts if you fancy a new learn.
Of course that plan doesn't have £15k grow into £20k over the year. Any growth in the dealing account is subject to tax. ONly once in the ISA is it protected, bed and ISAing doesn;t avoid CGT until all the money is in the ISA

Your dealing account should generate a statement for you, this should detail dividends, you should track your own purchases and sales to keep an eye on capital gains.
