Why DeccanBridge ESG assurance

Credibility that stakeholders can rely on.

As the UK transitions towards mandatory sustainability disclosures, boards require confidence in their ESG data. The FRC, investors and regulators expect non-financial information to meet the same standard of rigour as financial reporting.

Our ESG assurance practice delivers independent limited and reasonable assurance engagements over non-financial information, applying ISAE 3000 and ISAE 3410. We help UK entities navigate TCFD mandates, ISSB adoption, UK SDR requirements and the extraterritorial impacts of the EU CSRD.

Common questions

ESG assurance FAQ.

Why does sustainability assurance matter now?
Mandatory assurance is arriving in waves — CSRD in Europe, ISSB-adopting jurisdictions, India's BRSR Core — and investors increasingly discount unassured ESG claims. Data credibility is becoming a market-access issue.
What does ESG assurance readiness involve?
Data lineage and controls for sustainability metrics built to the standard financial data enjoys — measurement methodologies, system trails and evidence an assurance provider can actually test.
Can the same firm advise on ESG strategy and assure it?
No — independence rules apply. We help you sequence providers so the strategy work and the assurance never contaminate each other.

Need assurance your ESG data can withstand scrutiny?
