SAYE Scheme and transferring to an ISA

Hi There, I'm currently in an employee SAYE scheme expected to mature at around £20k in January. Having contributed £7.2k, with the tax-free allowance of £6k that will be a £6.8k capital gain. We've been told that our options are 1) Sell the shares, 2) Hold the shares, and 3) Transferring the shares to a SIPP or ISA. I want to sell the shares and take the gain in the quickest, most tax-efficient way possible. Is it possible to chose option A to sell the shares immediately and move the cash into a cash ISA and avoid CGT on the £6.8k? Or is the only option for me to transfer the shares to a stocks and shares ISA, and subsequently sell the shares there? If I do transfer them to a stocks and shares ISA, will this take time to process? And does there tend to be a minimum length of time I'd have to hold the shares in the stocks and shares ISA before selling them? I'm yet to open a stocks and shares ISA, so I'd be opening it purely to transfer the shares into it and sell them ASAP. I'm worried the shares would fall in value throughout the transfer to the stocks and shares ISA and the time they would have to remain in it! Thanks a lot for your help, Ryan

Hi RyanStobo,
Please have a look at the guidance at section 3 for SAYE shares for guidance on what happens when you sell the shares or transfer them to an ISA account.
