Understand UK angel investors, network applications and the limits of SEIS and EIS, then prepare a clear funding case and adviser questions.

Raising from angels means finding individuals able to assess and fund your business, then agreeing an investment through an appropriate process. A network may provide an application route and a syndicate may bring several people into the same round. SEIS and EIS can matter to qualifying investors, but neither is an endorsement of your business or a guarantee of relief. Prepare the business case, understand who makes the decision and ask qualified advisers about the company and investor conditions.
Key takeaways
- An angel, a network and a syndicate describe different things.
- Separate an investor's annual tax-relief limit from a company's scheme limit.
- Advance assurance concerns specified conditions, not investment quality or every investor's eligibility.
An angel invests their own money. A network can help founders reach members and organise applications, but it should not automatically be described as a pooled fund. A syndicate brings participants together around an investment arrangement whose details need checking.
Consider a hypothetical round involving four individuals. One may coordinate questions, another may have relevant operating experience and each may make their own decision. The fact that they share a network does not establish that one can commit the others.
Ask who screens applications, who decides and what any stated funding amount represents. Is it an individual's possible cheque, a total round requirement or an amount previously assembled by several members? Those figures answer different questions.
The funding stage map explains why angel investment is not a compulsory stage before every pre-seed round.
A tax scheme does not answer whether customers want the product or whether the spending plan is sound. Explain those parts of the business on their own.
For example, a hypothetical company testing scheduling software for clinics should explain who uses the prototype, what has been learned and what the round would test next. “We expect to qualify for SEIS” would not replace that account, even if an adviser had reviewed the proposal.
Then explain the scheme position accurately and separately. If an application is being prepared, say that. If advance assurance has been received, describe the scope and date rather than saying HMRC has approved the company as an investment.
This guide is general education, not personalised tax or investment advice. Ask a qualified accountant or lawyer about your proposed investment and current rules before making eligibility claims.
HMRC's investor guidance, checked on 29 October 2026, describes income-tax relief of 50% for qualifying SEIS investment, with a £200,000 annual investor limit. It describes EIS relief of 30%, normally with a £1 million annual limit, or £2 million where at least £1 million is invested in knowledge-intensive companies. Conditions apply to the investor, company and investment.
These figures are not a guaranteed saving for any individual or a calculation of the investment's net risk. An investor's circumstances and tax liability matter. Don't promise a fixed return or describe the investment as protected from loss.
The company's SEIS cap is a different figure. HMRC's company guidance states a maximum of £250,000. Its selected conditions include gross assets no greater than £350,000 and fewer than 25 full-time equivalent employees. This paragraph is not the complete eligibility test.
HMRC explains advance assurance as an indication that a proposed investment may qualify under the relevant scheme. It does not tell you whether an individual investor meets their conditions.
Imagine a hypothetical founder who has received a letter based on a particular company proposal. It would be inaccurate to turn that into “every person joining this round gets relief”. Changes to the proposal and investor circumstances need proper checking.
Keep the letter and the information supplied with it organised for your adviser and relevant investor questions. Ask what happens if the structure, business or share issue changes. Do not use an outdated summary copied from another founder's application.
The goal is to state the position you can support. An uncertainty marked clearly is better than reassurance you are not qualified to give.
Use a network's own entrepreneur page to check its scope and process. A directory entry or a local address is not enough to establish fit.
For one concrete example, Cambridge Angels' entrepreneur page, checked on 29 October 2026, describes an open application policy and criteria for the businesses it considers. Read the current page before applying; it is a network-specific route, not a universal rule for UK angels.
A hypothetical founder can put the stated criteria beside the company's actual position. If a requirement is unclear, mark the question rather than assuming the network will overlook it. Follow the published route and prepare the requested material.
The Cambridge Angels Teardown reads three actual financings and distinguishes network participation from a member’s individual cheque.
A warm introduction may be useful in some circumstances, but a published application route lets you begin the research and preparation without one. It does not guarantee a pitch invitation or member participation.
Suppose a hypothetical company is seeking £300,000 and three people discuss investing £100,000, £75,000 and £50,000. Those amounts total £225,000, leaving £75,000 of the target unfilled. They are an arithmetic example, not typical angel cheque sizes.
Now distinguish discussion from actual commitment. If one amount is conditional on another investor joining, record the condition. If documents remain under review, don't show the entire £225,000 as received cash in the operating forecast.
Ask who coordinates the process, what each participant needs to decide and what the company must complete. A lead contact can simplify communication, but the actual authority and arrangements should be confirmed with advisers.
This prevents the group label from hiding important differences between the participants. Your tracker should make the next step and remaining uncertainty visible.
Gather a concise business description, evidence about the customer and product, a use-of-funds plan and a cash forecast. Keep legal and ownership records available for the appropriate diligence stage.
For the hypothetical clinic software company, an interested tester, a signed pilot and a paying customer are distinct forms of evidence. Explain which you have, with dates and definitions. A product demonstration should match what you describe in the deck.
The seed round preparation guide shows how to distinguish observations, assumptions and future plans. Use the same discipline whether you approach an individual or a fund.
Avoid sharing personal customer data in an initial pitch. Provide relevant summaries and agree an appropriate process for sensitive documents rather than uploading everything to an open folder.
Prepare specific questions about the actual proposed round. An adviser can give a more useful answer when the company facts and intended structure are clear.
A hypothetical question list could include whether the company and proposed shares meet the relevant scheme conditions, what information investors need, how changes affect an existing assurance position, and what filings or ongoing obligations may apply. These are prompts for advice, not a complete legal checklist.
Keep a record of which answers came from your adviser and when. A network member's experience of a different company is not a substitute for advice about yours. Nor does a phrase in an investor email establish a tax conclusion.
If a fact is unresolved, put it in the materials as unresolved and agree the next action. You can still explain the business without promising relief.
Persephone, the investor-matching tool for UK and EU founders, helps organise investor research and draft relevant first emails. You remain responsible for the business claims and use qualified advisers for legal and tax decisions.
