I would go further and say that a lot of social housing needs to be torn down and built to a much better spec.

So much was built in the late 60’s and 70’s, it was built poorly by the standards of the day as they didn’t expect it to last as long as they have. They have not been maintained to the levels required, and you cannot just “insulate them” because they don’t have the correct design to handle what is required.

On the other hand you’ll have people complaining about “breaking up communities” if we did earmark a bunch of money to move people and rebuild to modern standards, so it’s a lose lose situation.

There is a reason why people in Britain seem to think that damp is a normal thing in houses, whilst everyone else doesn’t.
