Subdividing Your Block in Sydney? Here's When You Need a New Private Power Pole

Does a subdivided battle-axe or rear lot in Sydney need its own private power pole? In most cases, yes. Once a block is split into two separate titles, the new rear lot usually cannot reach the street with a standard overhead service, and the Service and Installation Rules of NSW (SIRNSW) specifically provide for this by allowing a private pole where crossing the front lot would otherwise be needed. Get the pole sorted early, because Ausgrid or Endeavour Energy won't connect the new title without an approved point of supply in place.

⚡ Quick Answers: Private Power Poles for Subdivided Blocks

• Why does a battle-axe subdivision need a private pole? SIRNSW Clause 3.7.2.1 specifically allows a private pole to provide supply to a battle-axe block, on top of the usual reasons (no suitable spot on the building, excessive span, or avoiding a crossing of a neighbouring property).
• Who pays for the new pole? The owner of the new lot. A private pole and everything from the point of supply onward is a private asset, separate from Ausgrid or Endeavour Energy's own network poles.
• Can I run a cable across my other lot instead of installing a pole? Only if that stays part of the same title. Crossing a separate lot needs a registered easement, and even then a suspended mid-span service is treated as a last resort, capped at 100A and 20m with written network approval every time.
• How deep does the new pole need to be set? SIRNSW Table 3-5 sets the sinking depth by soil quality and pole height, generally in the 1 to 1.9 metre range, and soft or filled ground may need a structural engineer's certified footing instead of standard depth.
• Do I need council approval as well as the network's? Usually yes. Most subdivisions already carry council development consent, and the private pole itself often needs its own separate council sign-off before it goes in the ground.
• Does the pole affect my subdivision certificate? It can. The electrical connection is one of several servicing authority conditions a subdivision certificate depends on, so leaving it until late in the build is a common and costly mistake.

1. Why a subdivision so often creates a private pole problem

Subdividing a Sydney block, whether a straight Torrens title split or a battle-axe arrangement with a rear lot behind a narrow access handle, creates a second legal title where there was one. Each title needs its own independent point of supply. The original house usually keeps its existing connection, but the new lot rarely has street frontage close enough for a standard overhead service, and running a cable across the front lot to reach it means crossing land you no longer own.

This is exactly the situation SIRNSW anticipates. Clause 3.7.2.1 sets out when a private pole is required, and a battle-axe block missing direct street access is one of the named scenarios, alongside no suitable point of attachment on the building, an excessive span back to the network's pole, and the need to avoid crossing adjacent premises altogether.

2. What the rules actually require

A private pole for a subdivided lot has to meet the same construction rules as any other private pole, plus a few requirements that matter more on a subdivision. It must sit within 1 metre of the front property boundary and be clearly labelled "PRIVATE POLE" in lettering at least 20mm high, so network crews and future tradespeople can tell it apart from a distributor asset at a glance. If the point of attachment on the pole exceeds 6.7 metres, climbing steps have to be fitted as well.

The installer also has to send the network an as-built sketch of the finished route, including pole position and boundary measurements, as part of the Notification of Service Work. On a subdivision, that sketch typically forms part of the paperwork the surveyor and council are also relying on to sign off the new title, so accuracy matters more than usual.

3. Alternatives most subdivisions rule out

Before committing to a pole, it's worth understanding why the other options usually don't work. Running the service across the retained front lot to the rear title needs a registered easement, which not every vendor or council process is set up to grant cleanly, and it leaves the rear lot's supply dependent on infrastructure sitting on someone else's land. A suspended, mid-span service between two structures is technically possible but is treated as a genuine last resort in the rules, limited to 100A and 20 metres and requiring the network's written approval for that specific span, not a standing entitlement you can rely on for planning purposes.

For most battle-axe and rear-lot subdivisions, a private pole ends up being the simpler, more durable answer: it sits on the new lot's own title, it's sized and built to a known standard, and it doesn't depend on an easement surviving future ownership changes on the front block.

4. Setting the pole correctly for the soil you've actually got

Sinking depth isn't a single number. SIRNSW Table 3-5 scales the required depth to both the pole's height above ground and the soil quality on site, which is why a soil assessment early in the subdivision process saves a lot of back and forth later. Where the ground won't take the standard depth, whether that's rock close to the surface, fill, or a high water table, the rules allow an alternative footing such as a flange-mounted base on a reinforced concrete structure, but only with a structural engineer's certification confirming it meets the strength and durability requirements before construction proceeds.

Pole material matters too. Timber poles need durable, graded hardwood treated against rot and termites at the base and capped to keep water out; steel poles need to be sized to the standard's tables and hot-dip galvanised, with any damage to the coating patched with zinc-rich paint rather than left bare.

5. Underground versus overhead for the new lot

A subdivision is also a natural point to consider running the new lot's service underground instead of overhead, particularly if the rear title will eventually be built out with a driveway, landscaping or a granny flat where an overhead line and pole would be in the way long term. Underground consumers mains have their own cable size and construction requirements under SIRNSW, and any pit or pillar used as the termination point needs clear access from two sides and above, with a fully removable lid and the lid itself permanently marked "CAUTION ELECTRICITY" and "PRIVATE PIT" or "PRIVATE PILLAR."

Overhead is usually cheaper and faster to install, which is why most subdivisions still end up with a private pole rather than a full underground run, but it's worth pricing both before locking in the site plan, especially if the new lot sits in a bushfire-prone area, where the network can require overhead mains to be built and maintained to stricter bushfire management standards, or order defective private lines and vegetation cleared at your cost.

6. Approvals before the network will connect

A private pole for a new title needs sign off from more than one authority before supply is actually turned on. Council development consent for the subdivision itself usually comes first, and the pole and any associated works may need their own separate council approval depending on your local government area. On the network side, an accredited Level 2 ASP has to lodge the connection application and Notification of Service Work, and the network typically won't finalise the new title's connection until that paperwork, including the as-built sketch, has gone through.

If you're unsure which network your subdivided lot falls under, check your network area in seconds with our postcode checker before you start pricing the job, since Ausgrid and Endeavour Energy handle some of these requirements slightly differently.

7. A realistic sequence and timeline

Most subdivision pole jobs follow a similar order: council development consent and the subdivision plan come first, then a site assessment to check soil conditions and confirm pole position against the 1 metre boundary rule, then the connection application and design lodged with the network, then a Dial Before You Dig check before any excavation, then the pole installation itself, then testing, energising and the as-built sketch submission. Depending on council and network processing times, the electrical component of a subdivision can run from a few weeks for a straightforward suburban block to considerably longer where soil conditions, bushfire overlays or heritage controls add extra approval steps.

8. What happens if this gets left until late in the build

The most common costly mistake isn't a technical one, it's sequencing. Builders and owners sometimes leave the electrical connection for the rear lot until the house is nearly finished, only to find the subdivision certificate is being held up by an outstanding servicing authority condition. Because the pole position, depth and route all depend on decisions made earlier in the site plan (driveway location, landscaping, any future granny flat), retrofitting a pole after the build is well underway is almost always more expensive and slower than planning for it alongside the subdivision application itself.

Why it's Level 2 ASP work

Connecting a new title to the network, including installing and energising a private pole, is contestable connection work under the accreditation scheme, meaning only an accredited Level 2 ASP can lawfully carry it out. That covers the design, the pole installation itself, testing polarity, phase rotation, insulation and earthing once finished, and lodging the paperwork the network relies on to approve the new supply. A standard electrician who isn't Level 2 accredited can't legally do this work, even if they're licensed for general domestic and commercial electrical jobs.

Subdivision Private Power Pole FAQs (Sydney)

Does every subdivided lot need a new private pole?

Not always. If the new lot has genuine street frontage close enough for a standard overhead or underground service without crossing the other title, a pole may not be needed. A site assessment against SIRNSW's distance and access rules is the only reliable way to confirm this. See the main site's private power pole installation service for what that assessment covers.

Can I use the existing pole from before the subdivision?

Sometimes, if it's positioned correctly relative to the new boundary and still meets current depth and labelling requirements, but boundaries created by a subdivision often leave an existing pole in the wrong spot relative to the new title line, which means a new or relocated pole is required instead.

How much clearance does the pole need from the boundary?

SIRNSW requires a private pole to stand within 1 metre of the front property boundary, which is a fixed positioning rule rather than a rough guide, so it needs to be factored into the site plan alongside driveways and landscaping.

Who do I call if I'm not sure whether I need a pole at all?

An accredited Level 2 ASP can assess the site plan and confirm whether a pole, an underground connection, or neither is required before you finalise your subdivision application. See the main site's Level 2 electrician Sydney page for what that assessment involves, and its Level 3 design service if the network requires a formal design submission for a more complex site.

What if my new lot is in a bushfire-prone area?

The network can require overhead mains in declared bushfire areas to meet stricter bushfire management requirements, and can order defective private lines or overgrown vegetation to be fixed at your cost. Worth checking this early with your Level 2 ASP if your subdivision sits in a bushfire overlay area.
