I've had a google & looked at the FAQ but can't find a deal..
I am under orders to put up 3 wall units today, these will go on the
outside wall which is done in those lightweight blocks that aren't
breeze blocks.
Standard Rawplugs just spin in these due to the crumbly nature of
them.
I fear Rawbolts will just crumble the blocks when they expand.
Screwfix or B&Q are my only options.

Thanks
