And
then you claimed there were no heat pumps in the UK, so I provided
you with links that show dozens of companies installing them in just
the London area.

He is probably going to say he doesn't live in London. The Scots may
not even go there.

London's climate is not significantly different, and I'm sure they have gas. And I know several Londoners, who all just use gas. Since gas is 2.5p instead of 11.5p a unit, a heat pump isn't yet economically viable.

Heat pumps are most common with people who need air conditioning in
the summer. It is a small up charge to add the reversing valve.
If you are using ground source pumps, that also makes sense in you
need to use electricity but I agree, for pure heat, you can't beat
piped gas if it is available.
