B Corp certification has become one of the more recognised symbols of business sustainability in the UK. The B Corp logo appears on bottled water, banking apps, fashion labels, restaurants and consumer products. The credibility of the certification matters because most other sustainability claims aren't independently verified.

This is what B Corp certification actually is, what it requires, and why KeepCup invests in maintaining it.

What B Corp Is

B Corporation is a third-party certification administered by B Lab, a non-profit organisation that operates the standard globally. To be certified, a company must:

  1. Complete the B Impact Assessment, a detailed questionnaire covering five impact areas: Governance, Workers, Community, Environment and Customers.
  2. Score above the threshold across the combined impact areas.
  3. Meet a set of foundation requirements (purpose and stakeholder governance, climate action, human rights, fair work, environmental stewardship, circular economy and just transition).
  4. Make a legal commitment to consider all stakeholders, not just shareholders, in business decisions.
  5. Submit to verification of evidence supporting their answers.
  6. Recertify every three years against the current standard.

The standard has tightened over time. The most recent major update (2023) introduced the foundation requirements as pass-or-fail criteria, meaning a company can have a strong overall score but still fail certification if it doesn't meet the foundation requirements.

What B Corp Isn't

Worth being clear about what the certification doesn't claim:

  • It's not a product standard. B Corp certifies businesses, not products. A specific product from a B Corp brand may or may not be the most sustainable option in its category.
  • It's not a regulatory framework. B Corp is voluntary. Regulatory compliance is separate.
  • It's not permanent. Certification is granted for three years and requires recertification against the then-current standard. Companies that fall behind lose certification.
  • It's not a pass on every dimension. A B Corp can score high overall while having weaknesses in specific areas. The certification is a holistic standard, not category-specific perfection.

Why It Still Matters

Despite the limitations, B Corp is the strongest available standard for verifying business sustainability claims for three structural reasons:

1. It's Independently Verified

B Lab is not the business being certified. Evidence is reviewed, sampled and verified. Companies can't self-certify.

2. The Standard Tightens

Each recertification cycle uses an updated standard reflecting evolving expectations. The 2023 update raised the bar significantly. Companies that don't keep improving lose certification.

3. It Covers the Full Business

Unlike product-specific certifications, B Corp evaluates the entire business, governance, workforce, supply chain, environmental practice, customer relationships. It's harder to game because the surface area is large.

KeepCup as a B Corp

KeepCup has been a Certified B Corporation since 2017. We've completed multiple recertification cycles, including the most recent under the 2023 standard. The certification has driven measurable operational changes:

  • Stakeholder governance documented in company constitution.
  • Climate commitments aligned with international scientific consensus.
  • Supplier code of conduct strengthened with documented due diligence.
  • Circular economy practice formalised through modular replacement parts.
  • Workforce policies aligned with living wage and equitable practice principles.

The recertification cycles have repeatedly identified gaps and required improvement. The certification isn't a sticker we earned once, it's an ongoing discipline.

How to Use B Corp as a Customer

For a UK customer evaluating sustainability claims, B Corp certification is one of the strongest filters available. Practical use:

  • If a brand claims sustainability without B Corp certification, the foundation isn't independently verified.
  • If a brand is B Corp certified, the foundation is verified. Look at specific product attributes for category-specific evaluation.
  • If a brand is a Best for the World honouree, verified top-tier performance in at least one impact area.
  • If a brand lost B Corp certification, understand why before drawing conclusions.

The Bigger Frame

B Corp is not perfect. It's a third-party voluntary standard with limitations, critics and continuing evolution. It is also, in the current UK and global landscape, the strongest available verified standard for business sustainability practice.

Used honestly, the certification helps customers identify businesses that are actually doing the work behind the marketing. KeepCup's certification represents that work for our business. The work continues regardless of any individual recertification outcome.
