He’s now moved into a new build house that has a heat pump fitted, and it’s working really well.

Heat pumps in the right house are great, in an older poorly insulated house they’re usually a disappointment, which was always his professional view.
Sounds like he wasn't a plumber, but not 'quite' an engineer either..............

Like any heating system - the heating system has to match the heat loss of the building.

Like any method - there are chancers who will convince you that their system is the dog's danglies.

Before spaffing out ££thousands - you need either sound thermodynamics analysis, or at least an absolute comparable case - to make your mind up.
