Of course, some of the new builds may be different but the one I know
about wasn't built to include a heat pump.

There was a tiny bit on heat pumps on the radio today. It wasn't on
saving energy but on the cost of running.

The general conclusion was that if you heated your house with mains gas
you would probably save no money by replacing gas heating with a heat
pump. The cost of running a heat pump with electricity plus the gain
of the pump is negated by gas being 4x cheaper per unit.

For other forms of domestic heating the comparison will be different.
