B Corp Certification Pricing

From January 2027, companies looking to certify or recertify as a B Corp will pay an Application & Scoping Fee (where applicable), Annual IP License & Community Fee and an Independent Audit Fee. Discover the certification fees below and explore the support available for entrepreneurs facing systemic barriers to business ownership.

Demonstrate your impact and build trust

Expectations of business are changing. Customers, investors, employees and stakeholders want to understand how a business benefits people and the planet, and to see proof.

B Corp Certification is a rigorous way to assess, improve and independently validate your social and environmental performance.

Under the new B Lab Standards, B Corps meet minimum requirements across seven key areas of impact, from climate action to human rights. Performance against these areas is audited by an independent, third-party assurance provider.

This new model reflects international best practice through ISEAL, strengthening the rigour and market credibility of B Corp Certification while delivering regulatory alignment with anti-greenwashing rules, including the UK’s Advertising Standards Authority and the EU's Empowering Consumers for the Green Transition (ECGT) Directive.

What do people think about B Corps?

Awareness of B Corp in the UK grew from 34% in 2022 to 51% in 2024, reflecting its increasing recognition as a marker of a business’s positive impact among consumers. The Financial Conduct Authority also references the B Lab Standards in its guidance on sustainability disclosures.

Investing in B Corp Certification is a way to demonstrate your commitment to better business and an opportunity to join a like-minded community working together to create systemic change.

Understanding the cost

From 2027, the total cost of B Corp Certification consists of three separate fees, namely, Application & Scoping Fee (where applicable), Annual IP License & Community Fee and an Independent Audit Fee. Discover the fees for B Corp Certification below.

Companies submitting in 2026 will pay 2026 fees. For more information on this pricing and applicability, see the 2026 fees here.

Application & Scoping Fee

The Application & Scoping Fee applies only to companies with both £10m+ in revenue and operational complexity that are pursuing B Corp Certification for the first time. The Application & Scoping Fee is invoiced by B Lab UK.

For operationally complex companies, B Lab supports you in determining the correct assessment track and certification scope, ensuring a streamlined and efficient audit experience with fewer delays or mid-process surprises. Most companies will be able to set up their assessment automatically on B Impact; this fee applies where a manual review is required.

£10m – £74.999m	£1,000	£0

The Annual IP License & Community Fee gives your company the ability to communicate your impact through use of the globally recognised B Corp logo. It provides access to a global ecosystem of purpose-led leaders, collaborative tools and opportunities to participate in community initiatives, learning activities, storytelling and campaigns.

This also contributes to B Lab's ongoing work to maintain and develop our standards and technology, and funds our mission—advocating for changes in policy and corporate culture that shift the global economy to a system that benefits all people and the planet.

Independent Audit Fee

The Independent Audit Fee covers the rigorous, unbiased evaluation conducted by accredited third-party assurance providers, To-Cert and SCS. Aligned with global ISO 17021-1 assurance standards, this phase goes beyond checking boxes; it provides a structured, multi-year review that validates your company’s impact and drives continuous operational improvement.

The fee applies to all companies ahead of a planned audit. A company’s audit fee and frequency are set and invoiced by the assurance provider and depend on the size, sector and complexity of your business. It only applies to the years in which audits take place within a 5-year certification cycle.

Use the calculator below for an indicative range. Your exact fee is confirmed once you submit your assessment. Prices are subject to change.

Independent Audit Fees are invoiced by the Assurance Provider and are outside B Lab’s direct control. The estimated ranges above are based on agreed pricing, the audit frequency model, and 2027 rates. Audit fees may vary depending on company complexity, structural changes during the process and preparedness. Travel expenses and VAT are excluded. Multisite Audit Fees are estimated by year. The Assurance Provider determines which sites are audited and when, so fees may arise earlier or later than shown across the five-year cycle.
