Consumer Mains Upgrade and Replacement Sydney
Level 2 Accredited Electricians. Trading Since 1999.
Your consumer mains are the cables that bring power from the street to your meter and main switch. Every amp your home or business uses runs through them. When they’re old, damaged or too small for the load, the whole property suffers.
Dave Fenech Electrical Services has been replacing and upgrading consumer mains across Sydney since 1999. We’re a licensed and insured Level 2 Accredited Service Provider on the Ausgrid and Endeavour Energy networks, so we can disconnect your supply, replace the mains and connect you back to the network ourselves.
What Are Consumer Mains?
The Cable Between the Network and Your Switchboard
Consumer mains run from the point where the network supply reaches your property to your meter and main switch. On an overhead service, they start at the point of attachment on your house or a private pole. On an underground service, they start at the pit or pillar near your boundary. The property owner is responsible for them, and only a Level 2 electrician can connect them to the network.

Signs Your Consumer Mains Need Replacing
Mains cable is built to last for decades, but it doesn’t last forever. Sun, heat, water and movement break down the insulation, and many older homes still run on cable sized for a fraction of what they use today. If you notice any of these, have the mains checked by a Level 2 electrician before the problem turns into an outage or a fire.
Damaged or Brittle Insulation
Cracked, perished or scorched cable where the mains enter the roof, riser or meter box.
Dimming Lights and Power Loss
Lights that dim when big appliances start, or a supply that drops out when the house is under load.
A Defect Notice
The network has inspected your service and issued an electrical defect notice.
New Heavy Loads
Ducted air, an EV charger, a heat pump or an extension that the old mains can’t carry.
Overhead vs Underground Consumer Mains
Most Sydney homes have one of two types of service. We install, repair and replace both.
Overhead consumer mains. The network’s service line runs from the street pole to a bracket on your house, called the point of attachment. From there, the consumer mains run down a riser or through the roof space to the meter box. When we replace overhead mains, we check the point of attachment bracket and riser at the same time, because a rusted or loose bracket is a common defect. If your service runs to a private pole that’s rotten or leaning, we can also do a power pole replacement.
Underground consumer mains. The cable runs from a pit or pillar near the boundary, through heavy duty conduit buried in a trench, to your meter box. Underground mains are protected from storms and trees, but they can be damaged by digging, tree roots and water getting into old cable. Our underground electrical team does the trenching, conduit and cable in one job. Not sure which suits your property? Our guide to underground or overhead power lines compares the two.
Upgrading for 3 phase or bigger loads. Many older homes were connected with smaller cable sized for lights and a few appliances. If you’re adding ducted air, a pool heat pump, an EV charger or a granny flat, the mains may need to go up a size. A single phase to three phase upgrade always needs new consumer mains, because the old cable only carries one phase.
Our consumer mains work includes:
- Replacing old, damaged or undersized consumer mains
- Upgrading mains for 3 phase power, extensions and new heavy loads
- Converting overhead services to underground
- Point of attachment brackets, risers and private poles
- Defect notice repairs on mains and service equipment
- Emergency repairs to storm, tree and fault damage
- Network notices and compliance certificates lodged for you
Why Sydney Homeowners Choose Dave Fenech Electrical Services
We’ve been trading since 1999. Consumer mains connect to the network, so a regular electrician can’t finish the job. As an accredited Level 2 Service Provider, we do the disconnection and reconnection ourselves, so you’re not waiting on a second contractor.
New mains often need work at the switchboard end too. If your board still has old fuses or no safety switches, we can do a switchboard upgrade on the same day so the job’s done once. We also handle electricity meter installation and meter box replacements across Sydney.
Our Promise: We turn up when we say we will, keep you informed at every step, and leave your property safely connected to the network.

How a Consumer Mains Replacement Works
You make one booking and we organise the rest, including the network side.
Step 1: Book a site visit online or give us a call.
Step 2: We check your service, the cable route, the meter box and the switchboard, then give you a fixed quote.
Step 3: We lodge any network paperwork and book a day that suits you.
Step 4: We disconnect the supply, install the new mains, test everything and connect you back to the network.
Your power is off while the old mains are swapped over. We tell you how long when we quote, and agree the time with you first so you can plan around it.
What Affects the Cost of Consumer Mains Replacement
Every property is different, so we price consumer mains work after we’ve seen yours. These are the main things that change the price.
- Length of the cable run. The further your meter box is from the point of attachment or the pit, the more cable and labour the job needs.
- Overhead or underground. Underground mains need trenching, and boring under driveways or paths adds time. Overhead mains may need a new bracket, riser or private pole.
- Cable size. Bigger cable for a 3 phase supply or heavier loads costs more than a like-for-like replacement.
- Meter box and switchboard. An asbestos meter panel or an old fuse board often has to be replaced so the new mains can be connected safely.
- Access. Two storey homes, tight roof spaces and concrete or landscaping along the cable route all affect the labour.
If you’ve had a defect notice, the network sets a deadline for the repair, so get a quote early. If you’re planning solar, an EV charger or a 3 phase upgrade, tell us when you book and we’ll quote the whole job together. Quotes are free.

Consumer Mains FAQs
What are consumer mains?
Consumer mains are the cables that run from the network’s connection point at your property to your meter and main switch. On an overhead service, they start at the point of attachment on the house or a private pole. On an underground service, they start at the pit or pillar near the boundary. They carry all the power the property uses.
Who is responsible for consumer mains in NSW?
The property owner. The network owns and maintains the street side of the supply, but the consumer mains, the point of attachment bracket, any private pole and the meter box are the owner’s responsibility. If they’re damaged or defective, the owner pays for the repair, and the work has to be done by a Level 2 electrician.
What size is a consumer mains cable?
It depends on the load, the length of the run, how the cable is installed and whether the supply is single or three phase. Many older homes have smaller cable than a modern home needs, sized for lights and a few appliances. We work out the right size for your property under the wiring rules and the network’s service rules, then quote on that.
How much does consumer mains replacement cost?
It depends on the length of the cable run, whether the mains are overhead or underground, the cable size and whether the meter box or switchboard also needs work. A short like-for-like overhead replacement sits at the lower end. A long underground run under a driveway or an upgrade to three phase costs more. We inspect first and give you a fixed quote in writing.
What is the difference between consumer mains and sub mains?
Consumer mains run from the network connection point to the main switchboard. Sub mains run from the main switchboard to a second board somewhere else on the property, such as a granny flat, shed, garage or pool house. We install both. Our granny flat metering page explains the options for a second dwelling.
Do I need a Level 2 electrician to replace consumer mains?
Yes. The mains have to be disconnected from and reconnected to the network, which is Level 2 work. Only an Accredited Service Provider can do it. We’re Level 2 accredited and licensed electricians, so one team does the whole job.
Can you repair consumer mains instead of replacing them?
Sometimes. A loose connection, a damaged section of conduit or a rusted bracket can often be repaired. If the cable insulation has broken down, the cable is too small for the load or it has been damaged along its length, replacing it is the safe fix. We’ll tell you which applies when we inspect.
Do you do emergency consumer mains repairs?
Yes. If a storm, a falling branch, a vehicle or digging has damaged your mains, stay clear of the cable and call the network’s emergency line first if anything is down or sparking. Then call us on 02 9833 9566 and we’ll tell you how quickly we can get there to repair it and get the power back on safely.
What happens if I get a defect notice for my consumer mains?
The network inspects services and issues a defect notice when it finds a problem, such as damaged mains, a rusted point of attachment or a rotten private pole. The notice sets a deadline for the repair. We fix the defect and lodge the paperwork with the network. Our defect notice page has more detail.
Do I need new consumer mains for 3 phase power?
Yes. Single phase mains only carry one phase, so a three phase upgrade always means new mains, plus a three phase meter and usually a new switchboard. See our single phase to three phase upgrade page for how it works.
Can I move my overhead mains underground?
Yes, in most cases. We dig a trench from the pit or pillar to the meter box, lay the cable in conduit and connect it, then the overhead service is removed. Whether it’s possible depends on the network having underground supply in your street. We’ll check that before we quote.
What is neutral screened cable?
Neutral screened cable has the active conductor in the centre and the neutral wound around it as a screen. It was widely used for services and mains in older installations. When the screen corrodes or the insulation breaks down, it can cause supply faults and shocks, and it’s a common reason we replace old mains.
Will my power be off while the mains are replaced?
Yes, for part of the day. The supply has to be disconnected while the old mains are removed and the new ones connected. We tell you how long when we quote, agree the time with you, and test everything before the power goes back on.
Which parts of Sydney do you cover?
We cover all of Sydney from our base in St Marys, including Penrith, Blacktown, Mount Druitt, Parramatta, the Hills District, Liverpool, Bankstown, Campbelltown and the suburbs in between. Book a site visit and we’ll look at your mains and give you a quote.
Will I get a compliance certificate?
Yes. We test the installation before the power goes back on and issue a Certificate of Compliance for Electrical Work. We also lodge the required notices with Ausgrid or Endeavour Energy. Keep the paperwork with your property records, as insurers and future buyers can ask for it.
