Cheers Wayne...thanks for your comment!
Hang on you have 3m2 of floor and you are going to put no more stuff on it, that will give you at least 4 points of weakness over 18mm chipboard. You will need to cross the joints on the chipboard which makes this no more stuff idea more expensive as you will be looking at 4+ boards.
Forget £30 if your going to do it right m8
And this no more stuff doesnt reflect heat

Well no thats not what I've said.
You have a 3m2 floor inorder to do the no more stuff right you will need to cross the joints on the existing weyroc boards, to do this you will need minimum 4 no more stuff. If you use 4+ no more stuff then you will have at least 4 points of weakness (where the boards join they hinge)
If you go buy 1 sheet of 6mm ply cost £10 anput it down then you have no points of weaknes and a surface which to work off. Screw down the existing weyroc then screw the ply or use twist shanks to nail it every 150mm.
Because your floor is only 3m your delection is minimal and the above would be fine.

I will explain overboarding of weyroc :
Weyroc (chipboars) is generally used as flooring in modern homes, the boards used are 2.4m long x 600mm wide. They are laid accross the joists and should be glued along the joists and edges.
Bare in mind that propper glueing is rare, the manufacturers say the glue stops squeeking but to squeek the have to move right
In time it is rare to find a floor that has not moved with settlement and the boards often exhibit deflection. Some floors I have seen have been layed with the joists and this creates high spots.
If your intention is to over board either with a substrate board or ply your aim is to reduce weak spots in the floor and prevent deflection. To do this you have to secure points of weaknes or the joints between the boards.
Overboarding should cross the existing joints and be screwed or fastened with ring/skew nails every 100-150mm
Because of the sizes of substrate boards then the more you use the more points of weakness or joints you will have, to help prevent this boards should be staggered (like brickwork).
This can be done with ply but obviously to a lesser extent due to size.
Personally in a room up to 5/6m2 ply is the answer, not only cheaper but makes for a stronger job.
Hope this helps out

Yes Rob !

This is exactly my point and why I generally use ply for these smaller jobs, a floor may be 6m2 but you may only cover 4m2. Substrate boards are cool and have a place but I dont think the smaller job is worth the agro.
All tradesmen have their own thoughts and opinions the above feedback from myself is mine.
