What FDB does

FDB is a UK-based specialist manufacturer of industrial and defence-grade electrical protection equipment, operating continuously for more than 50 years. Its product range centers on residual current devices (RCDs), residual current breakers with overcurrent protection (RCBOs), earth continuity monitors, RCD test sets, fully adjustable multi-function RCDs, variable earth leakage relays, percentage earth fault relays, and external toroidal current transformers up to 240mm in diameter. Devices are offered both as standalone panel-mounting components and as pre-assembled enclosed units in steel, stainless steel, or GRP housings fitted with socket outlets or terminals, and the firm designs and builds bespoke custom panels in-house for non-standard applications.

The company sells primarily through direct B2B engagement to industrial customers and to UK Defence forces and support industries, where its bespoke engineering capability and certified quality systems are the principal purchase drivers. Pricing is privately negotiated on a quote basis with no published price list, consistent with custom industrial B2B procurement. The operating footprint comprises headquarters in Isleworth, Middlesex and a registered corporate address in Wellingborough, Northamptonshire; headcount is reported in the 251-500 range. The firm holds ISO 9001:2015 certification covering the manufacture of electrical protection and safety equipment, providing a recurring independent validation of its quality management system.

Revenue is not publicly disclosed; commercial scale is implied by the 251-500 headcount range, multi-decade continuity, and qualifying-supplier status with UK defence procurement. Customer reliance on specification compliance, certification, and bespoke engineering creates moderate switching friction, while the niche product category limits direct volume comparability to broader electrical equipment OEMs.
