What KAT does

KAT is a family-owned UK manufacturer of bespoke uPVC and aluminium windows and doors, founded in 1998 by David Richards and headquartered in Macclesfield, Cheshire. The company produces bifolding doors (uPVC and aluminium), sliding patio doors (inline and lift-and-slide), entrance doors (Hurricane K64 aluminium/steel, Art Deco heritage, Spitfire S-200 luxury aluminium, composite), French doors, casement windows (Halo, Rustique, Kraftsman flush, Art Deco) and a commercial aluminium range covering shopfronts, curtain walling, facades and automatic doors. Manufacturing uses premium-supplier profiles from VEKA, Halo (Rehau), AluK, Kawneer, Metal Technology, Senior SAS and Smart Aluminium, with proprietary elements including the Hercules roller system for triple-glazed uPVC patio doors, the mechanically jointed Kraftsman flush casement, and the K64 Hurricane door with Renolit Exofol Solar Shield surface treatment achieving Passive House-level U-values.

The company operates three manufacturing facilities in Cheshire, Sussex and Ayrshire, and sells primarily through a network of authorised Trade Partners and Design Partners — independent, mostly family-owned installers — covering the north west of England, the Midlands and north Wales, with a factory trade counter showroom in Macclesfield and a website-based Door Designer configurator supporting both trade and direct homeowner channels. Pricing is not publicly disclosed; revenue is generated through one-time product sales with a 10-year warranty, with no software or recurring element. KAT sits within the privately owned Kaliber Group alongside sister brands Spitfire Doors (premium aluminium entrance doors) and Universal Arches (architectural arches), enabling cross-portfolio distribution. The company explicitly positions itself as a low-volume, high-quality bespoke specialist rather than a mass producer, and is recognised in UK trade sources as the authentic market leader in uPVC patio doors, having won consecutive North West Enterprise Awards for Best Patio Company in 2017 and 2018.

Scale indicators5 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Everest (UK): Long-established UK national manufacturer and installer of windows, doors and home improvements with vertically integrated operations. Overlaps on product category and UK market but competes in volume consumer segments rather than bespoke trade supply.
• Safestyle UK: Volume UK installer of uPVC windows and doors operating a nationwide direct sales force. Compares on window/door product and UK market but addresses value-driven replacement demand rather than KAT's premium trade supply.
• Eurocell: Vertically integrated UK PVC-U profile extruder and window/door fabricator with national trade counter network. Compares to KAT on uPVC window/door product but operates at much larger scale across full fenestration, roofline and conservatory categories.
• Anglian Home Improvements: UK's largest direct-to-consumer home improvement company selling windows, doors, conservatories and roof trim nationwide. Comparable end-product category (windows and doors) but opposite go-to-market (high-volume consumer marketing versus KAT's trade-supply specialist model).
• Reynaers Aluminium: Belgian-headquartered premium aluminium systems supplier (profiles, slabs, curtain wall) with UK fabrication partner network. Comparable to KAT on aluminium product technology but operates as a systems house supplying fabricators rather than as a finished-product brand.

Direct peers

• Origin Global: UK manufacturer of premium aluminium bifold doors, sliding doors and windows with proprietary OW-70 and OB-49 systems. Closely comparable to KAT's aluminium ranges in product, target customer (premium residential) and trade-supply model, with a much larger direct-to-consumer marketing engine.
• Spitfire Doors: Spitfire Doors is the KAT sister company within Kaliber Group, manufacturing premium aluminium entrance doors (S-200 Series) sold via the same trade channels. Directly comparable niche specialist in UK high-end fenestration; overlaps in product category, customer base (trade installers) and group ownership.
• Universal Arches: Universal Arches is a KAT sister company within Kaliber Group, manufacturing curved and arched uPVC/aluminium frames. Directly comparable as a niche specialist fenestration fabricator within the same group, sharing installers and back office.
• Express Bifolds: UK specialist fabricator of aluminium and uPVC bifolding, sliding and entrance doors, primarily serving installers in southern England. Overlaps with KAT's core product mix (bifolds, sliders, front doors), manufacturing-supply model and channel-partner GTM.

Regional players

• CR Smith: Scotland-based bespoke uPVC and aluminium window and door manufacturer with similar trade-supply ethos and family-owned heritage to KAT. Closely comparable manufacturing/operating model but geographically focused on Scotland rather than NW England/Midlands.
