Aico

What Aico does

Aico is a UK-based manufacturer of residential fire and carbon monoxide alarms, operating as a wholly-owned subsidiary of Ei Company and self-described as the European market leader in home life safety. Founded in 1990 by Ken Ainsworth, the company designs and manufactures its alarm range in Ireland and distributes from its Oswestry, Shropshire headquarters, which includes a Centre of Excellence for training opened in 2015 and expanded in 2019.

The product portfolio spans five core alarm series (3000, 1000, 600, 200, 140e) covering mains-powered and battery-powered smoke, heat, CO, and multi-sensor variants, supported by proprietary wireless interconnection technologies (RadioLINK, RadioLINK+, SmartLINK) and acoustic data extraction (AudioLINK+). Through the 2020 acquisition of HomeLINK, Aico extended into a connected home IoT platform comprising the Ei1000G Gateway, Ei1020/Ei1025 environmental sensors (temperature, humidity, CO2, damp/mould risk), Case Management software, a Resident App, and a Portal for remote portfolio monitoring by social housing providers.

Aico sells exclusively through a UK network of authorized electrical distributors and certified installers, supported by 32 Relationship Managers providing regional coverage, an Expert Installer training scheme, and City & Guilds Assured courses. The primary customer segments are UK social housing providers, electrical contractors, and electrical distributors, with secondary exposure to private landlords and homeowners. Revenue is generated from hardware sales (alarms, sensors, accessories), recurring subscription/IoT platform fees (HomeLINK), and professional training services. The company is privately held, with no disclosed funding rounds and no public revenue figures.

Direct peers

• FireAngel Safety Technology: UK-based manufacturer of smoke, heat, and carbon monoxide alarms with a connected/smart product line (Wi-Safe 2). Directly comparable to Aico as a domestic fire/CO alarm specialist competing for the same UK social housing, contractor, and distributor channels.
• Kidde: One of the world's largest manufacturers of residential smoke and carbon monoxide alarms (now part of Carrier Global). Comparable to Aico as a direct rival in domestic fire/CO detection hardware, with broader geographic reach and overlapping product categories including smart/connected variants.
• BRK Brands / First Alert: Major US-headquartered manufacturer of residential smoke, CO, and combination alarms under the First Alert and BRK brands. Directly comparable product set (smoke/CO alarms with interconnect and smart variants) and overlapping retail/wholesale distribution model.
• Google Nest (Nest Protect): Google's smart smoke and CO alarm, positioned as a premium connected home safety product. Comparable to Aico's 3000 Series and HomeLINK as a smart, app-connected residential alarm, though distributed through consumer channels rather than trade distributors.
• Ei Electronics: Irish-based manufacturer of residential fire and CO detection products and the likely operating parent group behind Aico's parent (Ei Company). Closely comparable product range, manufacturing footprint (Ireland), and channel structure to Aico.

Broad incumbents

• Resideo (Honeywell Home): Spun off from Honeywell, Resideo offers a broad portfolio of home safety, security, and comfort products including smoke/CO alarms and connected home platforms. Comparable to Aico at the connected-home safety layer but operates at much larger scale across multiple product categories.
• Legrand: Global specialist in electrical and digital building infrastructure with growing exposure to connected home safety and environmental sensing via Netatmo and its wiring device portfolio. Comparable to Aico in adjacent smart-home safety/sensing categories but at vastly larger scale.

Emerging players

• Netatmo (Legrand): French smart home company (owned by Legrand) offering connected smoke alarms and indoor air quality sensors (Healthy Home Coach). Comparable to Aico's HomeLINK environmental sensors and smart alarm range, with stronger consumer-brand reach in continental Europe.
• Cavius Aps: Danish designer and manufacturer of premium residential smoke, heat, and CO alarms with wireless interconnection. Comparable to Aico as a specialist in compact, design-led home life safety alarms competing in European retail and trade channels.

Regional players

• Hekatron Technik: German specialist in smoke alarm systems, voice alarm systems, and fire detection, holding VdS certifications. Comparable to Aico as a specialist residential/commercial fire detection manufacturer, but primarily serving the DACH region rather than the UK social housing market.
