Blackburn-based PM+M has achieved Certified B Corporation status.

Verified by B Lab, the not-for-profit behind the B Corp movement, the achievement demonstrates that the chartered accountancy, business advisory and financial planning group meets high standards of social and environmental performance, transparency, and accountability.

B Corp certification is awarded by B Lab and assesses the entirety of a business’ operations and covers impact areas related to practices around governance, workers, community, the environment and customers.

The certification process is rigorous, with companies required to provide evidence on performance while legally embedding their commitment to purpose as well as profit in their company.

PM+M is only the second North West headquartered accounting firm to achieve B Corp Certification, and one of just 25 accountancy firms across the UK to do so – a rare achievement that underlines the firm’s commitment to driving positive impact within its profession and community.

Founded in 1919, PM+M delivers a range of services across audit and accounting, corporate finance, cloud accounting, payroll, business and private client tax, financial planning and mortgages.

Helen Clayton, managing partner at PM+M, said: “Becoming a Certified B Corporation reflects the way we have always tried to do business which is putting our people, our clients and our community at the heart of every decision whilst consistently delivering an outstanding service.

"Certification is a milestone, not a finish line, and we’re excited to keep raising the bar. We are determined to always use business as a force for good."

Helen added: “Certification means that PM+M’s practices, and our commitment to stakeholder governance, is world-leading and that is something myself and the whole team are immensely proud of.

"Moving forward, we will be striving for continuous improvement, we are committed to recertification, and we will use the B Corp framework to benefit Lancashire and the wider North West region.”

Chris Turner, executive director of B Lab UK, said: “We are delighted to welcome PM+M to the B Corp community.

"This is a movement of companies that are committed to changing how business operates and believe business really can be a force for good.

"We know that PM+M is going to be a fantastic addition to the community and will continue driving the conversation forward.”

 PM+M is now part of a growing community of over 9,700 businesses globally that have certified as B Corps.

The B Corp community in the UK is one of the largest and fastest-growing in the world, with over 2,500 companies spanning a range of different industries and sizes.

Names include The Guardian, Innocent Drinks, The Big Issue, Elemis, and Sipsmith Gin.
