Its offices are located in Chichester, Guildford, the Isle of Wight, Salisbury and Southampton.

With a team of 92 people across its locations, Moore South serves a client base that includes owner-managed businesses (OMBs), entrepreneurs, individuals and larger organisations operating in the UK as well as in overseas markets.

Moore South managing partner Danielle Griffin said: “We have been collaborative partners with Moore Kingston Smith for many years, which speaks to our shared priority of understanding our clients’ needs.

“By merging, we can further support our clients in achieving their goals, providing them with streamlined and integrated access to Moore Kingston Smith’s range of specialist services, while maintaining the close, long-standing relationships we have with local businesses.”

Following completion of the deal, Moore South’s employees and partners will become part of a broader Moore Kingston Smith platform.

The combined group will comprise more than 120 partners and 1,600 employees across the UK and Ireland.

The companies said the merger will widen the advisory offering available to clients and provide easier access to specialist services across multiple regions.

Moore Kingston Smith managing partner Matt Meadows said: “This marks an exciting evolution, seeing us become a truly multi‑regional business in England, adding to our other recent acquisitions including those in Ireland and Northern Ireland.

“Moore South’s long‑standing relationships with start-ups, family‑run firms and regional OMBs represent a strong strategic fit with our approach.

“Together, we can double down on our collaboration, and the international strength of the Moore Global network, in a more formal and joined-up way.”

In January, Moore Kingston Smith announced several senior-level hires and promotions across its UK offices.
