> The UK typically doesn't need air conditioning

I don't know where you live but UK summers were unbearable even when I was a kid. Buildings are engineered to trap heat, so the heat doesn't dissipate at night and every day the indoor temperature rises, and rises...

At least they removed the need for planning permission recently. The problem is that the places that need AC the most (flats) will probably not be able to get it until the leasehold system has been abolished.

Presumably it means heating using electric heat pumps rather than gas boilers. This also solves the AC problem. I don't think this is viable for most people. Heating was never the problem anyway, at least in the south winters are mild.

well, i live in lincolnshire and used to live in london. i usually have a fan on for a few weeks over summer, but that's it. where in the UK did you live that the summers were so unbearable?

That's only a few weeks a year. The UK isn't Florida yet. And besides modern AC is incredibly efficient. The stuff that's cleared to sell in Europe has incredibly high standards.
