Marrons Achieves B-Corp Status

Planning | News
Planning and design consultancy Marrons – as part of legal and professional services group Ampa – has been awarded B-Corporation certification. 

Organisations with certified B-Corporation status are legally required to consider the impact of business decisions on their people, customers, suppliers, communities and the environment, ensuring a balance between purpose, people and profit.   

The benchmarks in order to achieve accreditation are incredibly high and the auditing process is rigorous, with non-profit B-Lab independently scoring companies across governance, workers, community, environment and customers to determine the business’ social and environmental performance.    

Brian Mullin, head of Marrons, said: “This is a key milestone in our drive to align with B-Corporation ambitions and values with our business.  B-Corporation values are embedded in our business strategy, championed by our management structure and fully supported from the top-down. We take great pride in helping our clients achieve sustainability goals.   

As we continue to grow our business and enhance the reputation of our brand across the UK, we are looking for likeminded professional services brands to join Marrons within the wider Ampa group. Ampa has been highly supportive of Marrons’ growth and we are collectively committed to achieving more success in the right way. Integral to that is reaching for the highest possible level of social and environmental responsibility.”  

As well as Marrons, Ampa also includes brands Lime Solicitors, Shakespeare Martineau, Mayo Wynne Baxter, CSS Assure and Corclaim, employing more than 1,300 people over 18 hubs across the UK. 

Helen Hay, group head of culture and sustainability at Ampa, said: “This is a huge achievement for us and demonstrates our commitment as a group to use business as a force for good for our people, planet, communities and clients.  

We’re really proud to have achieved our highest score for how we treat our people, including our approach to pay and reward, our wellbeing initiatives and benefits and embedding professional development support and opportunities across the group of brands.  

We keep ourselves accountable through our responsible business ambitions that are constantly tracked and analysed, pushing us to do better and achieve more. So far, we have achieved a number of our ambitions across diversity and inclusion, reducing landfill waste and carbon emissions, as well as supporting young people in our local communities.”  

Among other ambitions, in 2022 the group increased racial diversity at a membership (equity stakeholder) level by more than 3%, against a target of 2%, supported more than 400 young people through a variety of career development events, and significantly reduced its paper use. As part of the rigorous auditing process, Ampa achieved its top score for its commitment to employees and full marks for its group-wide intern programme.
