I regularly see people saying the money would be much more effective, and cheaper per property, if it were spent on more insulation for homes rather than heat pumps. I suppose that doesn't achieve the shift away from gas though.
I've also read the stories of pumps being noisy, expensive and inefficient, particularly when retro-fitted to existing CH.
It's the sort of thing which would normally raise interest but in this instance I've read enough real life stories (from forums, not newspapers) that Ill let it pass for now.
Batteries would be ahead of heat pumps in my preferences but I'm even dubious about whether they are really worth the cost and effort - I can see they look it right now, with extraordinarily high electric prices, but once they start to fall (which could be because of the generation costs coming down or decoupling gas from the generation cost) I'm not so sure.
