A Guide for SMEs and Partners
Innovate UK’s Innovation Loans are designed to help businesses at the late stages of R&D with strong commercial potential.

Understanding the Loan Structure: The Three key phases
Innovation loans are structured into three distinct phases, outlined in the image below.
Security and Guarantees
One big advantage of Innovation Loans is that they do not require personal guarantees from business owners.
They are instead secured against company assets (via a mortgage debenture), meaning there is no personal liability for founders, directors or shareholders. They are also in subordination to commercial lenders to facilitate additional funding rounds.

Applying for an Innovation Loan involves a structured process to assess both the innovation potential and financial viability of the applicant. The process to apply is as follows:
- Create an account on the Innovate UK Funding Service.
- Submit business and financial details, including credit history and revenue forecasts.
- Describe your innovation project, detailing its commercial potential.
- Assessment by experts, including technical assessors and financial reviewers.
- Loan offer and agreement signing if successful.
The next deadlines for the Innovation Loan are: Round 19 on 5th March 2025; then Round 20 on 6th May 2025.
