So I priced it up for my house, 2 ways:

Method 1:

25mm Jabfloor 70 overlaid with 18mm water resistant T+G flooring chipboard
as recommended by Jabfloor's data sheet = (for 95m2 ish, whole ground
floor) £731 inc VAT.

Same with 25mm TB3000 Celotex and 18mm chipboard = £888

Seems to be another option. Nothing rottable there AFAICS and everything's
glued to everything to no voids for water to collect.

Twice the price though (around 2k). But half the work to lay. Anyone know
anything about these "insulation backer boards"? They're new to me...

Living in a house with uninsulated solid concrete floors (on the ground
floor!), I would very much appreciate anything that would allow
insulation. The 6mm might just about be usable.

My own highly sensitive thermal detectors[1] show a difference between
warm and FF when stepping down from bottom stair to floor. So I strongly
concur that doing something is highly desirable.

Although I only looked quite quickly - I couldn't see the area of the
tile-backer boards! Is that per square metre or a 2.4x1.2 or what?

[1] - Slightly less noticeable with fluffy slippers on them.
