An electrical survey gives you a clear, written picture of the condition and safety of your boat's electrical system, so you can plan work rather than react to failures.
Boats collect electrical changes over the years. Circuits get added, equipment is swapped, and not every job is done to the same standard. A dedicated electrical survey looks at the whole system in more depth than a general condition survey can, and tells you what is safe, what needs attention and what can wait.
This page covers our survey service for owners who want to know where they stand, whether after a winter ashore, before a refit or ahead of a longer passage. If you are about to buy a boat, our pre-purchase electrical survey guide explains how an inspection fits into a purchase and how to use the findings.
The most common triggers are unexplained faults, a planned refit where you want to know what can be reused, an insurer or marina asking about the condition of the electrics, or simply having bought a boat and wanting to understand what previous owners have done. A survey is also a sensible first step before adding lithium, solar or an inverter, because it shows whether the existing wiring can support the change.
We work through both the DC and AC sides, from the batteries and charging sources to the distribution panels and the shore power inlet. Testing uses proper diagnostic equipment rather than a quick visual walk-round, so hidden problems such as voltage drop, poor connections and leakage show up.
You receive a written report that separates genuine safety issues from recommended improvements and items to monitor. Each finding is explained in plain terms, with why it matters, so you can make decisions without needing to be an electrician. If you want us to carry out any of the work afterwards, we quote it separately in writing; there is separate agreement.
A pre-purchase inspection is about risk before you commit money, and is often done against a deadline set by the sale. The service survey described here is for a boat you already own, so we can take more time, open up more of the installation with your agreement and plan a prioritised programme of work with you. The inspection methods overlap, but the purpose and the report are shaped differently.
The testing overlaps, but this service is for boats you already own and focuses on planning work. Our pre-purchase guide covers inspections before buying.
No. The report is yours to use as you choose. If you want us to do the work, we quote it separately in writing.
Yes. We check the shore power inlet, RCD protection and polarity as part of the AC side of the inspection.
