Heat and Energy Efficiency Technical Suitability Assessment (HEETSA) - Scoping Consultation
Overview
The purpose of this Scoping Consultation is to set out the Scottish Government’s initial proposals for the scope of a Heat and Energy Efficiency Technical Suitability Assessment (HEETSA) and seek stakeholder views on the overall concept of HEETSA and how it relates to other parts of the heat and energy efficiency retrofit landscape.
The Scottish Government’s objective in making these initial proposals is to safeguard consumers by developing a technical suitability assessment which ensures that building owners can understand which measures are appropriate, i.e. identify the ‘right’ measures when improving their energy efficiency and changing their heating systems.

Consultation questions preview
The consultation questions are included here for your reference. Please click 'Begin consultation' at the bottom of this page to proceed.
- To what extent to you agree or disagree that it would be valuable for the Scottish Government to develop a HEETSA (a government-led approval and accreditation mechanism to provide oversight and standardisation of the retrofit assessment market)?
- If the Scottish Government develops a HEETSA, which of the following should it cover: Retrofit assessment, Retrofit design, Retrofit specification, Installation, Evaluation, Occupancy and/or Other.
- Which delivery model do you think would be most appropriate for HEETSA: Direct Government accreditation of assessors, Government accreditation of assessor organisations who in turn accredit assessors, HEETSA as guidance only without Government accreditation of assessors or Other.
- What methodologies would be needed to meet the requirements of a HEETSA?
- There are a range of ways that identified gaps could be filled – by the market, or by the Scottish Government procuring and developing methodologies to do this. What do you think is the best approach to filling identified gaps in the methodologies required for HEETSA?
- What skills and qualifications should be required to undertake a HEETSA?
- Which of the following statements comes closest to your view: It is feasible for an individual assessor to have sufficient skills and knowledge to complete a HEETSA, A HEETSA would require input from multiple specialists and could not be completed by an individual, Don’t know, Other - please specify
- To what extent do you agree or disagree that non-personal data gathered through a HEETSA should be stored to form part of a ‘building logbook’ or ‘green building passport’?
- To what extent do you agree or disagree that the HEETSA assessor should be required to be independent of the outcome of the assessment? E.g. they could not financially gain from the outcome if a measure is stated as technically suitable.
- Thinking about the relationship between the EPC and HEETSA, which of the following statements comes closest to your view: The results of a HEETSA should result in the production of a revised EPC as part of its output, The results of a HEETSA should be made available to inform the production of a revised EPC and should be considered acceptable ‘documentary evidence’ to override default values, The results of a HEETSA should not have any influence on the EPC and its ratings, Don’t know or Other.
- Thinking about presenting the results of a HEETSA, please give your view on: a) Whether a HEETSA should result in a standardised certificate or report? b) What information should be included when presenting the results?
- Please provide details of any circumstances in which you think a HEETSA should be required, and the reasons for your view.

Why your views matter
Consultation is an essential part of the policymaking process. It gives us the opportunity to consider your opinion and expertise on a proposed area of work.
You can find all our consultations online.
Responses will be analysed and used as part of the decision-making process, along with a range of other available information and evidence. We will publish a report of this analysis for every consultation. Depending on the nature of the consultation exercise the responses received may:
- indicate the need for policy development or review
- inform the development of a particular policy
- help decisions to be made between alternative policy proposals
- be used to finalise legislation before it is implemented
While details of particular circumstances described in a response to a consultation exercise may usefully inform the policy process, consultation exercises cannot address individual concerns and comments, which should be directed to the relevant public body.
