Accountancy group Sumer has expanded in the East of England through the acquisition of an established accountancy and advisory practice. Moore Thompson is a longstanding firm with offices across the East Midlands and East of England.
Operating for more than a century, Moore Thompson advises SMEs, family-run businesses and charities, with a significant proportion of its client base being agricultural and rural organisations. The firm has offices in Spalding, Wisbech, Market Deeping, Peterborough and Stamford.
As well as strengthening Sumer’s presence in the East of England and East Midlands, the deal increases the group’s capacity to serve clients across agricultural and land-based enterprises.
The acquisition brings several new offices into the group across key rural and market-town economies, building on its existing hubs in the North East (RMT Accountants), Yorkshire (BHP) and East Anglia (Scrutton Bland). Moore Thompson also brings a workforce of approximately 100 staff.
Sumer Chief Executive called Moore Thompson “a trusted and respected practice with deep roots in the community”, adding that Managing Partner Mark Hildred and the rest of the team had built a firm with strong client relationships and an approach that closely aligns with Sumer’s.
Calling the deal a “hugely positive step” for Moore Thompson, its staff and clients, Mark Hildred said: "We're proud of our heritage and the personal relationships we've built over many decades. Becoming part of Sumer allows us to retain everything that makes Moore Thompson special, while giving us access to wider expertise and new services which will benefit our clients.”
He added that the deal would enable the company to support even more businesses across the East of England.
In the year to June 30 2024, Sumer Group Holdings Limited reported turnover of around £71.1 million, up from £6.8 million in the period from July 26 2022 to June 30 2023, following a year in which it expanded from three hubs to ten. Normalised EBITDA, meanwhile, increased from £1.4 million to £15.8 million.
Having continued with its rapid acquisitive growth since then, Sumer says it now generates revenue of close to £300 million, with around 3,000 staff working across 70 locations.
