With over 12 years of experience, we have identified over a quarter of a billion pounds in tax benefit for our clients to date – that’s an average client benefit of £60k!


Headquartered in Manchester, with offices in London, Glasgow and the Channel Islands, we have a team of over 100 in-house experts including Surveyors, Tax Technicians, Accountants, Report Writers and Case Managers.


We understand that tax relief can be complex, so we break down the claims process for you - all you need to do is provide us with some details, and we'll take care of the rest! There are no complicated forms to fill out, no legal language to unpick, and no tax law to get your head around.


We are trusted partners with many of the UK's top accountants, solicitors, the Law Society, ICAEW and IFA amongst other industry bodies. So far, we've helped thousands of businesses claim back money from HMRC.


We are extremely proud that our Quality Management System is ISO 9001:2015 certified which demonstrates our commitment to delivering quality in the work we do.

  • We sit on the HMRC Research & Development Consultative Committee, allowing timely discussions with HMRC and our peers in respect of the R&D tax relief legislation and current working practices and interpretations.
  • Our fees are contingency-based, meaning there are no risks in proceeding with our services.
