I'm in the UK and it's famously bad due to the age of the housing (lots of it predates WWII or was built cheaply just after WWII). Multiple successive governments have started grants to share the cost of insulation, however these come with onerous paperwork requirements, complex financing schemes, accreditation schemes for contractors, and then are cancelled 18-24 months in due to low takeup. It's gotten to the point where the small companies that provide these services don't even try to join the schemes because they know it won't work out.
