An R&D tax credit loan is finance that lets a UK company borrow against the value of its R&D tax credit claim before HMRC pays it. Rather than waiting months for the claim to be processed, you receive the cash now and repay the loan when the credit lands.
At SPRK Capital this product is our R&D Advance Loan. You draw up to 80% of your estimated claim, with no cash paid upfront, and the loan is repaid from your HMRC payment — so it works alongside your other funding solutions rather than competing with them.
Most R&D claims take several months to clear, and tighter HMRC compliance checks have made timelines less predictable. An R&D tax credit loan closes that gap: you turn a future receivable into working capital today, keeping R&D, hiring and growth on schedule instead of paused while you wait. The funding works for claims under the merged RDEC scheme and for loss-making R&D-intensive SMEs claiming under ERIS.
We advance up to 80% of your estimated R&D tax credit. The exact figure depends on the size and stage of your claim, your company’s circumstances and the strength of the underlying R&D. Keeping the loan-to-value conservative leaves built-in headroom between what you borrow and what HMRC is expected to pay. When HMRC pays, you retain the balance between the loan amount and the tax credit receipt.
The application is online and our credit and R&D technical teams assess submissions quickly. Once approved, funds are released the same day you sign under one set of standardised documents.
The loan is made to your company and secured by a first-ranking debenture, so you remain responsible for repayment if HMRC reduces or delays the credit. Our conservative advance rate is designed to absorb a reasonable shortfall, and because there are no early repayment fees you can settle from other sources at no extra cost. We’ll always work the position through with you.

SPRK are specialists in R&D finance, and we’re here to help you get the most from every pound spent on R&D.
What is an R&D Advance Loan?
An R&D (Research and Development) Advance Loan lets you borrow against your expected HMRC R&D tax credit before HMRC pays it. Companies can wait over 15 months from the start of R&D expenditure to receiving the credit. SPRK advances funds against your expected claim at any point in the financial year, so you can reinvest without waiting or gain certainty in your cashflow.
How do I qualify for an R&D tax credit loan?
Your business must invest in research and development that advances science or technology. SPRK requires you to work with a SPRK Approved Advisor, or to have your R&D tax calculations reviewed by one, to ensure your claim is accurately prepared. You also need at least three months’ cash runway and must not be reliant on unconfirmed equity raises at the time of application. Profitability is not a requirement, SPRK regularly lends to loss-making and pre-revenue companies.
How much can I borrow against an R&D tax credit claim?
SPRK lends from £50,000 upwards against R&D tax credit claims. For an R&D Advance Loan, SPRK lends up to 80% of your expected tax credit. The exact amount depends on the nature of your claim and SPRK’s underwriting assessment.
What’s the difference between an R&D Advance and an R&D tax credit loan?
The terms are used interchangeably, both refer to borrowing against an expected R&D tax credit. At SPRK, the R&D Advance Loan is a short-term facility repaid directly from the HMRC payment.
When do I repay the R&D tax credit loan?
When HMRC pays your R&D tax credit, it goes directly to your company. This receipt is used to settle the outstanding principal and interest within 48 hrs. You retain any surplus. There are no interest payments during the loan term, interest is added to the principal and settled at the end. The minimum loan term is three months.
What are the benefits of a SPRK R&D Tax Credit Loan?
SPRK’s Innovation Loans give companies investing in Research and Development the capital to scale their businesses. The facility is non-dilutive, requiring no equity and no personal guarantee. Companies can borrow up to 150% of their most recent or expected R&D Tax Credit, with a decision within 24-48 hours and funding typically the same day as signing. Loans run on a 36-month term with fixed, affordable monthly repayments. The facility is available to loss-making and pre-revenue companies.
What happens if HMRC does not pay my R&D tax credit?
If HMRC reduces or declines your R&D tax credit you are still liable for the loan. The R&D Tax Credit Loan is a secured loan, in these cases SPRK will work with companies to find an affordable repayment solution.
