Has anyone DIY'ed external insulation ? The cost was far too high
when I got a quote.

I have dabbled with the numbers and looked at some options for cladding.
I was considering battening over the insulation, then weather boarding
in either real wood, or a modern composite cement fibre board. I found
that the insulation itself can be quite cheap, and even the cladding not
too bad, but its often the sundry extras that add up; such as all the
trim parts for corners and window reveals.

They always say the thin coat / resin render is a specialist
treatment. I was looking for some DIY cladding system to do my gable
wall, which has no windows at all (it faces an entry) - a system that
was approved for building regs of course. I did not find anything -
was a few years ago.

ISTR the main requirement for building regs when making a substantial
change to a thermal element was to achieve a certain U value, which was
not particularly onerous.
