Under carpet insulation.

Gareth,
The existing insulation is both for sound-deadening but also uses foam blocks to fill the gap to the floor extrusion to enable the carpet to sit flat. However it can trap water.
If I were changing mine, I would fit some Dynamat foil for sound-deadening and heat insulation and then some closed-cell foam blocks to line the floor gaps then run some thin closed cell foam on the top before the carpet mats.
Good luck
Paul

And before you follow Paul's sage advice, coat the fully dried out floorpan with PoR 15 or RustBullet. The floors rot from the inside out at least a much as from the bottom up. These modern coatings are 100% waterproof if two coats are applied as instructed.
Under the back seat is also an area where the car can rust, so worth doing there too.

I forget to add earlier: spray some wax, preferably preceded by Aquasteel, under the rear seat metal (shown in my pic above). there is a hole or two already there. This protects the rear radius arm and jacking point floor metal (which is under the seat bucket floor) from rusting from the inside out, too.
