Catalyst Solutions unveils a rebuilt platform to help companies navigate major shifts in R&D tax relief

LONDON, LONDON, UNITED KINGDOM, June 15, 2026 - As the UK overhauls the way R&D tax relief is claimed, the recent reforms have reshaped the process enough that the guidance of seasoned R&D tax consultants now carries real weight for firms of every size. Responding to that need, Catalyst Solutions, a practice with a presence in three international markets, has rolled out a rebuilt website that gives UK businesses clearer access to advice on claiming R&D tax incentives under HMRC's merged Research and Development Expenditure Credit scheme.

Applying to accounting periods that start on or after 1 April 2024, the merged RDEC scheme has redrawn the picture for companies that once claimed through separate routes. Previously, small and medium-sized enterprises and larger organisations pursued relief via distinct channels, each carrying its own rate and set of rules. By folding those channels into one relief, the merged scheme alters both how the credit is worked out and how the resulting benefit is taxed. In practice, this often leaves companies with a different net outcome once a claim is complete, alongside a much sharper need to get the underlying detail exactly right.

Across the refreshed platform, businesses will find thorough information on the reshaped relief landscape, spanning eligibility criteria, categories of qualifying expenditure, and the entire claims journey, so they can grasp what relief exists and how to secure it. The site also sets out the extra support open to loss-making, research-intensive small and medium-sized enterprises, which may qualify for a more generous rate when qualifying R&D accounts for a sizeable share of their total spend.

Alongside this, the website details how Catalyst Solutions assists businesses through each phase of a claim, from pinpointing qualifying activities and drafting technical narratives to dealing with HMRC when needed. Because HMRC has tightened its examination of claims over recent years, the firm puts strong focus on rigorous documentation and clear technical narratives that evidence the scientific or technological advance underpinning a project. Working as specialist R&D tax consultants, the team seeks to help businesses lodge compliant claims while lowering the likelihood of an enquiry.

Any UK business putting money into innovation can turn to the website to gauge whether its activities might qualify for R&D tax incentives and to learn what preparing a compliant claim involves. The material is designed to suit companies encountering the relief for the first time as well as longstanding claimants getting to grips with the revised rules.
