I need to extend the floored area of my loft. The loft consists of
trusses supporting the roof which is quite a low pitch so you cannot
stand up in it. Previously I attached 3 X 2 cross members to the
trusses 300mm above ceiling height so not to compress the insulation.
I then used loft boards screwed to the cross members to form the
floor. Owing to the variable spacing of the trusses to get the boards
short edges to rest on the cross members meant a lot of measuring and
cutting wasting a lot of material in the process not to mention time.
This time I am thinking of avoiding the cutting so I am thinking of
staggering the boards which will mean most of the short ends will end
up in space and hoping the T&G of the adjacent boards will provide
the support. The flooring is only to provide crawl space whilst I get
some wiring done. Anyone done something similar and does it provide
adequate support for an overweight not so agile OAP to crawl around
and work in?

You could just glue the T&G at the ends of the board.

Alternatively, rather than mess about cutting the boards to length, just
slap a nogging in between any pair of joists where you have an
unsupported end. A bit of 4x2 on its side would give plenty of extra
support to the cut ends even though it would not be full width.
