Monahans became part of the Sumer Group in 2023.
Sumer is one of the UK’s leading accountancy and business advisory groups, bringing together established regional firms from across the country.
Founded with a commitment to championing small and medium-sized businesses, Sumer was created to support the organisations that drive local economies and communities across the UK. By bringing together successful regional firms, Sumer combines local knowledge and relationships with the scale, investment and specialist expertise needed to support businesses as they grow and evolve.
Today, Sumer includes more than 50 offices and thousands of colleagues across the UK, providing expertise across accountancy, tax, audit, payroll, HR, corporate finance, wealth planning and business advisory services.
Sumer is currently ranked 12th in the UK Top 50+50 Accountancy Firms league table and is recognised as one of the fastest growing accountancy groups in the UK.
Rather than operating as a single national firm, Sumer is built around successful local businesses that continue to serve their communities under their own brands. This allows firms to retain their local presence and identity while benefiting from wider collaboration, shared expertise and investment.
For Monahans clients, this means continued access to the people and teams they know, alongside the broader expertise and resources available across the wider Sumer Group.
