Irwin Mitchell is unlike any other law firm. Nationally acclaimed, with a strong international capability, we offer a broad range of legal services to national and international organisations and institutions, small and medium-sized businesses and private individuals.
The firm was founded in 1912 by Walter Irwin Mitchell. With a concentration on criminal law, he aimed to provide the highest quality legal services to the general public from his small legal practice in Sheffield.
Today, Irwin Mitchell is the 11th largest law firm in the UK with one of the five largest Private Wealth teams in the country, operating out of 15 UK offices including a consulting office in Middlesbrough.
We currently employ over 2,500 members of staff, including over 1,000 legally trained personnel and have helped over one million clients in our 100 year history.
The Business Legal Services division is also the fastest-growing area of the firm, with an increasing number of global, national and regional companies choosing to work with us.
In 2012, we became one of the first companies to be approved as an Alternative Business Structure (ABS), allowing us to plan for growth and take advantage of the opportunities created by the changing legal landscape.
In 2018, we joined First Law International (FLI), a global network of over 80 independent national law firms, as part of our on-going effort to increase our international presence and support our international growth.
Whenever you deal with us, you’ll notice that our core values guide us at every stage. We always seek:
To be pioneering with an imaginative outlook
To be approachable and caring
To be tenacious in the pursuit of our objectives
To be efficient in the provision of our services
