Read this elsewhere and - ouch:
The book deals were negotiated and signed in April 2020, before the charity was even set up. It appears Hannah and Colin immediately set up a private company to cash-in.
Penguin random house ultimately gave them £1.47m as an advance. First we've heard of this amount that I can recall, I don't think it's been made public and PRH only provided that figure when compelled. PRH offered to donate this directly to the NHS Together fundraising effort (still ongoing at that time) "but that offer was rejected". PRH didn't know who they were dealing with and blithely assumed Hannah and Colin were in it for the charity work.
Instead, the pair asked for the money to be paid to themselves directly so they could set up their own charity. Details become hazy here because they (intentionally?) documented fuck all, but basically everyone was under the impression H&C would get a personal cheque for £1.47m then use (some? Most? All of?) the proceeds to start the charity that would become the captain Tom foundation.
If you've read the charity's financial books as I have, you'll know no such payment ever came. In fact the charity commission wrote to them, twice, last year before they went on piers morgan's thing, presented the evidence they'd gathered, and offered them a chance to make a donation to clear it all up. They refused both times and kept the money. They forgot to mention this amount to piers who will no doubt be upset.
With the £800k in sales (also directed to club nook) I make that £2.3m they've profited off the books without the charity seeing a penny.
