We were introduced to RCK in 2023 by one of our existing clients who highly recommended their services. Over the past three years, we have trusted RCK to manage our R&D claims and have just completed our most recent submission. Their team are all consistently friendly, professional, and highly knowledgeable about our industry, which has made the entire process much smoother and far less stressful. From start to finish — even in what was a slightly more complex claim this year — RCK handled everything efficiently, minimising the time and effort required from our staff and avoiding hours of downtime gathering information. This year, Cassius managed our claim, and we cannot speak highly enough of him. His strong understanding of our industry ensured a quick turnaround and a seamless application process. We would highly recommend RCK to any business seeking expert guidance with their R&D claims.

We have worked with RCK Chartered Tax Advisors for a few years now, and their service continues to be nothing short of outstanding. Their support with our corporate tax credits has been invaluable, and the process is always handled with professionalism, clarity, and genuine care.

His attention to detail, responsiveness, and deep expertise have made what could have been a complex process feel smooth and stress-free.

CEO & Co-founder at Hyper
Working with RCK on our R&D tax claim was an excellent experience. They were able to extract maximum value from the process while staying fully within government guidelines, always acting with integrity, trust, and speed. They came across as true partners to the business, supportive, knowledgeable, reliable, and consistently delivered on their promises. Based on my experience with them in my capacity as interim CFO, I would not hesitate to recommend their services.

A step-by-step guide to making a capital allowance claim in the UK.
A Times-featured study, commissioned by RCK Partners and conducted by Censuswide, suggests that recent reforms to the UK's R&D tax relief scheme may have gone too far. The research found that measures introduced by HMRC to tackle abuse of the scheme are having unintended consequences for genuine innovators, with many businesses reporting that they have cancelled research initiatives, paused investment plans and reduced skilled headcount as a result of increased uncertainty surrounding the regime.
