Forvis Mazars advises on the partnership between BHP and Sumer Group

BHP LLP, one of Yorkshire’s largest independent accountancy firms, has joined Sumer, the UK’s fastest-growing mid-market accountancy practice.

Founded over 150 years ago, BHP has grown into a 400+ employee firm, with offices in Sheffield, Leeds, York, Cleckheaton, and Chesterfield. The firm has a long-standing reputation for supporting entrepreneurial and owner-managed businesses, offering audit, tax, corporate finance, and advisory services to thousands of SME clients across the region.

The deal establishes BHP as Sumer’s new Yorkshire hub, strengthening the group’s national footprint and providing fresh investment to accelerate their growth across Yorkshire and the wider North of England.

Forvis Mazars acted as lead M&A advisor to BHP LLP, supporting them throughout the transaction process and helping to secure a successful partnership with Sumer. The transaction further underlines Forvis Mazars’ capability in the professional services sector and in advising clients on private equity transactions.
