What Stuart Turner does

Stuart Turner Limited is a UK-based manufacturer specialising in domestic and commercial water boosting solutions, operating as a wholly owned subsidiary of Fluid Water Group. The company designs, manufactures, and distributes shower pumps, whole home boosting systems (including the MONSOON PROFESSIONAL variable speed range and MAINSBOOST, iBOOST, and STORMBOOST product lines), circulators, mixers, and catalytic-magnetic water conditioners. Core technology centres on variable speed centrifugal multistage pumps with intelligent pressure control, automatic protection systems, and proprietary catalytic alloy water conditioning cores, with WRAS, Kiwa, CE, and UKCA certifications. The group employs approximately 230 people across four UK manufacturing sites (Henley-on-Thames headquarters, Eggborough, Redditch, and Colchester/Manchester) and reports annual turnover in excess of £60 million.

The company operates a hybrid go-to-market model. The primary commercial channel is indirect, selling through national merchant chains (Screwfix, Toolstation, Plumbase, City Plumbing, Anchor Pumps) and regional independent stockists to professional installers and plumbers. A secondary channel reaches homeowners directly via the company's website, whole home boosting survey, and TechAssist technical support, then funnels them to approved installers. The Installer Club loyalty programme, with points-based rewards, Approved Installer training at stadium venues, and warranty registration privileges, is central to deepening trade relationships. Three wholly owned subsidiaries — Stuart Turner Aquaboost (commercial and OEM water boosting), Mikrofill Systems (commercial condensing boilers and pressurisation equipment), and Aquatronic Group Management (installation and maintenance services) — extend the addressable market into commercial, OEM, and aftermarket service segments.

Customer segments split between residential homeowners experiencing low water pressure in older or rural properties, trade installers and plumbers who specify and fit products, and commercial/OEM buyers requiring high-capacity boosting solutions. Pricing is not publicly disclosed; consumer products are purchased through stockists at retail, while commercial and whole home systems are quoted directly by the sales team. The business is privately held with no external funding rounds disclosed, indicating self-funded growth under Fluid Water Group ownership.
