Is there anything i can do, aside from the large task of installing
reflective plaster board on the chimney - re-platering - getting fire
re-fitted, etc. Is there any special paint i can put on, as a sort of
undercoat to keep the heat in the chimney??

No, no special paint will stop your chimney from getting hot. Insulation
is really the only way to reduce the amount of heat getting through.
