Materiality Assessment for Food & Drink Suppliers

Supplying UK supermarkets means meeting sustainability expectations. 

What Is a Materiality Assessment?

A materiality assessment is a structured process that identifies which environmental, social and governance (ESG) issues are most important to your business and your stakeholders.

It helps you understand:

• Where your biggest sustainability impacts occur
• What issues present the greatest risk or opportunity
• Which issues matter most to customers, retailers, employees and regulators
• Where to focus limited time and resources for maximum effect
• How to build a credible foundation for future reporting and action

Materiality is widely used in sustainability reporting frameworks such as the GRI Standards and is increasingly referenced in UK and international sustainability regulations including The UK Sustainability Reporting Standards (SRS) and The Corporate Sustainability Reporting Directive (CSRD)

Why Materiality Matters for Suppliers

Sustainability expectations are accelerating across the UK. Supermarkets are tightening their requirements, and national legislation is moving toward more consistent, transparent sustainability reporting. For food and drink suppliers, this means one thing: understanding your material issues is no longer optional.

A Clear Response to Growing Legislation

The UK is preparing to introduce UK Sustainability Reporting Standards (SRS), which will be based on the International Sustainability Standards Board (ISSB) framework. These standards will require organisations to:

• Identify their material sustainability issues
• Demonstrate how those issues were assessed
• Report on impacts, risks and opportunities in a structured, decision‑useful way

This shift mirrors global moves such as the EU’s CSRD and the ISSB’s IFRS S1 and S2 standards, all of which place materiality at the centre of credible sustainability reporting.

For suppliers, this matters because supermarkets are aligning their own reporting with these standards and passing expectations up the supply chain.

Get Ahead of the Curve

Completing a materiality assessment now gives your business a strategic advantage:

Prioritising action to respond to your biggest impacts, risks and opportunities.

A Business Advantage Not Just a Compliance Exercise

Materiality isn’t just about meeting expectations. It helps you:

• Focus limited resources on the issues that genuinely matter
• Strengthen internal decision‑making
• Identify risks early and build resilience
• Prioritise actions that support long‑term commercial success
• Communicate clearly and confidently with supermarkets, investors and employees

Advantages of Conducting a Materiality Assessment

Materiality insights guide investment, resource allocation and long‑term planning.

A clear materiality process strengthens your sustainability reporting and aligns them with recognised frameworks.

5. Reduce Risk and Increase Resilience

Identifying emerging ESG risks early helps you stay ahead of regulatory and retailer expectations.

Considerations When Conducting a Materiality Assessment

When  businesses complete a materiality assessment, the most important considerations include:

• Stakeholder engagement: Who needs to be consulted internally and externally?
• Scope: Which environmental, social and governance topics are relevant to your operations and supply chain?
• Data availability: What information do you already have, and where are the gaps?
• Retailer expectations: Which issues are supermarkets most likely to scrutinise?
• Business strategy: How do sustainability priorities align with commercial goals?
• Practicality: What can be achieved with your current resources and capacity?
