7 steps to certification
Becoming a B Corp is a rigorous but rewarding process. Our seven steps give you all the information that you need to become a B Corp, from pricing to eligibility all the way through to becoming part of the community.
Eligibility
Any for-profit company that has been operating for 12 months or more can become a B Corp. Find out more about our eligibility criteria.
Pricing
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. Eligible entrepreneurs who face systematic barriers to business ownership can receive a 40% discount on the annual fee.
The B Impact Assessment
Completing the BIA is the first step to certification. The tool helps you measure and manage your impact, and all B Corps must score 80+ to certify. Get started with the BIA.
B Corp Legal requirements
A big part of certification is known as the legal requirement. It involves amending your company's legal structure and/or articles of association to show your commitment to being a responsible business. By doing this, you can earn up to 10 points on the B Impact Assessment.
The review process
Once you've completed the BIA and Disclosure Questionnaire, you’re on the way to becoming a B Corp. The review process is conducted in two stages - Evaluation, led by B Lab UK, and Verification, led by B Lab Global. Find out more about it.
Reporting your impact
All certified B Corps in the UK need to write an annual impact report. Read our guide to find out how to get started.
