Owning your own home

The problem with all this is it falls to the home owner to foot the bill, people dont want to spend money right now on cheapish stuff never mind the alternatives. The big company's really need to work on the pricing for these things for people to change/invest in them.

TLDR: They want to sell you a new gas boiler:

1. Fit a high efficiency gas boiler, improve the building fabric to
   reduce the energy required and adapt the system to operate at lower
   mean water temperatures which gives 6%-8% efficiency and carbon
   improvement
   
2. Add a heat pump to the incumbent boiler to create a hybrid system. The heat pump could cover up to 80% of the annual heat load
   
3. Switch the high efficiency gas boiler to a hydrogen boiler in future once hydrogen becomes available. Hydrogen-ready boilers will be
   available within the next few years which would make this conversion a
   simple process rather than a boiler change
   

Funny that.
