Due Diligence When Buying an Electrical Business in Australia

Due diligence when buying an electrical business in Australia means verifying electrical contractor licences, reviewing three years of financials, assessing tools and vehicles, checking the licensing structure of staff, and confirming there are no outstanding compliance notices or WHS breaches before you sign anything.

Electrical businesses carry some of the most specialised compliance obligations of any trades category. The risk isn't just commercial — it's regulatory. If the person holding the contractor licence leaves on settlement day, you may not be able to legally trade until you sort out a replacement. That's not a hypothetical. It happens.

This article walks through the full due diligence process for buying an electrical business in Australia — what to check, what documents to request, and where the traps tend to hide. This sits within Module 5 of the Playbook, which covers the full due diligence framework for business buyers.

Why Electrical Businesses Need Specific Due Diligence

Most small business due diligence follows a standard pattern — financial review, asset assessment, contracts, staff. Electrical businesses need all of that, plus a layer of licence verification that most buyers aren't used to.

In Australia, each state has its own licensing regime for electrical contractors and electricians. The licence holder is typically the business owner. When you buy the business, that licence doesn't transfer to you automatically. In most states, you need to hold a relevant licence yourself, employ someone who does, or apply for a contractor licence before you can trade.

A broker told me about a deal last year where the buyer settled on an electrical business without realising the sole licensed contractor was the retiring owner. The buyer spent three months scrambling to find a licensed tradesperson to put on the contractor licence — during which time they couldn't legally quote on new work. Revenue dropped 40% in that period.

Before you get excited about the numbers, check the licence situation first.

Step 1: Licence and Registration Verification

The first thing to confirm is who holds the electrical contractor licence, what it covers, and whether it's current.

Electrical contractor licences in Australia are state-based:

NSW: Fair Trading (electrical contractor licence)
Victoria: Energy Safe Victoria (electrical contractor licence and restricted electrical licence)
Queensland: QBCC (electrical contractor licence under the Electrical Safety Act)
WA: EnergySafety (electrical contractor licence)
SA: Consumer and Business Services
Tasmania: WorkSafe Tasmania
ACT: Access Canberra
NT: NT WorkSafe

You can verify licences directly on each regulator's public register. Don't rely on the vendor showing you a copy — check it yourself.

Beyond the contractor licence, also verify:

Individual electrician licences for each employee who holds one (each state has a registration for electricians — you want current, not lapsed)
Restricted licences for any staff doing specialised work (switchboard upgrades, high-voltage, air conditioning circuits)
QBCC licence if the business operates in Queensland and does any building work alongside electrical
Any certifications specific to the work (data and communications cabling, solar installation, mine-site electrical)

For the licences and permits due diligence specifically — electrical is one of the categories where a lapsed licence is a hard stop, not just a price chip.

Step 2: Financial Review

Request three full financial years plus the most recent management accounts. For an electrical business, you're specifically looking at:

Revenue quality: Is revenue from commercial contracts, residential service work, or new builds? Residential service (maintenance, fault finding, upgrades) is stickier than new construction — if a developer relationship ends, so does a chunk of revenue.

Labour margins: Labour is the dominant cost in electrical businesses. Compare gross margin against industry benchmarks — the ATO benchmark for electrical contractors sits between 37% and 47% gross margin. Anything materially below that warrants explanation.

BAS reconciliation: Cross-reference the BAS lodgements with the profit and loss statements. Electrical businesses are heavily cash-friendly at the residential end — some owners work on an informal understanding with certain customers. If BAS reported revenue is consistently lower than bank deposits, ask questions.

Work in progress: Electrical businesses often have jobs partially complete at any given time. If there's significant unbilled WIP, how has it been valued? And have the quoted prices been checked against actual costs to complete — especially on fixed-price contracts?

Add-backs: Common add-backs in electrical businesses include owner's wages, personal vehicles run through the business, and tools purchased that are actually personal items. Verify each one. See the EBITDA add-backs article for the full framework.

One rule of thumb: a well-run electrical business with recurring commercial clients and a stable team should produce seller's discretionary earnings of 20-28% of revenue. If you're seeing lower margins, ask whether labour is being priced correctly or whether the owner is doing unpaid overtime that won't be there once you settle.

Step 3: Licensing Pyramid — Staff Structure

This is where electrical due diligence gets genuinely complicated. The staff structure in an electrical business determines whether the business can operate at all after you take over.

In most states, you need a licensed electrical contractor to supervise the work of apprentices and unlicensed workers. The ratio of licensed electricians to apprentices is regulated (typically 1:1 or 1:2 depending on the state).

When you're reviewing the staff list, categorise each person:

Licensed contractor (can run a job independently)
Licensed electrician (qualified tradesperson, can be supervised by contractor)
Apprentice (limited work without supervision, ratio-restricted)
Office or admin staff

Then ask: if the current owner walks out on settlement day, who's left to carry the contractor licence? If the answer is nobody, that's either a deal-breaker or a heavy price chip.

Some buyers deal with this by requiring the vendor to stay on for six to twelve months on a paid consulting arrangement while the buyer obtains their own licence or recruits a licensed contractor. That's worth building into the heads of agreement.

The employee entitlements due diligence process still applies here — check annual leave balances, whether apprentices are being paid correctly under the relevant award, and whether any staff have untaken long service leave on the books.

Step 4: Plant and Equipment

Electrical businesses are more vehicle-heavy than some trades and less so than others. The key assets to assess are:

Vehicles: A service-based electrical business typically runs a van or ute per electrician. Condition, age, maintenance history, and whether they're owned outright or financed. Check rego and PPSR for any security interests on financed vehicles.

Test and measurement equipment: Multimeters, clamp meters, insulation testers, RCD testers, thermal imaging cameras (for commercial switchboard work). This equipment depreciates quickly and gets beaten up on site. Some of it may be past its calibration date — if it's been used for compliance testing, this matters.

Power tools and hand tools: Less of a valuation driver, but tool inventory is often padded out in information memoranda. Do a physical count against the asset list.

Stock on hand: Electrical consumables — cable, conduit, fixings, switchboard components. If there's a significant stock holding, have it independently valued. Outdated or superseded parts aren't worth face value.

See the plant and equipment due diligence framework for the full process.

Step 5: WHS and Compliance Obligations

Electrical work sits at the high-risk end of the WHS spectrum. Live electrical systems, working at heights, confined spaces — the obligations are real.

What to check:

WHS management system: Does the business have documented Safe Work Method Statements (SWMS) for high-risk work? In most states, a SWMS is legally required before commencing high-risk electrical work. If the current owner has been doing this informally, you inherit the risk of any past non-compliance.

Incident and near-miss register: Ask for the last three years of WHS incident records. A nil return from a business that does live electrical work is either impeccably safe or hasn't been keeping proper records.

Outstanding compliance notices: Check with the relevant regulator (Energy Safe Victoria, QBCC, Energy Safety WA, etc.) for any notices, infringements, or investigations on the business name or contractor licence. A notice the vendor hasn't disclosed is a serious red flag.

Public liability insurance: Minimum $10 million PLI is standard. Check the expiry and claims history. An electrician who's had a claim for faulty workmanship will have a premium history that tells its own story.

The WHS due diligence for trades businesses article covers the full framework including what documents to request.

Step 6: Customer Base and Contracts

Electrical businesses vary enormously in how their revenue is structured. Some run on word-of-mouth residential work; others hold commercial maintenance contracts with body corporates, property managers, or industrial clients.

For each revenue stream, understand:

Whether there's a written contract or just a verbal arrangement
What the notice period for termination is (if there's a contract)
Whether the contract is transferable to a new owner (many commercial contracts have change-of-control clauses)
How much of revenue comes from the top three clients (the customer concentration risk article covers what levels are acceptable)

A body corporate maintenance contract might look like a recurring revenue gem until you read the clause that says it terminates automatically on change of ownership. Happens more than you'd think (the lawyers who draft these contracts get paid regardless of the outcome).

Step 7: Intellectual Property and Systems

For most electrical businesses, the IP isn't sophisticated — but there are a few things to check:

Quoting software and templates: If the business uses custom quoting software or detailed templates, confirm who owns them. If they were built with a contractor, the IP might not be in the business's name.

Customer list and CRM: The customer database is one of the most valuable assets in a service business. Confirm it's owned by the business (not the owner personally) and will transfer cleanly.

Brand: Is the business trading under a registered business name or a company name? Confirm the name transfers as part of the sale.

What Good DD Looks Like in Practice

A thorough due diligence process for an electrical business typically takes four to six weeks and involves:

Your accountant reviewing three years of financials and tax returns
Your lawyer reviewing the SPA, any commercial contracts, the lease, employment agreements, and any assets being transferred
You personally reviewing licence registers, the staff structure, WHS documentation, and doing a physical inspection of tools and vehicles
An independent valuation of any significant plant if the deal price relies on asset values

FAQ

What licences do I need to buy an electrical business in Australia?

You generally need to hold an electrical contractor licence yourself, or employ someone who does, to legally trade as an electrical business. Licence requirements vary by state — check with your state's electrical safety regulator before signing anything.

Can I buy an electrical business without being a licensed electrician?

Yes — many buyers are not tradespeople. But you'll need a licensed electrical contractor on staff or as a director to hold the contractor licence. Without that, you can't legally supervise electrical work or quote on jobs.

How long does due diligence take for an electrical business?

Typically four to six weeks for a thorough process — assuming the vendor provides documents promptly. Add a week if you're verifying licences across multiple states or if the business has commercial contracts that need review.

What financial documents should I request when buying an electrical business?

Request three years of tax returns, profit and loss statements, balance sheets, BAS lodgements, and the most recent management accounts. Also request an aged debtors list and any outstanding WIP schedule.

What's the biggest due diligence risk in electrical businesses?

Licensing structure — specifically who holds the contractor licence and what happens to that licence after settlement. This is the issue most buyers don't check carefully enough, and it's the one most likely to stop you trading on day one.
