Initial steps of becoming a B Corp
B Corp Certification is unique because it measures a company’s entire social and environmental performance. From supply chain and input materials to charitable giving and employee benefits, B Corp Certification verifies that a business is meeting high standards of social and environmental performance, transparency, and accountability.
Who can certify?
You can certify as a B Corp if you operate for profit in a competitive market, and have at least 12 months of operations.
How much does B Corp Certification cost?
Using the B Impact Assessment is free. 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.
We have subsidised the verification fee for the smallest companies wanting to join our community. In this way, and alongside our new equity pricing, we are continuing to ensure the B Corp movement remains a home for diverse businesses of all shapes and sizes.
