best to use engineering bricks to dpc or concrete blocks to dpc for block shed?

is it best to still use engineering bricks up to dpc from foundation footings or concrete blocks to dpc? Shed is a block shed single skin. I have no clue what BS standard my blocks are rated to as the pallet had no labels it was simply a pallet of 90 for 1.20 each block though they are heavy so I assume standard 7.3n blocks. My original idea was lay the blocks flat on top of the concrete footings and then upright up to dpc but looking at mixed thoughts online I am wondering if its best to stick to engineering bricks to dpc and then block from there on?

 

So lay the initial flat then upright up to dpc level which I think should work ok for dpc height wise.
