I think right now it’s absolutely pointless even with the grant.
They are still miles from being a good alternative to gas rn sadly.

Happily this is not true

Thankfully, you are wrong on this. Heatpumps are used throughout northern Europe, which have much lower temperatures through the winter than we do.
The problem with UK housing stock is the lack of insulation, something that has been exacerbated by a lack of government will to mandate proper insulation in new build homes.

I had a heat geek round today to do a survey with a view to putting in a heat pump. I was very excited!
Full details to come in a week or so, but it looks like it's gonna need to be a large pump. The heat geek calculator was telling him it would need to be 12 KW, mainly on account of solid brick walls and a reasonably large home. We also want to be able in the future to build in 2 copper bath tubs in the garden. This I think is gonna be one of the big issues, as the units are huge, and there are very few places we could feasibly put it. I think most likely is wall mounted over our single storey rear extension. Apparently we'd need to brick or change to a non closing window there, though, as it is not allowed to be within a certain distance of an opening window. Apparently we'll need to get planning permission as it is a larger unit.
He also recommended a full re-pipe as some of the house is 200 years old and some of the ground floor radiators are using 10mm plastic pipes currently.
I suspect I might fall off my chair when we get the quote back. It'll be interesting to see what the estimated cost saving on energy per year will be and therefore how long to pay back the investment. With the current gas boiler the energy bills are really very frightening in the winter months.
