What B Corp certification actually involves

B Corp certification is awarded by B Lab to companies that demonstrate they meet a structured set of mandatory performance requirements across governance, workers, community, environment and customers. The old system required companies to score 80 points on the B Impact Assessment. That model has now been replaced — there are no longer points. Instead, companies must meet a set of "Year 0" sub-requirements to achieve certification, then progress to additional requirements at Year 3 and Year 5. For most mid-market businesses, reaching that threshold still requires a genuine internal audit, legal documentation changes, and a verification process that typically takes six to twelve months or more.

The new standards: what changed in 2025–2026

On 8 April 2025, B Lab launched the most significant overhaul of the B Corp standards to date, responding to growing regulatory demands — especially the EU's Empowering Consumers for the Green Transition (ECGT) directive — and to criticism that the previous self-assessment and points-based model was too flexible.

The new standards have a two-part structure. Foundation Requirements are universal prerequisites every company must meet regardless of size or industry. On top of that, certification now requires meeting tailored requirements across seven Impact Topics, with specific requirements scaled based on a company's size, sector, and industry.

The seven core Impact Topics include Climate Action, Fair Work, and Human Rights. Every certified company must now meet baselines across all of these rather than offsetting weaknesses in one area with strengths in another.

The certification cycle has also extended from three years to five years, with companies expected to advance their actions over that period — initially meeting the Year 0 requirements, then gradually complying with Year 3 and Year 5 requirements. More regular surveillance audits will monitor compliance during those five years.

Third-party auditing by independent external auditors has also been introduced, replacing much of the previous self-assessment model. To-Cert and SCS Global Services are the audit partners.

Why it's harder in practice than it looks

The scoring system no longer allows offsettingPreviously, a company could score poorly on environment but compensate with strong worker or governance scores. That loophole is now closed. Companies must demonstrate balanced performance across all Impact Topics, which better reflects authentic impact but makes preparation more demanding.

Legal structure changes remain non-negotiable and often slowUK businesses must still amend their articles of association to embed stakeholder governance before B Lab will certify them. For companies with institutional shareholders, complex holding structures, or debt covenants, that change requires legal counsel and board approval and can take several months.

The supply chain sections expose data gapsCommunity and environment questions ask about supplier practices, local procurement percentages, and charitable giving as a share of revenue. Companies that have never formally tracked these figures have to reconstruct historical data before they can answer accurately.

Verification is now conducted by independent third partiesThe updated standards require third-party audits by accredited bodies, making sustainability claims far more defensible — but also raising the bar for the quality of evidence required.

The five-year cycle embeds continuous improvementCompanies must now demonstrate measurable progress to be recertified and show plans for improvement, making the certification less of a box-ticking exercise and more about advancement over time.

Timing and transition: what applies now

From March 2026, new companies certifying for the first time must submit under the new V2.1 standards. Submissions on the old V1.6 are now closed. B Corps with recertification dates in 2026 have received a 12-month extension but must transition to the new standards.

For companies operating in the EU and engaging in B2C communications, B Lab strongly recommends beginning self-assessment against the new standards now to ensure readiness, with the ECGT compliance deadline of September 27, 2026 acting as a hard deadline for affected companies.

What good looks like

A well-prepared submission under the new standards includes: a fully completed self-assessment against the V2.1 Foundation Requirements and all relevant Impact Topics with supporting documentation; board-approved articles of association reflecting stakeholder consideration; a baseline emissions figure for Scope 1 and 2; a written environmental policy with measurable targets; and a worker survey with a response rate above 80 percent. The strongest submissions are built by companies that ran an honest gap analysis first, prioritised improvements in areas where evidence was missing, and assigned a single internal owner to coordinate across HR, legal, finance and operations.

When to bring in external support

Most sustainability teams do not have the bandwidth to run a B Corp project alongside existing reporting obligations. The new standards span HR, supply chain traceability, governance, environmental management, and EU regulatory compliance — areas that rarely sit within a single team's expertise. A specialist who has guided multiple companies through certification under the new framework can provide an honest gap assessment before submission, saving significant time and back-and-forth.

Leafr's network includes B Corp specialists who have supported certification projects for consumer brands, professional services firms and manufacturers across Europe, typically helping companies achieve their target significantly faster than those working without focused external support. Projects start within 48 hours of engagement.

Frequently asked questions

What is B Corp certification and how is it different from a sustainability report?

‍B Corp certification is a third-party verified status awarded by B Lab to companies that meet defined standards of social and environmental performance. Unlike a sustainability report, which is self-disclosed, B Corp status requires independent verification and legal changes to a company's governing documents. It signals accountability, not just disclosure.

How long does B Corp certification take?

‍For most mid-market companies, the process takes 12 to 18 months from starting the self-assessment to receiving certification. Under the new standards, the largest time costs are closing gaps identified during self-assessment, preparing supporting documentation, and completing third-party verification.

How much does B Corp certification cost?

‍B Lab's certification fees are tiered by revenue. These fees do not include legal costs for articles of association changes, staff time, or external consultancy. The updated pricing structure reflects the costs of the new third-party assurance process. Total project costs for a mid-market business often still fall between £30,000 and £100,000 when all factors are included.

What replaced the 80-point B Impact Assessment score?

‍The new B Corp standards replace the flexible 80-point score with a set of specific, mandatory requirements all B Corps must meet. A company must now meet a baseline in every critical area rather than compensating for weaknesses elsewhere. The minimum passing score threshold no longer applies.

Is B Corp the same as being a benefit corporation?

‍No. B Corp certification is a third-party accreditation awarded by B Lab. A benefit corporation is a legal business entity structure available in certain US states. In the UK, companies certify as B Corps by amending their articles of association rather than changing their legal structure.

What are the most commonly challenging areas under the new standards?

‍The seven mandatory Impact Topics mean no area can be neglected. Climate Action (quantified emissions and reduction targets), Fair Work (living wage policies, worker equity), and Human Rights tend to require the most preparation. Companies with long or complex supply chains also face significant additional requirements.

Can B Corp certification be revoked?

‍Yes. More regular surveillance audits during the five-year cycle mean ongoing compliance monitoring, and B Lab can revoke certification if a significant governance, ethical, or legal issue comes to light. Companies should treat B Corp not as a badge earned once but as an ongoing performance commitment.
