About Voltforge
Voltforge builds campervan electrical systems, wiring looms and connector assemblies for van builders, overlanders, leisure vehicles and 4x4s — the customer-facing side of Zeromachine Ltd, a UK engineering company focused on practical electrical and mechanical systems for real machines. Zeromachine covers the broader engineering work: system architecture, drivetrains and energy concepts, control strategies and small‑batch manufacturing under the Works Studio banner. Voltforge concentrates on the part everyone has to live with day‑to‑day – the wiring looms, electrical systems and cable sets that make your ideas actually work in campervans, caravans, leisure vehicles, van conversions, 4x4s, plant and motorsport.
Founded in November 2024, Zeromachine grew out of a four‑and‑a‑half‑year quest to re‑imagine sustainable construction equipment, bridging cutting‑edge hydrogen fuel cell innovation with the rugged demands of real‑world construction sites and farms, with a common‑sense, lifecycle‑first approach to design. Voltforge is the customer‑facing side of that same team: we take the Zeromachine engineering‑first mindset and apply it to wiring looms, electrical systems and cable sets for campervans, caravans, leisure vehicles, van conversions, 4x4s, plant and motorsport, along with the components that support them.
Who we work with
If you’re building a campervan, van conversion or overlander and you want the electrical side done properly — not just connected until something lights up — Voltforge is built for you. That might mean buying a connector kit from the shop, downloading a reference guide, or having a conversation about your system design before you spend money on components. All three are valid starting points.
If your leisure vehicle, campervan or 4×4 has developed an electrical fault you can’t trace, or an installation that’s grown into a mess over time, the repair and diagnostic service is where we start. We find the fault, fix it properly and leave you with a system that makes sense — documented, traceable and easier to work on next time.
If you’re a small converter, van builder or specialist workshop who needs wiring expertise without a full-time electrical engineer on the payroll, we can act as your wiring partner. System design, harness supply, component sourcing and the kind of ongoing technical support that means you’re not reinventing the loom on every build.
How we work
The shop is the starting point for most people — connector kits, pigtail assemblies and electrical components that arrive ready to use, with the engineering thinking already done. If the job needs more than an off-the-shelf part, the conversation is always open.
We supply and install quality power electronics, battery systems and charging equipment from trusted manufacturers — so if your build needs a complete electrical solution rather than just components, we can take that on too.
For bespoke work — system design, custom harnesses, documentation, trade supply — tell us what you’re building and where you’re stuck. We’ll give you an honest picture of what’s involved before any chargeable work begins.
Behind the scenes
Zeromachine and Voltforge are led by founder and lead engineer Gavin Duffy, supported by a small but growing team of engineers, advisors and industry partners. Gavin is a Scottish automotive electrical design engineer with over 30 years of experience, including time as Chief Electrical Engineer at a major leisure vehicle OEM, and today his work spans both modern campervan and leisure‑vehicle electrics and low‑ and zero‑emission technologies in passenger‑carrying vehicles, off‑highway equipment and non‑road mobile machinery.
That mix of hands‑on harness and systems experience, clean‑technology R&D and real‑world production work is the backbone of our engineering – from Zeromachine’s larger system‑level projects through to the wiring looms, electrical systems and cable sets we deliver through Voltforge. That same mindset underpins the kind of environmentally aware and socially responsible company we want Zeromachine to be as we work towards establishing a world‑class R&D and manufacturing facility in Blyth.
Gavin remains a petrolhead at heart, with early roots in stage rallying and off‑road motorsport as both a competitor and an official. That mix of motorsport pragmatism and clean‑technology focus is why the wiring and systems we build through Voltforge aren’t just tidy on paper – they’re designed to be rewarding to use, straightforward to fit and easier to keep running and fault‑find in the real world.
