Should I apply for SEIS before EIS?

Recommended route
SEIS gives the most generous investor relief but is capped by company age, gross assets and lifetime SEIS receipts. Founders normally raise SEIS first to anchor early angels, then move to EIS for the rest of the round. Getting the sequence wrong can blow the SEIS allowance.
Alternative routes
Where the primary recommendation is not the right fit, these are the programmes most commonly considered alongside it.
- Seed Enterprise Investment Scheme (SEIS)
tax_incentive · Up to £250k raised
Common mistakes
- Starting with the largest scheme rather than the highest-fit scheme.
- Treating funding as a one-off project rather than a 24-month strategy.
- Underestimating the documentation effort: prior trading, prior R&D, finance pack.
- Missing the interaction between grant income and downstream R&D tax relief.
- Engaging a contingent-fee broker before checking whether the scheme is broker-eligible.
- Self-selecting out of a programme based on an optimistic read of eligibility.
Decision checklist
- Confirm your business stage, region and headcount against scheme thresholds.
- Map the next 24 months of funding need before applying to any one programme.
- Identify the official source for each programme on your shortlist.
- Quantify match-funding and staged-drawdown impact on cashflow.
- Check subsidy-control / de minimis ceilings across stacked awards.
- Model the interaction with R&D tax relief on subsidised costs.
- Decide whether the assessment timeline fits your delivery plan.
- Schedule the application in the calendar before committing operator hours.

- Can I apply to more than one of these programmes?
