Granite is really cold, a bad insulator. You might consider dry lining
with insulating materials.

Thanks for all the advice, the comments about the DPC are interesting.
Granite is an igneous rock which I think means it is water proof, the
mortar is not but as pointed out evaporation from old sandy lime
mortar would probably take care of this. Anyway off to investigate
costs of getting services put in!

Depending on where your granite cottage is, it might be worth getting
it checked for radon during your investigations. Combination of some
small and fairly well defined areas of GB plus granite construction
can be iffy. If it is a problem (unlikely but possible) then measures
to minimise it are a potential additional cost as well as beign a good
reason not to over insulate.
