Becoming a B Corp: what the certification could mean for your business
September 7, 2026
For companies considering certification, it is important to understand what the process involves and the practical commitments that come with achieving B Corp status.
Our corporate law expert, Siobhan Johnson, outlines what B Corp certification is, the steps businesses need to take to become certified and the advantages and disadvantages of certification.
B Corp certification has become one of the most recognised ways for businesses to demonstrate a commitment that commercial success and social responsibility can go hand in hand. At its core, B Corp certification encourages businesses to consider the interests of a wider range of stakeholders, including employees, customers, suppliers, local communities and the environment, as well as shareholders. However, certification is far more than a badge of approval. Businesses must undergo a detailed assessment process, implement governance changes and commit to ongoing reporting to achieve and maintain their B Corp status.
The certification process can generally be broken down into three key stages.
The starting point for any business seeking certification is the B Impact Assessment, which will assess areas such as governance, workers, community, environment and customers. Businesses should be prepared to provide detailed supporting evidence and documentation throughout the review process. Once submitted, the assessment is reviewed and verified by B Lab UK. The process generally involves several stages, including an evaluation queue, review by a B Lab analyst, document verification and final certification approval. To qualify for certification, a business must achieve a minimum verified score of 80 points.
Businesses must also incorporate B Lab’s legal requirement into their constitutional documents. For most UK companies limited by shares, this means amending their Articles of Association to include wording prescribed by B Lab. The purpose of the amendment is to strengthen the way directors consider stakeholder interests when making decisions.
Once the impact assessment has been verified and the legal requirement has been satisfied, the final step is to enter into the B Corp Agreement and sign the Declaration of Interdependence. The B Corp Agreement sets out the terms of certification, annual fees and the ongoing obligations placed on certified businesses. The Declaration of Interdependence reflects the wider philosophy of the B Corp movement, committing businesses to create a positive impact through their products, practices and profits.
There are a number of reasons why businesses choose to pursue B Corp certification.
For many businesses, it offers credibility in terms of ESG commitments. It can help businesses differentiate themselves in competitive markets and demonstrate that social and environmental considerations form part of their decision-making. The certification process can also encourage businesses to review their policies, governance structures and reporting processes.
However, certification is not free. Businesses are required to pay application and certification fees, with annual fees generally increasing according to the size and revenue of the business. The B Impact Assessment is detailed and evidence-based, often taking several months to complete. B Corp certification is not a one-off exercise and businesses are expected to continue measuring and reporting on their impact to maintain their status.
B Corp certification can be a valuable framework for businesses looking to formalise their commitment to responsible business practices, strengthen governance and demonstrate their values to customers, employees and investors.
