Low Hanging Power Lines? Fix the Clearance Before Something Finds It
A sagging service line looks harmless — until a truck, a trailer, a ladder or a teenager with a pool scoop finds it. Powerline clearance heights exist because low lines injure people and rip connections off houses. High Demand Electrical re-tensions, re-routes and rebuilds low hanging power lines across Sydney, with 24/7 response when a line is dangerously low.

How Low Is Too Low?
NSW service rules set minimum clearances for good reason. You don't need to measure precisely — these rough checks tell you whether to book us or call us now on 0402 559 777.
- Over driveways, lines should clear high vehicles comfortably — if a truck or caravan could touch it, it's too low.
- Over yards and paths, lines must be well above head height with margin — reachable with a raised hand is an emergency.
- Near decks, pools or trampolines — any line a person could touch during normal activity needs urgent attention.
- Sagging suddenly after heat, storm or contact — the conductor or its anchors are failing; treat as urgent.
What to Do About a Low Line
Until it's fixed, the line is a contact hazard — manage it like one.
Keep people, vehicles and equipment clear
No ladders, no pool poles, no high loads under the sag — and warn the household.
Never try to lift or prop a line
Even a well-insulated-looking line can be damaged and live — nothing you own is safe to touch it with.
Check what changed
New sag usually has a cause — heat stretch, storm, tree contact or a failing anchor. Tell us what you noticed.
Photograph it from the ground
A photo helps us triage severity and bring the right hardware first visit.

Dangerously low lines get 24/7 response; borderline clearances get a prompt booked visit — we'll tell you honestly which yours is.
Why Lines End Up Low
Sag has causes — and fixing the cause is what stops it returning.
Conductor Stretch Over Time
Decades of heat cycles permanently elongate conductors — old lines sag lower every summer.
Failing Points of Attachment
Corroded brackets and pulling fascia let the line drop at the building end — a precursor to complete tear-off.
Leaning or Settling Poles
A pole tipping toward the span slackens the line — see leaning power pole.
Tree and Branch Contact
Limbs resting on the span push it down and abrade the insulation — double hazard.
Vehicle Snags
A truck that clipped the line stretched it — even if it stayed up, the clearance and hardware are compromised.
Undersized or Aged Spans
Long spans on old hardware sag beyond standard — sometimes the honest fix is a new mid-span pole or an underground conversion.
How We Restore Safe Clearance
Service line work is Level 2 — we handle everything from a simple re-tension to full re-routing.
- Line re-tensioning to compliant clearance heights
- Point-of-attachment rebuilds — new brackets, anchors and terminations
- Conductor replacement where stretch or damage is beyond re-tensioning
- Mid-span private pole installation for long spans
- Overhead-to-underground conversion where clearance can't be achieved
- Certification and coordination with the network where required

FAQs
What is the minimum height for power lines over my property?
Minimum clearances in NSW vary by location — higher over driveways and vehicle areas than over open ground — and are set by the service rules. As a practical rule: if a person, vehicle or piece of equipment you'd normally use could contact the line, it's non-compliant and dangerous. We measure exactly and quote the fix after a free inspection. Call 0402 559 777.
Can I just push the line up out of the way?
Never. Service lines carry full mains voltage, insulation on old conductors is often perished, and contact through any object can be fatal. Clearance is restored by re-tensioning or rebuilding the span — Level 2 work our crews do routinely and safely.
Whose job is it to fix a low service line — mine or the network's?
The service line from the street to your house, and anything on a private pole, is the property owner's responsibility — repaired by Level 2 ASPs like us. Sagging street mains between network poles belong to Ausgrid or Endeavour Energy. Send us a photo and we'll tell you which in seconds.
