Winning Subcontract Work
Subcontracting to builders and larger trade businesses is a work channel with almost no sales cost and its own set of risks. Here's who's actually hiring, how to get on their list, and what it should be worth to you.
Every trade business needs more than one way of getting work, and subcontracting is one of the few channels where the work comes to you in volume without you paying for a lead. Builders, larger trade businesses, facilities managers and insurance networks all need reliable trades they can call, and most of them are short of them. It's not free money — the margin is thinner, the payment terms are longer, and leaning on it too hard makes you someone else's capacity rather than your own business. This guide covers who to approach, what they're actually buying, how to get on the list and stay there, and how to price it so it's worth having.

Who actually engages subbies
"Subcontracting" gets talked about as though it means one thing. In practice there are half a dozen quite different buyers, and they want different things from you:
| Who | What they're after |
|---|---|
| Builders and head contractors | Trades who hit the program, don't create defects and don't need chasing for paperwork |
| Larger businesses in your own trade | Overflow capacity when they're booked out. Often the easiest first door, because they already know your trade |
| Facilities and property managers | Reactive maintenance across a portfolio — response times and reporting matter more than price |
| Strata and real estate agencies | Small reactive jobs, lots of them, with tenants and owners in the middle |
| Insurance and repair networks | Make-safe and repair work to defined scopes, with heavy reporting requirements and set rates |
| Retail and product installers | Installation work behind someone else's sale — solar, appliances, HVAC, security |
| Government and commercial panels | Formal panel arrangements. Slow to get on, steady once you are |
Pick two or three that suit the work you actually want. Chasing all of them at once means being unimpressive to everyone, and the reporting demands of an insurance network are a different business from doing fit-off for a builder.
What they're actually buying
New subbies assume the pitch is quality and price. It isn't. Anyone hiring a subbie has been let down before, and what they're buying is the absence of that. In rough order:
- You turn up when you said. More work is lost over a missed Tuesday than over a rate.
- You answer your phone. The subbie who picks up gets the next job. This is not complicated and it is remarkably rare.
- Your paperwork arrives complete. Certificates, SWMS, photos, invoices with the right job reference. Every gap is admin work you've handed to them.
- You don't create problems for the trades after you. The bloke who leaves it right for the next trade gets remembered by everyone on that site.
- You raise issues early. A problem flagged Wednesday is manageable. The same problem discovered at handover is a fight.
- No safety incidents and no cowboy behaviour — because your conduct on their site lands on their record.
Price matters, but it's the filter rather than the decision. Being the cheapest gets you a first job and a reputation as the cheap option; being the reliable one gets you the phone call before anyone else is asked.
Getting on the list
- Make a target list of twenty. Builders and businesses operating in your area, at your scale. Drive past sites and read the signage. Ten realistic targets beats a mass email to a hundred.
- Get your compliance pack together first. Licence, certificate of currency for public liability, injury cover, ABN and entity details, tickets, SWMS templates, and a page of relevant jobs with photos. Having it ready when they ask is itself the demonstration.
- Find the right person. The site supervisor, the contracts administrator, or the owner — not the info@ address. On a smaller builder it's whoever answers, and one direct conversation beats twenty emails.
- Approach at the right moment. Early in a week, not at 4pm Friday. And be specific: what you do, where you work, what you can take on, when you're available. Vague availability reads as no availability.
- Take the awkward first job. The fill-in, the one someone dropped, the small job nobody wants. That's the audition, and doing it excellently is the entire strategy.
- Ask for the next one. Directly, on the day you finish. "That went well — what have you got coming up?" Most tradies never ask, then wonder why the phone didn't ring.
Your existing network is the shortest path in. Suppliers know who's busy and who's short-handed, and other trades on your current sites are working for builders you haven't met. Ask the sparkie you shared a site with last month who's worth working for — you'll get an honest answer and often an introduction.
What keeps you on the list
Winning the first job is the easy part. Businesses that build a steady subcontract book do the unglamorous things consistently:
- Prequalification kept current. When your certificate of currency expires, you come off the system — often without anyone telling you.
- SWMS and safety documents per job, submitted before you start, not chased out of you on the morning.
- Photos and completion records attached to the job. For maintenance and insurance work this is most of what you're being paid for.
- Invoices that match the agreed scope and reference their job number. Sloppy claims are the most common reason a good subbie gets quietly dropped.
- Variations raised in writing before you do the work, every time. Doing extra work on a nod and billing for it later damages the relationship even when you're right.
- Predictable capacity. Being honest that you can't take something this week keeps you on the list. Saying yes and letting them down does not.
Pricing it so it's worth having
Subcontract rates sit below what you'd charge a homeowner for the same hour, and that's not necessarily a bad deal — you're not paying to generate the lead, not quoting five jobs to win one, and not managing the client. But it only works if you know your own numbers going in.
- Know your break-even rate first. Our charge-out rate guide works it out from your overheads and genuinely chargeable hours. A subcontract rate below break-even is a job you're paying to do.
- Count the real chargeable proportion. Site inductions, waiting on other trades, travel between sites and the reporting all eat hours you can't bill.
- Price the paperwork. Insurance and facilities work carries reporting that can take as long as some of the jobs. Build it into the rate rather than discovering it in month two.
- Read the payment terms before the rate. Long terms are a real cost to a small business, and they're often more negotiable than the rate is.
- Watch for retention and back-charges. Money held until a defects period ends, or deducted for someone else's damage, changes what the job actually pays.
- Understand what's included. Materials, plant, access equipment, waste removal and making good are frequently assumed by one party and priced by neither.
Track subcontract jobs separately from your direct work so you can see what each channel actually returns per hour. Plenty of trade businesses discover the subcontract work they thought was carrying them is being subsidised by their domestic jobs.
The risks worth naming
- Concentration. When one head contractor is most of your revenue, you don't have a customer — you have an employer who can end it without notice and owes you nothing.
- Payment risk. If they don't get paid, you'll feel it. Know who you're contracting with, watch how they pay from the first invoice, and take a slow payer seriously the first time rather than the third.
- You become the flexible one. When the program slips, someone absorbs it. Make sure the agreement says who.
- Your own work gets squeezed. Subcontract work is easy to say yes to and slowly crowds out the direct clients who pay better and are yours to keep. Book your own jobs first and fill the gaps.
- Classification. A long-running arrangement where you work only for one business, on their roster, in their gear can stop looking like contracting. Our guide on subcontractor or employee covers what that turns on and why it matters.
ServiceYak keeps both sides of the book in one place — your own jobs and your subcontract work on the same schedule, with time and materials logged against each job — so you can see which channel is actually making money instead of assuming the busy one is.
Frequently asked questions
How do I find subcontract work as a trade business?
Make a target list of builders and larger trade businesses operating at your scale in your area, get your compliance pack ready before you approach, and go to the person who books trades rather than a general enquiry inbox. Your existing network is the fastest route — suppliers and other trades on your current sites know who's short-handed and will usually introduce you.
What should I charge for subcontract work?
Start from your own break-even rate — overheads plus the income you need, divided by your genuinely chargeable hours — then decide what margin the reduced sales cost justifies giving up. Take off the hours lost to inductions, waiting on other trades and reporting, and read the payment terms before you agree the rate, because long terms are a real cost that's often more negotiable than the number.
How much of my work should come from subcontracting?
Enough to smooth out the quiet weeks, not so much that one head contractor can take your business away. If a single client is a large share of your revenue, treat that as a risk to actively manage — keep quoting direct work and book it in first, then fill the gaps with subcontract jobs.
What paperwork do builders expect from a subbie?
A current trade licence, a certificate of currency for public liability, evidence of injury cover, your ABN and entity details, the tickets the work requires, and a SWMS for high-risk work submitted before you start. Keep the expiry dates diarised — coming off a builder's approved list because a certificate lapsed is a common and entirely avoidable way to lose steady work.
