I need to install some new pipes under a chipboard floor in a bedroom , I know how & where to safely cut into the joists below , but can some one tell me the best way to cut & remove a section of flooring ?

I'd use a circular saw, set the blade to the thickness of the board so
you don't cut any pipes.
check for nails/screws first

Yes, take the section you up need to cut.

How would he know the thickness to set the blade? assuming anyone is daft
enough to cut it whilst its down.

well it's likely to be 12mm or 18mm, start at 12mm maybe ?

how else will he get it up if it's "nailed" down (the OP didn't say) ?
and what if he can't take the whole board up ?

Hence my sarcastic remark to his post i.e is it T&G, is it in sheets, or is
it as a whole?

Yes, take the section you up need to cut.

Not usually practical IME. With T&G boards that run under partition
walls (or are at least locked in by skirtings) cutting out a section is
often the only way to go.

Access panels can be taken out with a trend routabout and the bit
removed then goes into a frame to make a suitable cover for the hole later.

Plunge cut with a circular saw is good for big areas - depth will
usually be 18mm or more. A jigsaw with a cut down blade will also work.

My chipboard flooring has the brand name of CaberFloor. It is 600mm.
wide and 22mm. thick and the surface has a water risistant green
coating on it.

I always screww this stuff down so that it is possible to lift in the
future.

As others have said, set you circular saw to 22mm. depth or the
thickness of your chipboard.

I had to cut an 8 inch chnnel to lay some C/H pipes. When I put the T&G
back it did bow downwards between the joists when I stood on it. To
cure that I screwed a 390mm.strip of 4x2 to the chipboard so that it
fitted between the joists. Alternatively you could make a frame betwwen
the joists for the T&G to sit on, similar to making a ceiling hatch.

Drill a small hole into a joist away from possible problems and measure the
thickness of the board.

find a joist and cut in the enter of it so that when replaced both halves
will rest 1/2 on the joist.

The centre of the joist is where the nails are, usually fixed with nail gun
and very difficult to get out.
