Greg from Hang Loose was great, he turned up on time and was able to resolve my electrical issues on my new boat. I would have no hesitation in reccommending Hang Loose for marine electrical work.

Marine auto electrician: common questions
Can't see your question? Call 0492 268 126 and talk to the team.
What does a marine auto electrician do?
A marine auto electrician works on a boat's low-voltage DC system: batteries, charging, dual-battery setups, lithium house banks, inverters and the 12V or 24V wiring that runs everything on board. Hang Loose Electrical does this work at our Clontarf workshop, with larger jobs at your marina or home by arrangement.
Do you work on 24V as well as 12V?
Yes. We are 12V and 24V specialists for batteries, charging and dual-battery installs.
Can you fit a dual-battery system to my boat?
Yes. We design and install dual-battery systems so your start battery stays ready while the house battery runs your gear. You get a clear quote first.
Where do you do the work?
Yes, we can come to you, but surcharges apply compared with getting the work done at our Clontarf workshop. Most battery and charging jobs are best done at the workshop; larger jobs can be done at your marina or home. For breakdowns after hours, call Michael on our 24/7 breakdown line. Surcharges apply for 24/7 emergency callouts and for callouts to your marina or wherever the boat is located.
Is the work guaranteed?
Yes. We are licensed and insured, bring 50+ years combined experience, and back our workmanship with our satisfaction guarantee. We confirm the terms in your quote.
