B Corp Certification Fees
To become a Certified B Corporation eligible companies must submit their B Impact Assessment, paying a submission and verification fee during the certification process, and then paying an annual fee as a member of the B Corp community.
Why do we charge for certification?
With urgent challenges facing our world, your contribution is vital to make business a force for good. Certification fees help sustain our work and accelerate change towards a better future for people and the planet.
From 2026, B Lab is introducing its new standards v2 which will bring a new certification process in which companies will be audited by a third-party assurer. This strengthens the credibility of the B Corp certification through the introduction of a streamlined and rigorous auditing system based on internationally accepted norms.
Despite this significant shift, B Lab UK has committed to freezing its fees through 2026 to support companies through the transition to the new standards. This means that companies submitting in 2026 for their first certification will pay the fees outlined below.
*The fees outlined below will cover only the initial Y0 HQ audit. Other fees linked to scoping and site audits (if required), and future audits are not included. New companies that do not complete certification successfully will still be required to pay a verification fee. Prices are subject to change.
How much does B Corp certification cost?
-
Submission fee
Once your assessment is submitted, a one-off tiered submission fee is payable. This covers the cost of a high-level review of the company’s assessment prior to verification and ensures the company’s commitment to the certification process.
-
Verification fee
B Lab UK charges a verification fee to cover the costs of a company’s audit. In 2026, we have frozen this fee which covers a company’s initial (Y0) HQ audit. This fee enables B Lab to keep up with growing demand and momentum of the movement, while maintaining the rigour of our verification process on our new standards.
-
Annual fee
For B Corps, annual fees are based on a company’s total revenue on the last set of audited accounts.

Fees for Large and Complex Companies
The above fees represent 2026 audit costs and annual fees that apply to the majority of companies completing the initial audit requirements. As each company differs in size, complexity and preparedness, it is not possible to publish fees that perfectly fit every case. The following fees may apply to multisite or large companies (companies above $75m in revenue or with over 250 employees). Please reach out to B Lab UK for more information.
-
Scoping fee—Large companies will be required to pay a scoping fee to cover the costs of creating their approved certification scope. If scoping shows that a company is less complex than its revenue suggests, B Lab UK will adjust the fee accordingly.
-
Site audit fees—Companies with multiple sites will require additional site audits at points during their 5 year certification cycle. Find out more about the site audit requirements on p. 31 here.
-
Company-related delays—In cases where additional time or work is required due to company-related delays, such as submitting incorrect documentation, missing deadlines, or providing incomplete information, B Lab UK reserves the right to charge for additional costs.
Our Commitment to Certified B Corps Headquartered in the UK
For B Corps required to recertify on the new standards in 2026, B Lab UK will absorb 100% of the costs of their initial Y0 HQ audit and associated technology fees to ease this quicker transition to B Lab standards v2. In addition, for more complex B Corps requiring site audits, B Lab UK will cover the costs of up to 4 required Y0 site audits. Find out more about the site audit requirements on p. 31 here.
This means that the only fee required in 2026 for all but the very largest B Corps will be the annual certification fee. While audit costs are set by independent assurance providers, B Lab UK remains committed to keeping certification costs affordable, transparent and consistent across Europe.

Equity pricing
We’re committed to building a diverse community of businesses while ensuring our movement remains inclusive and accessible. B Lab UK has equity pricing available to UK entrepreneurs facing systemic barriers to business ownership.
This means equity pricing (a 40% reduction in annual fees) will now be applied each year to all B Corps that are:
- <£5m annual revenue; and
- >50% ownership:
- People of colour and underrepresented ethnicities
- Women-owned
- LGBTQ-owned
- Disabled person owned
This is an evolution of our previous equity pricing and means more businesses will be eligible and remain eligible. It will be applied automatically but there is an opportunity to opt-out.
*For all newly certified and current B Corps that meet this criteria, the pricing will be automatically applied.
*Please note that all pricing and fee reductions are subject to change.
