It all happens at the same time because the walls have to be tied together with wall ties, and the insulation has to go in before the wall ties.
makes sense, but i have previoulsy had this same conversation with a builder friend, his view was the block work first then insulation then brick work.
it all ends up being the same anyway, but as a newbie wanted to know whats the easiest ay, thanks for the reply. if anyone has any other tips that'd be great too.

The brickwork should go up first, unless cavity is part filled with boards on the inner skin, the bricks havn't arrived on site or the bricklayers are wearing stetsons.
It's much easier to set out the bond for the frames etc and was always done this way in the past before the arrival of insulation.

As stated.
Full fill - brickwork first.
Partial fill (celotex etc) - blockwork first.
We always build using the full fill method as building the blockwork fist is alien to me.
Either way you will only go as far as the lintels before the 'other' skin needs building.

Whether the insulation fully fills the cavity or only partially fills it.
Let's say you build a wall with a 100mm cavity.
Partial fill involves using say 75mm celotex or similar p.i.r foam board insulation with a 25mm air gap. This insulation board is fitted tight against the internal blockwork (inner face of the cavity) hence the need to build the blockwork first.
Full fill involves using 100 fibreglass cavity batts i.e. dritherm or similar and no need for an air gap, so the brickwork can be built first.
Building the brickwork first is the proper way.
