The batons currently down are about 45x55mm with a foam base
(presumably for soundproofing). They are not screwed into the concrete.

As the room was two rooms before (lounge and kitchen), the batons run
different ways in each. I'm going to replace them all.

why?

Questions before I purchase new batons:

1. I presume it is a good idea to cover the whole sub-floor with batons
before laying any hardwood.
2. What dimensions are best? Is the 45x55 that I have a standard?

thats fine, use what gives you the right height. Such as what youve
already got.

Is
it easy / worthwhile to get hold of with the foam attached? If it's not
easy, should I look to apply foam myself?

yes, the fairies wont do it, theyre on long term foaming strike.
Seriously, yes it deadens sound transmission.

Any other soundproofing tips
(it's a flat so don't want to annoy downstairs)?
3. Any recommended suppliers?

of wood??


4. How far apart should they be?
5. Plan to get them square is to measure points from a wall. Is this as
easy as it seems?

why bother getting them square?


6. Should they be screwed into the concrete? Pros/cons?

no, this will defeat the soundproofing foam.

7. Anything else that I might not be aware of?

why replace them? sounds like youve got what you need already, although
you will want to re-lay one set to get it in the right direction.

But can I purchase battens with the foam already attached?

no idea. youve got them already anyway


3. Any recommended suppliers?

Yes. In London / SE.

yellow pages. Just inspect the wood before paying, and make sure warp
and twist are minimal. BTW you can use wood thats warped on one
direction, sideways, without it causing trouble.

5. Plan to get them square is to measure points from a wall. Is this as
easy as it seems?

why bother getting them square?

I assumed that having them square would lead to my floorboards being square.

no.

7. Anything else that I might not be aware of?

Fair point.

one more point: if you leave both battens and chip down, you could put
a thinner layer of hardwood onto the chip. Half the price, half the
work.
