In September 2024, HMRC raided offices in Norwich city centre on the same day that 11 people, including tax agents, were arrested across the country on suspicion of R&D tax relief fraud. Officers from the tax office executed warrants at the companies Green Jellyfish and Kirby & Haslam at the Union Building on Rose Lane. However, the firm was accused of targeting and submitting claims for companies which were ineligible for R&D tax relief.
