From a report on BBC Radio 4 Today program this morning, it seems that
(if I heard correctly) some 800,000 homes which were insulated for free
by the energy companies in last 10 years have been done so badly, the
insulation needs to be removed. These are homes which had cavity wall
insulation installed, or external insulation panels installed and
rendered. This also applies to some homes insulated more recently under
the Green Deal scheme, where the owner pays through increased fuel
prices for 20 years.

On one council estate in Preston, Ofgem recently ordered the energy
supplier to pay £1.2M to fix the first 60 homes, and there are
300 more to do.

Another estate paid for by SSE has 250 homes which need rectifying.
At the moment, SSE is pointing to the contractor, but they've gone
bust. The workmanship is apparently terrible.

BRE said they have inspected 2000 homes across the country which had
insulation installed, and none passed.

The BBC interviewed one of the installers. He said they knew there
was no oversight and none of their work would be inspected.

So, we all paid for this through higher fuel prices, and I guess
someone is going to have to pay to undo it all (which is much more
than the installation cost).
