Can i use hollow block on strip foundations to build my dwarf walls?
Roof is Poly so little weight and i intend to use a kingspan board between internal face and the plasterboard. Externally will be UPVC clad.

A light conservatory may be considered to equate to a ships sail.
It needs to be firmly fixed in place, to stop the wind from sucking it into the air and dropping it down the street.
If the blocks do not provide a safe anchorage, you may well loose it.
You could fill the blocks with concrete.
Do make sure you know what you are doing, before you have an accident, it may land on your home.
