Cavity wall insulation on ground floor only??

Personally rather than not do it or pay 1000-1500 for scaffold I would consider filling the cavity from the inside if at all possible, depending on the cost to make good 

Yes we did have a look at that, but there are two tiled bathrooms and a tiled, fitted kitchen to contend with, so it's not really feasible.

Feasible to insulate the ground floor only - Yes. I had just the lower half of my property done quite a while back (under a government scheme).

Isn't your house solid wall construction on the upper floor and cavity ground floor? I think this one is cavity above.

You have a very good memory

I've followed your posts on the insulation and other work you've done on the house with interest, so I've got to know a bit about it's construction.

What about from the loft?

Eps bead injection companies have a specific drilling pattern they must follow to get a proper 'fill'. I doubt they would do it from the top, as they would not know if there were gaps left.

One of the most noticeable benefits of us having cavity insulation installed was the kitchen cupboards (and there contents) were no longer freezing inside. Although we did not have the problem, in an otherwise insulated house, cupboards, which have cold air and no ventilation, are liable to attract mold.

The benefit I noticed most from CWI was not comfort or heating bills but the things in cupboards against external walls no longer felt freezing and smelled of mould.  Worth it for that IMO, especially in bedrooms.

Thats interesting. one of our gable walls has a Krend render, so we did not want to go through it if we could help it. This was one of the solutions they offered. It does mean bringing the hoses through the house, but that wasn't a problem at the time.

It's easier if there's no frames in the wall. Getting a full fill under the windows is the hardest bit.

Just to be clear, this was only for the first floor, the ground needed another, solution, and it was only for the gable end.

They must have been confident about getting a full fill to offer it. Beads do flow around the cavity better than other types. Before a binder was added they used to pour out when you opened up the cavity.
