R&D Tax Credit Eligibility
R&D Tax Credits are a UK Government incentive designed to encourage innovation by rewarding companies that invest in advancing science and technology. If your business meets the qualifying criteria, you can claim tax relief or cashback for eligible R&D activities. You can typically claim R&D relief if you meet these criteria:
You must be a UK registered company that is liable for Corporation Tax.
Your project aims to advance science or technology by going beyond routine improvements.
Your project tackles technical uncertainties that a competent professional in your field cannot easily resolve.
You use a systematic, structured process of research, design, testing and analysis to overcome those uncertainties.

Finance Manager | Kudos Blends
Reach out to the experts! Even though we had claimed previously, and had a rough idea of what we could claim, we were blown away by the actual scope of what the claim could be and what was required.
Paul Speirs
Managing Director | Toolrite
Over the last few years we have been building a new breed of machinery for the new business start-up/sub-contract sector.
Our project was innovative due to its simplicity and tailored nature towards a mid-market entry point. One of the major benefits of our R&D claim was that it opened the door to new claim possibilities.
Michael Rosam
Founder | Quix
Whilst most founders in the technology space should realise that the R&D claim has the potential to be the highest ROI of any time spent across a year, the reality is that finding the time to prepare the claim and ensure robustness just doesn’t materialise. Leyton drove this end-to-end process with our technical leads and accounting partners ensuring that my time was only leveraged for context, confirmation of narrative and appreciation of the level of technical involvement.
