What Spirax Group does

Spirax Group plc is a UK-listed FTSE 100 industrial engineering company headquartered in Cheltenham, with operations spanning nearly 70 countries, 33 manufacturing sites, and approximately 10,000 employees. The company operates three focused business segments: Steam Thermal Solutions (steam system components, boiler controls, traps, and valves), Electric Thermal Solutions (electrified industrial boilers and process heating for decarbonisation), and Watson-Marlow Fluid Technology Solutions (peristaltic pumps and fluid handling systems for process industries). Together these businesses deliver thermal energy and fluid technology 'total solutions' that improve operating efficiency and safety of customers' critical industrial processes, with a stated focus on enabling industrial transition to net zero through proprietary electrified heating technology.

The company serves enterprise customers across Industrial Manufacturing, Pharmaceutical and Healthcare, Food and Beverage, Chemical Processing, and Energy. Its new-to-world decarbonisation solutions — proprietary electrified boilers and process heating systems — eliminate scope 1 and 2 greenhouse gas emissions when connected to green electricity, positioning the product roadmap at the intersection of industrial efficiency and ESG capex demand. Spirax has adopted Autodesk Fusion Manage as a cloud PLM platform to standardise processes across global manufacturing and has partnered with Microsoft to accelerate its digital and AI strategy.

Spirax makes money primarily through direct B2B sales of engineered equipment, aftermarket components, and associated services, with quote-based pricing and multi-year contracts. Pricing is not publicly disclosed and varies by application and scope. Reported FY2025 revenue was £1,702.9 million with 5% organic growth and an adjusted operating profit of £339.9 million (~20% margin). Revenue is split across three streams: Thermal Energy Solutions (steam and electric thermal equipment and services), Fluid Technology Solutions (Watson-Marlow pumps and fluid handling), and Digital and Services. The company distributes exclusively through direct industrial sales, supported by a global field service and engineering footprint.

Core offering

Spirax Group designs, manufactures and sells proprietary thermal energy and fluid technology solutions for industrial customers through three businesses: Steam Thermal Solutions (steam traps, controls, valves and boiler systems), Electric Thermal Solutions (electric boilers and electrified process heating for decarbonisation), and Watson-Marlow Fluid Technology Solutions (peristaltic pumps and fluid handling systems). Its new-to-world decarbonisation solutions use proprietary technologies to electrify boilers for steam raising and electrify other critical industrial process heating applications.

Product overview

Spirax Group is a diversified industrial engineering company operating three distinct business segments: Steam Thermal Solutions, Electric Thermal Solutions, and Watson-Marlow Fluid Technology Solutions (WMFTS). The company provides total thermal energy and fluid technology solutions that improve the operating efficiency and safety of customers' critical industrial processes. Its portfolio includes steam system components (traps, controls, valves), electric heating solutions for decarbonisation, and peristaltic pump/fluid management systems. The three businesses are united under the Together for Growth strategy, offering complementary capabilities in thermal energy management and fluid handling across industrial applications.
