I plan on laying T&G, 22mm, P5 chipboard flooring soon and would like to know what type and size screws should be used. I have looked through the forum and some people recommend 2.5 or 3 times the thickness of the chipboard for length. Some people recommend no. 8 or no. 10 screws, but Screwfix only seem to supply up to no.6 size screws.

I don't know where you get the idea that Screwfix only supply up to no.6 screws. I hope you realise that no.6 is not the same as a 6mm metric screw. Also you don't need chipboard screws, these have a thread suitable for securing to chipboard, whereas you are screwing through chipboard into joists.

I too would use no.8 or 4mm screws. Personally I would use Quicksilver screws but that is only because I have a huge stock of them and don't usually stock metric screws.
