New Build Heat Standard: consultation - part two

We are seeking views on our detailed proposals for a New Build Heat Standard (NBHS) to prohibit the use of direct emissions heating systems in new buildings warranted from April 2024.

18. References to greenhouse gases are the same as those defined in Section 10 of the Climate Change (Scotland) Act 2009

19. Any 'indirect' emissions previously attributed within the TER calculation, such as carbon factors associated with grid electricity or heat networks, will no longer be within the scope of the regulations as these indirect emissions are regulated by other regimes such as The Greenhouse Gas Emissions Trading Scheme Order 2020 ( and the Heat Networks (Scotland) 2021.

22. The new energy target will be defined in terms of delivered energy, and will complement the implementation of the NBHS: ensuring the focus is on energy consumption – not the production of greenhouse gas emissions (which will no longer be necessary in a ZDEH future).

23. This is a requirement under the Energy Performance of Building (Scotland) Regulations 2008

24. Domestic Energy Performance Certificates (EPC) reform: consultation - (

25. The release of potent greenhouse gases by heat pumps (HFCs) are prohibited by separate regulation that meets our obligations under the UN Montreal Protocol. The Ozone-Depleting Substances and Fluorinated Greenhouse Gases (Amendment etc.) (EU Exit) Regulations 2019. In the absence of evidence of leakage of HFCs during normal operation of the heat pump, these regulations consider them to be ZDEH-compliant.

31. As set out in the Heat Networks Delivery Plan, during 2022 we will develop and consult on further guidance for the designation of heat network zones, building on any Local Heat and Energy Efficiency Strategies (LHEES) guidance with the aim of introducing any secondary regulations required on zoning in early 2023. By early 2024, subject to public consultation, we aim to put in place a functioning regulatory system for heat networks.

32. Local Heat and Energy Efficiency Strategies (LHEES): phase 2 pilots evaluation - (

33. In any circumstance, this would be expected to meet the EU rules on sustainable biomass.

34. 0.4 Changes in the occupation or use of a building that cause the regulations to apply - Building standards technical handbook 2019: domestic - (

35. As set out in our Heat in Buildings Strategy, the Scottish Government is committed to introducing regulations which will prohibit the use of DEH systems in all homes by 2045. It is proposed that these regulations will apply at certain trigger points (with point of sale being considered), with a backstop of 2045 for all remaining homes. The Scottish Government will consult on these proposals in the forthcoming year, and will subsequently introduce primary legislation that will provide the regulatory framework to achieve this. Any new building warranted after 1 April 2024 will automatically be assumed to meet standards for existing buildings.

36. At present, a conversion is required to meet current building standards, either in full or as far as is reasonably practicable. Schedule 6 to Regulation 12 of the building regulation sets out which standards must be met in full and which may be met as far as is reasonably practicable.

37. The need to: eliminate discrimination, harassment and victimisation; advance equality of opportunity; and to foster good relations between persons who share a protected characteristic (and those who do not).
