Its products span wiring accessories, cable management, fire detection and safety alarms, residential and commercial lighting, security and emergency lighting, EV charging, PV solar controllers, circuit protection, smart controls, site electrics, controls, power distribution, and portable power.

Revenue is generated primarily through hardware sales distributed via national and regional electrical wholesalers (the principal channel), with additional distribution through DIY retailers, direct specification relationships with major UK housebuilders, dedicated channels for the Republic of Ireland market, and an export sales channel for international markets. The Detanet B2B online ordering platform facilitates transactions with wholesale partners. Pricing is wholesale- and contractor-account-based and is not publicly disclosed; the company reports UK turnover in excess of £90 million. The group holds ISO 9001 (quality), ISO 14001:2015 (environmental), WEEELink, and BSI memberships, and operates with a privately held structure with no disclosed parent company, private equity sponsor, or external venture funding.

Recent strategic activity is centered on portfolio expansion through the Timeguard acquisition (2023), the Deta.e sustainability brand launch (2023), and a sustained product launch cadence through 2025-2026 that includes entry into PV solar controls (PV1000 Boostmaster), comprehensive circuit protection compliant with the 18th Edition IET Wiring Regulations, smart Bluetooth-mesh dimmers, coastal-rated LED floodlights, and first-to-market frameless 4-in-1 PIR bulkheads, alongside a redesigned corporate website (April 2025).
