Question
To ask the Scottish Government how many renewable heating systems it estimates were installed in homes in each of the last five years, and how many such installations will be required annually over the next eight years to meet the 2030 target under its Heat in Buildings Strategy.
Answer
The Energy Saving Trust maintains the Renewable Heat Database for the Scottish Government. The following table extracts domestic renewable heat installations over the period 2016-2020. Data for 2021 are not yet available. These data are derived from registrations under the Microgeneration Certification Scheme, and as such likely underestimate the total number of installations due to lower coverage of new build homes.

Technology | 2016 | 2017 | 2018 | 2019 | 2020 |
Air Source Heat Pump | 1,305 | 1,269 | 1,737 | 2,243 | 2,477 |
Biomass | 388 | 187 | 102 | 74 | 69 |
Ground/Water Source Heat Pump | 150 | 193 | 160 | 175 | 430 |
Solar Thermal | 170 | 164 | 89 | 135 | 79 |
Total | 2,013 | 1,813 | 2,088 | 2,627 | 3,055 |
Reaching our emissions targets requires a significant acceleration in installation of zero emissions heat technologies in homes and installation of connections to heat networks, recognising the time needed for supply chains to grow. As set out in the 2021-22 Programme for Government, domestic installations must scale up such that the total number of installations between 2021 and 2026 is at least 124,000. The Heat in Buildings Strategy sets out that installation rates will need to peak at over 200,000 per year in the latter part of this decade.
