The UK's most active angels are mostly networks, not named individuals. Beauhurst's August 2025 ranking puts Oxfordshire's OION first with 300 funding rounds since 2011, then Cambridge Angels with 298 and Equity Gap with 222. Tech Nation's June 2025 list puts SFC Capital first among early-stage investors, with 456 rounds in five years.
Search for "top UK angel investors" and you will find lists of famous names with no stated method. The better data is about groups. UK angels invest through networks, syndicates and EIS or SEIS funds, and the researchers who track deals, Beauhurst and Tech Nation, count rounds by group. This page uses those two datasets, says where each one is limited, and then covers what the individual-level evidence shows and how to pitch.
A note on my position. I'm an angel investor with 234 investments as of October 2026, ranked the #1 most active angel investor in 2024 by Lenny's Newsletter, which used Crunchbase data. That ranking is for the US, and nothing below comes from my own UK experience: it all comes from the pages linked.
Who are the most active angel networks in the UK?
Beauhurst's ranking of UK angel networks, published on 28 August 2025, orders groups by the number of rounds they took part in. Between 2011 and July 2025 Beauhurst tracked 3,636 fundraisings involving UK angel networks. Its top ten, with fundraisings and companies invested in as published:
Oxfordshire Investment Opportunity Network (OION): 300 fundraisings, 223 companies.
Cambridge Angels: 298 fundraisings, 170 companies.
Equity Gap: 222 fundraisings, 55 companies.
Minerva Business Angel Network: 189 fundraisings, 115 companies.
Archangels: 205 fundraisings, 38 companies.
Envestors: 189 fundraisings, 133 companies.
Wealth Club: 187 fundraisings, 77 companies.
24Haymarket: 162 fundraisings, 70 companies.
TRICAPITAL: 140 fundraisings, 43 companies.
Kelvin Capital: 131 fundraisings, 39 companies.
Two cautions from the source itself. Beauhurst counts only rounds where network involvement was confirmed through press announcements or private disclosure, and says many groups operate quietly, so true volumes are likely higher. Also, the table's order doesn't follow the fundraising counts exactly (Minerva is listed fourth with 189, Archangels fifth with 205). Beauhurst's order and figures are reproduced as published.
Equity Gap says a later Beauhurst report covering 15 years of UK angel investment ranked it third in the UK and first in Scotland by deal volume and deal value, which is consistent with the third place above.
Which investors did the most early-stage rounds?
Tech Nation's 30 most active UK startup investors, dated 23 June 2025, ranks by the number of VC rounds each investor took part in over the past five years. The early-stage (seed and Series A) top five:
SFC Capital (labelled angel and VC): 456 rounds.
Mercia Asset Management: 165.
Scottish Enterprise Growth Investments: 139.
Fuel Ventures: 132.
Seedcamp: 127.
SFC Capital is the outlier. It describes itself on its own site as operating the UK's leading SEIS fund, and says its Angel Fund is for professional investors, high-net-worth individuals or certified sophisticated investors. At 456 rounds in five years it is a high-volume investor, so its count isn't comparable with that of a fund making a few large investments. Tech Nation's page doesn't say which dataset it used.
What about individual UK angels?
No free, dated ranking of named individuals is cited here. The closest is the Founders Forum's UK Angels 100, published in April 2023 with Beauhurst and Founders Factory, which describes the 100 most active angels in UK companies. The list itself is behind a download form. The page summarises its findings: almost half of the 100 are current or former founders, they invest most in AI, B2B SaaS, deep tech and fintech, and the vast majority are white men. It names Andy Phillipps (Booking.com), Pam Garside (Cambridge Angels), Timothy Armoo (Fanbytes) and Tom Blomfield (Monzo) as interviewees for the report, not as list entries.
The gender point has a UK-specific data source: Beauhurst's 2025 research puts women at 14.1% of the UK angel population. The women angel investors article covers that in more depth.
If you want individual angels, the practical route is not a list. Use the groups above, whose members are individuals, and ask them for introductions.
How do the leading networks say they work?
Cambridge Angels says it has been investing since 2001, supporting more than 150 companies. It caps membership at 65, charges companies no pitching or carry fees, and offers free office hours with an experienced investor.
OION is run by Oxford Innovation Finance, which describes the network as one of the oldest, largest and most active in the UK. It focuses on early-stage science and technology companies and has a "Raise with us" route for companies.
SFC Capital works through SEIS and EIS funds, which is why UK angel activity often runs through tax-advantaged vehicles. The government's SEIS guidance says the scheme offers tax reliefs to individual investors who buy new shares, and that a company can receive a maximum of £250,000 through it.
How should you pitch UK angels?
Match the group to your region and sector. OION leans science and technology, and others lean regional. Pick two or three groups rather than all ten.
Check SEIS and EIS eligibility early. Many UK angels expect it, and the rules cap how much a company can raise, among other conditions.
Use the free routes first. Cambridge Angels' office hours and the UKBAA directory and regional angel hubs cost nothing to browse.
Prepare for a group process. Screening, a pitch meeting and diligence are normal, as described in how to join an angel group or syndicate and angel investor networks in 2026.
Plan the round, not the person. The guide to finding angel investors and the data on how much angels invest help you size it.

Frequently Asked Questions
Q:Who is the most active angel group in the UK?
Per Beauhurst's August 2025 ranking, the Oxfordshire Investment Opportunity Network is first with 300 fundraisings tracked between 2011 and July 2025. Cambridge Angels is second with 298. Beauhurst says the true figures are likely higher because many groups don't publicise deals.
Q:Is there a ranked list of individual UK angel investors?
No free, dated one is cited here. The Founders Forum's UK Angels 100 (2023) covers the 100 most active angels, but its names sit behind a download form. Tech Nation's 2025 list covers firms and groups, not individuals.
Q:Do UK angels need to be accredited like US angels?
The UK uses different categories, such as high net worth and sophisticated investor. SFC Capital's site, for example, says its Angel Fund is intended for professional investors, high net worth individuals or certified sophisticated investors. Check the rules for any scheme you join.
Q:How much do UK angels invest?
The sources above don't give a typical check size, and the networks decide individually. Cambridge Angels' site doesn't state one, for example. Ask each group for its range before pitching.
Q:What are SEIS and EIS?
They are UK tax-relief schemes that encourage individuals to invest in early-stage companies. Under the SEIS guidance on gov.uk, a company can receive up to £250,000 through it, and relief can be withdrawn if the rules aren't followed. Founders should check eligibility with an adviser before raising.
