What Flexigas does

Flexigas is a UK manufacturer of corrugated stainless steel tubing (CSST) gas pipework systems, trading as a brand of Flexiridge Ltd (part of the Flexipipe group) and operating from Somerford Booths, Cheshire. Founded in 2016, the company sells a BSI Kitemarked system certified to BS EN 15266:2007 (Kitemark KM 598726, licence valid to 11 July 2027), comprising 316L stainless steel flexible tubing in DN15 to DN50 sizes supplied in coils from 15m to 400m, 130+ brass fitting codes, the proprietary FG Bond integrated earthing terminal (BS 951:2009), and the Flexigas DS double-sleeve variant. The core technical differentiation is a proprietary metal-to-metal dry seal — the corrugated tube self-flares against a brass seat with no solder, flux, jointing compound, or hot works — and a kit-level certification that is voided if mixed with other CSST brands.

The company's go-to-market is a pure channel-partner model: products are sold exclusively through a network of 370+ UK merchant branches anchored by national chains (Plumbase 138 branches, Graham 61, HPS 41) plus regional independents, with installers ordering by product code at the counter. Flexigas supports the channel with trade-morning training sessions at merchant branches, a free in-browser sizing calculator (also available as native iOS/Android apps), downloadable technical documentation, and a UK-based technical support team reachable by phone and email. Pricing is set per merchant branch and is not publicly disclosed. End customers are Gas Safe registered installers working on domestic and light-commercial gas jobs, with secondary segments in merchant counter staff and construction specifiers; the sister brand Ridgeline extends the corrugated 316L stainless platform into water plumbing from the same engineering base.

Flexigas is a privately held single-country operation with 13 employees, no disclosed external funding, and no announced M&A. Its value proposition rests on regulatory certification (BSI Kitemark), standards-committee participation by its technical director, and installer- and merchant-channel depth rather than on technology platform scale or proprietary software, leaving the business fundamentally a niche specialist manufacturer with a strong distribution moat in UK gas pipework.
