Essential SEIS and EIS Investment Agreement Terms Every UK Founder Should Know

Introduction

Raising money through SEIS (Seed Enterprise Investment Scheme) and EIS (Enterprise Investment Scheme) can feel like navigating a labyrinth. The investment agreement terms you negotiate today shape your startup’s future. Get them wrong, and you’ll wrestle with dilution nightmares or tax relief complications. Get them right, and you’ll secure not just funds but peace of mind.

With the UK government backing SEIS/EIS through generous tax incentives, more founders are tapping into this scheme. Yet, the paperwork? Overwhelming. That’s where we come in. Oriel IPO is your partner in commission-free, curated, tax-efficient fundraising. We also offer educational tools and resources—like our AI-powered Maggie’s AutoBlog—for founders who want to maintain crystal-clear investor communications.

Let’s break down the investment agreement terms you absolutely need to understand.

Why SEIS & EIS Matter

Before diving into the legal maze, here’s the nutshell:

  • SEIS offers up to 50% income tax relief on investments up to £100k.
  • EIS offers up to 30% relief on investments up to £1m.
  • Both schemes come with capital gains tax exemptions, loss relief and carry-back provisions.

These perks attract angels like bees to honey. But to qualify, you and your investors must tick all the right boxes. The investment agreement terms set out those boxes.

Core Investment Agreement Terms

Every SEIS/EIS investment relies on a solid agreement. Think of it as a rulebook. Here are the must-know chapters in that book.

1. Names of the Parties

Yep, it sounds obvious. But naming your startup and your investor with full legal details is non-negotiable. It ties those individuals (or entities) to every clause in your agreement. No wiggle room.

2. Investment Amount

This clause states the exact sum your angel is wiring to your bank account. It also notes the currency and any instalment schedule. Why does it matter? Because your roadmap for hiring, R&D and marketing hinges on that figure.

3. Equity Stake

Equity is your founder currency. Hand over 5%? 20%? 51%? Your investment agreement terms will spell out:

  • Percentage of shares.
  • Type of shares (ordinary, preference, redeemable).
  • Impact on your existing cap table.

Pro tip: Avoid giving too much away too quickly. Dilution can come back to bite.

4. SEIS/EIS Compliance Clause

Neither you nor your investor wants HMRC knocking on the door. This clause assures that your company meets all eligibility criteria—age, gross assets, trading activities and no substantial existing shareholders. If you breach, tax relief is gone. Poof.

5. Tax Relief Triggers

Detailed here are the HMRC forms you’ll submit (SEIS1, EIS1), the timelines, and who’s responsible. These investment agreement terms often stipulate that you’ll repay investors if the relief is withdrawn.

6. Investor Rights & Responsibilities

Here’s where things get spicy. Your investor may ask for:

  • Voting rights.
  • Board observer status.
  • Information rights (monthly updates, quarterly financials).

Bullet-point clarity wins. Lay out what they get, and what you do in return.

7. Anti-Dilution and Protective Provisions

Imagine you raise another funding round at a lower valuation. Protective provisions shield your investor from excessive dilution. Anti-dilution can be:

  • Full ratchet.
  • Weighted average.

This section of the investment agreement terms can make or break your future rounds. Tread carefully.

8. Drag-Along & Tag-Along Rights

  • Drag-along: Majority shareholders can compel minority shareholders to sell if there’s an acquisition.
  • Tag-along: Minority shareholders can join if the majority sells.

These rights ensure fair treatment at exit. We all love fair.

9. Dispute Resolution

You hope never to use it, but you need a playbook for conflicts. Mediation? Arbitration? Court? This clause maps the path when things go south.

10. Exit Terms

What happens when you sell the company or wind up? Detail:

  • Share transfer mechanics.
  • Redemption rights.
  • Repayment order on insolvency.

Clarity here prevents messy endings.

Negotiating investment agreement terms can feel like chess. Here’s how to stay three moves ahead:

  • Start with a clear term sheet. Bullet points only.
  • Benchmark market standards—EIS norms, SEIS caps.
  • Know your BATNA (Best Alternative To a Negotiated Agreement). Walk away if terms are unfair.
  • Get legal advice—ideally from someone who eats SEIS/EIS for breakfast.
  • Use Oriel IPO’s educational resources to gather real-life examples and templates.
