About STH Plumbing & Heating Ltd
STH Plumbing & Heating Ltd is a plumbing and heating business based in St Helens, established in 2008. The business carries out boiler servicing, boiler repairs on combi, conventional and system boilers, boiler installation, heating system work, bathroom installation, and general plumbing repairs. Services listed include radiator fitting, thermostat installation, power flushing, underfloor heating, gravity-fed cylinders, unvented hot water cylinders and solar hot water systems.
The business covers St Helens, Warrington, Wigan, Huyton, Prescot and Widnes. Work begins with a visit to assess the job and provide a quote. Boiler servicing involves careful checks to spot wear and efficiency issues. When faults appear, the engineers diagnose the problem and restore heating and hot water. For installations, a site survey assesses the property's heating demands before the right system is recommended. Installation is carried out to safety regulations and manufacturer guidelines. Bathroom projects are also undertaken alongside plumbing and heating work.
STH Plumbing & Heating Ltd is Gas Safe registered (539111) and a Vaillant approved installer. A member of WHICH Traders, the business is run by Chris Hammond. Completed heating work is supported by workmanship cover for a full year. Vaillant boilers are backed by 7 or 10-year manufacturer warranties where applicable. Quotes are available on request.
