ESG reporting examples — UK case studies
Real UK examples of ESG reporting across FTSE 100 and FTSE 250 companies. How leading UK preparers handle UK SRS-aligned disclosure, TCFD scenario analysis, Scope 3 measurement, board governance, and the transition from CSR-style reports to investor-focused ESG.
Why look at examples
UK ESG reporting practice has evolved dramatically since SECR began in 2019. Looking at real examples helps preparers understand patterns, avoid pitfalls, and benchmark their own disclosure.
The annual report tells you what management thinks investors need to know. The ESG section reveals how seriously they take that question.
FRC corporate-reporting review commentary
SECR became mandatory in April 2019,1 the SI 2022/31 TCFD-aligned climate disclosure requirement applied from accounting periods beginning on or after 6 April 2022,2 and UK SRS S1 and S2 were published by DBT on 25 February 2026.3 These three waves of regulation explain why UK ESG reporting has evolved so rapidly since 2019.
Five patterns in UK ESG reporting practice
From FRC thematic reviews of TCFD reporting and investor commentary, five patterns characterise current UK practice across FTSE 350.
- 1. The dedicated TCFD sectionPattern
- Most FTSE 100 annual reports now have a dedicated 8-20 page TCFD section within the strategic report, structured by the four pillars (Governance, Strategy, Risk Management, Metrics & Targets).4 The best examples include physical and transition risk tables, quantitative scenario analysis with financial impact, and Scope 1/2/3 emissions tables. The FRC publishes annual thematic reviews assessing quality of TCFD disclosure.5
- 2. The NFSIS umbrellaPattern
- Companies in scope of SI 2022/312 wrap their TCFD section within a wider Non-Financial and Sustainability Information Statement covering social topics (workforce, modern slavery), governance (anti-bribery, ethics) and environmental matters beyond climate (water, biodiversity).
- 3. The materiality matrixPattern
- Standard component of most UK SRS-aligned reports. Plot of ESG topics on two axes (financial materiality vs stakeholder importance). Most FTSE 100 reports show 10-20 plotted topics with movement vs prior year. Quality varies — best examples show the methodology and stakeholder engagement underlying the matrix.
- 4. The integrated KPI dashboardPattern
- A single dashboard at the front of the strategic report combining financial KPIs (revenue growth, ROIC, EPS) with ESG KPIs (Scope 1+2 emissions, gender pay gap, lost-time injury rate). Increasingly common; UK SRS connectivity requirements will accelerate this.
- 5. The standalone sustainability reportPattern
- Most FTSE 100 groups publish a 50-150 page sustainability report alongside the annual report, often GRI-aligned. Covers impact materiality and stakeholder narratives that don't fit the investor-focused annual report. Will likely shrink as UK SRS S1 takes effect from 2029.
Before vs after UK SRS
What changes in a typical FTSE 250 ESG report when UK SRS S2 becomes mandatory from 2027. Four substantive shifts in content and structure.
- Scenario analysis: narrative → quantitativeSubstantive shift
- Pre-2027: scenario analysis often qualitative — ‘the company has considered a 2°C scenario and identified key risks’. Post-UK SRS S2: quantitative financial impact required.3 Typical practice will show NGFS scenarios with sector-specific revenue, cost and impairment impacts modelled across 2030, 2040 and 2050.
- Scope 3: where appropriate → mandatorySubstantive shift
- Pre-2027: Scope 3 disclosed where ‘material’ (TCFD wording) or ‘appropriate’ — many companies disclose just Categories 1, 6, 7 and 11. Post-UK SRS S2: all material Scope 3 categories mandatory with comply-or-explain relief year one.3 Audit-readiness raises the bar on data quality.6
- Connectivity to financials: encouraged → mandatorySubstantive shift
- Pre-2027: many companies publish ESG data in standalone reports loosely linked to the annual report. Post-UK SRS S2: explicit cross-referencing between ESG disclosures, climate-related impairments, contingent liabilities and going-concern statements; same-time-same-period reporting.4
- Industry-specific metrics: optional → expectedSubstantive shift
- Pre-2027: SASB industry metrics referenced by some companies as good practice. Post-UK SRS S2: industry-specific metrics expected (SASB referenced but optional under the UK amendment). Energy companies report flaring intensity; healthcare reports medicine access; financials report financed emissions.
Quantification, Scope 3, connectivity, industry specificity
UK SRS S2 builds directly on TCFD architecture but tightens each pillar.
Listed companies preparing FY 2026 TCFD reports should use them as a foundation for FY 2027 UK SRS S2 reports — same governance, same strategy framework, same risk management process — but with materially more depth on quantification, Scope 3 measurement, integration with financial statements, and industry-specific metrics.
FCA CP26/5, published in January 2026, proposed that mandatory UK SRS S2 reporting for ~515 listed companies begins for accounting periods starting on or after 1 January 2027.4 The FRC’s thematic reviews of TCFD reporting provide the clearest publicly available assessment of current UK practice against the standard.5
Primary sources of UK ESG reporting examples
Five sources UK preparers should benchmark against. From FTSE 100 annual reports to FRC thematic reviews to peer-group sustainability reports.
- FTSE 100 annual reportsPrimary source
- The gold standard. Most include dedicated TCFD sections, materiality matrices, scenario analysis, Scope 1/2/3 emissions, governance tables. Useful for size-appropriate benchmarking — pick three peers in your industry as reference.
- FRC thematic reviewsRegulatory source
- The FRC publishes periodic thematic reviews of TCFD reporting, climate-related financial disclosures, and viability statements.5 Show what regulators consider good vs poor practice with anonymised examples.
- FTSE 250 mid-cap reportsComparable source
- More directly comparable for many UK preparers. Look for mid-cap peers in your industry who have been through TCFD reporting twice or three times — the second-year reports tend to be much improved on the first.
- Investor coalition resourcesInvestor view
- Climate Action 100+, Institutional Investors Group on Climate Change (IIGCC) and Investment Association publish benchmark assessments of large company reporting against investor expectations.
- International examplesReference source
- Australian ASRS-aligned reports (early adopters of IFRS S1/S2); Japanese SSB-aligned reports; EU ESRS-compliant reports from large multinationals (BP, Shell, Unilever for combined ESRS + UK SRS reporting).
ESG reporting examples — frequently asked
Where to find good examples, which UK companies lead, small-company requirements, and typical report length.
Where can I find good ESG report examples?
FTSE 100 annual reports are the best primary source for UK ESG reporting examples — they generally exceed the regulatory minimum and include TCFD-aligned climate sections, NFSIS disclosure under SI 2022/31, and increasingly UK SRS-style early-adopter language.
The FRC publishes thematic reviews of TCFD reporting with examples of good and poor practice.
Which UK companies have the best ESG reports?
Common reference points cited in FRC thematic reviews and investor commentary include: Unilever (integrated reporting pioneer), Diageo (climate and Scope 3), Shell (transition planning), AstraZeneca (climate scenarios), HSBC (financed emissions).
The 'best' depends on the angle — investor utility, regulatory completeness, or quality of narrative.
Do small UK companies need ESG reports?
Not yet directly under UK regulation — SI 2022/31 catches companies with 500+ employees; SECR has thresholds around 250 employees or £36m turnover.
But small companies increasingly face indirect ESG reporting pressure through supply-chain requests from large customers, lending criteria from banks, and customer/investor expectations.
The Government is consulting on extending mandatory reporting to large private companies through Modernising Corporate Reporting.
How long are typical UK ESG reports?
Currently 30-80 pages of dedicated ESG / sustainability content within FTSE 350 annual reports, plus a separate sustainability report of 50-150 pages from many large groups.
Under UK SRS, the trend will be toward more integrated reporting within the annual report itself — the FCA's CP26/5 emphasises connectivity between sustainability disclosures and the financial statements.
