On the basis that 1l oil = 10kWh and 1cu m wood = 2500kWh, the total is between 25+10=35 and 40+10=50 MWh per annum.  That's definitely in the same general ball park (dividing by 2000-2900 depending on which calculation you prefer) so I would say that the heat loss calculations are at least plausible.  So basically I'm with @bontwoody

Id be tempted to consider something like a 16kW heat pump (or the largest reasonable one you can find, avoiding anything too extreme) with some backup heating for the coldest days if it turns out you need it!  Or an 8 and a 10 kW or similar running either alone or together.

4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.

@abernyte thanks tbh I was more thinking about bolstering the insulation within the timber frame which would entail removal of plasterboard etc.  and a massive amount of disruption.
