How Much Is a Fire Protection Business Worth in Australia?

Fire protection is one of those industries that most business buyers overlook — until they start looking at the numbers. You've got legal compliance driving recurring revenue, a fragmented market full of retiring owner-operators, and a licensing framework that creates genuine barriers to entry. For a buyer in the $500K to $3M range, it can be an interesting place to look.

But how much does a fire protection business actually sell for in Australia? The honest answer is: it depends heavily on one thing, and most buyers don't ask about it until they're three weeks into due diligence.

What a "fire protection business" actually means

Before you can value one, you need to know what you're buying. Fire protection businesses in Australia cover a wide range of work:

Annual compliance inspections (fire extinguisher servicing, hose reels, emergency lighting, exit signs)
Installation of suppression systems (sprinklers, kitchen suppression, special hazard)
Fire detection and alarm systems
Passive fire protection (fire doors, penetration sealing)
Service and maintenance contracts for all of the above

The mix matters enormously. A business that's 80% compliance servicing — think annual inspections under AS 1851 — operates completely differently to one that's 80% installation. Same industry, very different investment proposition.

EBITDA multiples: what buyers are actually paying

Small fire protection businesses in Australia — EBITDA under $500K — typically trade at 2.5x to 4.5x EBITDA. Businesses in the $500K to $2M EBITDA range can push to 4x to 6x, particularly if they have strong recurring contracts and documented systems.

Those are wide ranges, and the spread is intentional. A business at the high end of that range looks nothing like one at the low end. The single biggest driver of where you land is the proportion of revenue that comes from recurring maintenance contracts versus one-off installation work.

This is covered in more depth in EBITDA multiples for trades businesses, but for fire protection the principle is stark: installation revenue is project-based, lumpy, and depends heavily on the owner's relationships. Maintenance contract revenue is recurring, legally mandated (occupants have to comply with AS 1851 whether they feel like it or not), and transfers with the business.

A fire protection business that's 70% maintenance contracts on a 3-year renewal cycle is worth considerably more than the same EBITDA delivered through one-off jobs. The market knows this, and prices accordingly.

Why recurring revenue changes everything for valuation

Annual fire compliance inspections in Australia are legally required. Building owners and strata managers don't call their fire protection company because they feel like it — they call because their insurer or council requires it and their building manager has it on a compliance calendar. That's about as close to guaranteed revenue as you'll find in a trades business.

For a buyer, this changes the risk profile fundamentally. You're not acquiring a sales pipeline that could evaporate if the previous owner stops schmoozing — you're acquiring a compliance obligation book. Buildings don't stop needing inspections. (They occasionally burn down, but that's actually good for the installation side of the business, which is perhaps the only industry where that sentence doesn't sound horrible.)

When evaluating a fire protection business, the first question I'd ask is: what percentage of last year's revenue came from contracts that have already auto-renewed or are on multi-year agreements? A business with 65% of revenue locked in recurring maintenance, with average contract tenure of 5+ years, justifies the higher end of that multiple range. A business where the owner does the annual rounds personally and has a handshake arrangement with most clients justifies a significant discount — not because the revenue isn't real, but because it's owner-dependent in the worst possible way.

The recurring revenue assessment framework applies directly here.

The licence risk nobody talks about

Here's the thing that catches buyers out: in most states, fire protection work requires a licensed tradesperson — and the licence is individual, not transferable to the business.

In Queensland, Victoria, and most other states, fire protection technicians need specific licences to perform AS 1851 inspections and certain installation work. If the previous owner holds those licences personally, and leaves the business at settlement, you may be legally unable to perform the work that generates 70% of your revenue.

I spoke to a business broker last year about a deal that fell apart — not on price, not on financing, but because the buyer's solicitor identified that the key technician and licence holder was the owner's son, who was planning to go interstate. The business had $800K in recurring maintenance contracts. Without the licensed tech, it was worth significantly less. The deal restructured around a 12-month employment arrangement for the son, but it added complexity and cost that nobody had budgeted for.

Before you place serious value on a fire protection business, map every licensed technician on the team — who holds what licence, in which state, and what their employment plans are. Then model what revenue you could legally perform without each of them. That stress test tells you more than any multiple.

Key valuation drivers — what pushes the price up or down

Factors that support a higher multiple:

Long-term maintenance contracts with automatic renewal clauses and fixed annual price escalation
Diversified client base — no single client contributing more than 10-15% of revenue
Multiple licensed technicians across relevant licence categories
BMS (Building Management System) access or preferred supplier status with property managers
Clean AS 1851 compliance records — no outstanding notices or near-misses
Documented service procedures that don't rely on a single person's knowledge

Factors that discount the price:

Revenue concentration in installation projects (volatile, non-recurring)
Owner holds the primary contractor licence and manages all client relationships personally
Geographic concentration — all clients in one suburb or one building precinct
Ageing equipment inventory with pending capital expenditure
Mix of residential and commercial work (commercial-only businesses command higher multiples)
State-by-state licence gaps if you want to expand

How to run the numbers yourself

Start with the EBITDA the seller is claiming. Then normalise for add-backs — owner's salary above market replacement cost, personal vehicle, phone, travel, any non-arm's-length expenses running through the business. For a $2M revenue fire protection business, it's not unusual to find $80K-$120K in legitimate add-backs, which meaningfully changes the EBITDA base.

Once you have a normalised EBITDA, apply a multiple based on the factors above. A 3x multiple on $300K normalised EBITDA gives you a $900K enterprise value. Add back net working capital (if the business delivers it above a peg), subtract any debt assumed, and you have your equity value.

Cross-check against a revenue multiple as a sanity test. Fire protection businesses typically trade at 0.5x to 1.2x annual revenue, depending on the maintenance/installation split. If a business is doing $1.5M revenue and the EBITDA-based valuation gives you $1.8M, that implies a 1.2x revenue multiple — which is at the top end and only justified if the contracts are airtight.

This is how to value a small business in Australia — the underlying principles don't change, but the specific multiples and risk factors are industry-dependent.

What the market looks like right now

The Australian fire protection services industry generates around $4.2 billion in annual revenue across roughly 2,900 businesses. The majority are small operators — 2-10 technicians, owner-operated, doing compliance servicing in a defined geographic patch.

Many of these owners are in their 50s and 60s. They built the book of maintenance contracts over decades. They're not rushing to sell, but they're also not planning to expand. The off-market approach — a direct letter or a phone call through an industry contact — often works better than going through a broker, because these owners haven't thought seriously about selling and don't want to advertise.

If you're looking at the sector, check the industry multiples cheat sheet — it includes fire protection alongside other trades service businesses.

A worked example

A Melbourne-based fire protection business I looked at recently had the following characteristics:

$1.8M annual revenue, split 68% maintenance / 32% installation
Normalised EBITDA of $380K (after adding back owner salary excess and personal vehicle)
340 active maintenance contracts, average 4.2 years on the books
Three licensed technicians (one was the owner, two were employees intending to stay)
No client above 8% of revenue
Operated from a leased workshop with 4 years remaining on the lease

At 4x EBITDA, that's a $1.52M business. At 4.5x (justified given contract quality and technician retention), it's $1.71M. The asking price was $1.65M — comfortably within range. The real negotiation was around the working capital peg, not the headline multiple.

That's a fairly typical scenario for a well-run compliance-heavy fire protection business in a major metro. Regional businesses trade at similar EBITDA multiples but often require the buyer to obtain licences in adjacent shires, which is worth factoring into your integration plan.

Frequently asked questions

What EBITDA multiple should I pay for a fire protection business in Australia?

For a small business with mostly recurring maintenance revenue, 3x to 4.5x EBITDA is a reasonable range. Businesses with particularly strong contract books, multiple licensed techs, and no key-person risk can justify up to 5x or slightly above.

Is installation revenue worth less than maintenance revenue?

Yes, significantly so. Installation revenue is project-based and often tied to the owner's relationships and licence. Maintenance revenue is recurring and compliance-driven. Buyers price this difference into the multiple.

Does the business need to come with licensed technicians?

It depends on the work performed. For businesses doing AS 1851 compliance work, you need licensed technicians to legally perform the work. If the owner is the only licence holder and intends to leave, that is a material deal risk that should affect both price and structure.

What's a typical profit margin for a fire protection business?

EBITDA margins for compliance-focused fire protection businesses typically run 18-28%. Installation-heavy businesses often show higher revenue but lower margins because of materials costs and subcontractor labour.

Can I buy a fire protection business without industry experience?

Yes, but you'll need a plan for the licence requirements. Most buyers in this space hire the licensed technicians as part of the acquisition and focus their attention on the business management, customer relationships, and admin. The operational side can be run with the right team.

Where to go from here

If you're building a shortlist of trades businesses to evaluate, fire protection is worth putting on it — the recurring compliance revenue dynamic is genuinely good for a first-time buyer, and the market fragmentation means deals are available without fighting over them at auction.

The framework for evaluating any acquisition starts in Module 4 of the Playbook, which covers how to value a business before you've signed anything.
