The Critical Role of UK Startup Funding Sources

Picking the right funding source is more than just chasing money. It shapes your ownership, your growth speed, and even the advice you get along the way. In the UK alone, government-backed schemes like SEIS and EIS have unlocked over £1 billion in investments—but only for those who know how to play by the rules. And that’s where a commission-free, subscription-based investment marketplace can transform the game.

By combining clear tax advantages, expert vetting, and direct access to angel investors, Oriel IPO smooths out many of the bumps in a typical fundraising journey. Later, we’ll walk you through practical steps for getting funded, plus real-world testimonials from founders who’ve navigated this landscape successfully.


1. Angel Investors: The Personal Touch

Angel investors are high-net-worth individuals who back early-stage ventures in exchange for equity. Think of them as your first champions. They often invest between £10,000 and £250,000, bringing not only capital but connections and mentorship.

Why Angels Matter

  • Quick turnaround. Angels can move faster than big funds.
  • Hands-on support. Many have been entrepreneurs themselves.
  • Flexible terms. You negotiate directly, avoiding rigid VC term sheets.

Finding and Approaching Angels

  1. Craft a concise pitch. Highlight your problem-solution fit.
  2. Network at industry events. Meet angels in person or online.
  3. Leverage curated platforms. A vetted marketplace filters out mismatches.

That’s where Oriel IPO shines. Their subscription-based model means no commission bites into your equity. Instead, you pay a transparent fee and retain more ownership. Plus, each startup is screened for SEIS/EIS eligibility, boosting investor confidence.


2. Government-Backed Schemes: SEIS & EIS Unpacked

The UK’s Seed Enterprise Investment Scheme (SEIS) and Enterprise Investment Scheme (EIS) are designed to de-risk early-stage investing with juicy tax reliefs. Let’s break them down.

SEIS: Seed Enterprise Investment Scheme

  • Income tax relief: 50% of the investment (up to £100k per tax year).
  • Capital gains exemption: No CGT on SEIS shares if held for three years.
  • Loss relief: Offset losses against income tax.

Eligible companies are seed-stage, with fewer than 25 employees and assets under £200k. This scheme is tailor-made for pre-revenue startups.

EIS: Enterprise Investment Scheme

  • Income tax relief: 30% of the investment (up to £1m per tax year, or £2m if at least £1m goes into knowledge-intensive companies).
  • No CGT on gains after three years.
  • Loss relief and CGT deferral options.

EIS applies to slightly larger startups—up to 250 employees and assets under £15m. It’s perfect for ventures with some traction and clear growth potential.

How to Qualify

  • Maintain an eligible business activity.
  • Issue shares that are fully paid in cash.
  • Provide detailed investor certificates (SEIS1/EIS1).

Navigating red tape can be daunting. That’s another win for Oriel IPO: they provide guides, webinars and checklists, making sure your application is shipshape before you pitch.
