If you've spent fifteen years building a commercial cleaning business from the ground up — winning contracts, managing rosters at 11pm, navigating employment disputes, keeping on top of visa compliance — you've earned the right to exit on your own terms. But most owners who reach that point don't fully understand what their business is worth, or why the process of selling a cleaning business in New Zealand is materially different from selling almost any other kind of SME.
This guide is written for owners ready to think seriously about that next chapter. It will tell you what buyers actually look for, how your business is likely to be valued, and what the legal landscape — particularly Part 6A of the Employment Relations Act — means for how any sale gets structured.
Why Commercial Cleaning Businesses Are More Valuable Than Owners Think
The most common mistake owners make when estimating what their cleaning business is worth is leading with margin. At 15–17% EBIT, the instinct is to assume buyers will discount heavily. They don't — not if the contracts are solid.
What buyers are actually pricing is recurring contracted revenue. A commercial cleaning business with a well-diversified portfolio of multi-year contracts — property managers, DHBs, government agencies, schools, corporate tenants — generates the kind of predictable, month-on-month revenue that most industries can't replicate. You're not selling widgets. You're selling a contract stack with measurable retention history.
The post-COVID period permanently raised the floor on commercial hygiene standards. Facilities managers who might have reduced cleaning frequencies before 2020 are now locked into baseline service levels that are unlikely to reverse. That structural shift has made cleaning contracts more defensible, not less.
Client stickiness in this sector is also routinely underestimated. Commercial property managers, hospital networks, schools, and local government bodies do not switch cleaning providers lightly. Mobilisation costs are high, disruption risk is real, and established relationships with supervisors and site staff create genuine switching friction.
The market structure reinforces buyer appetite. At the top end, OCS, ISS, and Spotless dominate. Below that, the $2M–$10M owner-operated segment is fragmented and largely ignored by informed capital. That gap creates real consolidation opportunity — and for buyers who understand the sector, a well-run mid-market cleaning business represents a scarce asset.
Part 6A — The Employment Rule That Shapes Every Cleaning Business Sale
This is the section most owners wish someone had explained to them three years earlier.
Part 6A of the Employment Relations Act 2000 applies specifically to "cleaning or food catering services." When a cleaning business or a cleaning contract is sold, assigned, or transferred — or when a client moves their cleaning contract from one provider to another — the affected employees have a protected right to transfer to the incoming employer on no less favourable terms and conditions than their current employment agreement provides.
This is not a standard asset-sale employment clause. It's a statutory right that applies regardless of what the sale agreement says. It affects both the sale of the business itself and the transfer of individual client contracts.
What this means practically: a buyer cannot simply absorb your staff into a generic employment template on completion. They are legally required to honour existing terms — pay rates, hours, conditions — for the affected employees. Any buyer who doesn't understand Part 6A will either get caught in due diligence when their lawyers flag the liability, or — worse — proceed and face an Employment Relations Authority claim post-settlement.
For you as the seller, the implication is clear: your employment documentation needs to be in order before you go to market. Every employee needs a current written employment agreement. Hours and rates need to be accurately reflected. Sellers who don't have this documentation in order create their own surprises — and surprises in due diligence kill deals or crater price.
What Buyers Actually Look For in a Cleaning Business
Beyond the financials, professional buyers will work through a consistent checklist.
Written contracts with documented renewal history. Verbal arrangements with longstanding clients are a discount factor. Buyers need to see contract term, value, and renewal clause in writing. A client relationship you've held for eight years is worth significantly less if it's undocumented.
Client diversification. No single client should represent more than 20–25% of revenue. Concentration risk is one of the first things flagged in any quality of earnings analysis.
Living Wage Aotearoa NZ certification. An increasing number of government agencies, universities, and large corporates require their cleaning contractors to hold Living Wage Employer certification. If you've obtained this, it's a revenue quality signal — it tells buyers you're eligible for a category of premium public sector contracts that uncertified competitors can't access.
Management depth. Can the business run without you for a month? If your operations manager and supervisors can handle day-to-day operations without escalating to you, the business is materially less risky to acquire.
Job management and rostering systems. Deputy, Tanda, and similar platforms are now table stakes for a well-run cleaning business. Documented shift records, GPS check-ins, and digital timesheets serve two purposes: operational efficiency and compliance evidence.
ACC claims history. The cleaning sector carries above-average ACC levies. An employer with a clean claims record over several years demonstrates lower injury rates and a lower levy trajectory forward — which directly saves a buyer money. Document this clearly.
BSCNZ accreditation. Building Service Contractors NZ membership and accreditation is a credibility marker that professional buyers recognise.
Visa and work authorisation compliance. Any irregularity — expired visas, undocumented work rights — is a disclosed liability in due diligence. Resolve these before going to market.
How Cleaning and Facilities Management Businesses Are Valued in NZ
The standard valuation methodology is an EBIT multiple, typically ranging from 3x to 5x for well-documented businesses in the $2M–$10M revenue range. The multiple you attract depends almost entirely on revenue quality and documentation quality, not margin percentage in isolation.
The revenue quality hierarchy matters: government and hospital contracts attract the highest multiples because they carry low churn risk. Corporate office contracts sit in the middle. Retail and residential cleaning sits lower.
A business generating 15–17% EBIT from a diversified portfolio of written, multi-year public sector contracts can attract the same multiple — or better — than a business generating 25% EBIT from a concentrated, verbally-contracted client base. Buyers are not just buying last year's profit. They're buying forward earnings certainty.
Key discount factors: owner dependency, verbal or undocumented contracts, visa workforce irregularities, and undocumented Part 6A employment registers.
Owner remuneration normalisation is also critical. If you're paying yourself above market rate or running personal expenses through the business, a buyer's adviser will adjust EBIT accordingly. Make sure your accounts reflect market-rate remuneration before any valuation is commissioned.
Buyer Types — and Why Permanent Ownership Matters for a People-Heavy Business
Not all buyers are equal, and for a business built on people, the type of acquirer matters more than almost any other factor.
Trade buyers will integrate your business into their existing operation. Your brand will likely be retired. Your supervisors will be absorbed into a larger entity's culture and management structure.
PE-backed buyers follow a 5–7 year resale horizon. Earn-outs in this model are often tied to staff retention metrics — difficult conditions to satisfy in a high-turnover, HR-intensive environment.
Permanent holding companies operate on a third model. Businesses like Lifco and Judges Scientific in Europe have held facilities management and service businesses permanently — not as platform investments awaiting exit, but as long-term operating subsidiaries with preserved management and culture. The businesses retain their identity. The people stay.
NZ owners now have access to this model through PermaTech. For a cleaning business — where the business is its people, and where client relationships are held by supervisors and site managers as much as by the owner — an acquirer whose model depends on staff retention and cultural continuity is structurally aligned with what most sellers actually want. This isn't marketing. It's a structural fact about how permanent holding companies work, and it matters more in a people-heavy service business than almost anywhere else.
Preparing to Sell — A Practical Checklist
If you're planning to exit in two to three years, start on this list now.
- Three years of clean financials, with owner salary normalised to a market-rate management equivalent
- All client contracts documented in writing — term, value, renewal clause, service scope
- Part 6A employment register current — written employment agreements for every employee, hours and rates accurately reflected
- Visa and work authorisation compliance audit completed — resolve irregularities before going to market
- BSCNZ accreditation current
- ACC claims history documented — a clean record is a demonstrable asset
- Living Wage Aotearoa NZ certification obtained if you hold government, hospital, or university contracts
- Key supervisors on formal written employment contracts with notice periods
- Job management and rostering system implemented (Deputy, Tanda, or similar)
- Independent business valuation commissioned before engaging any buyer
Most cleaning business owners who sell well say the same thing in hindsight: they wished they'd started preparing earlier — not because the market wasn't there, but because preparation turned a reasonable outcome into a genuinely good one.
If you're ready to have a confidential, no-obligation conversation about what your business is worth and what a sale could look like for you and your team, PermaTech is happy to start that conversation directly — no broker, no pressure, no process until you're ready for one.
