Irwin Mitchell: Law firm with 1,200 staff in Yorkshire delivers revenue growth
The law firm Irwin Mitchell has revealed it achieved revenue growth during a year of “strategic investment”.
Irwin Mitchell, which employs 1,200 staff in Yorkshire across offices in Sheffield, Leeds and Aske, reported a 6.4 per cent increase in revenue to £337.5m in the year ending 30 April 2026. A spokesman said this was a period when the firm invested in its core legal services and strengthened its national footprint.
Underlying profit before tax from trading activities was £16.5m, compared with £22.4m in the previous year, which the firm said reflected planned significant one-off investments in technology, an increase in national insurance contributions due to UK tax changes and several office moves across locations including London, Brighton, Liverpool, Cardiff and Nottingham.
The statement added: “The investment made in the year is expected to drive future growth and profitability.”
It continued: “Irwin Mitchell has continued to progress its strategy of focusing on higher value complex legal work and the firm’s international revenue more than doubled to £35.4m, reflecting growing strength in cross-border and specialist advice for both businesses and private clients.
"International work now represents more than 10 per cent of revenue, leveraging key client relationships and international law firm partnerships.
"The firm also received a prestigious King’s Award for Enterprise for its work supporting international trade by advising overseas businesses investing in the UK.”
"The firm has focused on its core legal services in recent years. It is the market-leader in complex personal injury and medical negligence, has one of the largest specialist private client teams in the UK and has a fast-growing business services team focused on mid-market corporates.”
Over the year, Irwin Mitchell completed the sale of IM Asset Management and the Ascent debt management business, which it described as “supporting a sharper focus on core legal services”.
It also announced plans to relocate the Sheffield teams, who are based in the firm’s largest office, later this year.
Craig Marshall, Group Chief Executive Officer at Irwin Mitchell, said: “This has been an important year for Irwin Mitchell. We have continued to grow revenue while making disciplined long-term strategic decisions to strengthen our business, invest in our people and infrastructure, and focus on the areas where we can make the biggest difference for our clients.
“We remain a diverse legal business serving individuals and businesses across the UK and globally, but with a clearer focus on complex, specialist advice.
"The progress we have made this year reflects the strategic direction of travel we have set over recent years and gives us a strong platform for sustainable growth in the years ahead.”
