1. The latest available figures are based on 2018 data.
2. Total domestic, industrial and commercial non-electrical heat demand.
3. The Climate Change Committee estimated in 2015 that with government support, heat networks could provide 18% of UK heat demand by 2050 in a least-cost pathway to meeting UK carbon targets.
4. Source: Scottish Government estimate using BEIS' 2018 energy and emissions projections for grid emissions intensity, 8% distribution losses and a co-efficient of performance of 2.7.
5. Examples include heat networks in Lerwick, Skagen, 8 others in Denmark associated with solar thermal and large scale storage including in Silkeborg.
6. See Chapter 2, Contribution to eradicating fuel poverty section.
7. The 2021 Act states "Each local authority must carry out a review to consider whether one or more areas in its area is likely to be particularly suitable for the construction and operation of a heat network." Details of what must be considered in the review for heat network zoning is set out in more detail in Part 3 (Sections 47, 48) of the 2021 Act.

13. Figure is a broad estimate, using data from Non-Domestic Buildings Energy Database and ePIMS (ePIMS may include buildings outwith the scope of Part 5, sec. 76 (a) the 2021 Act).
14. Part 2 (Section 33) of the 2021 Act allows Scottish Ministers to determine the form and manner in which a relevant application is to be made, and the information (including the information in the form of a document) that is to be included in a relevant application.
