SThree

London-based recruiter focused on contract STEM roles

Overview

SThree plc is a London-based global recruitment firm focused on science, technology, engineering and mathematics (STEM) roles.[18] For the year ended 30 November 2025 it reported revenue of £1,302.2 million and net fees of £322.7 million, each down 13% as reported and 12% like-for-like.[7][18] Contract placements produced 84% of net fees and permanent placements 16%.[18] DACH (Germany, Austria and Switzerland) was the largest region with £106.6 million of net fees, followed by the USA (£83.1 million, the only region to grow, up 4%), the Netherlands and Spain (£62.2 million), the rest of Europe (£51.5 million) and the Middle East and Asia (£19.1 million).[18]

SThree’s emphasis on contractors distinguishes it from permanent-weighted recruiters such as PageGroup and Robert Walters: contract assignments provide recurring fees while a placement lasts, which can make revenue more stable through hiring slowdowns, though 2025 still brought a double-digit decline.[7] For employers, SThree is a specialist option for STEM contractors and permanent hires; it is less suited to general business or executive-level recruitment.
