The VSME Standard Explained: What UK SMEs Need to Know in 2026

Your customer just asked you to complete a "VSME-aligned" questionnaire. Now what?

VSME stands for Voluntary Sustainability Reporting Standard for non-listed Small- and Medium-Sized Enterprises. It was published by EFRAG -- the European Financial Reporting Advisory Group -- the same body behind the full European Sustainability Reporting Standards (ESRS) that large listed companies must follow under the Corporate Sustainability Reporting Directive (CSRD). For a detailed look at the template itself, see the EFRAG VSME template guide.

The name matters less than the purpose. VSME exists because of a specific problem: large companies subject to CSRD need sustainability data from their supply chains. Without a standard, every company invents its own questionnaire. SME suppliers end up answering dozens of overlapping but slightly different requests.

VSME sets a ceiling. It defines the maximum amount of sustainability data a large company should reasonably demand from an SME supplier.

Why this affects UK businesses

CSRD is an EU regulation, but it does not stop at EU borders. Any UK SME supplying goods or services to a company reporting under CSRD can expect to receive VSME-aligned data requests. The regulation applies to your customer. The questionnaire lands on your desk.

UK-based SMEs are not legally required to use VSME. There is no UK law mandating it. But if your customer base includes EU-headquartered companies -- or UK subsidiaries of EU groups -- you will likely encounter it. Treating VSME as a practical framework rather than a legal obligation is the right mindset.

The two modules

The final VSME standard, published by EFRAG on 17 December 2024, is structured as two modules. (Earlier drafts — including the November 2023 Exposure Draft — proposed a three-module structure; the final standard consolidated this into two.) Reporting against the Basic Module is a prerequisite for reporting against the Comprehensive Module.

Basic Module

This is the minimum and the entry point for all SMEs. It contains 11 disclosures (B1–B11) covering the core sustainability data most often requested by value chain partners:

• Energy consumption (total kWh, split by source if possible)
• Greenhouse gas emissions (Scope 1 and Scope 2, estimated if necessary)
• Pollution, water, biodiversity and resource use / circular economy basics
• Total workforce headcount and basic characteristics (gender split, contract types)
• Workplace health and safety incidents and remuneration basics
• Whether you have key policies in place (environmental, health and safety, anti-corruption)
• Convictions and fines for corruption and bribery

Most UK SMEs already track this data somewhere -- energy bills, HR records, policy documents. The Basic Module is about pulling it into one place, not generating new data from scratch.

Comprehensive Module

This builds on the Basic Module and adds 9 further disclosures (C1–C9) that banks, investors, and value chain partners more often need:

• A description of your business model, strategy, and sustainability practices or future initiatives
• GHG reduction targets and any climate transition plan
• Climate risks, and how you manage them
• Additional workforce metrics (such as gender pay gap and human rights matters)
• Confirmed value chain incidents relating to human rights
• Whether you are excluded from EU reference benchmarks
• Revenue from certain sectors and exposure data a customer may need for their own reporting

The Comprehensive Module is where you explain the "why" and the "what next" behind your numbers, alongside the additional quantitative detail. Not every customer will ask for the full Comprehensive Module — many will cherry-pick specific disclosures relevant to their industry and reporting obligations.

What data points does VSME actually ask for?

Across the two modules, VSME defines 20 disclosures (11 Basic + 9 Comprehensive) covering a manageable set of individual data points. The most commonly requested ones for UK SMEs tend to cluster around:

• Energy and emissions: annual energy use in kWh, Scope 1 and 2 GHG emissions in tonnes CO2e
• Workforce: headcount, gender diversity percentages, health and safety incident rates
• Governance: whether specific policies exist (environment, anti-bribery, data protection, modern slavery)
• Environmental management: waste generated, recycling rates, water usage
• Supply chain: whether you have a supplier code of conduct, how you assess supplier ESG performance

If you have already responded to supplier ESG questionnaires, most of these will look familiar. VSME did not invent new topics. It standardised existing ones.

How VSME connects to supplier questionnaires

This is the practical payoff. Before VSME, every corporate customer designed their own ESG questionnaire. You might answer 15 questionnaires a year, each asking the same things in slightly different ways.

VSME gives everyone a common reference point. As more large companies adopt VSME-aligned questionnaires, your answers become more reusable. The data points are defined consistently. The categories match up. An answer you prepared for one customer's VSME-aligned questionnaire transfers directly to the next.

This is why building a reusable fact library matters. When the underlying standard is consistent, your stored answers have a longer shelf life.

Practical next steps for UK SMEs

You do not need to implement both modules overnight. A sensible approach:

1. Start with the Basic Module. Use the VSME data checklist to track the Basic Module's 11 disclosures and see which ones you can already fill. Gather your energy bills, HR headcount data, and confirm which policies you have in place. This covers the data points most customers will ask for first.

2. Audit your existing policies. Do you have a written environmental policy? Anti-bribery policy? Health and safety policy? If they exist but are outdated, update them. If they do not exist, draft them. These are binary data points -- you either have the document or you do not.

3. Build your fact library. Record each data point as a standalone, reusable fact. Our free ESG response template generator produces a structured starter document you can populate. When the next questionnaire arrives, you match questions to existing facts rather than starting from scratch.

4. Track your evidence. Every data point should link to a supporting document: the energy bill, the ISO certificate, the board minutes. Customers increasingly ask for evidence, not just answers.

5. Watch for updates. EFRAG continues to refine VSME guidance. The standard may evolve as CSRD implementation matures across Europe. Check EFRAG's published materials annually.

Where AnswerVault fits

AnswerVault's questionnaire templates include VSME-aligned questions mapped to the Basic and Comprehensive modules. You can populate your fact vault against the VSME framework, then reuse those facts whenever a customer sends a questionnaire -- whether it is explicitly VSME-aligned or not.

The keyword matching engine recognises ESG terminology across 65 synonym groups, so even when questionnaires phrase things differently, your stored facts surface as suggestions.
