Looking at the wet patch by the front wheel could there be water in the heater plenum where the drain holes are? It looks like the water is draining out but perhaps after the heavy rain it didn't drain quickly enough and lipped over, through the heater matrix and into the footwell.

[Philno]

Thanks Jocko

You certainly have more technical knowledge than me regarding autos !

Is the heater plenium underneath the black plastic grilled strip from which the windscreen wiper bottoms go through, directly below bottom of windscreen?

[Jocko]

Yes. With the holes in the top to let the fresh air in. Sometimes at this time of the year, it can get choked with leaf debris.

[Philno]

Thanks to all with your suggestions.
Based on the info from Glosrich and Jocko, 
I am going to book the car in with my local
car repair business for it to be looked at next week hopefully.
I will ask them to particularly look at the windscreen for any bad seals and under the plastic grill which covers the drain holes and heater plenum area for any blockages. The heater and Aircon appear to be working OK.
I will let this forum know how I get on so it may help others in the future.
I am going to put the wet/dry vac on the still very damp area of the footwell. I have been using newspaper and towels to soak up water from the underfelt below and there is still quite a bit of water under there as the towels are still very wet when I change them. I've not tried to  take the carpet up, only removed the car mat, so there may be still a slow seepage going in.

We shall see!

The pollen filter is behind the glovebox, so that suggests the heater inlet would also be passenger side above it, into the plenum at the base of the windscreen.

I would get the pollen filter out and see if it's wet.

Can you remove cover over the pillar and have a look in there.

It is the drivers side you said, some answers here seem to refer to passenger side.

You may have missed my replies (see reply #29) that I have checked the pollen filter behind the glove box. I took it out and it was dry as a bone and clean as I put a new one in this Spring.

I am booking in the car with a garage. I am not a car enthusiast and I am more safer getting someone with the better skills to look at it further as December is not a good time to take car to bits!  If it was summer I might have had a go taking off the pillar trim, but I'd sooner pay than risk things!

Any news yet has it been solved

Hi Bigfellah

I've not yet resolved this yet, but I intend to have the vehicle checked out by my local Honda approved car repairer after Xmas.
Despite recent rain there has not been any further noticeable water ingress in the driver's floorpan. Since I used the wet dry hoover to suck up the wet area last week, the area has got progressively dryer. I still intend to have it looked at soon though as I don't want rust or any electrical problems as the damp area is not far below the cabin fuse box area and presumably the ECU .
I'm still monitoring it daily.
I think the water came over/through the firewall from the windscreen cowl due to a blockage. Also the seal between the bottom of the windscreen and the engine cowl looks a bit dodgy to me as there is a small gap along the centre quarter of its length of approx 3mm which could swallow up water. I think heat from the hot sun this summer could have distorted the black plastic causing misalignment. I temporarily covered this with black electrical tape.

So we shall see

They got a taste for snorting dry white powder while searching for damp.  They should have used talcum powder

Just an update after nearly 4 months. The water ingress in the driver's foot well has not reoccurred since the original event in November. This is after a very wet winter.
I held back taking the car in for inspection like I said I was going to do.
I had the car serviced and MOT'd last month with no problems.
 A  couple of weeks ago we had torrential rain which caused the abandonment of my local Championship football team's fixture early in the second half. The car survived it!
My friend suggested that the original leak could have been caused by a temporary blockage due to Autumn debris building up below the windscreen. So far so good, but I will still keep monitoring it just in case.....!

Very good news.
