I have a share on which I have a large mark to market loss but don't want to sell. If I do a Bed and Isa I understand that I crystalise the loss for CGT purposes and then buy back into my ISA to keep the potential upside. Q: I am confused by the £40 charge. My share has a very wide bid/offer spread; do I get to deal on both sides somewhere within the bid/offer spread and pay a £40 facilitation fee, or do I sell at the Bid and buy at the Offer, being hit by the spread, and then pay £40 on top? Since I am providing the market maker with the stocks and removing his market risk by giving a simultaneous buy order I am hoping that it is an all in £40 charge. Is this correct??
