About

The firm: Irwin Mitchell are legal and financial experts that care. As one of the largest full-service law firms in the UK, they’ve supported over one million clients and counting. Whether it’s personal or business, they understand that everyone’s situation is different. They offer 24/7 client care, ensuring their clients are at the centre of what they do.

Founded in 1912, they’ve grown from a small building in Sheffield, to offices in 18 locations across the UK and a global reach that extends to over 200 countries. With over 3000 staff and 180 services, their vast experience and knowledge is complemented by their dedicated approach to client care. Whether it’s settling a case before trial, or succeeding at the Supreme Court, it’s all about the results they achieve when it matters, and the relationships they develop along the way.

The firm recently invested in Scottish law firm Wright, Johnston & Mackenzie to increase their market share North of the border. They followed this up with the acquisition of Silk Family Law, demonstrating their ambitions in the Northeast of England. Their asset management division also expanded its wealth management team and capabilities with the purchase of TWP Wealth.

Their commitment to being responsible goes further than the law and they have donated over £3m to charitable causes since 1997. In 2023, their colleagues completed over 6,000 hours of volunteering. They are the only law firm to be named in the top 25 Great Places to Work in the UK (five years running) and rank in the top 20 UK’s best workplaces for women. The firm was recently named as one of the Best UK Workplaces for Wellbeing and was awarded a Gold Award in the Defence Employer Recognition Scheme.

They’re recognised in The Times’ list of the best law firms in England and Wales and The Lawyer magazine named them as ‘a litigation powerhouse’. They were recently recognised as the number one Superbrand in the legal sector and are the Official Legal Partner to England Rugby, British Rowing and UK Athletics.

Market: As the leading personal injury and medical negligence practice in the UK, Irwin Mitchell helps thousands of families whose lives have been turned upside down. Supported by a national Public Law team and the UK’s leading Court of Protection practice, they offer help and reassurance during the hardest times.

Irwin Mitchell’s private client offering specialises in residential property, family, Wills, tax, as well as trusts and estate disputes. They protect high and ultra-high net worth individuals, including business owners and entrepreneurs, corporate executives, investors, and multi-generational families.

This is supported by a full suite of business services for corporate clients and institutions such as litigation, corporate, commercial, international property and employment law. They offer tailored guidance to businesses when it comes to navigating environmental, social and governance, and are part of First Law International - a global network of more than 80 law firms.

This is all bolstered by IM Asset Management, a fast-growing financial planning and wealth management service with more than £1.2bn assets under management, and Ascent - their debt recovery subsidiary company which works with major financial institutions and organisations.
