It seems pretty reasonable to me. Most of your wall area is shared
with the neighbours (assuming it is mid terrace) and if you have good
loft insulation the heat loss would be quite small.

Looking at the heat loss calculations that I did for my house before I
renovated it I got values ranging from 15Kw if I installed no
insulation to 8kw if I installed as much insulation as was feasible.
These included 3.6Kw for air changes. This is for a detached house
about 10M square on 3 floors so it should need a lot more heat than a
terraced house.

Experience has shown that the calculations were pretty accurate.

Thanks, that's encouraging
