Spiral UK

What Spiral UK does

Spiral UK is a UK-based bespoke staircase manufacturer operating under the legal entity Spiral Construction Limited, founded in 1985 and headquartered in Helston, Cornwall. The company designs, fabricates, and installs staircase structures across four primary types — spiral, cantilever/floating, helical/curved, and straight (including dog-leg and spine beam) — serving three market segments: commercial (office fit-outs, public buildings, retail; the primary segment), residential (luxury homes), and escape staircases for fire and emergency egress. It holds ISO 9001 quality certification, Constructionline, Achilles, and Builders Profile accreditations, and all steelwork is supplied to CE Execution Class 2 EN 1090, with designs compliant with BS5395 Part II and UK Building Regulations Parts K, M, and B.

Operations are fully vertically integrated in-house: a small team of four SolidWorks/AutoCAD design engineers produces fabrication packs, metalwork is fabricated in the Cornwall facility (welding, powder coating, galvanising), and dedicated installation crews fit the staircases on site without subcontracting. The business runs a quote-based bespoke model, with residential projects starting from £10,000 and pricing driven by complexity, dimensions, materials, and finishing. Go-to-market combines direct sales engagement from offices in Cornwall and Cambridgeshire, CPD presentations to architects and contractors, downloadable brochures, social media, and Google AdWords remarketing. Named enterprise customers include Dyson, European Space Agency, Sony Interactive, Great Portland Estates, Enterprise Holdings, BrewDog, and Carbis Bay Hotel, with strategic fit-out channel partners including Overbury Plc and Area. In 2025 Spiral UK transitioned to employee ownership, and Eric Nicholls serves as Managing Director.
