Investor Partnerships – Battery Innovation Programme

Your project

The eligibility criteria will depend on your research category.

For feasibility studies projects:

• your total project costs must be between £50,000 and £300,000

• the project duration must be between 6 and 12 months

For industrial research projects:

• your total project costs must be between £100,000 and £1 million

• the project duration must be between 6 and 24 months

For experimental development projects:

• your total project costs must be between £250,000 and £2 million

• the project duration must between 12 and 24 months

Projects must always start on the first of the month, even if this is a non-working day. You must not start your project until your Grant Offer Letter has been approved by Innovate UK. Any delays within Project Setup may mean we need to delay your project start date.

You must only include eligible project costs in your application. See our overview of eligible project costs.

Your organisation

This competition is open to single applicants only. To apply your organisation must:

• be a UK registered micro, small or medium sized business (SME)

• carry out its project work in the UK

• intend to exploit the results from or in the UK

• be invited to apply by your investor partner

• have discussed and agreed your proposal with your investor partner before submitting your application

More information on the different types of organisation can be found in our Funding rules.

Subcontractors

Subcontractors are allowed in this competition.

Subcontractors can be from anywhere in the UK and you must select them through your usual procurement process.

You can use subcontractors from overseas but must make the case in your application as to why you cannot use subcontractors from the UK.

You must provide a detailed rationale, evidence of the potential UK contractors you approached and the reasons why they were unable to work with you. We will not accept a cheaper cost as a sufficient reason to use an overseas subcontractor.

All subcontractor costs must be justified and appropriate to the total eligible project costs

Number of applications

An SME can only submit one application into this round of the competition.

Sanctions

This competition will not fund you, or provide any financial benefit to any individual or entities directly or indirectly involved with you, which would expose Innovate UK or any direct or indirect beneficiary of funding from Innovate UK to UK Sanctions. For example, through any procurement, commercial, business development or supply chain activity with any entity as lead, partner or subcontractor related to these countries, administrations and terrorist groups.

Use of animals in research and innovation

Innovate UK expects and supports the provision and safeguarding of welfare standards for animals used in research and innovation, according to best practice and up to date guidance.

Applicants must ensure that all of the proposed work within projects, both in the UK and internationally, will comply with the UKRI guidance on the use of animals in research and innovation.

Any projects selected for funding which involve animals will be asked to provide additional information on welfare and ethical considerations, as well as compliance with any relevant legislation as part of the project start-up process. This information will be reviewed before an award is made.

Previous applications

You can use a previously submitted application to apply for this competition.

If you have previously submitted an application that reached our assessment stage, you can re-apply once more with the same proposal.

If there are minor differences to the proposal, but it is judged by us to be ‘not materially different’, the same rule applies.

We will not award you funding if you have:

• failed to exploit a previously funded project

• an overdue independent accountant’s report

• failed to comply with grant terms and conditions

Innovate UK may withhold a grant payment at any time if you have any outstanding sums due to us in relation to other projects.

Subsidy control (and State aid where applicable)

This competition provides funding in line with the Subsidy Control Act 2022. Further information about the Subsidy requirements can be found within the Subsidy Control Act 2022.

Innovate UK is unable to award organisations that are considered to be in financial difficulty. We will conduct financial viability and eligibility tests to confirm this is not the case following the application stage.

EU State aid rules now only apply in limited circumstances. See the Windsor Framework to check if these rules apply to your organisation.

In the ‘Project details’ section of your application you will be asked questions to indicate if State Aid or Subsidy applies to your organisation.

Further Information

If you are unsure about your obligations under the Subsidy Control Act 2022 or the State aid rules, you should take independent legal advice. We are unable to advise on individual eligibility or legal obligations.

You must not do anything which could cause a breach of Subsidy Control legislation applicable in the United Kingdom.

This aims to regulate any advantage granted by a public sector body which threatens to, or distorts competition in the United Kingdom or any other country or countries.

Funding

A minimum of £5 million has been allocated to fund innovation projects in this competition. This is subject to us receiving a sufficient number of high quality applications. Funding will be in the form of a grant.

You will only receive Innovate UK grant funding if you also secure aligned investment at or above the minimum required for the relevant research level.

Your investor partner must also submit a “Declared Minimum Aligned Investment”, which you must confirm with your investor partner.

Before any funding decision, we will ask the investor partner to confirm the Declared Minimum Aligned Investment. If the Declared Minimum Aligned Investment is higher than the minimum required for the relevant research level, it will be treated as greater leverage and will strengthen our assessment of additionality unless there is a strong justification not to.

However, at the same time, the confirmed Declared Minimum Aligned Investment becomes the new Minimum Aligned Investment. Your project cannot start until this amount has been secured.

Innovate UK will decide which projects are eligible and in scope to receive grant funding.

The decision will be based on three factors:

1.   Innovation: Assessed by independent assessors based on your application.

2.   Additionality: Based on the impact of the grant in accelerating your innovation and leveraging the aligned investment. Assessed by the Investor Partnerships Team based on information provided by your named Investor Partner.

3.   Traction: Based on the likelihood of the investment completing within a reasonable timeframe. Assessed by the Investor Partnerships Team based on information provided by your named Investor Partner.

To be successful in this competition, you must score strongly across all three factors.

We will ask your confirmed Investor Partner to provide an update on the progress of your investment prior to making our funding decision. Our assessment of the additionality and traction will be based on this update. It is therefore important that you liaise with your Investor Partner and that their response represents your understanding of the investment position at that time.

If you are successful, you will receive grant funding to cover a proportion of the costs of your project. The project will only be allowed to commence once the agreed aligned investment has been confirmed.

Your business must have sufficient capital resources, including through investment from the investor partner and the grant funding, to enable you to meet all your project’s eligible costs.

All recipients must act commercially, and your funding request must not exceed the limits specified.

Feasibility studies and industrial research projects

For feasibility studies and industrial research projects, Innovate UK will fund:

• up to 70% of eligible project costs for micro or small organisations

• up to 60% for medium sized organisations

The absolute minimum aligned investment led by the Investor Partner must always be at least equal to the grant funding.

Experimental development projects

For experimental development projects Innovate UK will fund:

• up to 45% of eligible project costs for micro or small organisations

• up to 35% for medium sized organisations

The absolute minimum aligned investment led by the Investor Partner must always be at least twice as much as the grant funding.

The aim of this competition is to provide you with support for research and development and access to the capital investment you need to develop and commercialise your innovations.

Your proposal must have a clear route to market, a clear link to innovation and evidence that you can create a team to deliver your proposal.

You must be:

• registered in the UK as an SME by the time the award is contracted

• able to complete the aligned investment led by the investor partner needed to qualify for the award, through the issue of new shares or convertible debt

You must also demonstrate that if your project is funded, it will:

• have significant market impact

• be scalable

• be attractive to equity investors

Battery Innovation Programme 

Innovate UK, part of UK Research and Innovation, is delivering the Battery Innovation Programme on behalf of the Department for Business, Innovation, Science and Trade (DBIST). Funding will be considered to high-quality applications that meet one or more of the following criteria:

• accelerate the development and commercialisation of state-of-the-art battery technologies in the UK

• support the growth of the UK battery supply chain and related companies

• enhance the UK’s competitiveness in the global battery market

• demonstrate how battery technologies can meet specific application requirements and drive electrification across diverse sectors

Your proposal can address one or more of the following areas:

• raw materials

• advanced cell materials

• cell design and components

• process and manufacturing tools

• quality control and diagnostics

• testing, simulation and digital tools

Your project can target performance requirements for at least one of the listed sectors and can support emerging use cases or cross sector applicability.

Included sectors:

• automotive sector including on and off-highway vehicles, motorsports and niche automotive

• aerospace

• defence

• battery energy storage systems

• rail

• maritime

• personal mobility

Innovation and ideas can come from anyone and anywhere. We want to see investments unlocked for the diverse and extraordinary talent in the UK.

We encourage innovation involving communities that are typically under-represented, including:

• from regions that have historically accessed lower levels of investment (outside London, Oxford and Cambridge)

• ethnic minority groups

• women and other marginalised genders

• disabled people

• people with non-traditional education backgrounds

Portfolio approach

The Battery Innovation Programme wants to fund a variety of projects within Investor Partnerships. Our initial funding decision is based on the innovation score, investment additionality, expected leverage and likelihood of investment completion.

Where funding is limited within these specific themes, we may make a funding decision based on the project type and size, grant requested, business stage, location, and sector to ensure portfolio balance and alignment with strategic intent. We call this a portfolio approach.

We will also take into account the impact of the grant in accelerating investment and the likelihood of the investment completing within a reasonable time.

Research categories

We will fund feasibility projects, industrial research projects and experimental development projects, as defined in the guidance on categories of research.

Projects we will not fund

We are not funding projects that are:

• collaborative R&D projects

• not part of a company’s growth plan

• unable to prove there is potential for return on investment and growth

• large capital infrastructure

• not invited by a specified investor partner

We cannot fund projects that are:

• dependent on export performance: giving a subsidy to an organisation on the condition that it exports a certain quantity of its products to another country

• dependent on domestic inputs usage: giving a subsidy to an organisation on the condition that it uses a set percentage of UK components in their product

Investor Partnerships – Battery Innovation Programme - Assessor guidance for applicants.pdf (opens in a new window)

Innovate UK, as part of UK Research and Innovation, has selected a pool of investor partners. These investor partners have demonstrated that they have the credibility, capability, capacity and appetite to invest in innovative, technology-led businesses that align with the programmes. These programmes will focus on the future economy as described in our plan for action.

The Investor Partnership programme brings together:

• Innovate UK’s expertise in identifying innovation and using grant funding to change the risk profile of businesses

• investor partners’ aligned funding and expertise in identifying opportunities and teams that can best use extra investment finance

This approach aims to provide you with support for research and development and access to the capital investment you need to develop and commercialise your innovations.

Innovate UK provide support for your investment readiness and for engaging with suitable investors via Innovate UK Business Growth and Innovate UK Business Connect.

In the first instance you should contact Innovate UK Business Growth for support in understanding your readiness for investment and also to look at your wider strategy for growth.

You should also contact Innovate UK Business Connect to establish if there are specific programmes for connecting businesses in your sector to relevant investors. Support and connections to sector specific investors may also be provided by the relevant catapult centre.

You will need to establish a relationship and a level of investment traction with one of our approved investor partners before you apply for funding. A full list of selected investor partners is provided Innovate UK Business Connect investor partnerships website.

The investor partner must have confirmed with you that you are in a position to apply for grant funding as you will be asked to identify them in the application.

To be successful, your project must be independently assessed by Innovate UK as fundable and receive investment directly, led or catalysed by the investor partner.

Briefing recording and slides

Briefing recording and slides will be available to download here after the briefing event.

What happens if you receive a grant offer

If you have passed your initial assessment and have received an email with a grant offer,

you will be asked to complete the project setup process on the Innovation Funding Service (IFS). Watch our video on what steps are there before a project starts.

We will ask for information that will allow us to undertake mandatory checks on your organisation and the eligibility of your costs, as well as review the documentation for your project.

You must follow the unique link embedded in your email notification. This takes you to your project's dedicated IFS Set Up portal, where we gather the information required to set up your project, for example, your bank details. Watch our video on how successful applicants receive their funding.

If your application is unsuccessful

If you are unsuccessful with your application this time, you can view feedback from the assessors. This will be available to you on your IFS portal following notification.

Sometimes your application will have scored well, and you will receive positive comments from the assessors. You may be unsuccessful for any of the following reasons:

• your average score was not above the funding threshold

• your project has not been selected under the portfolio approach

• we were not convinced that the grant was making a significant difference in the investment and in all likelihood the investment would have happened anyway

• you do not have sufficient traction with the investor and we doubt that the investment will complete in a reasonable period of time

• the investment has already been secured

• the selected investor partner is not taking a significant role in leading or facilitating the investment

Find an investor partner

You will need to establish a relationship and a level of investment traction with one of our approved investor partners before you apply for funding. A full list of selected investor partners is provided at Innovate UK Investor Partners – UKRI and Innovate UK Business Connect investor partnerships websites.
