All those having success wth heat pumps have houses that are non-standard. Pollytickle says her house has two foot thick walls. A form of insulation in itself.
I keep thinking of standard 19th century houses, those brick built terraces, and semis with walls 9 inches thick and no cavities and blocks of 19th century mansion flats with similar walls, where the only place to put the heat pump is in a window.
I am very uneasy with the concept of the 'one size fits all solution' the government seems to be pursuing. Just as the housing stock in the UK is immensely variable in construction and design, so we ought to be looking at a variety of different solutions for different types of housing in varying conditions.
It has been said thaat those who see a simple solution to any problem are invariably wrong. And here we have the government coming up with a simple solution to a very complex problem.
To think that London, or anywhere else for that matter, does not belong to any one demographic
