I was curious how much the government incentives were driving domestic adoption.

These are the latest government total stats since 2014 unless I have miss understood the stats which wouldn't be the first time...

GOV.UK "https://www.gov.uk/government/collections/renewable-heat-incentive-statistics"

Renewable Heat Incentive statistics - GOV.UK

This series brings together all documents relating to Renewable Heat Incentive statistics.

Number of domestic accreditations by technology type, Great Britain, April 2014 to April 2021

Total (New & legacy installations)

Air source heat pump 55,264
Ground source heat pump 11,958
Biomass systems 12,370
Solar thermal 8,958

Total 88,550

Has anyone seen any other domestic stats?

These are just RHI numbers so that would not include most new builds or anyone else who didn't get RHI. There must be quite a few of these.

There is some analysis of EPCs here that looks at percentage split of different heating systems.

ONS.GOV.UK "https://www.ons.gov.uk/peoplepopulationandcommunity/housing/articles/energyefficiencyofhousinginenglandandwales/2020-09-23"

Energy efficiency of housing in England and Wales - Office for National Statistics

Analysis of the energy efficiency, estimated carbon dioxide emissions and energy cost of dwellings in England and Wales with an Energy Performance Certificate.

Yes the separate stats I saw was the majority of installs are new build, some off grid property refit, on grid was so small to be insignificant.

I was curious about the incentives to switch rather than new builds and what impact they were having.

I was surprised just how small the refit market has been to date so looked at the RHI numbers

The number of domestic RHI accreditations for ashp for 2021 is now on the government website

13918

In 2020 it was 9468.

Of course there will be other domestic non RHI installs.

The RHI replacement scheme (£5k) is funded for 30k domestic installs per year for 3 years.
