Scottish Industrial Energy Transformation Fund: guidance - competition three

Guidance notes and application forms for the third call of the Scottish Industrial Energy Transformation Fund (SIETF).

This document is part of a collection

Pre-application information

*You should read all the guidance in this section before starting an application within the competition that is relevant to your project.

Key eligibility criteria

Proposals for energy efficiency and deep decarbonisation deployment projects must:

  • improve energy efficiency, and/or decarbonise, an industrial process at a site located in Scotland following installation and commissioning of the energy efficiency or decarbonisation measure. The technology must already be proven to work through test and demonstration and/or successful operation. Previous test and demonstration and/or successful operation of the technology does not have to have been at the applicants site

Key criteria for demonstrating additionality for deployment projects:

  • the project will not go ahead in its current form without SIETF funding. The application should state how the project, in the form and to the timetable as proposed, is additional to what would have taken place without SIETF funding
  • describe/explain what would happen without SIETF funding through normal investment processes. This could include: why you are not able to wholly fund the project from your own resources or other forms of private-sector funding, the likely impact of the project on the businesses of the collaborators involved, how this project goes above and beyond your existing energy and carbon reduction commitments
  • more detail is within application form such as: provide details of company investment criteria and how much investment is made annually on energy improvement projects

Further detail on feasibility and FEED eligibility criteria can be found in the eligibility section.

To be eligible for this competition, the lead applicant must carry out an eligible industrial process. The business standard industrial code (SIC) code should fall into the following category:

  • manufacturing SIC codes 10000 to 33200
  • data centre 63110
  • mining and quarrying SIC codes 05101 to 05200, 07100 to 08900 and 09900
  • recovery and recycling of materials 38320

If a business carries out work under various SIC codes (inc manufacturing codes) but their official SIC isn't eligible, the lead applicant should provide evidence to before starting their application that the main activities taking place on the site match one of the eligible SIC codes.

If you are requesting a deployment grant that exceeds £2 million, or a study grant that exceeds £100,000, you must inform us before submitting an application. Please email at least 10 working days before the competition closes, stating the technology your project is focusing on and the total grant you expect to apply for. Note that these are not the maximum grant thresholds under each competition, but this step will inform us in advance of application window closure of potential projects that may wish to access a relatively large proportion of available funds.

SIETF will consider cases where there are plans to relocate an industrial production line (or lines) and as part of this relocation in Scotland, the applicant chooses to upgrade heat or energy producing plant that are part of the industrial process. However, for SIETF to consider the specific elements which can be identified as energy efficiency or emission saving measures must be clearly presented as additional to a wider package of measures that constitute the overall relocation (or consolidation) investment. Applications where relocation is a factor are still subject to the exclusions listed within this guidance.

Lead applicant

To lead a project or work alone, your organisation:

  • must be a business of any size registered in the UK that operates at a manufacturing site with SIC codes, as above, in Scotland where the project is carried out. Check your business SIC code
  • can collaborate with other businesses, research organisations, research and technology organisations (RTO), academic institution or public sector organisations which must all be registered in Scotland or other parts of the UK
  • cannot be an undertaking in difficulty

Third parties (for example, a consultancy or an energy service company) may prepare an application on behalf of the lead applicant. However, the grant provider will not have a legal relationship with or pay money to a third party, or anyone other than a lead applicant

Company SIC code versus manufacturing site SIC code

  • some large companies will have various entities and the manufacturing site may be managed by an entity with non-eligible SIC code
  • if you belong to a larger company who has a non-eligible SIC code, but a site contains manufacturing, then your project may still be eligible subject to providing clear information that the process/activities which the project or study will address match an eligible SIC code

Relationship between technology provider and manufacturing site

  • in some instances, a technology provider may propose installing and operating an energy efficiency technology at a manufacturing site and the site either does not pay capital costs up front, or does not pay for the technology at all. The fund will accept applications using this business model 
  • if the lead applicant is not the owner of the capital investment, this should be transparent in the application form. Information regarding the contractual arrangements between site and technology provider will be reviewed as part of the application process and we may seek additional clarifications regarding deliverability and risk


To collaborate with the lead, an organisation can be a business of any size, a research organisation, RTO, an academic institution or a public sector organisation.

The lead must claim funding by entering their costs during the application. If the lead is collaborating with other organisations, then the lead and at least one other partner must claim grant funding and enter their costs into the application form. Further clarification can be found in finance section.

Each partner organisation must be invited to participate by the lead to collaborate on a project. Partners must enter their own project costs into the application.

Your project can include partners that do not receive any of this competition funding, for example non-Scottish or non-uk businesses. Their costs will count towards the total eligible project costs.

Working with an overseas partner

  • you can work with international partners, but they can't claim grant unless they are registered in the UK
  • you can also use international subcontractors, though in your application form you should explain why you need to use an international rather than UK-based company


Subcontractors are allowed in this competition and can be from anywhere in the world. We would expect subcontractor costs to be justified and appropriate to the total eligible project costs. You must make sure they are sufficiently qualified for their role.
