Grant Writing Tips: Avoid These Common Mistakes in Your Application
16 May 2025
Securing grant funding can honestly transform your business, providing the financial resources needed to turn innovative ideas into a reality.
Yet the application process is notoriously challenging, with many businesses falling at the first hurdle due to avoidable mistakes.
As someone who's reviewed over 50 applications, I've seen brilliant ideas fail to secure funding simply because of how they presented their case.
In this guide, I'll walk you through the most common pitfalls in grant writing and provide actionable tips to strengthen your application.
Why Grant Applications Get Rejected
Before discussing specific mistakes, it's worth understanding why so many applications fail. Grant funding is highly competitive, with success rates typically hovering around 15-20% for many competitions (some as low as 2-5%).
This means that even strong applications can miss out if they don't tick all the right boxes.
The assessment process is rigorous, with independent experts scoring each question against specific criteria.
If you fall below the threshold in just one area, your entire application could be rejected regardless of how strong the rest of it might be.
Analysis of unsuccessful applications reveals that most rejections stem from a handful of common issues that could have been easily addressed before submission.
Common Grant Writing Mistakes to Avoid
1. Misalignment with Grant Scope
One of the most fundamental errors is applying for a grant that doesn't align with your project. This seems obvious, but it happens surprisingly often.
Where applicants go wrong:
Forcing a square peg into a round hole by trying to make their existing project fit a funder's criteria
Overlooking key eligibility requirements such as project duration, funding thresholds, or collaboration requirements
Failing to read and understand the competition brief properly
How to avoid this mistake: Review the grant guidelines, project scope and eligibility criteria thoroughly. Ask yourself honestly: "Does my project genuinely solve the challenge this grant addresses?"
Remember, assessors are experts at spotting projects that have been hastily adapted to fit a funding opportunity. Your application should demonstrate a natural alignment with the grant's goals.
Tools like Grant Hero can help match your business with the most relevant opportunities based on your sector, stage, and innovation focus, saving you from wasting time on misaligned applications.
2. Weak Problem Definition
Many applications fail to clearly articulate the problem they're solving, which is often the first question assessors evaluate.
Where applicants go wrong:
Focusing too much on their solution without establishing why the problem matters
Making vague statements about market needs without substantiating them
Failing to quantify the problem's impact or scale
How to avoid this mistake: When addressing the "Need or Challenge" question (which is a critical question to get right), remember that assessors are looking for:
Clear articulation of the societal, environmental, or economic challenges your project addresses
Evidence-based statements about the problem's scope and impact
Quantifiable metrics that demonstrate the problem's significance
For example, instead of writing, "There's a need for more efficient renewable energy solutions," you might write: "The transition to renewable energy faces a critical barrier: current storage technology limits capacity to X, costs £Y per unit, and relies on materials with precarious supply chains. Our innovation addresses all three challenges by..."
3. Unclear Innovation Differentiation
Many applications fail to clearly explain what makes their approach innovative compared to existing solutions in a competitive UK funding landscape.
Where applicants go wrong:
Assuming technical complexity equals innovation
Failing to demonstrate awareness of competing solutions
Not articulating their unique selling point
How to avoid this mistake: When answering innovation-related questions, make sure to:
Clearly explain the current state-of-the-art and its limitations
Articulate specifically how your approach differs from existing solutions
Quantify the improvements your innovation offers (e.g., "Our approach reduces manufacturing costs by 43% while increasing efficiency by 28%")
Remember that innovation isn't just about new technology; it can also involve novel business models, processes, or applications of existing technology to new domains.
4. Weak Commercialisation Strategy
Most funders support projects with commercial potential, yet many applications fail to demonstrate a viable path to market.
Where applicants go wrong:
Presenting overly optimistic market projections without supporting evidence
Failing to identify specific customer segments or their needs
Not addressing regulatory, scaling, or adoption barriers
How to avoid this mistake: Your commercialisation plan should include:
Evidence-based market sizing with credible sources
Clear identification of early adopters and why they would buy
Realistic pricing models and revenue projections
Recognition of barriers to entry and strategies to overcome them
Intellectual property strategy
Applications scoring highly on commercial potential typically include specific letters of support or evidence of early customer interest, making your case substantially stronger.
5. Poor Budget Justification
Inadequate financial planning and budget justification can quickly sink an otherwise strong application.
Where applicants go wrong:
Presenting unrealistic cost estimates
Failing to link expenditure to project activities clearly
Inadequate explanation of value for money
How to avoid this mistake: When preparing your financial section:
Break down costs into clear work packages with deliverables
Justify why each cost is necessary for project success
Demonstrate you've considered cost-effective alternatives
Show how the funding creates value beyond what your business could achieve alone
Remember that assessors are looking for the responsible use of funds. Your budget should be ambitious enough to achieve meaningful innovation but prudent enough to demonstrate good stewardship.
6. Weak Impact Assessment
Many applications underestimate the importance of clearly articulating the broader impacts of their project.
Where applicants go wrong:
Focusing solely on commercial benefits without considering wider impacts
Making vague claims about potential benefits without specifics
Overlooking negative impacts or risks
How to avoid this mistake: A strong impact section should:
Clearly articulate economic benefits (jobs created, export potential, productivity improvements)
Address environmental impacts (carbon reduction, resource efficiency, pollution mitigation)
Consider social impacts (health improvements, quality of life enhancements, skills development)
Acknowledge potential negative impacts and how you'll mitigate them
Quantifying impacts wherever possible: "Our process will reduce carbon emissions by 32 tonnes per unit produced" is much stronger than "Our process will help fight climate change."
7. Poor Readability and Structure
Even groundbreaking innovations can fail to secure funding if the application is difficult to read or poorly structured.
Where applicants go wrong:
Dense, technical writing that obscures key points
Failing to answer the questions directly asked
Not using formatting to enhance readability
How to avoid this mistake: When writing your application:
Use clear, concise language free of unnecessary jargon
Structure your answers with subheadings that map to the question components
Use bullet points for key information
Ensure each paragraph addresses a single clear point
Have someone outside your technical team review for clarity
AI-powered tools like Grant Hero can help identify readability issues before submission, ensuring your application communicates clearly to assessors.
How to Increase Your Chances of Success
Beyond avoiding common mistakes, there are proactive steps you can take to strengthen your application:
1. Start Early
The most successful applications typically go through multiple drafts and revisions. Begin at least 4-6 weeks before the deadline to give yourself ample time for refinement.
2. Seek Objective Feedback
Have colleagues or external advisors review your application with fresh eyes. Expert review services connect you with specialists who understand what assessors are looking for, providing targeted feedback at a fraction of the cost of traditional consultants.
3. Use Data to Strengthen Your Case
Back up assertions with credible market research, industry reports, and customer validation. Quantify benefits wherever possible to make your case more compelling.
4. Learn from Previous Feedback
If you've applied before, carefully address any feedback received in your new application. Show that you've listened and improved your approach.
5. Focus on Value for Money
Clearly articulate why funding is necessary and how it represents good value. Explain what would happen without grant funding and why alternative sources aren't suitable.
How You Can Use Tools to Streamline Your Grant Writing Process
Writing a strong grant application doesn't have to mean starting from scratch. Modern tools can help you:
Generate structured first drafts based on your company data
Receive instant feedback on how to improve your answers
Access templates for required appendices like risk registers and project plans
Get expert reviews at a fraction of traditional consultant costs
Export your application in the ready-to-submit format
Using grant writing automation tools like AI with human expertise allows you to create high-quality applications in less time and at a lower cost than traditional methods.
Final Thoughts: Turning Rejection into Success
If your application is unsuccessful, don't be discouraged. Many successful grant recipients only succeeded after multiple attempts. Most funders provide detailed feedback on rejected applications, use this to strengthen your next submission.
Remember that grant writing is a skill that improves with practice. Each application you write builds your understanding of what assessors are looking for and how to present your project effectively.
By avoiding the common mistakes outlined in this guide and following best practices for grant writing, you can significantly increase your chances of securing the funding your project deserves.
