SEIS accountants
in Cambridge

Cambridge is the UK's deepest deeptech and life-sciences SEIS / EIS market by sector concentration, even though the headcount is small. The University of Cambridge spinout pipeline (Cambridge Enterprise) and the Cambridge Cluster's biotech, AI, quantum, and silicon-IP companies produce a steady flow of SEIS-stage incorporations. The local angel base (Cambridge Angels, Martlet Capital, Amadeus Capital Partners' early-stage activity, Cambridge Innovation Capital) is unusually sophisticated and expects SEIS / EIS paperwork already in hand at first investor conversation.

The dominant SEIS specialism angle in Cambridge is knowledge-intensive company (KIC) status. Cambridge spinouts are R&D-heavy by nature and often qualify for the KIC variant of EIS that doubles the annual cap to £10m and extends the commercial-sale window from 7 to 10 years. The KIC qualification is documentary (R&D spend percentage thresholds, qualifying staff or IP-creation tests) and the founder needs an accountant who has filed multiple KIC assessments rather than reading the criteria for the first time.

EIS funds with a deeptech mandate (Octopus Ventures Future Generations, Parkwalk, IQ Capital, Cambridge Innovation Capital) are particularly active in this catchment. They expect EIS advance assurance plus KIC qualification documented as part of the diligence pack, not produced reactively post-term-sheet.

The Cambridge SEIS engagement profile skews longer than London: a typical sequence is SEIS round 12-18 months after incorporation, EIS extension 18-30 months later as the company scales, then a KIC-qualified larger EIS round around series A. Each transition needs the qualifying tests re-verified and the cap table maintained in a way that survives institutional VC diligence.

Cambridge specialists in our network have a deep KIC caseload — they have filed dozens of knowledge-intensive assessments and know which evidentiary patterns HMRC's Venture Capital Reliefs team accepts versus pushes back on. This expertise is rare; even competent SEIS practices outside the deeptech belt have rarely had to assemble a KIC application.

The Cambridge Enterprise spinout-licence interaction with SEIS share issues is the other local specialism. Where a company is built around exclusively-licensed university IP, the cap table needs to accommodate the licence terms, the founder equity, and the SEIS investor shares cleanly without breaching the SEIS independence test or compromising the IP arrangement. Specialist accountants in our Cambridge network routinely structure these.
