In January 1993 we paid something over £300 for cavity wall insulation,
accompanied by the mocking of neighbours (just as they did in January
2005 when installed solar water heating). They said it wouldn't make any
difference to anyone except the company which did it.

Was it a new house then?

It was built in 1937.

I had cavity wall insulation in 1980.
Being a physicist I was able to work out how much it would save me in gas
whatever the neighbors said.

I would have been able to do it but I didn't think it was worth the effort.

I do not have solar heating, nor will I unless I DIY it as it doesn't make
economic sense and it won't help global warming either.

It's made economic sense to us.

Must be good if it saves you more than you were paying for hot water in
the first place

Have you got one of those machines that turns blank paper into £20 notes
as well ?
