Unlimited Grants Programme
How the programme works
GrantUp scopes eligible opportunities, drafts and reviews your applications across the competitions marked as included in our grant directory (the Supported Portfolio). You approve all content and remain responsible for submission and funder deadlines.
- I
Identify
We scope eligible opportunities from the Supported Portfolio against your roadmap and readiness.
- P
Prepare
We draft and review your applications, building assessor-ready narratives, budgets and project plans.
- S
Strengthen
Internal review rounds, feedback loops and submission support lift your score before the deadline.
One monthly fee, a rolling portfolio of bids
Unlimited is a paid six month retainer. Applications we progress within the Supported Portfolio carry no separate per bid writing fee, so the cost of going after several competitions is predictable rather than cumulative. A success fee applies on award. It suits UK businesses with an active R&D roadmap and the match funding in place for the share of project costs grants do not cover.

We also support other UK and European grants on request, so if the competition you have in mind is not listed here, ask us and we will look at it with you.
