52 Florida-licensed low voltage / limited energy subcontractors serve Jacksonville (Duval, St. Johns, Clay & Nassau Counties). Browse listings below, or create a free* GC account to see phone and email and invite a sub to bid on your RFQ.
Most of these low voltage / limited energy subcontractors are based in Jacksonville (24), Middleburg (4), Ponte Vedra (4), Saint Augustine (4), Yulee (3), and Keystone Heights (2) — plus 11 more across the metro.
Low voltage subcontractors handle the limited-energy systems in a building — data and communications cabling, structured cabling and telecom rooms, security and access control, CCTV and surveillance, audio/video and paging, and intercom systems. On commercial jobs they price from the technology and security drawings and spec, coordinate with electrical for power and pathway and with fire alarm where interconnects are required, and pull permits and schedule inspections on their portion of the work.

When a GC sends a low voltage RFQ, they're usually looking for a quote against a defined scope: the technology and security drawings with the Division 27 and 28 spec sections, a clear inclusion and exclusion list (structured cabling, racks, access control heads and panels, cameras, AV, paging, testing and certification), and the sub's read on long-lead items like specialty cameras and door hardware integrations. For bid prep a GC typically wants pricing broken out enough to compare apples-to-apples, confirmation the sub priced to the spec book, and the sub's license and insurance on file.
Low voltage contracting in Florida is a state-licensed specialty, regulated by the Electrical Contractors' Licensing Board (ECLB) under the DBPR — distinct from a general electrical contractor's license. Low voltage subs typically hold a limited-energy specialty license (prefix ES with the ENRG class code) that scopes them to data, communications, security, audio/video, and other limited-energy systems. Florida treats unlicensed contracting as a crime, so a GC confirming a sub's active ECLB limited-energy license is doing basic bid-prep diligence — which is why every low voltage sub in this directory carries its DBPR license number.
Yes. Low voltage and limited-energy work is regulated statewide by the Electrical Contractors' Licensing Board (ECLB) under the DBPR. Low voltage subs typically hold a limited-energy specialty license (prefix ES with the ENRG class code), distinct from a general electrical contractor's license.
Not by default. Low voltage is a separate limited-energy specialty under the ECLB. A sub doing data/comm, security, audio/video, or structured cabling in Florida typically holds the limited-energy specialty license rather than the general electrical (EC or ER) license.
The technology and security drawings and Division 27 and 28 spec sections, a scope inclusion and exclusion list (structured cabling, racks, access control, cameras, AV, paging, testing and certification), any long-lead items, the bid deadline, and whether a site visit is required.
Yes. GCs post an RFQ and invite matched subs by trade and service area; invited subs are notified and can submit a bid for your bid prep.
Listings are seeded from public Florida DBPR license data, and a sub can claim its listing and upload a credential for a one-time review. The badge reflects what was reviewed: a verified state license earns License Verified — the usual path for a low voltage sub — a verified certificate of insurance earns Insurance Verified, and a sub with both reviewed shows the Verified Pro umbrella.
