Understanding Pre-Seed and Seed Funding: SEIS vs EIS Rounds in the UK

Jumpstart Your Venture with Pre-Seed SEIS

Getting that first cheque in the door can feel like magic. Yet, for many UK founders, pre-seed SEIS is more than just a cash injection—it’s a lifeline wrapped in tax perks. With the Seed Enterprise Investment Scheme (SEIS), investors get significant relief, and founders gain the fuel to transform an idea into a prototype, hire the right talent, and build those crucial first sales loops.

This article walks you through the journey from pre-seed to seed, breaking down how SEIS rounds compare with later Enterprise Investment Scheme (EIS) rounds. You’ll learn the key differences, the steps to apply, and why Oriel IPO’s commission-free marketplace makes navigating pre-seed SEIS so much simpler. pre-seed SEIS: Revolutionizing Investment Opportunities in the UK

What Is SEIS and Why It Matters

Before diving into rounds, let’s unpack SEIS:

  • Government-backed Relief
    Investors can claim up to 50% income tax relief on investments up to £100,000 per tax year.
  • Capital Gains Exemption
    Any profit from SEIS shares held for at least three years is free from capital gains tax.
  • Loss Relief
    If the startup fails, investors can offset losses against income tax.

By using SEIS, early backers feel more secure, making them more likely to write that first cheque. And that’s the sweet spot for a pre-seed SEIS round: small sums, big impact.

Pre-Seed Round Explained

The pre-seed stage is where you move from sketching ideas on a napkin to a tangible prototype:

  • Objective: Validate your concept.
  • Product Stage: Mock-ups, proof of concept, minimum viable product (MVP).
  • Typical Round Size: £50k–£250k under SEIS.
  • Investors: Angels, accelerators, friends and family, public grants.

At this stage, you’re not expected to be generating revenue. You’re expected to show promise, a roadmap, and the team that can execute.

Seed Round vs Pre-Seed SEIS Round

Once you’ve proved the MVP works, you step up to the seed round. Here’s how seed and pre-seed SEIS differ:

Aspect Pre-Seed SEIS Seed Round
Focus Idea validation, prototype Market launch, user growth
Round Size £50k–£250k £250k–£1.5m
Tax Relief Up to 50% income tax relief (SEIS) 30% income tax relief (EIS) for amounts up to £1m
Use of Funds Team hires, POC, early traction Marketing, scaling ops, product refinement
Lead Investors Business angels, accelerators Early-stage VCs, angel syndicates

While both rounds aim to prove your model, pre-seed SEIS is laser-focused on rapid validation with lightweight teams. It’s the stepping stone to a larger, often EIS-backed, seed or Series A.

EIS Rounds: Scaling Beyond Seed

After seed, many firms look to the Enterprise Investment Scheme (EIS). Key perks of EIS:

  • 30% Income Tax Relief on investments up to £1m (or £2m for knowledge-intensive companies).
  • Capital Gains Deferral when reinvesting gains into EIS shares.
  • Loss Relief similar to SEIS but at 30%.

EIS is built for scaling. You’ve proved product-market fit, you’re generating revenue, and you need £1m–£5m to ramp up marketing, expand the team, and enter new territories. The tax incentives draw in larger VC funds, and that’s often your gateway to a Series A or B.
