Why repeat often submissions get rejected – and how to avoid ineligible applications.
Few things are more frustrating than spending weeks (or months) drafting an Innovate UK grant application, only to see it rejected before scoring begins. Sometimes, it is not because your idea isn’t strong but because your proposal isn’t “materially different” from something you’ve submitted before.
So what does being “materially different” actually mean from the perspective of Innovate UK, and how to avoid losing time to an eligibility technicality?
This article breaks down what Innovate UK considers materially different, the most common resubmission traps, and how to protect your next application from being rejected on a technicality.
How to avoid submitting an ineligible resubmission
To be materially different, your proposal needs to show clear changes in the scope, technical work, and innovation being delivered – not simply improvements in writing, partner structure, or costs.
Most materially different proposals demonstrate at least two of the following:
1. Different project scope – the problem, opportunity, or project focus has moved forward in a meaningful way – not just been reworded.
2. Different R&D activity – the technical work being proposed is genuinely new, rather than the same work with a revised plan. This may also include new outputs generated from the project.
3. Different innovation stage or application – for example 1) moving from feasibility to development (with clearly new technical objectives); 2) pivoting to a new market, or 3) shifting to a new technological approach that changes the core R&D challenge.
What does not count as materially different?
Innovate UK told us the following changes would not normally be enough on their own:
❌ Changing nothing but the project costs or financial profile
❌ Switching the research category alone (e.g., feasibility vs industrial research)
❌ Only changing project partners or consortium structure
❌ Updating your application solely based on assessor feedback
If in doubt
Innovate UK competitions typically include a contact point for eligibility queries, and many run a competition helpline. If you’re unsure whether your idea is materially different, it’s worth checking early, especially before investing time in a full proposal.
