15 Best UK Angel Investing Platforms with SEIS/EIS Benefits in 2025

Why SEIS/EIS Matters

If you’re scouting for the best business angel platform, you’ve seen the acronyms SEIS and EIS everywhere.
Here’s why they’re vital:

  • Tax breaks: Up to 50% income tax relief on SEIS, 30% on EIS.
  • Loss relief: Shield your downside if a startup doesn’t pan out.
  • Capital gains exemption: No CGT on profits after three years.

That’s why every savvy investor hunts for a business angel platform with SEIS/EIS approval.

How to Choose the Right Business Angel Platform

Not all platforms are created equal. To pick yours, ask:

  1. What’s the minimum ticket?
  2. Are deals pooled into an SPV?
  3. How deep is their due diligence?
  4. What support do they offer to founders?
  5. Are they regulated (FCA, ECSPR), or non-regulated?

Armed with these, you’ll spot the standout business angel platform from the sea of options.
