Coughtrie

What Coughtrie does

Coughtrie International Ltd is a privately held British lighting manufacturer founded in 1939 and headquartered at 69-71 Montrose Avenue, Hillington, Glasgow. The company designs and produces die-cast aluminium LED luminaires, emergency lighting systems, lighting controls, and LED retrofit kits engineered for arduous environments. Its product portfolio centres on vandal-resistant bulkhead fittings (CPS, SFB, Ultralux, Cirlux, Azilux, BH&BD, CBC, CPS 2 Small) carrying IK10++ impact resistance and IP65 weatherproof ratings, alongside heritage pendants (SP, SW-10, PW-15) manufactured from tooling first laid down in the 1950s. The company sources over 90% of components from suppliers within a 25-mile radius, supporting a low-carbon supply chain and rapid order-to-despatch timeframes.

Coughtrie operates a direct sales model combining bespoke B2B project specification for housing associations, local authorities, Network Rail, London Underground, and other named enterprise accounts with a publicly priced e-commerce storefront for spares and heritage fittings. Specified accreditations include Section 12 for UK rail tunnel applications, NOMS approval for custodial settings, BS 5266-1:2011 for emergency lighting, ISO 9001 for quality management, and 1000hr salt spray approval for marine use. Revenue is generated through one-time hardware purchases spanning complete luminaires, LED retrofit upgrade kits, and replacement diffusers and components.

In June 2023 the company launched J&G Coughtrie as a heritage sub-brand targeting marine, hospitality, and residential segments, with the SY-6 Compact Oval Bulkhead as its flagship product. Recent product launches include the CBC bulkhead for harsh environments (November 2025) and an expanded LED retrofit kit offering (October 2025). Notable customers include Bletchley Park, Daldowie Crematorium, Mears, Aggreko, Network Rail, London Underground, and London Dockland Light Railway. The company has 11-50 employees and operates exclusively in the UK market.

Product overview

Coughtrie is a British lighting manufacturer (Glasgow, established 1939) offering industrial and heritage luminaires as a unified product portfolio. The core offering centers on robust bulkhead lights (CPS, SFB, Ultralux, Azilux, Cirlux, BH&BD, CBC) designed for social housing, custodial, rail, infrastructure, and heritage applications. These share common features: die-cast aluminium construction, IK10++ impact resistance, IP65 weatherproofing, LED and emergency options, and sensing capabilities. Heritage products (SP from the 1950s, SW-10, PW-15 pendants) form a distinct line for traditional settings. The 2023-launched J&G Coughtrie sub-brand extends heritage aesthetics (SY-6 Compact Oval Bulkhead) to modern marine, hospitality, and residential markets. Services include LED retrofit kits (upgrading existing fittings while retaining bases), emergency lighting systems, and bespoke restoration. All products emphasise durability, with 50-year+ service life and local supply chain (90%+ components within 25 miles) supporting sustainability messaging.
