CGT on transferring money from an investment bank to another personal account?

We have a pension lump sum invested in a triple access joint account in an investment bank and wish to transfer some of those savings to another of our accounts to pay in stages for a home improvement project. Are we liable to CGT at any stage either if we a) transfer the lump sum to a building society account (not an ISA) or b) pay the builders directly from the triple access account?

Hi Treasuresmith1,
No, as you have not sold an asset.
Thank you.
