Engineering reliable power systems for mobile freedom

Who We Are

We started in 2018 after spending years traveling across Europe in converted vans. The frustration of unreliable power systems and poorly installed electrical setups drove us to establish a company focused entirely on doing this work properly.

Every member of our team has lived in a campervan. We understand the difference between a system that looks good on paper and one that actually works when you're parked in a remote valley for two weeks. That firsthand experience shapes everything we install.

Our workshop is based in Bristol, where we've completed over 300 installations for travelers heading everywhere from Scottish highlands to Moroccan deserts. Each project is unique because no two travel styles are identical.

What Drives Our Work

No Shortcuts

We use marine-grade wiring, proper cable sizing, and oversized fusing. Installations are permanent solutions, not temporary fixes. Every connection is crimped, soldered, and heat-shrunk.

Real-World Testing

Systems are load-tested before handover. We simulate actual usage scenarios including high-draw appliances, low-light charging conditions, and temperature extremes.

Honest Advice

If your planned system is oversized or includes unnecessary components, we'll tell you. Our goal is right-sized solutions, not inflated invoices.

Ongoing Support

Questions don't stop after installation. We provide phone support for troubleshooting, system optimization advice, and guidance on future expansions.

Team collaboration on electrical design

Technical Expertise

Our lead installer holds City & Guilds Level 3 qualifications in electrical installation. All team members are trained in low-voltage DC systems and high-current battery management.

We stay current with rapidly evolving battery technology, monitoring equipment, and integration protocols. Lithium battery systems require different handling than traditional AGM setups, and many installers haven't adapted their practices.

We're also familiar with the specific challenges of different vehicle types. Panel vans have different roof structures than coachbuilt motorhomes. Older vehicles need retrofitting approaches that newer builds don't require.

Our Approach to System Design

Most companies start with a standard package and modify slightly. We start with your actual requirements and build from there.

During consultation, we ask about refrigerator type, heating method, laptop usage hours, whether you cook electrically, and how often you drive. These details determine whether you need 200Ah or 600Ah of battery capacity, whether a 400W solar array is sufficient or if you need 800W.

We also consider your travel style. Someone who moves daily and drives several hours will have different charging patterns than someone who parks for weeks at a time. Winter travelers in northern regions need more battery capacity than summer-only users in Mediterranean climates.

The result is a system sized appropriately for how you actually live, not based on arbitrary package tiers.

Built to Last

Campervan electrical systems endure constant vibration, temperature fluctuations, and the occasional unexpected jolt. Components must be secured properly and wiring must have appropriate strain relief.

We've seen too many installations where batteries weren't adequately fastened, inverters were mounted in poorly ventilated spaces, or solar cables were routed through sharp metal edges without grommets.

Our installations are designed for durability. Five years down the road, connections should still be solid and components should still be functioning as intended. That's the standard we build to.
