R&D Tax Expertise & AI that puts integrity at the frontier.

Most R&D firms sell senior expertise then hand delivery to juniors, creating inconsistent advice and weaker claims. Others rely on checkbox SaaS that HMRC has learned to scrutinise. Unity is senior-led and AI-centric: the people who advise you are the people who do the work, accelerated by purpose-built technology. It's a new model for R&D consulting built around quality, not leverage.

Some of the most experienced former senior leadership professionals across the Big Four, with decades of experience in the sector. Unity was founded by Marissa Thomas, former Managing Partner and COO of PwC UK who previously led the UK Deals and Tax businesses, and Steve Varley, former UK Chair of EY and Global Vice-Chair Sustainability, who now chairs DWF Group.

No. Our technology is purpose-built for R&D tax, using frontier AI capabilities while remaining model-agnostic so we're never locked into a single provider. Under the hood, a complex orchestration of AI agents, each trained with expertise derived from senior practitioners with decades of experience, work in concert across R&D tax, science and technology domains. Everything is built to the highest security standards. The AI accelerates our advisors, it doesn't replace them. Every output is reviewed by a specialist before it goes anywhere near your claim.

Always. AI handles the heavy lifting: document analysis, technical narrative drafting, consistency checks. But a senior advisor signs off on every claim. We use AI to be faster and more thorough, not to cut corners.

Often we find that long-standing claims have drifted. We'll benchmark your existing claims against current HMRC scrutiny levels and typically identify both missed eligible work and areas of over-claiming risk. A fresh pair of eyes, backed by AI analysis, almost always finds something.

None. Our approach is designed to autonomise the workload across your engineers and scientists, with deep guidance throughout the process. AI does the heavy lifting to gather details, supported by our technology and experts working in tandem. Not weeks and months of interviews pulling people off delivery.

We stand behind every claim we prepare. If HMRC opens an enquiry, we handle the full defence at no extra cost, including all correspondence, technical arguments, and meetings with inspectors. Our claims are built to withstand scrutiny from day one.

Typically 3-4 weeks for a standard claim, once timelines are agreed with the client. Our AI accelerates the parts that traditionally drag: document review, narrative drafting, eligibility mapping.
