Voltforge provides campervan electrical repair, wiring and system design services across North East England and the Scottish Borders. If you’re converting your own vehicle, running a small conversion business or trying to sort out electrics that aren’t behaving, Voltforge brings the specialist system design and harness expertise that complements your skills and experience.

From diagnosing and repairing existing systems to designing and building new wiring and electrical setups, we focus on solutions that are reliable, easy to understand and straightforward to maintain, modify and troubleshoot over time – the same engineering‑first mindset that runs through our work at Zeromachine.

Wiring & Electrical Services we offer

We cover a wide range of wiring and electrical work, but these are the main services customers ask us for most often.

System Design & Planning

Get a safe, practical electrical design for your campervan, motorhome, caravan or 4×4, including battery setup, charging, protection and cable sizes, so you can build with confidence instead of guesswork.

Custom looms and harness builds

We design and build labelled looms and harnesses for new conversions and upgrades, ready to install and easy to work on later – from single circuits to full vehicle looms.

Diagnostics, repairs and upgrades

If your existing electrics aren’t behaving, we track down faults, fix underlying issues and recommend sensible upgrades, tidy‑ups or re‑works to improve reliability and safety.

Support for small converters and trade

For small workshops and specialist builders, we provide the wiring expertise you don’t have in‑house – from system design and documentation to repeatable harness supply for your own builds.

Building your own camper or overlander and want the electrics to match the rest of the build? We can help you design a safe, practical system and supply wiring that’s actually buildable.

  • Sense & Sanity check of your ideas and sketches
  • Full system design with cable sizes and protection
  • Custom looms built and labelled for your layout
  • Support during install if you get stuck

Factory and older leisure vehicles often have tired, overloaded or hacked‑about wiring. We help you sort problems and plan sensible upgrades rather than just bolting on more gear.

  • Fault‑finding and safety checks on 12 V and 230 V leisure systems
  • Replacement and rationalisation of old wiring
  • Battery, charging and protection upgrades
  • Advice on adding solar, inverters and extra loads

Motorsport wiring needs to be reliable, fixable in the paddock or service area and easy to understand under pressure – not just lightweight and flashy. Voltforge applies competition‑grade thinking to looms and systems for rally, race and cross country vehicles.

  • Custom looms for race, rally and track cars
  • Harness tidy‑ups and improvements on existing cars
  • Integration of data loggers, pumps, fans and ancillaries
  • Clear labelling and documentation to speed fault‑finding between runs

If you build vans or 4x4s for customers, Voltforge gives you wiring and electrical expertise without needing a full‑time electrical engineer on staff.

  • System design and documentation for your standard builds
  • Repeatable harness designs and loom supply
  • Help cleaning up legacy wiring on customer vehicles
  • A knowledgeable point of contact for tricky jobs

For plant and agricultural machinery, wiring lives in a harsh environment and has to earn its keep every day. We help engineers and workshops diagnose electrical issues and persistent gremlins, improve existing systems and design better wiring for new projects and retrofits.

  • Electrical system diagnostics and re‑wiring on mobile plant and implements
  • Designing and documenting control looms and add‑on systems
  • Upgrades to connectors, routing and protection for durability
  • Ongoing support for repeat builds and field fixes

Alongside custom work, we’re building a range of standardised looms and component bundles for popular layouts so you can buy proven solutions off the shelf.

  • Pre‑engineered looms for common camper layouts
  • Matched component kits for specific use‑cases
  • Pre-terminated cable sets & pigtails for you to install in your loom
  • Clear documentation and labelling included
  • Online shop launching soon – ask if you’d like to be first in line

Built on Real‑World Experience

The work you see here comes from real vans, overlanders, rally cars and factory builds – not generic shots. The same people who design and build these looms, cable sets and installs are the ones you’ll be dealing with, so the wiring solutions we offer are shaped by what actually survives hard use on the road, on stages and on site.

Whether it’s a new system, an upgrade or a thorny wiring problem, we’ll help you find a practical, sustainable way forward.

Frequently Asked Questions (FAQs)

Do you only work on brand‑new conversions?

No. We’re just as happy diagnosing, repairing and improving existing electrics as we are designing brand‑new systems. That includes factory motorhomes and caravans, older conversions, previous DIY work, overlanders, 4x4s, motorsport vehicles and selected plant and agricultural machinery. We’re not general auto‑electricians – we specialise in leisure, off‑road and specialist vehicle electrical systems, where good design, documentation and the right components matter just as much as getting the lights back on.

There are plenty of competent, reliable auto‑electricians who are well equipped for day‑to‑day vehicle diagnostics and dealer‑level fault‑finding; our role is to complement that by focusing on the design, wiring and system side of leisure, off‑road and specialist electrics.

 I’m doing my own install – will you still work with me?

Yes. We regularly support DIY builders with design, checking their plans, specifying components and supplying looms, then answering questions during the install if needed. If we spot anything that isn’t safe or really needs to be condemned and re‑done, we’ll say so clearly but constructively – safety always comes first, and sometimes the safest option is to accept that a previous DIY attempt needs to be stripped out and started again with a better plan.

Do I have to use a specific brand of equipment?

No. We’re brand‑agnostic and will normally work with reputable gear you already have or recommend suitable parts for your budget and use case, whether that’s Victron or other established manufacturers. We’re very cautious about ultra‑cheap kit from marketplaces like Temu, Amazon and eBay – some items are fine, but a lot of it is poorly made or not properly certified. For safety and reliability, we only work with trusted brands and components that meet the relevant standards, and we may recommend replacing questionable parts before we do any work.

If you’re going to sleep in a campervan, motorhome, caravan or overlander, the electrics need to be treated with the same seriousness as a domestic installation and built to recognised standards – for example BS EN 1648 for 12 V systems in leisure vehicles, BS 7671 (IET Wiring Regulations) for 230 V installations, and the relevant manufacturer and product standards for the equipment used. As OEM‑experienced engineers, we’re very used to spotting cloned or sub‑standard connectors and components, and we’ll flag anything that doesn’t look right before it’s trusted in a vehicle you sleep or travel in. We only work with trusted, properly certified components and will always steer you towards solutions that meet these standards rather than the cheapest options, because cutting corners on electrics can compromise your own health and wellbeing.

Can you work remotely, or do you have to see the vehicle?

We do both, but we’re a mobile service based in south‑east Northumberland and we don’t have workshop facilities at our own premises yet. Design and planning can be handled remotely with good photos, measurements and test results; hands‑on diagnostics and install work are normally carried out on your vehicle across North East England and the Scottish Borders.
If you’re outside North East England or the Scottish Borders, there will usually be reputable local specialists who can handle on‑site work in your area, and we’re happy to support you with design, documentation or advice that they can work from.

Do you work with trade customers and small converters?

Yes. We can act as your wiring and electrics partner – from system design and documentation through to repeatable harness supply for your own builds – whether you’re converting campervans and 4x4s, building overlanders and expedition vehicles, or working on specialist plant and agricultural machinery. We help trade customers and converters standardise their electrics, improve reliability and build‑ability, and get consistent, documented wiring across multiple vehicles instead of reinventing the loom every time.

How do I get started and what will it cost?

Start by telling us what you’re working on, what’s already fitted (if anything), what the problem is and what you want the electrics to achieve. You can share drawings, sketches, photos or an existing loom – whatever you have. We’ll outline whether the answer is likely to be a proven, off‑the‑shelf solution (such as a standard loom, terminated pigtails, cable sets or a component bundle) or whether it needs bespoke work such as system design, custom harnesses and documentation. We’ll also give you an indication of options and likely costs before any chargeable work begins, so you can decide how far you want to go.
