Pool of water in drivers footwell

First thing I would do is check / clear bulkhead scuttle drains .

Could check windscreen by applying fairy liquid spray solution to outside and blowing with compressed air from the inside or applying heater blower and see if it bubbles up

Thanks, I’ll try that - if can find them ?

Cant help you on locations on your car , never had to do it on one . Usual places are in corners and water drains out under wheel arch covers on some . Often the bottom where it drains out becomes plugged and can be cleared with a wire or rod . On some makes it entails removing plastic covering / grille at wipers to get access and can be a central drain

Okay I got that, now I know where to look, thanks again I’ll let you know how I got on.
