Of limited value. On older properties with 230mm solid walls,

A minority of properties.

There is still a very substantial stock in this category.




a very large proportion of total heat produced goes out through the
walls.
There is very little that can reasonably be done about that.

It can certainly be inproved, not least with new wall plasters believe

not. Dry lining can make serious improvements too.

The improvement is not substantial until one starts putting in a
reasonable thickness of insulation. This can be ameliorated to some
extent with materials such as Kingspan, but still involve issues such as
reduction in room size, how to handle window and door reveals without
making a pig's ear and redecorating etc. This is not trivial for most
people.


Building regs however will force all refurbs to take such buildings up
to scratch.

And those issues are no worse than e.g. fitting DG windows, or rewiring.
Not hard, juts need redecorating afterwards.

I probably wouldn't buy a property without a SAP report these days
frankly. And would knock off a lot for a poor rating.
