Most Perth sparkies undervalue their scrap copper by $2-$6 per kilogram simply because they’re not sorting it correctly. Over the course of a busy year , wiring new homes in Rockingham, pulling old cable from commercial fit-outs in Kwinana, commissioning switchboards in Henderson , that gap adds up to hundreds or potentially thousands of dollars left at the yard.
This isn’t about being precious with your off-cuts. It’s about spending five extra minutes on the van at the end of a job and getting paid accordingly. Here’s exactly how to do it.
The grades that matter for electricians
Most of what comes off electrical work falls into three categories. Understanding which is which is the foundation of getting the best price.
Bare-bright copper wire , the top grade
This is clean, stripped, uncoated copper wire with no insulation, no oxidation, no solder, and no attachments. Think off-cuts of stripped single-core house wire, short lengths of bare earth wire, or anything you’ve already stripped on the job.
Bare-bright is paying $11-$13/kg in Perth right now. It’s the highest-paying scrap metal at most Perth yards. If you only have one bin in your van, strip as you go and aim for this grade as much as possible.
Insulated copper wire , where the opportunity is
Standard house wiring still in its plastic sheath , TPS (twin and earth), single-core PVC insulated, flex cord , typically pays $4-$7/kg. The cable itself is full of quality copper, but the plastic sheathing is factored against you.
Here’s the opportunity: strip TPS cable to bare-bright and you move from $4-$7/kg to $11-$13/kg. On a 10kg bag, that’s roughly $40-$90 extra. On a month’s worth of pull-outs from a large renovation, that can be several hundred dollars.
Heavy insulated cable , the most common quantity
Armoured mains cable, multi-core industrial cable, and SWA are worth scrapping but pay less per kilogram than stripped wire , typically $3.50-$6/kg depending on copper content and insulation type. The heavy insulation and steel armour reduce the grade. These aren’t typically worth hand-stripping unless you have a machine stripper.
Setting up a simple collection system on the van
The biggest barrier to getting top dollar on copper scrap is throwing everything in one bag and sorting it later , which usually means not sorting it at all.
A straightforward system: two buckets in the van. One for stripped/bare material, one for insulated cable. If you strip as you go on the job (which many sparkies do anyway when cutting to length), the bare copper goes directly in the bare bucket.
At the end of each job, take the insulated pull-outs: TPS and single-core house wire that’s worth stripping goes in the strip queue. Heavy armoured cable that’s not worth hand-stripping goes in a separate bag.
The ten-minute Friday afternoon process: take your strip queue for the week, run it through a stripper tool, and add the bare-bright to your bare bucket. By the time you’ve got 10-15kg of bare-bright, you’re looking at $110-$195 from material that started as $4-$7/kg insulated cable.
What to do with switchboard components and fittings
Old switchboard cleanouts are some of the most valuable scrap runs for Perth sparks. They tend to contain:
- Copper busbar , this is essentially bare-bright grade copper and pays accordingly ($11-$13/kg)
- Copper cable tails and connections , strip the insulation and add to your bare-bright bucket
- Aluminium cable tray and conduit , worth keeping separate; aluminium pays $1.60-$2.20/kg
- Old fuses and ceramic components , check whether they contain significant copper before discarding
- Steel cabinet frames , ferrous, lower value per kg but worth keeping separate from non-ferrous
Never mix your copper busbar with steel cabinet parts. It’s the most common mistake on switchboard cleanouts and it costs real money.
Aluminium wiring and conduit , keep it separate
Perth still has older homes and some commercial buildings with aluminium wiring , particularly from the 1960s and 1970s. Aluminium wire pays $1.60-$2.20/kg as clean extrusion, which is significantly less than copper but still worth segregating and selling properly.
Aluminium conduit and cable tray off new commercial work also adds up quickly on large jobs. A fit-out in a Kwinana warehouse or an Henderson industrial unit can easily yield 30-50 kg of aluminium conduit. At $1.80/kg, that’s $54-$90 for material that’s otherwise going in a skip.

When stripping is worth your time and when it isn’t
The honest answer: stripping is worth it for thick single-core and twin-core house wire. It isn’t always worth it for very thin data or communication cable.
Here’s a rough guide:
- Standard 2.5mm TPS (twin and earth): worth stripping. Good copper content, strips quickly.
- 4mm and 6mm single-core: definitely worth stripping. High copper content per metre.
- 10mm and above: if you have a stripper tool, absolutely. Heavy copper content.
- 1.5mm TPS: borderline , strip if you have the right tool, skip if it’s slow going.
- Data cable (Cat5/6, phone cable): usually not worth stripping , very thin conductors, labour-intensive.
- Flex cord (appliance leads): strip the outer sheath for multi-core copper inside , worth it for volume.
If you’re doing any volume of wiring work in Perth, a decent bench-top manual wire stripper is a solid investment. They pay for themselves quickly once you’re pulling regular quantities of house wiring.
The logistics: when to come in and what to expect
We’re at 49 Burlington Street, Naval Base , which puts us conveniently between the Rockingham and Kwinana industrial areas, and easy access from Henderson via the Rockingham Road. Most Perth sparks covering the southern suburbs can be in and out in 15-20 minutes.
What to expect when you arrive: drive in, we’ll help unload your bags and buckets, each grade gets weighed separately on our certified scales, you get a price per grade, and payment is on the spot. Bring your driver’s licence , it’s required at all licensed WA yards.
For regular sellers, it’s worth calling ahead with an approximate weight and grade breakdown. We can give you an indicative price over the phone for the day’s rates so there are no surprises at the weigh-bridge.
Frequently asked questions from Perth sparks
What is the best price for copper wire scrap in Perth right now?
In mid-2026, clean stripped (bare-bright) copper wire is paying approximately $11-$13/kg at Perth yards. Insulated house wiring still in its sheath pays $4-$7/kg. The difference is the stripping , and it’s worth doing for any significant quantity of TPS or single-core.
Is it worth buying a wire stripper if I’m a sparky?
For most Perth electricians doing residential or commercial work, yes. A manual bench-top wire stripper costs $30-$150 and pays for itself on the first few kilograms of stripped cable. If you’re regularly pulling out house wiring on renovations, the investment is straightforward.
Can I sell copper on behalf of my employer or company?
Yes. Bring your personal photo ID and documentation showing your company (business card, ABN document, or company letterhead). The transaction is recorded in the company’s name along with your ID. Many trades businesses set up regular accounts at preferred yards for exactly this reason.
What about old transformers and motors from electrical work?
Both are worth scrapping. Electric motors and transformers contain copper windings and are accepted at most Perth yards as a mixed commodity. They’re priced on the copper content (estimated by the yard based on the type and condition). They don’t need to be disassembled , bring them in whole.
Does the price change between grades of insulated cable?
Yes. Standard house wiring (TPS, single-core) pays better than heavy armoured cable or data cable because the copper-to-insulation ratio is higher. The yard will assess each type separately. Always ask what each grade is paying rather than assuming one price covers everything you’ve brought in.
Bottom line for Perth sparks
Copper wire scrap is one of the better side earners available to Perth electricians , and it’s already in your van at the end of every job. The only thing standing between you and a significantly better payout is a few minutes of sorting and a wire stripper tool you probably already have.
Set up two buckets, strip the TPS, keep the aluminium separate. That’s the whole system. The result is a meaningfully higher payment every time you come in.
