How to invest in EIS: routes, checks and practical steps

By EISInvestments.co.uk Editorial Team · Published 2026-10-25 · Last reviewed 2026-10-25

Short answer

You can invest in EIS directly in a single company, through an EIS fund or portfolio service, or via a crowdfunding platform or adviser. Before investing, check the company's EIS position, read the investment documents, understand the risks and consider professional advice.

Three ways to invest in EIS

Platforms and advisersOnline platforms or advisers arrange the investmentCheck whether the firm is FCA authorised and what protections apply

Compare structures in EIS schemes explained.

Step 1 — Decide whether EIS is appropriate

Consider how much of your wealth you could afford to lose entirely, how long you can lock money away, and whether you have enough UK income tax liability to use the relief. EIS is generally suitable only as a small part of a diversified portfolio.

Step 2 — Check the investment

  • Check the company on Companies House: incorporation date, directors, filed accounts and charges.
  • Ask for evidence of the EIS position, such as HMRC advance assurance, and understand its limits.
  • Read the information memorandum or pitch, the articles of association and the subscription agreement.
  • Understand the share class, valuation, use of funds, dilution and exit assumptions.
  • Find out who is promoting the investment and whether they are FCA authorised.

Step 3 — Complete investor categorisation

Firms promoting high-risk investments will usually ask you to confirm whether you are a high-net-worth, sophisticated or professional investor and to complete an appropriateness assessment. These are regulatory steps; they do not determine your entitlement to tax relief.

Step 4 — Subscribe and pay

Sign the subscription documents and pay the subscription in cash. Shares must be fully paid at issue. Keep copies of all documents.

Step 5 — Receive your EIS3 and claim relief

After the company has traded for four months and HMRC has approved its compliance statement, you will receive an EIS3. Use it to claim relief on your Self Assessment return. Claims must be made within five years of 31 January following the tax year in which the shares were issued.

Step 6 — Keep records and monitor

Keep your EIS3 and records of any gains deferred. Tell HMRC within 60 days if anything happens that means relief should be withdrawn.

Frequently asked questions

Is there a minimum investment for EIS?+

HMRC sets no minimum. Companies and funds set their own minimum subscriptions.

Do I need a financial adviser to invest in EIS?+

Not necessarily, but because EIS investments are high risk and tax relief depends on your circumstances, independent regulated advice is strongly recommended.
