Ipswich-based PLMR Genesis received the recognition for its verified commitment to high social and environmental standards.
Managing director Tim Miller said: “We’re extremely pleased to be recognised with B Corp certification.
“PLMR Genesis has a long and proud history in the East of England, and this achievement reflects the values that have shaped our work here for many years.
“This certification reinforces our commitment to making a positive and sustainable impact for our clients, our people and the communities we serve.”
B Corp certification is awarded by B Lab, a global non-profit that sets rigorous standards for social and environmental performance, transparency, and accountability.
The certification process is thorough and independently verified, assessing how companies create positive outcomes for people, communities, and the planet.
PLMR Genesis earned the certification as part of the wider PLMR Group, which was recognised for having an ‘Impact Business Model’, reflecting the nature of its client work for ‘Purpose-Driven and Underserved Enterprises’.
With a significant majority of the Group’s revenues coming from organisations such as schools, universities, charities, healthcare providers, public sector bodies and renewable energy companies – as well as other B Corps.
The announcement comes during a year of strong growth for PLMR Genesis.
The agency recently climbed 20 places in the 2025 PRovoke Global Rankings, marking its rising reputation in the UK and abroad.
Kevin Craig, founder and chief executive of PLMR Group, said: “The B Corp certification reflects the kind of business we have always set out to build at PLMR – one that delivers excellent work for clients and creates a supportive workplace where colleagues can thrive, all while making a positive contribution to society.
“We know that communications can shape debate, influence behaviour and drive meaningful change.
“We look forward to contributing our perspectives to the B Corp community over the years ahead and learning from others within it.”
