From Experience: Leading One of the UK's First B Corp Certifications
I led one of the earliest B Corp certifications in the UK. The process was rewarding, but it was also gruelling — months of chasing documents, coordinating across teams, and manually assembling evidence that our business was doing what we said it was.
The hardest part wasn't the assessment itself. It was keeping the momentum afterwards. Once we'd crossed the line, the day-to-day pressures of running a business meant B Corp practices started to drift. When recertification came around three years later, it felt like starting from scratch.
That experience is exactly why we built ESG:ONE. Not as a shortcut to certification, but as the operating layer that makes continuous improvement the default — so B Corp doesn't become a three-year scramble, but something woven into how you run your business every day.
What's Changed in the New B Corp Standards (2026)
In April 2025, B Lab published the most significant overhaul of B Corp standards in its 19-year history. The old points-based system — where you could score 80 on the B Impact Assessment by being strong in some areas and weak in others — is gone.
In its place is a mandatory requirements framework. Every B Corp must now meet specific minimum standards across seven Impact Topics, with escalating expectations at Year 0 (initial certification), Year 3, and Year 5. You can no longer offset weaknesses in one area with strengths in another.
There are also major structural changes: all assessments now go through independent third-party auditors (To-Cert and SCS Global Services), and EU-facing companies must align with the Empowering Consumers for the Green Transition (ECGT) directive by September 2026.
SMEs recertifying in 2026 receive a 12-month extension but must transition to the new standards. Companies certifying for the first time can submit under V2.1 from March 2026. Version 1.6 submissions are now closed.
The Seven Impact Topics Every B Corp Must Address
Under the new standards, Foundation Requirements (eligibility, legal commitment, risk profiling) are the entry point. Once met, companies must demonstrate performance across all seven topics — tailored by size, sector and industry, but non-negotiable in scope.
Purpose & Stakeholder Governance
Public purpose statement, stakeholder governance structures, materiality assessments for larger companies.
Climate Action
Climate transition plans, GHG reporting, science-based targets for larger companies, 1.5°C alignment.
Fair Work
Fair wages, worker feedback mechanisms, dignity and wellbeing, positive workplace culture.
Justice, Equity, Diversity & Inclusion
Diversity data, equitable practices within and beyond the workplace, inclusive recruitment and advancement.
Human Rights
Due diligence across operations and supply chain, proactive identification and mitigation of human rights risks.
Environmental Stewardship & Circularity
Biodiversity, water, waste monitoring. Circular economy principles in product design and operations.
Collective Action
Transparent lobbying, responsible tax, participation in systemic change through mentoring, advocacy and collaboration.
Why B Corp Certification Software Matters Now
The new standards embed continuous improvement as a formal requirement. Certification is phased: you must meet Year 0 requirements to certify, then progressively meet escalating requirements at Year 3 and Year 5. This means B Corp is now an ongoing operational commitment, not a periodic admin exercise.
Meet all Foundation Requirements and baseline sub-requirements across seven Impact Topics. Complete risk profiling. Adopt stakeholder governance legally.
Maintain all Year 0 requirements plus meet additional sub-requirements. Demonstrate measurable progress. Larger companies: validated science-based targets, formal materiality assessments.
Meet the complete set of sub-requirements. Show sustained improvement and systemic impact. Third-party audit verification of all claims.
If certification now requires continuous data collection, progress tracking, and evidence management across seven topics over five years, doing it in spreadsheets isn't viable. You need a system that collects, tracks, and reports automatically — and that's what ESG:ONE does.
How ESG:ONE Maps to Every Impact Topic
ESG:ONE isn't a generic sustainability tool. It's built to address the specific data, documentation, and reporting requirements that the new B Corp standards demand — across all seven Impact Topics.

The platform also generates AI-supported policy documents, tracks progress against Year 0/3/5 milestones, and produces audit-ready reports — so when your third-party verification comes, you're prepared.
What B Corp Certification Looks Like With Software
Imagine you're a 60-person professional services company preparing for first-time B Corp certification under the new standards. Here's how the process works with ESG:ONE versus the typical manual approach.
Without software: You spend weeks creating spreadsheets for each Impact Topic. You email department heads for data, chase them again, manually compile evidence, and hire a consultant to gap-analyse your current position. When recertification comes, you start again because nothing was maintained in between.
With ESG:ONE: You onboard in a day. The platform runs an automated gap analysis against the new standards, identifies which sub-requirements you meet and which you don't, and generates an action plan. Data collection is automated through integrations and built-in surveys. Progress is tracked in real time. When your auditor asks for evidence on any of the seven Impact Topics, you export it directly from the platform — with a full audit trail.
The difference isn't marginal. Our clients typically report that preparation time drops by 60–70%, and — more importantly — they maintain compliance continuously rather than in three-year sprints.
