Solar panels and batteries at the moment are paying back in about 7 years and that is without any government grant, you can potentially get it down to 5 with a bit more risk taken on with not tier 1 kit and installers. Or put another way you pay up front for the next 25 years to pay 8p a KWh (instead of ~35p).
Comparatively I can’t make a heatpump do anything but cost more for heating over the next 25 years, it never pays off in its lifetime. An air to air heatpump however should be equivalent to a boiler but they cost about 1/3 of the to water ones which seem to be enormously overpriced compared to other countries that do something similar (Norway).
