Hello,
Thank you for your reply and the warm welcome.
Yes, you are right we appear to have ended up going through two brokers now in an attempt to avoid the fees associated with the original broker I went with (buildstore). The mortgage would be wit Furness building society, who as far as I am aware don't deal direct with customers for self build mortgages.
We are in East Anglia, so England rather than Scotland, our planning is for a build with around 45% timber cladding and 65% brick/Glass (blockwork construction beneath cladding) , I believe we are somewhat limited by that with mortgage lenders due to this.
P.s. Yes the fees were a bit of a shock although was expecting them to be higher than normal.
