Gap

What Gap does

GAP (General All-Purpose Plastics Limited) is a UK-based manufacturer and distributor of low-maintenance PVC-U building products, founded in 1993 and headquartered in Blackburn, Lancashire. The company operates 4 manufacturing sites and a national depot network of 113+ locations across the UK, complemented by an online trade ordering platform with UK-wide delivery and local depot collection. Its core product portfolio spans roofline products (uPVC fascias, soffits, cladding), rainwater systems (gutters and downpipes), windows, GRP doors manufactured at the Knowsley facility, aluminium bi-folds and sliders, sealants, and underground drainage systems distributed from partner brands such as Soudal and FloPlast. Wholly-owned subsidiaries include Rockdoor (the proprietary composite door brand marketed as the UK's most secure and thermally efficient residential door) and Homeline Building Products.

The business model is sales-led and built around a trade account and depot network GTM. GAP sells to three principal customer segments: SMB local window and door installers, mid-market regional house builders, and enterprise-scale national house builders (e.g., Taylor Wimpey, with whom GAP received an Outstanding Contribution Award in May 2026). Refurbishment contractors form a secondary segment. Revenue is generated through one-time product sales at trade-account pricing, with customers ordering online or directly at depots; pricing is opaque publicly and is only revealed after trade account registration. FY2025 turnover was £157.6 million.

GAP is privately held and founder-led by Charles Greensmith, with no external institutional investment or public listing. The company employs over 1,000 people and has remained focused on the UK domestic market. Recent strategic activity centers on organic depot expansion (new Chelmsford and Gloucester depots in 2026), deepened enterprise customer relationships, and continued certification accumulation (CE, BFRC, Secured by Design, Made in Britain). The company is operationally mature with multi-decade tenure at established depots such as Liverpool (April 1996 opening).

Expansion highlights4 records

Broad incumbents

• Huws Gray: Large UK builders' merchant and building products distributor with an extensive branch network. Comparable trade-channel distribution model to GAP's depot network, but broader product offering including heavyside materials.
• Travis Perkins: UK's largest builders' merchant operating hundreds of branches across general building materials. Wider product portfolio than GAP, but overlaps as a trade-channel building products supplier to the same installer and housebuilder customers.
• Jewson (Saint-Gobain): UK builders' merchant division of Saint-Gobain with national branch coverage. Competes with GAP's depot model for trade customers, though with a broader general-building-materials mix rather than PVC-U specialism.
• Saint-Gobain UK & Ireland: UK arm of global building products group, with fenestration and building envelope offerings (including Jewson merchants). Much larger and more diversified than GAP, but operates in overlapping categories and channels.

Direct peers

• Eurocell: UK manufacturer and distributor of PVC-U building products (windows, doors, roofline, rainwater) operating a national trade branch network. Most directly comparable to GAP on product mix and depot-led distribution model.
• Crystal Direct: UK manufacturer of PVC-U windows, doors and conservatories with a direct trade supply model. Overlaps with GAP's window and door manufacturing footprint, particularly in fabrication of finished fenestration products.
• Profile 22 (Epwin Group): UK-based PVC-U window and door profile systems manufacturer within Epwin Group. Overlaps directly with GAP's PVC-U manufacturing offering for the fenestration supply chain.
• Deeplas (Cornerstone Building Brands): Manufacturer and supplier of PVC-U roofline products (fascias, soffits, cladding) and rainwater systems — directly overlapping with GAP's core roofline and guttering manufacturing range.
• Synseal / K2 Aluminium Systems: Manufacturer of PVC-U and aluminium profile systems for windows, doors and conservatories, supplying fabricators across the UK. Compares to GAP on PVC-U system manufacturing serving the same fabricator/installer base.

Others

• FloPlast: UK manufacturer of PVC rainwater and underground drainage systems. FloPlast is actually a supplier to GAP (its drainage range is distributed through GAP depots), making it a partner/adjacent peer within the same PVC-U building-products ecosystem.
