Introduction: Mapping Your Path as a SEIS and EIS Investor
If you’re one of those UK high net worth investors, you know that diving into startup funding under SEIS and EIS schemes can feel like entering a maze. Four distinct investor categories each come with their own eligibility rules and paperwork. Which box do you tick? And how do you prove it? We’ll cut through the jargon and show you exactly what you need to make your declarations, claim your tax relief, and back the next big idea without faff.
At Oriel IPO, we believe clarity is power. Our commission-free marketplace and intuitive investor tools let you focus on spotting great opportunities rather than wrestling with forms. Revolutionising Investment Opportunities for UK high net worth investors, we bring everything into one platform. From self-certified statements to EIS3 certificates, you’ll find it here.
Understanding SEIS and EIS: A Quick Overview
The Seed Enterprise Investment Scheme (SEIS) and the Enterprise Investment Scheme (EIS) let investors pocket serious tax incentives. With SEIS, you can claim up to 50% income tax relief on investments up to £100,000 a tax year. EIS gives you 30% relief on up to £1 million. There’s also capital gains tax exemption on disposal, and a way to defer gains from other assets.
But it’s not one-size-fits-all. The rules ask that you qualify under one of several investor types. You must provide proof before a company can issue you the SEIS1 or EIS3 certificate, which is your ticket to tax breaks. Get the declaration wrong and you risk losing the relief — or worse, running foul of the rules. Let’s break down the four main categories you’ll encounter.
4 Investor Categories Explained
1. Self-Certified High Net Worth Individual
Think you’re rich enough? If you have:
- Net assets over £250,000 (excluding your primary home, pension, and life insurance), or
- An annual income exceeding £100,000,
you can self-certify. It’s as simple as ticking a box on a statutory declaration. No solicitor certificate needed. You just confirm you meet the thresholds and you’re good to go.
Documentation guide:
- Complete the self-certified high net worth box on your investor statement.
- Keep proof of your assets or income (bank statements, investment valuations).
- Sign, date, and return to the company.

2. Certified High Net Worth Individual
For extra assurance, some startups prefer a certificate from an authorised person. You’ll need:
- A statement from a UK-based solicitor, accountant, or financial adviser.
- Confirmation you meet the same asset or income criteria.
This certificate stands in place of self-certification. It’s ideal if you want a watertight audit trail or if the company policy requires it.
Documentation guide:
- Obtain an authorised certificate under section 48A.
- Attach it to your investor declaration.
- Submit to the issuing company before they file your SEIS1/EIS3.

3. Self-Certified Sophisticated Investor
You don’t need to be ultra-rich to back startups. If you can show:
- Significant experience in venture finance, or
- Membership of an angel network or regulated investment body, or
- A track record of making multiple share investments,
you qualify as a sophisticated investor. Again, it’s a self-declaration but with a focus on your expertise.
Documentation guide:
- Tick the self-certified sophisticated investor section.
- Detail your experience (dates, amounts, platforms).
- Sign the declaration and supply supporting evidence on request.

4. VCTs and Other Institutional Investors
Venture Capital Trusts (VCTs) and venture capital funds often invest under the EIS umbrella. They have:
- Formal approvals from HMRC, and
- A pool of investors backing their fund structure.
Since they’re regulated, they need to provide an HMRC-issued EIS notice or an equivalent fund approval.
Documentation guide:
- Present your fund’s HMRC approval letter.
- Ensure the fund manager completes the EIS3 process.
- Share the EIS3 certificates with portfolio companies.
