Do You Need a Campervan Electrician? Work and Checks

Use a competent installer where the design, mains work, fault diagnosis or verification exceeds your skills, and agree the handover evidence before work starts.

Most of your campervan electrical system can be installed yourself — but some parts really should be done by a qualified professional. Understanding where the line falls can save you money while keeping you safe.

Design before you build

Our free calculator designs your complete system, so you know exactly what needs installing before you start — or before you brief an electrician.

What You Can DIY Safely

All 12V DC work is generally safe for competent DIYers:

12V battery installation — mounting, wiring, and fusing
DC-DC charger wiring — following manufacturer instructions
Solar panel mounting and wiring — roof panels to MPPT controller
12V distribution — fuse box, LED lights, USB sockets, water pump
Battery monitoring — SmartShunt, Victron BMV setup

The key with 12V work is using the correct wire gauges and fuse sizes. Our wire gauge calculator handles this automatically, and our fuse sizing guide explains the 125% rule.

What Needs a Professional

230V AC Wiring

Any mains voltage (230V) work should be done or at minimum inspected by a qualified electrician. This includes:

Consumer unit wiring — RCD, MCBs, and earth bonding
230V socket installation — connecting to inverter output
Shore power inlet and hookup — mains input to charger/consumer unit
Earth bonding — critical safety requirement

230V can kill

Mains voltage is lethal. In the UK, there's no legal requirement for a qualified electrician to do campervan 230V work (unlike domestic properties), but the safety risk makes professional installation strongly advisable. At minimum, have a qualified electrician inspect your work.

When to Hire for 12V Too

Consider hiring a professional for 12V work if:

You've never done any electrical work before
Your system is complex (multiple batteries, high-current inverter)
You want insurance-compliant documentation
You're selling the van commercially

Finding a Campervan Electrician

Look for electricians who specifically advertise campervan/motorhome work. They'll understand the unique challenges (mobile environment, vibration, vehicle earthing) that a domestic electrician may not.

Expect to pay: £300-£500/day for a specialist campervan electrician in the UK.

Get a certificate

If you have a professional do your 230V work, ask for a test certificate. This documents that the installation has been tested and meets safety standards — useful for insurance and resale.

FAQ

Is there a legal requirement for a qualified electrician in a campervan?

In the UK, there's no legal requirement like Part P for domestic properties. However, if your van is used commercially or needs an MOT with electrical systems, having professional documentation is valuable.

How much does a campervan electrician cost?

Specialist campervan electricians typically charge £300-£500 per day. A full 230V installation (consumer unit, sockets, shore power inlet) usually takes 1-2 days.

Can I do the 12V work myself and hire an electrician for 230V only?

Absolutely — this is the most common approach. Do all the 12V work yourself, then bring in a professional for the consumer unit, RCD, and 230V sockets.

Worked planning check

Prepare a review pack with the load list, schematic, equipment manuals, cable/fuse schedule, mounting photographs and unresolved questions. Ask the installer to separate design review from inspection and live commissioning. Paying for a brief review is not the same as having the completed system tested.

The figures or dimensions in this example are explicit planning assumptions, not a product test or an installation specification. Replace them with your equipment data and actual measurements.

Planning questions

Can I choose a fuse just from the appliance current?

No. Check cable ampacity under the installed conditions, equipment instructions, terminal limits, DC voltage and interrupt capacity. Protection must coordinate with the complete circuit.

Does a wiring diagram prove the installation is safe?

No. It is a planning record. Actual routing, termination, protection and commissioning results must agree with the design and applicable requirements.

When should I involve an electrician?

Before work that exceeds your competence, particularly mains design, source transfer, bonding, high-current faults and final inspection or testing. Agree the scope and evidence of verification in advance.
