They are trying to push people to heat pumps (basically air conditioners tech wise)

They are also moving towards building/efficiency regs that require completely sealed houses and forced air systems in new builds.

So new houses will effectively be required/encouraged to have an air con capable houses.

The old housing stock though? Oof. I’m on a private estate that even bans that kind of stuff!

Yeh, but it’s public and normally has a decent validity, so you could fetch it once and then use it for years.
