Swish Building Products, part of the Epwin Group, has secured an Environmental Product Declaration (EPD) for its Kayflow and Swish Specification rainwater product lines. The certification covers the complete lifecycle environmental impact of both ranges.
EPDs are increasingly requested by architects and developers during tender and specification stages. Market demand for such declarations has risen across UK construction over the past three years as sustainability criteria embed deeper into procurement workflows.
The accreditation allows Swish to address enquiries from specifiers requiring independent environmental data. EPD-certified products now differentiate suppliers in tenders where environmental performance statements have become standard evaluation criteria alongside cost and performance metrics.
For installers and merchants stocking the Kayflow and Swish Specification ranges, the EPD provides specification ammunition when presenting these products to architects and main contractors. Whether the certification delivers measurable market advantage depends on how widely the sector adopts EPD requirements—currently adoption remains patchy across UK housebuilders and mechanical contractors.
