Thu, 12 Feb 2026 | MERGER
Real estate advisory firm SHW has announced a merger with an independent property consultancy operating across Kent and West Sussex. The integration with Karrison Property will be headed by SHW Director Thomas Tarn.
Karrison Property has a portfolio spanning retail, office and industrial properties, with a client base that includes commercial occupiers, high-net-worth individuals, pension funds and family-owned trusts. The company also works with specialist assets, such as a family-owned wine estate in Westerham.
The merger will see East Sussex-headquartered SHW take on responsibility for Karrison’s existing commercial leasing agency instructions across its portfolio. The deal will also give Karrison’s client base access to SHW’s full-service advisory offering, spanning professional services, building consultancy, property management and agency.
Russell Markham, Managing Partner at SHW, commented: “This latest alignment allows us to significantly expand our operations across Kent and West Sussex, taking on a strong, established agency portfolio while extending our wider advisory expertise to an expanded client base.”
The merger with Karrison Property continues a period of growth for SHW, following the firm’s recent expansion across Surrey through a new strategic partnership with Lambert Smith Hampton. The latest deal reflects the firm’s continued focus on securing regional growth across the South East of England.
