Underground Service Connection & Mains — Sydney Level 2 Electrician

An underground service connection brings power from the network to your property through underground consumer mains — from a network pit or pillar, or down a pole and underground (a UGOH connection). Installing, converting, upgrading or repairing that underground service is Level 2 ASP work. Sydney Electrical Service is a licensed Ausgrid Level 2 ASP (licence 236351C). We design and install underground service connections across Sydney — new connections, overhead-to-underground conversions, capacity and phase upgrades, and repairs to damaged underground mains — and lodge the Certificate of Compliance on completion. Available 24/7.

What's Involved

Underground service work covers the buried consumer mains on the network side of your meter:

• New underground connections from a network pit or pillar for new builds, granny flats, knock-down-rebuilds and subdivisions.
• Overhead-to-underground (UGOH) conversions — removing the overhead service and bringing the supply down a pole and underground, for a cleaner frontage or to clear a build.
• Upgrades — larger underground mains or a move to three-phase supply.
• Repairs — locating and repairing damaged or faulted underground mains (often after excavation strikes or ageing cable failure).
• Conduit, pits and trenching coordination to Ausgrid’s underground rules.

As a Level 2 ASP we handle the network disconnection and reconnection, so it’s one coordinated job.

Reasons to Use This Service

• Licensed Ausgrid Level 2 ASP (236351C) — authorised for underground network connections and disconnections.
• Full scope handled — design, conduit and pits, cable, terminations, plus the network disconnection and reconnection.
• Certificate of Compliance (CCEW) lodged on completion.
• Clear, fixed-price quotes with trenching and restoration scoped up front — no mid-job surprises.

Our Process

1. Site assessment. We confirm the network connection point, the run, trenching and the phases/capacity required.
2. Fixed-price quote. Including conduit, cable, pits and any trenching or boring.
3. Network disconnection. We isolate the existing supply at the network where needed.
4. Install the underground mains. Conduit, cable and terminations to Ausgrid's underground rules.
5. Test, reconnect & certify. We energise, test, reconnect to the network and lodge the CCEW.

NSW Compliance

Underground service connections to the network are Level 2 Accredited Service Provider (ASP) work under the NSW network rules. Sydney Electrical Service is an accredited Ausgrid Level 2 ASP (licence 236351C). Cable sizing, conduit depth, pits and terminations follow AS/NZS 3000 and Ausgrid’s underground service and installation rules, and we lodge a Certificate of Compliance for Electrical Work (CCEW) on completion.

Pricing Approach

Underground connections are quoted as a fixed price once we’ve confirmed the run length, trenching, the network connection point (pit or pillar) and the phases needed. We flag any trenching, boring or restoration scope up front so the price is clear. Call 0433 462 902 for a fixed-price quote.

Sydney-Specific Considerations

Underground supply is the norm for newer Sydney estates and is increasingly chosen for renovations and knock-down-rebuilds across the city for a cleaner look and to clear overhead obstructions. We work to Ausgrid’s underground rules and coordinate trenching around Sydney’s services, driveways and landscaping.
