United Kingdom
The best-regulated market — with one blind spot
The UK proves comply-or-explain works: 40% women on FTSE 350 boards achieved, ethnic-minority representation tracked, near-universal disclosure. Everything the FCA measures has moved. LGBTQ+ is the only dimension the framework omits — the UK already counts; it just doesn’t count everyone yet.
What this market requires
UK-listed companies report annually, comply-or-explain, against hard diversity targets with standardized data tables — a regime that survived the biggest listing-rules rewrite in 30 years intact. It mandates numbers for gender and ethnicity. It asks nothing about LGBTQ+ identity.
UK Listing Rules: targets and tables
Under UKLR 6.6.6R(9)–(11) (formerly LR 9.8.6R), listed companies must report annually against three targets: at least 40% women on the board; at least one woman in a senior board position (Chair, CEO, SID, or CFO); and at least one director from a minority ethnic background — with standardized numerical tables for gender and ethnicity across the board and executive management. No LGBTQ+ requirement.
The Parker Review and FTSE Women Leaders Review
Voluntary reviews with teeth: the Parker Review’s ethnic diversity targets are why UK race/ethnicity disclosure is strong (98% of the FTSE 100 now has at least one ethnic-minority director), and the FTSE Women Leaders framework drove women’s board representation past its 40% benchmark.
The Corporate Governance Code
The FRC’s Code says boards should promote "diversity of gender, social and ethnic backgrounds, cognitive and personal strengths," and annual reports must describe D&I policies — but there is no LGBTQ+ reporting obligation. An FRC study found only 2% of FTSE 100 companies mentioned having LGBTQ+ senior role models.
Stronger investor pressure than the US
The transatlantic split runs through stewardship: ISS suspended US diversity voting factors but kept its UK policies, and Glass Lewis’s 2026 UK guidelines vote against nomination-committee chairs at FTSE 350 companies below 40% gender diversity. UK boards now face stronger investor diversity pressure than their US peers.
What changed since our last report
Dated developments from mid-2024 through July 2026, compiled for the OutQUORUM 2026 cycle. Each item links to its source.
- Jul 29, 2024 ENACTED
New UK Listing Rules take effect; board diversity disclosure carried over intact
The FCA’s wholesale rewrite of the listing regime preserved the board diversity targets-disclosure rules as UKLR 6.6.6R(9)–(11), with the standardized data tables in UKLR 6 Annex 1R. The legal basis for FTSE 350 diversity reporting is uncontested and in force.
- Mar 11–12, 2025 WITHDRAWN
FCA and PRA drop their proposed financial-sector D&I framework
Both regulators confirmed they would not proceed with the 2023 consultation requiring regulated firms to set D&I strategies, targets, and data reporting — citing cost and the deregulation agenda. Important nuance: this affects financial firms as employers; the listed-company board diversity rules remain in force.
- Mar 11, 2025 DATA
Parker Review 2025: FTSE 100 at 95% on "one ethnic-minority director"
The FTSE 250 reached 86% among respondents; FTSE 350 companies set their own senior-management ethnic-diversity targets for December 2027.
- Jun 3, 2025 ENACTED
FRC publishes the streamlined UK Stewardship Code 2026
The revised Code reframes stewardship around long-term client value and demotes diversity from the headline definition to supporting guidance — widely read as part of the UK’s ESG-softening trend, though the disclosure architecture is untouched.
- Nov–Dec 2025 POLICY
Glass Lewis 2026 UK policy hard-wires the 40% benchmark
From February 2026, Glass Lewis recommends against the nomination-committee chair at FTSE 350 companies whose boards fall below 40% gender diversity, absent mitigating circumstances — effectively converting the FCA benchmark into voting outcomes.
- Feb 24, 2026 DATA
FTSE Women Leaders Review: women hold 42.7% of FTSE 350 board seats
69% of FTSE 350 companies meet or exceed the 40% benchmark; no all-male FTSE 350 boards since 2020. The unfinished business is the executive pipeline: only 8.2% of CEOs are women.
- Mar 10, 2026 DATA
Parker Review 10-years-on report: record ethnic diversity
98% of the FTSE 100 has at least one ethnic-minority director; 20% of FTSE 100 board seats are held by ethnic-minority directors; 14 FTSE 100 CEOs are from ethnic-minority backgrounds. The report flagged a disappointing decline in Black representation.
- Mar 25, 2026 PROPOSED
Government confirms mandatory ethnicity and disability pay-gap reporting
Draft legislation mirrors the gender pay-gap framework for employers with 250+ staff, with first reports expected from 2027 — making the UK’s direction of travel more demographic disclosure, not less. A supportive backdrop for voluntary LGBTQ+ self-ID data collection.
It’s taken the United States nine years for 100 companies to change. Imagine if the UK could change all FTSE 350 companies by next year.
What the filings show
The FTSE 350 is the strongest non-US market for LGBTQ+-inclusive board policies, on top of near-universal gender and ethnicity disclosure driven by the FCA’s mandatory tables.

LGBTQ+ Board Diversity Guidelines: UK
Published April 2023 · Produced with DLA Piper
The first-ever LGBTQ+-inclusive board diversity guidelines for the UK. The core argument: the FCA already makes companies count gender and ethnicity — extending the same matrix logic to LGBTQ+ costs nothing and closes the one gap the regulator left open.
