Describe the fault
When does it happen: driving, parked, charging or using an appliance?
Show the equipment
Photograph the batteries, charger, inverter and fuse distribution.
Include the details
Vehicle, postcode, model labels, error codes and any wiring diagram.
Repair or upgrade?
Can you assess a customer-built conversion?
Yes. Send equipment details and any wiring diagrams. We agree the inspection scope, explain the findings and quote repairs before proceeding. Initial fault finding does not include full installation certification.
Can you improve the existing wiring?
Ask about isolation, fused distribution, cable routing, monitoring and charging upgrades. Mains hook-up or other specialist work is scoped separately, including any specialist inspection required.
Need more power or a heater?
Explore battery and inverter installations or diesel heater fitting. We can quote a combined project or agree the work in stages.
Installation assessments & payment
Free initial WhatsApp photo assessment. An in-person assessment is £100, credited against an installation booked within 30 days. Once the specification and price are agreed, the deposit is £100 for labour-only fitting or 30% for supply and fit. Balance after installation and testing. Dates are confirmed after assessment.
