We Build Energy Projects We’re Proud Of

Armex Energy is a UK-based energy company delivering battery storage, commercial solar PV, and maritime electrification projects. We’re a small, agile team with a clear purpose: to build practical energy systems that reduce emissions, perform reliably, and genuinely make a difference.

We believe the energy transition should be delivered with care, competence, and honesty, not over-promised or rushed.

Our Founders

Armex Energy was founded by James Costello and Ash Cairney with a shared belief that energy infrastructure could, and should, be delivered better.

What We Do

We design, build, and support energy infrastructure that helps organisations generate, store, and use electricity more sustainably.
Battery Energy Storage
We deliver grid-scale and commercial battery storage projects that improve flexibility, resilience, and long-term performance of the energy system.
Commercial Solar PV
We design and install high-quality solar PV systems for commercial and industrial sites, focused on reliability, safety, and real-world output.
Port Electrification
We support ports and operators with electrification and shore power infrastructure that reduces emissions, noise, and fuel use at berth.
EPC Project Delivery
From early feasibility through to commissioning, we take responsibility for coordinating design, procurement, construction, through to handover.
Operation & Maintenance
We provide ongoing maintenance, monitoring, and optimisation to protect asset performance, reduce downtime, and extend system life.
Responsible Delivery
We work carefully and transparently, prioritising safety, collaboration, and long-term impact over shortcuts or over-promising.

Our Team

In addition to our specialist supply chain, Armex is supported by a core, trusted team who share the same values of care, responsibility, and practical problem-solving.

Christina Costello
Christina looks after administration and bookkeeping, helping keep the business organised, compliant, and running smoothly behind the scenes.

How We Work

We believe good energy projects are built on trust, clarity, and collaboration.

Being an agile team allows us to stay closely involved at every stage, from early feasibility and design through to construction, commissioning, and long-term support. We work openly with clients, partners, and stakeholders, and we’re not afraid to have honest conversations when trade-offs or challenges arise.

We prioritise safe working, realistic programmes, and solutions that make sense in the real world, not just on paper.

Our Approach to Sustainability

For us, sustainability isn’t a marketing statement, it’s the reason we exist.

By delivering battery storage, solar PV, and electrification projects properly, we help reduce reliance on fossil fuels, improve air quality, and support a more resilient energy system. Just as importantly, we try to do this responsibly: considering whole-life performance, minimising waste, and choosing long-term value over short-term gain.

We know we’re not perfect, but we’re committed to learning, improving, and doing better with every project we deliver.
