So people in an average house can spend about £100-200 and save about
£10 a year.

That us actually a good return on the investment and so should be done.

I didn't say it wasn't unless the space lost matters. That can be
worth a lot more than £10 a year.

My point was that there are much larger losses of heat.

Take the same house of 7m square and 5m high.

NO! Take a house of 7m square and 5m high and split it in two and calulate
it separtely. Then adding a lot of insulation in the loft makes one half of
the house, the upper floors, very cheap to run and very comfirtable in
winter and summer.
