How to Apply for Innovate UK Smart Grants (2026 Guide)
A comprehensive, step-by-step guide to one of the UK's most important innovation funding programmes. Whether you are a climate tech startup preparing your first bid or an established SME looking to improve your success rate, this guide covers everything you need to know about Smart Grants in 2026.
What Are Innovate UK Smart Grants?
Smart Grants are Innovate UK's flagship open funding programme, designed to support game-changing and disruptive research and development projects across every sector of the UK economy. Unlike themed competitions that target specific industries or challenges, Smart Grants accept applications from any technology area and any business domain. This open scope makes them one of the most versatile and widely used routes to public R&D funding for innovative UK companies.
Administered by UK Research and Innovation (UKRI) through Innovate UK, Smart Grants have been running in various forms since 2017. They replaced the previous Open programme and have since become the single largest source of Innovate UK grant funding by total value awarded. In 2025 alone, Smart Grants funded over 800 projects with a combined value exceeding £350 million.
For climate technology companies, Smart Grants are particularly valuable. The programme does not require you to fit into a predefined sector theme. Whether you are developing novel battery chemistries, carbon capture membranes, smart grid software, green hydrogen electrolysers, or sustainable building materials, your project can compete on its own merits. The assessment criteria reward innovation, commercial potential, and wider impact, areas where climate tech typically scores strongly.
Smart Grants also serve as a credibility signal. Winning an Innovate UK grant is recognised by investors, corporate partners, and other funders as evidence that your technology and team have been independently validated. Many climate tech companies use a Smart Grant as a springboard to larger programmes such as Horizon Europe, the Net Zero Hydrogen Fund, or DESNZ energy innovation calls.
Eligibility: Who Can Apply?
Smart Grants are open to any UK-registered business. There are no restrictions on company size, age, or sector. Sole traders, micro enterprises, SMEs, and large companies can all apply. However, large companies must demonstrate that the public funding is necessary and that the project would not happen without it. In practice, the vast majority of successful applicants are SMEs.
Your business must be registered at Companies House and have a UK operating base. The project work must be carried out predominantly in the UK, and the results must be exploited from the UK. International collaboration is permitted for collaborative projects, but the lead applicant must always be a UK-registered business.
Research organisations (universities, RTOs, catapult centres) can participate as project partners in collaborative bids but cannot lead a Smart Grant application. Academic partners typically receive 80% funding for their project costs.
The project itself must involve genuine industrial research or experimental development. Pure blue-sky research with no commercial route is not eligible, nor are projects that are essentially product development with no technical risk. Innovate UK typically looks for projects in the Technology Readiness Level (TRL) 3 to 7 range: beyond basic research but not yet at the point of commercial production.
Key Eligibility Requirements at a Glance
- UK-registered business (Companies House)
- Project work carried out predominantly in the UK
- Industrial research or experimental development (TRL 3-7)
- Clear commercial exploitation plan for the UK
- Single-company or collaborative (2+ partners) projects
- Match funding available for your share of project costs
Funding Details: How Much Can You Get?
Smart Grants fund projects across two structures: single-company projects and collaborative projects. The funding amounts and rules differ between the two.
Single-company projects can request between £25,000 and £500,000 in grant funding. The total project cost (grant plus your match funding) will therefore be higher. These projects must last between 6 and 18 months and are led and delivered by a single business, though you can subcontract specialist work to third parties.
Collaborative projects involve two or more partner organisations and can apply for total grant funding of up to £2 million across all partners. Collaborative projects can last between 6 and 36 months. At least one partner must be an SME, and the lead applicant must be a UK-registered business.
The percentage of your eligible costs that Innovate UK will fund depends on two factors: the size of your company and the category of research activity. These rates are set by state aid rules and are non-negotiable.
| Company Size | Industrial Research | Experimental Development |
|---|---|---|
| Micro / Small | Up to 70% | Up to 45% |
| Medium | Up to 60% | Up to 35% |
| Large | Up to 50% | Up to 25% |
Understanding the distinction between industrial research and experimental development is critical for your budget. Industrial research covers the acquisition of new knowledge and skills directed at developing new products, processes, or services. Experimental development is closer to market. It involves prototyping, testing, piloting, and validation of a new or improved product in a representative environment.
Many climate tech projects contain elements of both. A project that develops a new catalyst formulation (industrial research) and then integrates it into a pilot reactor (experimental development) would split costs between the two categories. The blended funding rate will sit somewhere between the two percentages. Getting this split right in your finance form is important. Assessors will challenge applications where the categorisation does not match the described work.
Eligible costs include labour, materials, capital equipment (depreciation over the project period), subcontracting, travel, and overheads. Innovate UK applies a flat 20% overhead rate to labour costs for businesses. You cannot claim costs that were incurred before the project start date.
The Application Process: Step by Step
Smart Grant applications are submitted through the Innovation Funding Service (IFS), Innovate UK's online portal. The process is entirely digital. There is no paper application and no physical submission. Here is a step-by-step walkthrough of the process from start to finish.
Register on the Innovation Funding Service
Create an account on the IFS portal if you do not already have one. Register your organisation and ensure your company details are up to date. For collaborative projects, every partner organisation needs its own IFS account.
Start Your Application
Navigate to the Smart Grants competition page and click 'Start new application.' You will be asked to provide a project title, select your project type (single company or collaborative), and add any partner organisations.
Complete the Application Form
The form contains several sections covering your project scope, approach, innovation, team, project management, risks, costs, wider impacts, and exploitation plan. Each section has a word limit, typically between 400 and 600 words. Write concisely and directly address the assessment criteria.
Complete the Finance Forms
Enter detailed project costs broken down by category (labour, overheads, materials, capital, subcontracting, travel, other) and by financial year. Each partner completes their own finance form. Costs must be justified and reasonable.
Submit Before the Deadline
Smart Grants operate on a rolling basis with periodic assessment rounds. Check the current competition page for the next deadline. Late submissions are not accepted under any circumstances. Submit at least 24 hours early to avoid technical issues.
Assessment and Interview
Applications are assessed by a panel of independent assessors with relevant domain expertise. Approximately 25-30% of applications are invited to an interview, which is typically a 30-minute video call with a 10-minute presentation followed by Q&A. Not all competitions include an interview stage.
Funding Decision and Grant Setup
Successful applicants receive a conditional offer letter. You then complete due diligence checks (subsidy control, financial viability) and negotiate a grant offer letter. Once signed, the project can start and you can begin claiming costs.
Assessment Criteria: What Assessors Look For
Innovate UK assessors evaluate Smart Grant applications across five scored sections. Each section is scored on a scale of 1 to 10, and applications need to achieve a minimum threshold score (typically 7 out of 10 on each section) to be considered for funding. Understanding these criteria in depth is the single most important factor in writing a winning application.
1. Scope: Your Vision and Innovation
This section evaluates the novelty and ambition of your project. Assessors want to understand what problem you are solving, why current solutions are inadequate, and what makes your approach genuinely innovative. For climate tech, clearly articulate the environmental problem, quantify the scale of the opportunity, and explain how your innovation represents a step change rather than an incremental improvement. Reference the current state of the art and position your innovation relative to competing approaches. Avoid generic claims about market size. Be specific about your target application and why your solution is better.
2. Approach: Your Project Plan
Describe what you will actually do during the project. Break the work into clearly defined work packages with specific deliverables, milestones, and timelines. Assessors want to see that you have thought carefully about the technical approach, that your methodology is sound, and that the work programme is realistic for the budget and timeframe. Include your risk register. Identify the key technical and commercial risks and explain your mitigation strategies. Climate tech projects should address scale-up risks, supply chain dependencies, and regulatory pathways.
3. Team: Your Capability to Deliver
This section assesses whether your team has the skills, track record, and capacity to deliver the project. Name key individuals and describe their relevant experience. If you have previously delivered Innovate UK or other publicly funded projects, mention this. It demonstrates you understand the reporting and governance requirements. For collaborative projects, explain why each partner is essential and how the consortium brings together complementary skills. Identify any skills gaps and explain how you will fill them, whether through recruitment, subcontracting, or advisory board members.
4. Funding and Value for Money
Assessors examine whether your costs are realistic, justified, and represent good value for public money. Every cost line should be clearly linked to specific activities in your work plan. Labour costs should reflect actual salaries (not inflated day rates), subcontracting should be justified on the basis of specialist expertise you do not have in-house, and capital equipment costs should reflect genuine project needs. Explain why the project cannot proceed without public funding. This "additionality" argument is essential. Also demonstrate that you have secured or have a credible plan to secure your match funding contribution.
5. Impact and Exploitation
This is often where climate tech applications can differentiate themselves. Describe the economic, social, and environmental impact of your project. Provide specific, quantified projections: revenue forecasts, jobs created, tonnes of CO2 avoided, energy savings, or waste diverted. Assessors want to see a credible route to market: who will buy your product, at what price, and through which channels? Include an IP strategy and explain how you will protect and exploit the results. For climate tech, link your impact to UK net zero targets and relevant policy frameworks. A strong dissemination plan showing how you will share knowledge beyond the project also scores well.
Timeline: When to Apply and What to Expect
Smart Grants operate on a rolling basis, meaning the competition is open continuously throughout the year. However, applications are assessed in periodic rounds, typically quarterly. Innovate UK publishes the dates for each assessment round on the competition page, and you need to submit before the round closing date for your application to be included in that batch.
The typical timeline from submission to funding decision is approximately 3 to 5 months. After the assessment round closes, applications go through an initial eligibility check, then independent expert assessment, then panel moderation where scores are calibrated across all applications in the round. Shortlisted candidates may be invited to interview before final decisions are made.
For the 2026 financial year, Innovate UK has confirmed that Smart Grants will continue with quarterly assessment rounds. Budget availability can fluctuate between rounds depending on overall UKRI allocations, so it is worth monitoring announcements from Innovate UK about available funding.
If you are planning your application timeline, work backwards from the assessment round deadline. Allow at least 4 to 8 weeks for application preparation, or more for collaborative projects where you need to coordinate multiple partners. If this is your first grant application, allow additional time for getting registered on the IFS portal, understanding the finance forms, and gathering supporting evidence such as letters of support from potential customers.
Recommended Preparation Timeline
- 8 weeks before:Define project scope, confirm partners, begin drafting
- 6 weeks before:Complete first draft of all application sections
- 4 weeks before:Internal review, refine costs, secure letters of support
- 2 weeks before:External review (peer or professional), final revisions
- 1 week before:Final proofread, check all sections and finance forms, submit
Common Mistakes: Why Applications Fail
Having reviewed hundreds of Smart Grant applications over the years, certain failure patterns appear repeatedly. Avoiding these common mistakes can significantly improve your chances of success.
Weak Innovation Narrative
The most common reason for low scores in the Scope section is failing to clearly articulate what is genuinely novel about your approach. Saying your product is 'better' or 'cheaper' is not enough. You must explain the specific technical advance, why it has not been achieved before, and what new knowledge your project will generate. Assessors are domain experts. They will know if your claimed innovation is actually the current state of the art.
Vague Work Plan
Applicants often describe their project at a high level without sufficient detail about methodology, milestones, and deliverables. Assessors need to see that you have a concrete, executable plan. Break your work into 3 to 5 work packages, each with specific objectives, activities, outputs, and success criteria. Ensure the timeline is realistic and include decision gates where you will evaluate progress before committing to the next phase.
Unjustified Costs
Submitting a budget without clear justification is a red flag. Every cost line should map directly to activities in your work plan. Assessors will question labour costs that seem inflated, subcontracting that could be done in-house, or capital equipment that is not essential to the project. Provide brief justifications for each significant cost item and ensure your total costs are proportionate to the project scope.
Missing Additionality Argument
Innovate UK needs to know that public funding is necessary for the project to proceed. If it looks like you could fund the project yourself or attract private investment to do it, your application will score poorly on value for money. Explain the specific barriers, such as technical risk, long payback period, and market uncertainty, that make grant funding essential to de-risk the project.
Generic Impact Claims
Stating that your project will 'help the UK reach net zero' without quantification is not enough. Assessors want specific, defensible numbers: how many tonnes of CO2 will your technology avoid per year at scale? What is the addressable market size? How many jobs will be created in the first 3 years? What revenue do you project? Back up your claims with references and clearly state your assumptions.
Poor Presentation and Readability
Assessors review dozens of applications in each round. A poorly structured, jargon-heavy application with no clear headings or logical flow will frustrate assessors and lose marks. Use clear headings that mirror the assessment criteria, write in plain English, and use bullet points and tables where appropriate. Have someone outside your immediate team read the application before you submit. If they cannot understand it, neither will an assessor.

Smart Grants are Innovate UK's open, continuously competitive funding programme for game-changing and disruptive innovations. Unlike themed competitions, Smart Grants accept applications from any sector and any technology area, making them one of the most accessible routes to public R&D funding for UK businesses.
How much funding can I get from a Smart Grant?
Single-company projects can apply for between £25,000 and £500,000. Collaborative projects involving multiple partners can apply for up to £2 million in total. Funding rates depend on company size and research category: micro and small enterprises can receive up to 70% of eligible costs for industrial research projects.
How long does the Smart Grant application process take?
Smart Grants operate on a rolling basis with assessment rounds roughly every quarter. From submission to funding decision typically takes 3 to 5 months. However, preparing a competitive application usually requires 4 to 8 weeks of dedicated effort, so you should plan for a 6 to 9 month timeline from initial planning to receiving funds.
Can startups and early-stage companies apply for Smart Grants?
Yes. Smart Grants are open to any UK-registered business regardless of size or age. Early-stage companies often perform well because the programme values novelty and disruptive potential. However, you must demonstrate that your project is beyond the pure research stage and that you have a credible plan to exploit the results commercially.
What is the success rate for Innovate UK Smart Grants?
Innovate UK does not publish an official success rate for Smart Grants, but industry estimates suggest it sits between 10% and 15% in most rounds. For climate tech applications with strong commercial traction and clear impact metrics, well-prepared bids can achieve significantly higher success rates, particularly when supported by experienced grant writers.
Do I need match funding to apply for an Innovate UK Smart Grant?
Yes. Smart Grants require the applicant to cover a proportion of eligible project costs. The exact match funding requirement depends on your company size and the type of research. Small enterprises need to cover at least 30% of industrial research costs and 55% of experimental development costs. The match can come from your own resources or other private funding. It does not have to be cash already in the bank, but you must demonstrate a credible plan to secure it.
