What Rockfort Engineering does

Rockfort Engineering Limited is a privately held UK engineering consultancy, founded in 2013 by Angus Lyon and headquartered in Banbury, Oxfordshire (registered in Scotland as company SC460884). The firm specialises in the design, development, and integration of safety-critical electronic and software systems for road, motorsport, HGV, marine and aviation applications, with ISO 26262 functional safety positioned as its core engineering philosophy. Its technical offering spans embedded real-time control software, bespoke and off-the-shelf electronic control units (ECUs), high-voltage battery systems, 12V and 48V battery modules, low-voltage and high-voltage power distribution units (PDM/PDU), and full powertrain and braking systems, underpinned by simulation, modelling and vehicle-level efficiency optimisation.

The company serves automotive OEMs, Tier 1 suppliers, motorsport teams (Formula 1, Formula E, WRC, WEC) and electric-vehicle developers, with visible reference customers including Mahindra Racing and Ariel (E-Nomad). Its go-to-market is sales-led and bespoke, with services quoted per project under milestone-based net-30 terms in GBP; the company also sells its "REL" hardware product line and grants buyers a perpetual royalty-free licence to subsisting IP. The firm operates with a sub-10-person engineering and administration team led by its founder, and holds no external investors, parent company, or disclosed funding rounds.

Core offering

Rockfort Engineering is an engineering consultancy that designs, develops and integrates automotive and vehicle systems, specialising in electric powertrain technology and safety-critical electronics. It delivers a portfolio of REL-branded hardware products — high voltage battery systems, 12V/48V battery modules, low- and high-voltage power distribution units, and bespoke ECUs — alongside embedded real-time control software and full systems engineering services covering EV powertrain design, ISO 26262 functional safety, mechanical/electronic design, vehicle test and development, and motorsport track support across F1, Formula E, WRC and WEC.

Product overview

Rockfort Engineering Limited is a single engineering services business rather than a multi-product SaaS platform; however, around its core safety-critical engineering philosophy it sells a named portfolio of physical products and engineering service modules. The physical product line (branded "REL" and shown on the Products page) comprises REL High Voltage Battery Systems, REL 12V and 48V Battery Modules, REL Low Voltage Power Distribution Units (PDM/PDU) with optional integrated battery, REL High Voltage Power Distribution Systems (HV PDM) and REL Electronic Control Units (ECU). These products underpin and are delivered through four interlocking service practices: Electric Vehicles (powertrain design, vehicle efficiency optimisation, EV battery systems, HV control and distribution, ancillaries such as brake-by-wire / cooling / DCDC, and vehicle test and development), Systems Engineering (Functional Safety to ISO 26262, Embedded Control Software, Electronic Design, Mechanical Design, and Corporate Technology & Project Management), and Motorsport (Track Support, Design and Build, and Technical Partnerships across F1, Formula E, WRC, WEC and other series). Together, the REL hardware modules integrate with Rockfort's bespoke control software and safety engineering services to provide complete safety-critical electronic and powertrain systems for road, race, HGV, marine and aviation applications.
