Precision Components. Built to Your Specification.

Five product categories. One standard: British precision. Whether you need a production run or a prototype, we build to your drawings, your tolerances, and your sector’s requirements.
March26 automotive wire harness UK

Automotive Wire Harnesses

For OEMs, Tier-1 suppliers, and specialist vehicle builders.
From dashboard looms to chassis harnesses, we manufacture automotive wire harnesses to USCAR and LV-214 standards. Each harness is built to your schematic, assembled by trained technicians, and tested to 100% continuity before dispatch. We work with both traditional and EV platform

Applications:

defence wire harness manufacturer

Aerospace & Industrial Harnesses

Built to the precision demands of flight-critical and defence applications.

Aerospace harness assembly is not a commodity. It requires certified processes, documented traceability, and zero tolerance for failure. March26 is actively building towards AS9100D accreditation, with processes aligned to IPC-A-620 Class 3 standards. Our aerospace harnesses are suited for UAVs, fixed-wing platforms, ground defence systems, and industrial control applications where reliability is non-negotiable.

Applications:

EV wire harness UK

Battery Interconnectors & EV Components

Connecting the UK's battery manufacturing ambitions to a reliable domestic supply chain.
As UK Gigafactories scale up — AESC Sunderland, Envision, Agratas — the demand for precision battery interconnectors is accelerating. March26 manufactures cell-to-cell busbars, HV cable assemblies, and battery pack connectors to the exacting tolerances required by modern battery systems. High conductivity. Thermal resilience. Built for the demands of next-generation energy storage.

Applications:

flexible busbar UK

Copper Busbars, Lugs & Terminals

High-conductivity copper components for power distribution and switchgear applications.
March26 supplies a full range of copper busbars, lugs, and terminal components for industrial, energy, and automotive power distribution. Available in rigid and flexible formats, with nickel, silver, or tin plating options to suit your application. All components are manufactured to IEC standards and supplied with full material certification.

Applications:

medical wire harness manufacturer

Medical & Specialist Cable Assemblies

For life-critical devices where failure is not an option.
Medical cable assemblies demand a different level of care. March26 manufactures to medical-grade material specifications, with full component traceability, clean build environments, and documentation that satisfies regulatory audit requirements. From diagnostic imaging cables to implantable device looms, we understand that the components we build form part of a system that someone depends on.
