One Group Construction

What One Group Construction does

One Group Construction is a privately-held UK holding company headquartered in Ipswich, Suffolk, operating since approximately 1955 as the parent of nine wholly-owned subsidiaries: Jackson Civil Engineering (nationwide infrastructure), SEHBAC (home improvements, windows, doors, conservatories), SEH Ipswich (civil engineering and residential infrastructure in East Anglia), SEH French (commercial and residential construction), SEH Asphalt (road and infrastructure surfacing), SEH Developments (residential and commercial property development), Emmitt Plant (plant hire, sales and maintenance), Anchor Freight (freight management and worldwide logistics), and Padel Ipswich (sports and leisure).

The group operates no proprietary technology platform; its competitive position rests on industry certifications (ISO 9001/14001/45001, Constructionline Gold, CHAS, NHBC, RISQS, FENSA), long-tenured operational leadership, and 70+ years of accumulated credentials in UK infrastructure delivery. There is no disclosed AI, software, or digital product offering — operations are project-based construction, logistics and physical retail/leisure services.

One Group Construction generates revenue through project-based construction contracts, direct retail home improvement sales (SEHBAC), freight forwarding transactions (Anchor Freight), plant hire (Emmitt Plant), and consumer leisure bookings (Padel Ipswich). Pricing is quote-based across B2B/B2G contracts and direct consumer sales. The group serves three customer segments — government departments (notably the Environment Agency under a 20+ year framework), private sector organisations, and retail consumers — with deliberate diversification across subsidiaries to limit exposure to any single client, sector or geography.
