= no, not a tree or hedge in sight

Or, has the windscreen ever been replaced and so not sealed properly.
= not to my knowledge

Or has there been any crash damage repair on that side and panel seam sealer not been done correctly.
= not to my knowledge

Or a defective door opening seal.
= I’ve had a good look at all of the seals and they all look fine: none missing, squashed, perished, etc.

Or the door's internal sealing, ie from the door frame to the inner panel/window regulator assembly is leaking so water is entering the door and instead of leaving via the lower drain point is filling up the door's internal space and leaking out into the car.
= no dampness or signs of water near the door

Or even the door's lower drain point is blocked, logically there must be some though I've never noticed them or remembered noticing them.
= found the drain point, it’s clear

Edit:- tip, remove the cabin pollen filter and check if it is dry or wet and if there are any traces of water having been in the cabin heater filter area. Always remember while the water has been initially found in the front passenger seat floor area, if the car is parked on a slope, the points of entry for this water could be elsewhere.
= filter is bone dry, no signs of water. Not parked on a slope.

This leakage has not been caused by badly fitted driving school duplicate pedals?
= I don’t think so, all looks ‘proper’. Only 1 extra hole was needed to be drilled for a bolt to fit the dual controls - and more photos attached to show this extra bolt (from the footwell perspective and also the engine bay perspective)

How much coolant did it take to bring the coolant level back up to between MIN and MAX when the engine is cold, ideally buy some G13 spec coolant only to add back in.

After much standing on my head and head scratching I discovered that the drain pipe from the air con had been displaced during the work and was venting into the footwell rather than under the car.
