What Brewer Cowls does

Brewer Cowls (legally Brewer Metalcraft Limited) is a UK-based manufacturer of chimney cowls, birdguards, chimney caps, terminals, and related flue products, founded in 1970 and operating from a West Sussex factory in Chichester. The company produces an extensive catalogue of anti-downdraught cowls (Aerodyne, UFO, Aspirotor, FlueCube, Windmaster, Stealth, H Cowl, Lobster Back, Bonnet), birdguards for gas and solid fuel systems, chimney cappers, liner terminals, and twin-wall components, in materials including aluminium, stainless steel, and galvanised steel, with terracotta, buff, black, and natural finishes. In addition to in-house manufactured products, Brewer Cowls distributes third-party European brands — notably the Poujoulat Aspirotor and Exodraft motorised chimney fans — giving the catalogue coverage from passive cowls (£8.50–£323) up to mechanical fans at £1,000+.

The company generates revenue through three streams: direct-to-consumer e-commerce sales via its website, a dedicated trade account programme offering quantity discounts to chimney sweeps, roofers, and fireplace installers, and a bespoke custom-manufacturing service for non-standard chimney configurations delivered in approximately 10 working days. Free technical support and a 3-step product finder tool assist customer selection. Distribution is UK-only (Northern Ireland is excluded due to customs/regulatory reasons), with next-day delivery available on in-stock items. The company is privately held with no disclosed institutional investors, operates with 11–50 employees, and is registered in England and Wales.
