Which concrete blocks?

Unless this is a strict planning condition you may find render is more acceptable to future purchasers and lenders.  Probably cheaper and quicker as well.

The cladding is something we don't want to change.

I have put the numbers into the knauf calc and I end up at 0.19.  The other issue is that I am using timber clad and not render.

 

Change that to medium blocks inside and outside and you get to 0.18. That's a nice calculator actually by Knauf. It is fairly optimistic with the values it's allowing for the airspace behind the plasterboard though but it'll get you through regs which I'm getting the impression is the aim.  

 

 

 

Hemelite blocks are a small bit cheaper too. 

 

 

 

 

 

Superglass is a bit cheaper again than Knauf.  

 

 

 

 

 

£51.37 inc VAT per m2 for the blocks and insulation.
