Better Health for All

No evidence was found in the provided articles that directly pertains to the ethical value of 'Better Health for All' as defined. The article discusses internal health and safety performance (Accident Frequency Rate of 0.1

, Total Recordable Incident Rate of 0.6 in 2023 ) and a global wellbeing framework for employees, which are explicitly excluded from this value category as they fall under 'Fair Pay & Worker Respect'.

Fair Pay & Worker Respect

In 2023, Keller Group reported a Total Recordable Incident Rate (TRIR) of 0.6

and an Accident Frequency Rate (AFR) of 0.1 .

The company states a commitment to ethical employment practices, including policies against modern slavery and human trafficking , and promotes diversity and equal opportunities, as evidenced by its Investors in Diversity status for Keller UK and the launch of an Inclusive Site Culture standard in 2023 .

Fair Trade & Ethical Sourcing

The company demands adherence to international human rights standards, including those covering child and forced labor, and has enhanced supplier due diligence with updated contractual clauses reflecting ethical commitments. An internal working group assesses labor standards. However, the provided articles do not contain specific quantitative data points such as the percentage of fair-trade certified spend, supplier audit frequency, number of substantiated forced or child labor incidents, supply chain traceability coverage, median days to close corrective action plans, percentage of contracts with enforceable ethical clauses, share of spend on high-risk materials, or the percentage of procurement budget directed to diverse suppliers. Therefore, no KPIs can be scored against the rubric's quantitative thresholds.

Honest & Fair Business

Keller identified a deliberate financial reporting fraud in its Austral business unit in January 2023

, which resulted in an overstatement of operating profits by approximately £6 million in the first half of 2022 and an additional £8 to £10 million in prior years . This indicates at least two periods were affected, averaging 0.4 restatements per year over the past five years. The company has a Whistleblowing Policy and a third-party whistleblowing helpline . Additionally, Keller has established a Code of Business Conduct, including an Anti-Bribery and Anti-Fraud Policy , and appoints Ethics and Compliance Officers in every business unit, conducting compliance workshops .

Kind to Animals

Keller Group PLC is a geotechnical specialist contractor, and its core business operations do not involve animal testing, animal-derived products, animal agriculture, or direct animal-related services. Therefore, most KPIs related to cruelty-free certification, animal testing, humane operations, ethical sourcing, and animal agriculture are not applicable to the company's business model. While the company focuses on environmentally conscious construction practices, including enhancing equipment inspections to minimize ecological impact

and completing Environmental Impact Assessments for 95% of projects to identify impacts on ecosystems , the provided articles do not offer specific, measurable data on biodiversity impact, species recovery, habitat restoration metrics, or the percentage of revenue dedicated to conservation initiatives, which are required to score the 'wildlife_conservation_impact' KPI.

No War, No Weapons

Keller Group PLC reported zero recorded incidents of modern slavery or human trafficking in 2024, supported by enhanced due diligence processes embedded into procurement systems in 2024

and mandatory ethics and compliance training for employees . The company explicitly states its commitment to and abides by the UN Guiding Principles on Business and Human Rights , is a member of the UN Global Compact , and issues an annual Modern Slavery and Human Trafficking statement . In 2024, Keller contributed £250,000 to UNICEF’s Core Resources for Results , representing approximately 0.0083% of its £3.0 billion annual group revenue .

Planet-Friendly Business

No specific, company-wide, and quantitative data was found in the provided articles to assess Keller Group PLC against the defined KPIs for Planet-Friendly Business. Information regarding total carbon emissions, renewable energy use across all operations, water consumption per revenue, waste diversion rates, or specific environmental certifications was either not provided, pertained to future initiatives, was limited to single projects or facilities, or was a reduction percentage without the absolute baseline, thus not meeting the criteria for company-wide assessment against the rubric's thresholds. While net-zero targets for 2050 with interim milestones were mentioned

, the rubric does not provide a specific tier for a 2050 target with interim milestones, leading to its omission.

Respect for Cultures & Communities

In 2018, Keller successfully completed a project involving the preservation of a heritage-listed building dating back to the mid-1800s.

This project utilized extensive engineering solutions, including over a hundred jet grout underpinning columns, 60 vertical and inclined retaining micropiles, 51 foundation micropiles, and several multi-strand soil anchors , demonstrating a commitment to cultural heritage protection.
