Thanks again.

I am going to hold out and see what happens, ideally they will cancel and process a full cash refund.

Just to add a bit more experience here - I did click through to the voucher link and, potentially misleadingly depending, the terms and conditions on the link I have been given still state under 'Terms and conditions - Holidays':

'If your holiday includes a non-changeable hotel and/or experience product and you wish to make a date change or apply for a voucher, the value of your original flights will be credited towards this. The amount paid for your original non-changeable hotel and/or experience reservation will be forfeited.'

Which sounds suspiciously like even for BA holiday bookings they would not be giving me a voucher for the full value... So I certainly won't be going for that if that is the case.
