    Do you have suspended wooden floors (floorboards on joists) or concrete. If Yes - is the void big enough for someone to get under and insulate, and also to seal the gaps between the floorboards and the walls usually hidden by skirting boards. In many houses you would need care doing this to ensue gas fires etc got enough air - but in an all electric house it's not a problem. Doing this would considerable reduce heat loss.

    For heating I would look to air sourced heat pumps powered of photo-voltaic solar panels during the day and economy 7 at night as the heat source, but then you have to get the heat into the house. The nice thing about heat pumps is you get something like 4Kw heat for each KW you put in - but efficiency decreases as the temperature differential (out/in) increases.

    If it was a new build - you'd probably be looking at underfloor heating using piped warm water, as it's not you could use radiators (which would need hotter water) or maybe a ducted warm air system which might be OK to fit if you have suspended wooden floors, especially with good space underneath.

    You could use water filled radiators, maybe double the size for heat pump heat source compared gas. Or just go for gas.
