Fox Williams LLP recently participated in a UKFT webinar, From Application to Accreditation: The B Corp Path. Following on from the webinar, Fox William’s Anjali Aravindhan, a corporate associate, and Paul Taylor, a corporate partner, share key legal insights for businesses considering the journey to B Corp certification.

 

Understanding B Corp Certification

A B Corp, or Benefit Corporation, is a company that meets the highest standards of verified social and environmental performance, public transparency and legal accountability. B Corps are for-profit businesses that aim to balance profit with purpose. The B Corp certification is granted by B Lab, which is a non-profit organisation that certifies companies based on their overall social and environmental performance.

B Corp certification has been gaining momentum globally and in the UK. Companies are increasingly embracing this framework to demonstrate to customers, employees and the wider public, their commitment to social and environmental responsibility.

Why pursue certification?

The rationale for pursuing B Corp status is multifaceted:

• Corporate leadership and responsibility: Certification signals a genuine and legally embedded commitment to environmental and social impact, moving beyond traditional corporate social responsibility statements.
• Talent attraction and retention: Employees increasingly favour organisations that demonstrate alignment with personal values and responsible business practices.
• Reputation and market positioning: Certification enhances consumer trust, bolsters brand value, and can create opportunities for partnerships, collaborations, and investment within a global network of certified companies.

These benefits were echoed by panellists during the recent UKFT webinar, who highlighted the reputational value of certification. Several speakers noted that B Corp status has not only attracted employees who are passionate about sustainability but also opened up new conversations with investors who view certification as evidence of long-term resilience and governance maturity.

Legal requirements for UK businesses

Historically, companies have tended to operate under a doctrine known as shareholder primacy, which enables companies to prioritise profits even when those profits are derived from behaviours that create inequality, environmental damage and social fragmentation.

Increasingly, however, business leaders have called for a shift away from the shareholder primacy doctrine in favour of a model known as stakeholder governance. This corporate governance practice prioritises all stakeholders – customers, workers, suppliers, communities, investors and the environment – in decision-making. Stakeholder governance ensures that businesses are accountable to people and planet, and this accountability is a key requirement for B Corp companies.

Amendments to articles of association

The primary legal step for UK companies is to amend their articles of association. In practice, this usually involves adopting B Lab’s model wording, which codifies stakeholder governance obligations.

This amendment must be passed by special resolution, requiring the support of at least 75% of shareholders. Once approved, the revised articles of association must be filed at Companies House and so become a matter of public record. For companies with multiple shareholders or external investors, early engagement is essential to ensure alignment with the business’s long-term strategy and to secure the necessary level of approval. While this step is fairly straightforward on paper, it’s a crucial moment to align your internal stakeholders and set the tone for your B Corp journey.

Shareholder and investment agreements

Before amendments can be made, it is critical to review existing shareholder agreements or investment agreements. Many of these documents include provisions requiring investor majority consent – or the consent of specific investors – for constitutional changes. Failure to obtain such consent may prevent amendments from being lawfully adopted, making it critical to involve investors at the outset.

A number of panellists underlined this point, with several highlighting that early engagement with investors smoothed the certification process. By framing B Corp as a mechanism for safeguarding long-term brand value and enhancing governance, companies were able to secure the necessary approvals without significant resistance.

Ongoing compliance

Following certification, companies must continue to ensure their articles of association remain compliant with UK law and that directors’ duties under the Companies Act 2006 are properly discharged. The introduction of stakeholder governance increases the complexity of board decision-making and places greater emphasis on documenting how stakeholder interests are considered in practice.

The certification process

Once governance and shareholder approvals are in place, companies progress to the B Impact Assessment (BIA). This is a comprehensive evaluation of the business’s social and environmental performance across five areas: governance, workers, community, environment and customers.

Key elements include:

• Completion of the BIA: This online assessment evaluates a company’s policies and practices across a range of areas, including governance structures, employee benefits, supply chain transparency, charitable initiatives and environmental management.
• Achievement of the scoring threshold: To qualify for certification, an applicant must obtain a verified score of at least 80 points out of a possible 200.
• Verification by B Lab: Supporting documentation must be provided to substantiate responses within the BIA. B Lab may also conduct follow-up enquiries or site visits, particularly in the case of larger or more complex organisations.
• Ongoing recertification: Certification is not a one-off exercise. Companies are required to undergo recertification every three years, demonstrating that they have maintained or improved their performance across the assessed areas.

From a practical perspective, panellists emphasised that the BIA can be as valuable as certification itself.

Several businesses reported that the assessment uncovered blind spots in areas such as supply chain transparency or employee wellbeing, prompting improvements even before the application was submitted. Others noted that the exercise created new internal momentum, bringing different departments together to deliver on shared sustainability goals.

The BIA should therefore not be regarded as a compliance exercise alone. For many businesses, it functions as a strategic diagnostic, highlighting areas of strength and exposing opportunities for improvement. Even prior to certification, companies often derive measurable benefits from the process of self-assessment.

Looking ahead

With updated B Corp standards due to be implemented, companies can expect more prescriptive requirements in core areas such as climate action, worker wellbeing and risk management. Early engagement with the BIA positions businesses to adapt to these changes and strengthen their governance structures accordingly.
