Brett Martin

What Brett Martin does

Brett Martin is a privately held UK plastics manufacturer founded in 1958 and headquartered at Newtownabbey, Northern Ireland, operating through three divisions: Plastic Sheets, Daylight Systems, and Plumbing & Drainage. The company manufactures polycarbonate, foam PVC, acrylic, PETg, and aPET sheets under sub-brands including Foamalux, Marlon, Marcryl, and Marpet-g; industrial, dome, glass, and vaulted rooflights plus panel glazing systems under the Mardome and Marlon Clickfix VF ranges; and underground drainage, rainwater, and soil & waste systems including the StormCrate55 geocellular unit and Cascade cast iron style rainwater range. Core technology centres on thermoplastic extrusion and injection moulding at four UK production sites (Newtownabbey, Coventry, Staveley, Burscough) plus a US joint-venture plant in De-Pere, Wisconsin established in 2025. Coventry alone produces over 700,000m² of rooflights annually, and Newtownabbey houses one of the largest polycarbonate extrusion facilities in Europe. All production facilities operate to BS EN ISO 9001:2015, with Coventry also holding ISO 14001, and the range carries 250+ product certifications including British Board of Agrément (BBA) approval and Secured by Design accreditation.

The business sells through a multi-channel model: unit-priced B2B shipments via UK and Ireland builders' merchants (primary route for plumbing and drainage), regional distribution hubs (Luton, Cumbernauld), an Approved Partner Programme of 13+ printing and cutting equipment OEMs, and direct regional sales teams for daylighting specification. Customers span construction, industrial buildings, sign and display, housebuilding, agriculture, and commercial drainage. More than 40% of revenue is generated in export markets across 70+ countries, with explicit £100m+ in exports cited. Leadership remains in the founding family (W. L. Martin as Chairman & Managing Director) and the company operates without external institutional or private equity ownership.

Revenue mechanics are one-time product sales with quote-based pricing through merchants and approved stockists; no subscription, licensing, or recurring model is in evidence. Sustainability credentials include a wind turbine (since 2011), a 6.4MWp solar farm power purchase agreement with Lightsource BP (since 2018) supplying ~25% of energy needs, 75%+ waste polycarbonate recycling, and 94% post-production waste recycling over the past three years. The company actively pursues regulatory leadership (BBA, Secured by Design, RIBA-accredited CPD seminars) and invests in capacity (record £15m Mallusk expansion announced June 2025) and product development (Pyramid Roof Lantern 2025, Circular Glass 2023, StormCrate55 2020).
