The problem

Is your van's electrical system holding you back?

If you bought your campervan more than a few years ago, chances are the electrical system is outdated. Technology has moved on — and so can you.

Tired lead-acid batteries

Your original leisure battery is probably 3-5 years old. It's losing capacity, taking longer to charge, and leaving you without power when you need it most.

Limited off-grid time

You can only stay off-grid for a night or two before needing to find a campsite or drive for hours. Your adventures are dictated by your battery, not your plans.

Unreliable power

You're never quite sure how much power you have left. The fridge cuts out, devices won't charge, and you're constantly worrying about running flat.

Benefits

Why upgrade your electrical system?

Modern power systems transform your camping experience. Here's what you'll gain.

Extended off-grid time

Stay off-grid for days, not hours. Lithium batteries hold more usable power and charge faster than lead-acid.

Free solar power

Harvest energy from the sun while you explore. Solar keeps your batteries topped up without running the engine.

Fast installation

Most upgrades completed in 1-3 days. No waiting months like full conversion companies.

12-month warranty

All installations come with a 12-month workmanship warranty. Plus manufacturer warranties on components.

Professional grade

We use Victron, Renogy, and other professional-grade components trusted by the industry.

Local service

Based in West Somerset with a 50-mile service radius. Personal service, not a faceless company.

How it works

A clear five-step upgrade

From first contact to an upgraded van in as little as two weeks.

02

Detailed quote

Receive a clear, itemised quote within 48 hours, including an estimated time to get parts. No hidden fees, no surprises.

Professional fitting

We install your new system in 1-3 days at our workshop. For some projects we may need to come to you. Full demonstration and handover included.
