Approach and focus
GG R&D Tax Advisory Limited is a specialist practice focused on the preparation and review of robust, well-evidenced R&D tax credit claims.
The approach is engineering-led and compliance-first, with a strong emphasis on evidence quality, technical accuracy, and alignment with current HMRC expectations.
Work typically involves structured technical discussions with client stakeholders, careful assessment against DSIT guidelines, and the preparation of clear, well-reasoned technical narratives intended to support HMRC review.
The practice combines experience gained within larger advisory firms with the responsiveness and continuity of a specialist independent practice. This enables a direct and consistent working relationship throughout an engagement whilst maintaining a strong focus on technical quality, professional scepticism and evidential robustness.
The firm operates in line with established professional standards, including Professional Conduct in Relation to Taxation (PCRT), with a focus on proportionality, clarity, and robustness in all outputs.
