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

To be fair, they make heat pumps and I'm sure they wouldn't mind selling a few.
Suspect it's more along the lines of
- the UK has cold weather
- the UK has poorly insulated houses
- you can't fix either of things, easily and cheaply and quickly, despite what those loons blocking the roads say
- airsource heatpumps don't work efficiently in very cold conditions, when you need them most
-> hybrid system
Will be great for the serving guys doing two jobs on one site....

I know the future of central heating gets discussed in this thread occasionally. Vailant have come up with a white paper 'Decarbonising Home Heating In The UK' available for download via the link :-

I've not read it yet but they're a big player in the marketplace at the moment so it should be interesting.
