What System Design Evaluation does
System Design Evaluation Ltd (SDE) is a UK-based independent technology company founded in 1985 that provides impartial assessment, design, development, and safety management services for defence platforms, munitions, and weapon systems across land, sea, and air domains. Its core service lines cover Land Safety & Environmental Management, Air Weapons Safety, Naval Safety & Environmental Management, Defence Systems, Commercial Defence Systems, Renewables & Autonomous Power Systems, Environmental Consultancy, Counter Explosives Ordnance, and Electromagnetic Environmental Effects (E3) Services.

Its proprietary risk-management tool, SDE MERIT®, is a registered trademark, and operations are governed by an ISO 9001:2015-certified Integrated Management System.
SDE's business model is professional-services consulting delivered on a quote-based, multi-year contract basis directly to the UK Ministry of Defence, NATO, and global defence prime contractors. Pricing is not publicly disclosed and engagement is conducted through direct enterprise sales rather than through channel partners. The firm operates two UK offices (Ware headquarters and a registered office in Towcester), holds an Armed Forces Covenant Silver Award (2025), and maintains a curated professional network — SDE Nexus — connecting defence and security talent with organisations. In April 2026 SDE became part of EKA Group Holdings Limited alongside EKA Limited, combining independent safety assurance with engineering delivery in military vehicle recovery systems, special-to-role equipment, and chassis integration.
