In short: Environmental topics get most attention, but the social and governance parts of ESG carry their own legal duties and risks. UK employers with 250 or more employees must publish gender pay gap figures every year; organisations with turnover of £36 million or more that supply goods or services in the UK must publish a modern slavery statement; and the EU CSDDD now applies only to the largest groups, from 2029. Investors also look closely at board composition, executive pay linked to ESG targets and anti-corruption controls. TaxDigit's sustainability and payroll specialists calculate, review and draft these disclosures.
The social and governance disclosures that matter most
Social metrics cover how a business treats its workforce, the people in its supply chain, its customers and the communities around it: diversity and inclusion, pay equity, training, health and safety, and human rights. Human rights in the supply chain are usually the hardest to control, so effort should go first to the highest-risk countries, sectors and suppliers.
Governance metrics show how the business is run: board skills, independence and diversity, committee roles, executive remuneration and the share of incentives tied to ESG targets, the CEO pay ratio, anti-corruption policies and training, and tax transparency. These are among the first things investors and rating agencies check.

Frequently asked questions
Who must report their gender pay gap?
Employers in Great Britain with 250 or more employees on the snapshot date. Private and voluntary sector employers use a 5 April snapshot date.
What is the difference between the gender pay gap and equal pay?
The pay gap compares average earnings of men and women across the organisation regardless of role. Equal pay is the legal right to equal pay for equal work.
Who must publish a modern slavery statement?
Commercial organisations carrying on business in the UK that supply goods or services and have a total turnover of £36 million or more.
Why is supply chain human rights so hard to manage?
Because it depends on suppliers you do not control, often in several tiers and countries. Focus on the highest-risk areas first and build collaboration with key suppliers.
Does the CSDDD apply to UK companies?
Only to non-EU companies with more than €1.5bn of EU turnover after the Omnibus changes, from 2029. Most UK groups are outside it, but their EU customers may still ask for due diligence information.
Is executive pay a social or governance metric?
Governance. Board composition, executive remuneration and anti-corruption are governance topics.
Can you calculate our gender pay gap from our payroll?
Yes. Our payroll team works with your data on the snapshot date and we prepare the figures and narrative for publication.
Should ESG targets be part of bonuses?
Many listed companies now include ESG measures in incentives. They work best when they are material, measurable and verified.
