Didn't they already break those rules to put Sunak into power?
Your initial comment was that the average UK house isn't suitable for heat pumps. This is incorrect, in the vast majority of UK homes (including the poorly insulated) they can be heated sufficiently by a heat pump.
Don't spread misinformation. Some installers have fixed prices regardless of the number and size of radiators. There's even solutions out there where a hot water tank can be fitted into a standard kitchen cupboard.
You keep mentioning high temperature units which are less efficient, they are only needed in very niche installs or used by poorly trained installers.
Houses that can't be further insulated simply need a bigger pump and larger radiators to make it work. No need for 70 degree flow temps at all, though 50 is easily achievable. With the government grant Octopus are currently charging not much more than a gas install.
Not true. Heat pumps just need to be sized correctly
Correct, it's the worst most popular place

Try octopus energy, I got a fixed price quote for £2k less than any other installer.
