Not the Sharpest Moderator in the box
I know how you feel, i live in an 1850s early Victorian terrace ground floor flat. The walls are solid granite and the ceiling is the up neighbours floor, not a lot I can do other than fit better windows. Unfortunately when we did ours about 5 yrs ago all we could get was double glazed but would have preferred triple. We are slowly ripping out the lathe and plaster walls and replacing with frame and plasterboard with dp and insulation as we eventually redecorate each room. We only got GCH around a year ago up until then the only heating was a wood stove in the living room and oil radiators in the bedroom. But you do what you can as you can.
