Sumer

In 2019, Warren Mead and Nigel Carr recognised a gap in the UK accountancy market. While small and medium-sized enterprises power the British economy and connect local communities, they often lack access to the same calibre of professional services available to larger corporations. The founders saw an opportunity to change this by bringing together the best regional accounting practices under one national organisation - combining local expertise with the scale and technology of a large firm.

Today, Sumer has grown to become the fastest-growing accountancy firm in the UK and Ireland, serving over 60,000 SME clients across more than 80 offices. The company unites renowned regional practices including BHP, Carpenter Box, Cowgills, DPC, EQ Accountants, HW Fisher, Jerroms, Monahans, Moore Thompson, RMT, Scrutton Bland, Simmons Gainsford, and Sumer NI. Each firm maintains its local identity and expertise while benefiting from the group's national resources, advanced technology, and shared success model. Warren Mead continues to lead as CEO, championing the businesses at the heart of local communities while driving the group's ambitious expansion strategy.
