Companies registered in London and the South East claimed almost half of the £8.2bn of research and development tax relief in 2024-25, according to HMRC statistics published on 29 September, prompting R&D software company innoscripta to suggest a higher rate of relief for R&D staff based elsewhere.
Firms with registered offices in London accounted for 30 per cent of the amount claimed and those in the South East for 19 per cent, a combined 49 per cent, the HMRC figures show. By number of claims, London made up 24 per cent and the South East 15 per cent.
The East of England ranked third, with 14 per cent of the amount claimed and 10 per cent of claims, according to HMRC. The three regions together accounted for 63 per cent of the value of relief claimed.
