Improving your score - B Lab UK

Improving your BIA score

B Corp certification requires a B Impact Assessment score of 80+ points. It’s rare to achieve this first time and most businesses will spend time improving their score. 

Completing the Assessment and the 80+ point threshold

Completing the Assessment is different for every company and while scoring is intentionally rigorous, you should aim to submit with a score of around 80-85 points.

To become B Corp certified, your company must first complete the B Impact Assessment, the free, online platform used by B Lab to measure your social and environmental performance impact.

Crossing the 80-point threshold doesn’t usually happen at the first pass, but improving your business’s impact is made easier thanks to a range of tools and resources built into the B Impact Assessment.  These show which impact areas your company already excels in, how your practices compare to other businesses and which it could improve on. 

Best practice guides, case studies and other dynamic tools will help you create a clear roadmap, set goals for improvement, and track your performance over time.

Tools to help you within the Assessment

A number of tools are built into the B Impact Assessment to help guide you through the initial application and to help you identify and implement improvements.

‘Quick Wins’

As you set out to improve your impact score, a great place to start is by formalising your company policies and tracking key metrics across the 5 Impact areas measured in the BIA.

For example:

  • Writing and circulating a Supplier Code of Conduct (Community)
  • Monitoring and recording energy, water and waste usage (Environment)
  • Writing a policy or statement to support breastfeeding mothers (Workers)
  • Sharing financial information with employees (Governance)
  • Improving the transparency and clarity of your Data and Privacy Policy (Customers)

Make it legal

Adopting the B Corp legal requirement will earn you from 7.5 - 10 points on the B Impact Assessment, by locking in your mission to put people and planet alongside profit.

Get support from your team

Appoint one person as a lead to complete the initial Assessment and engage support from employees across your whole business (even external stakeholders) to help identify areas where you can make real, lasting improvements and impact.
