We had Cavity Wall Insulation installed into our 1970's 3 bedroom detached house about 20 years ago. It was a "blown in fibre material" which was injected at numerous points around the outside wall. I have no idea if the work was done effectively......there was no way to review the installation.
I was wondering if there is an agency/company that could investigate the quality of my insulation, with a view to recommending an upgrade (if necessary).
My reasoning behind this is, as this is a large house, I want to maximise the effectiveness of my central heating system, to help reduce my gas running costs. I have an efficient boiler and am running TRV's, and I am running the system as effectively as is humanly possible.
I also have very good loft insulation installed, so it is only really the efficiency of my Cavity Wall Insulation that it the "undefined" element, that I would like to get a handle on.
Anyone got any ideas........Cheers

However presumably they do a survey in order to give your house a rating for such a report. Whether this is purely a visual audit or whether they actually would do an IR thermal test I don't know.
You could therefore consider getting an EPC as if you were going to sell your house.
My current house is too old to have cavity walls so I cannot go that route myself. I have fitted double glazing, I am considering in some places replacing the current very old plaster with insulated plaster board but even the thinnest and even by not using batons and directly 'gluing' to the bricks these may be too thick for an existing property.
