What Dunphy Combustion does

Dunphy Combustion Ltd is a UK-based, privately held designer and manufacturer of industrial combustion equipment founded in 1964 (operating under the Dunphy Combustion brand since 1971) and headquartered in Rochdale, with 51-100 employees. The company engineers, produces, installs and maintains a portfolio that spans industrial burners (hydrogen, renewable fuel, multi-fuel, oil and biogas variants), industrial boilers (steam, hot water, electric, thermal oil), digital boiler house control systems, gas boosters (Simplex/Duplex/Triplex), and prefabricated packaged plant rooms built off-site in its Rochdale factory complex. Its core technology emphasises ultra-low NOx performance and multi-fuel flexibility; the company holds UKCA and CE certification for 100% hydrogen combustion and all blends with natural gas, and received the King's Award for Enterprise in Innovation 2025 for an advanced low NOx multi-fuel burner that can switch between hydrogen and natural gas.

Revenue is generated primarily through hardware sales of burners, boilers, control systems, gas boosters and packaged plant rooms, supplemented by recurring income from a global spare parts operation (~20,000 SKUs, most delivered within 24 hours), installation and commissioning, planned contract maintenance, statutory inspections, burner upgrades and accredited training (industrial boiler, steam and BOAS courses). Go-to-market is direct enterprise field sales to industrial customers in the UK manufacturing sector, supported by field service engineers coordinated from the main factory. Pricing is quote-based and not publicly disclosed, reflecting bespoke configurations tied to site space, fuel feeds and process requirements.

The company is independent, with no identified parent, private equity or venture capital backing, and no subsidiaries; customer logos are not publicly disclosed. Its competitive position leans on long operating history, three royal awards for innovation (1998, 2010, 2025) and first-mover regulatory certification for hydrogen blends, while its growth signals concentrate on decarbonisation-aligned product launches and global spare parts distribution rather than funded expansion.
