A cleaning business built on reliable recurring contracts, stable staff and organised compliance records can be a highly attractive acquisition. One built on handshake arrangements, informal subcontractors and an owner who personally manages every client is a much harder sell. This guide explains the difference — and how to make sure yours is the former.

What makes selling a cleaning business different?
Most businesses are valued primarily on profit. Cleaning businesses are valued on something more specific:recurring revenue and contract transferability.
A buyer is not just buying the profit from last year. They are buying the right to collect that profit again next month, and the month after. That depends on:
Whether clients are on contracts — and whether those contracts can transfer to a new owner
Whether staff are reliable and willing to stay post-sale
Whether the operational systems (schedules, route planning, keyholding, COSHH management) are documented well enough that the buyer can run the business without the seller
Whether the margins are real — after travel, consumables, staff costs and management time
Buyers will also scrutinise owner dependency hard. If the seller personally visits every client, handles every complaint and knows every access code from memory, that is not a transferable business — it is a job. A buyer paying goodwill needs confidence the revenue will continue without the seller.
Commercial cleaning businesses — serving offices, schools, healthcare facilities, retail and industrial clients — are generally more attractive to buyers than domestic cleaning operations, because commercial contracts tend to be written, monthly-billed and less personally dependent on the individual cleaner. That said, well-run domestic cleaning businesses with documented customer relationships, formal terms and a stable cleaner team can also sell well.
When is the best time to sell?
The best time to sell is when the business presents the strongest evidence of sustainable recurring income.
Sell when:
Contracts are stable and written— clients on formal agreements are far more attractive than those on informal or verbal terms
Client retention is high— a low churn rate over two or more years tells a buyer the revenue is reliable
Staff are reliable and employed on proper contracts— a stable cleaning team reduces key-person risk
Margins are clear and documented— route density, product costs and subcontractor margins are all calculable
Equipment and vehicles are maintained— a buyer does not want to inherit immediate capital expenditure
COSHH records are organised— this is a basic health and safety requirement, and gaps raise red flags
Owner dependency is reduced— the fewer decisions that funnel through the seller personally, the better
Consider preparing before marketing if:
Most clients are on verbal arrangements that could be cancelled at short notice
Staff turnover has been high in the past twelve months
Subcontractors are used without written agreements or confirmed insurance
Pricing is inconsistent across similar jobs
Keyholding is informal and undocumented
COSHH assessments are out of date or missing
A single client accounts for more than 25–30% of revenue
The seller personally manages every client relationship
If you are in the second category, six to twelve months of preparation — formalising contracts, documenting procedures, reducing owner dependency — can meaningfully increase the sale price.
How much is a cleaning business worth?
Cleaning businesses are valued primarily onmaintainable profit, weighted heavily by the quality of recurring revenue.
The starting point: adjusted EBITDA
Adjusted EBITDA (earnings before interest, tax, depreciation and amortisation) is calculated by removing one-off items and adjusting the owner's salary to a market-rate management equivalent. An add-back schedule should be prepared with your accountant before marketing.
What a buyer considers
From the adjusted profit figure, a buyer applies a multiple that reflects:
Contract quality— written contracts with meaningful notice periods attract a higher multiple than informal arrangements
Client concentration— a business with revenue spread across 50 clients is less risky than one where 3 clients represent 80% of income
Recurring versus one-off revenue— monthly recurring contracts are worth more than ad hoc or project-based work
Staff stability— a cleaning team with low turnover and proper contracts reduces operational risk
Gross margin— after direct labour, travel and consumables, what percentage of revenue becomes gross profit?
Route density— are jobs clustered geographically, reducing travel costs and increasing efficiency?
Owner dependency— how much of the management is genuinely delegated?
Equipment and vehicles— owned outright adds value; heavily financed assets reduce net value
What increases value
Written contracts with 30, 60 or 90-day notice periods
Commercial clients (offices, schools, healthcare, retail) on monthly recurring billing
Low client churn over two or more years
Stable staff employed on proper contracts
Documented cleaning schedules and site-specific risk assessments
Strong gross margin after direct costs
Good insurance record with no significant claims
Organised COSHH and keyholding documentation
Low or manageable owner dependency
A written handover plan
What reduces value
Verbal or informal client arrangements
High client churn or concentration in a few large clients
Staff instability or high reliance on subcontractors without written agreements
Unexplained margin variation between jobs
Heavy owner involvement in daily operations
Gaps in COSHH, health and safety or insurance records
Keyholding procedures that are informal or undocumented
Unclear pricing across the client base
What financial information should you prepare?
Prepare the following before marketing:
Three years of filed accounts— profit and loss, balance sheet
Current year management accounts— year to date, with comparison to the prior year
Revenue by client— showing each client's monthly and annual value
Revenue split: recurring vs one-off— what percentage is contracted and repeating?
Contract gross margin by client or category— revenue minus direct labour, travel and product cost
Subcontractor payments— totals, frequency and whether on formal agreements
Payroll records— staff numbers, hours, rates, pension, employer NI
Cleaning product and consumables costs— annual spend and as a percentage of revenue
Vehicle costs— fuel, insurance, servicing, finance payments
Equipment costs— depreciation or finance payments on machines
Insurance premiums and claims history
VAT returns— if registered, to cross-check turnover
Aged debtors— are any clients slow to pay?
Tax position— PAYE, VAT, corporation tax all current?
Add-back schedule— owner salary, owner vehicle, one-off items, non-recurring costs
Key metrics to know before any buyer meeting
Monthly recurring revenue (MRR)— the total contracted monthly income
Contract gross margin— after direct labour, travel and consumables
Staff cost as a percentage of revenue
Average client tenure— how long do clients stay?
Churn rate— how many clients have left in the past twelve months?
Revenue by top five clients— and what percentage they represent
Owner hours per week— and what function would need replacing if the owner left
Contracts and customers
This is the single most important commercial element of a cleaning business sale.
What to prepare
For each client, prepare a summary showing:
Client name (this can be withheld pre-NDA and shared as anonymised data)
Service type (commercial/domestic, frequency, specification)
Annual revenue
Start date
Contract status — written or verbal, and if written, the notice period
Payment history — any arrears or late payments
Assignment clause — can the contract transfer to a new owner without client consent?
Any complaints or service issues in the past twelve months
Commercial cleaning
Commercial clients — offices, schools, healthcare facilities, retail outlets, industrial units — tend to produce the most transferable recurring revenue. Buyers will look for:
Formal written service agreements (not just a quote and an email)
Notice periods of 30 days or more
Monthly invoicing with clean payment history
Site-specific risk assessments and COSHH datasheets
Low or zero complaint history
Clear specification for hours, frequency and tasks
Domestic cleaning
Domestic clients are more personally loyal to their cleaner than to the business. Buyers will be cautious about domestic books where:
Clients contact the cleaner directly, not the company
There are no written terms or cancellation provisions
Clients follow their favourite cleaner rather than staying with the brand
Routes are inefficient or spread across a wide geography
The owner personally cleans some clients
A domestic cleaning business can still sell well if it has good systems, documented client relationships, stable cleaners and a track record of client retention even when individual cleaners have moved on.
Client data and GDPR
Client names and contact details are personal data under UK GDPR. Do not share a raw client list before an NDA is in place. Share anonymised summaries in early discussions — number of clients, average monthly value, contract profile, churn rate. Full client details should only be shared during formal due diligence with appropriate data protection controls in place.
Staff, subcontractors and TUPE
Cleaning is a labour-intensive business. Staff and subcontractors are central to both the value and the risk of the sale.
Employed staff
Prepare:
Full staff list with roles, hours, pay rates and start dates
Written employment contracts for all staff
Holiday entitlement accrual and any outstanding liabilities
Pension auto-enrolment records
Right-to-work documentation
Training records — including COSHH, manual handling, lone working
DBS certificates where relevant (particularly for healthcare, schools or keyholding clients)
Disciplinary or grievance records
Keyholder assignments — which staff hold access to which client premises
Under TUPE (Transfer of Undertakings (Protection of Employment) Regulations 2006), employees connected to the business will normally transfer to the buyer on their existing terms and conditions. This applies to most cleaning business asset sales. Acas specifically identifies office cleaning as an example of a service where TUPE may apply.
Both seller and buyer must comply with TUPE information and consultation obligations. Failure to do so can result in compensation claims. Take employment law advice early.
Subcontractors
If the business uses self-employed subcontractors, buyers will examine this carefully.
Prepare:
List of all subcontractors with the clients or routes they cover
Written subcontractor agreements — including payment terms, notice periods and obligations
Evidence of subcontractor public liability insurance
UTR (Unique Taxpayer Reference) numbers and self-employment status evidence
Whether the subcontractor relationship could be challenged by HMRC as disguised employment
Whether subcontractors are likely to continue with the new owner
Subcontractors have no TUPE protection and can leave without obligation. A buyer relying on subcontractor-delivered revenue needs to factor in that risk.
COSHH, insurance and safety records
Cleaning involves chemicals, lone working, manual handling and access to client premises. Buyers — and their insurers — will expect proper records.
COSHH
The HSE's guidance on COSHH (Control of Substances Hazardous to Health) specifically addresses cleaning work. Prepare:
COSHH assessments for each product used, including concentrations and application methods
Safety data sheets for all cleaning chemicals
PPE policy — what PPE is provided, when it must be used, and how compliance is checked
Manual handling risk assessment
Ventilation and skin care guidance for staff
Training records showing staff have been trained on chemical use and PPE
Missing or outdated COSHH records are a common red flag in cleaning business due diligence. Buyers and their solicitors will ask for them.
Health and safety
Also prepare:
Health and safety policy (required if you have five or more employees)
Site-specific risk assessments for each client location
Lone working policy — how are staff contacted and what are the check-in procedures?
Accident book and records of any reported incidents
Slips, trips and falls controls (cleaning creates wet surfaces)
Manual handling records
Waste disposal arrangements
Keyholding
Access to client premises is one of the biggest trust-based risks in a cleaning business. Buyers will scrutinise keyholding carefully.
Prepare:
A keyholding register — which staff hold which keys, for which premises
Sign-in/sign-out procedures
What happens if a key is lost or a staff member leaves
Whether clients have been notified about keyholding arrangements
Insurance cover for key loss or premises liability arising from access
If keyholding is informal — keys handed out without records or proper procedures — this is a serious concern for buyers and can affect insurability.
Insurance
Prepare current certificates and renewal schedules for:
Public liability— minimum £5 million, often higher for commercial cleaning
Employers' liability— legally required for any business with employees
Professional indemnity— where relevant (e.g. specialist cleaning services)
Vehicle insurance— business use cover for all company or staff vehicles
Equipment insurance— if relevant
Key insurance— cover for key loss or premises liability arising from keyholding
Claims history— any claims in the past five years, including settled and declined
Equipment, vehicles and systems
Equipment
Prepare a list of all cleaning equipment, including:
Industrial vacuums
Commercial floor buffers and polishers
Carpet cleaning machines (wet/dry extraction)
Pressure washers
Window cleaning equipment (if applicable)
Steam cleaners
Trolleys, mops, buckets and hand tools
PPE stock (gloves, aprons, masks)
Chemical storage and dispensing equipment
Uniform stock
For each significant item, note whether it is owned outright, leased or subject to a finance agreement, along with its age and condition.
Vehicles
Vehicles can be a significant part of the value. Prepare:
List of all vehicles (vans, cars) used in the business
Ownership status — company owned, personally owned and expensed, leased or on finance
Outstanding finance balances
Age, mileage and condition
MOT and service history
Whether the vehicles are branded
Insurance arrangements
Whether included in the sale
Systems
Prepare access and transfer information for:
Scheduling software— what system is used? Can it be transferred or re-licensed?
Time-tracking or GPS tracking— particularly relevant for demonstrating hours to clients
Payroll software— and whether payroll is handled in-house or outsourced
CRM or client management system
Accounting software(QuickBooks, Xero, Sage)
Google Business Profile— can the buyer take ownership?
Website and domain— registered in whose name?
Social media accounts
Email addresses— are these company domain or personal?
How to write a strong cleaning business listing
A cleaning business listing should lead with recurring revenue and contract quality.
Include:
Commercial or domestic focus (or split)
Broad location and operating area
Trading history (years established)
Monthly recurring revenue (MRR)
Number of clients and client profile
Contract status (broad description — e.g. "majority on written agreements")
Staff overview (employed, subcontracted or mixed — no names)
Equipment and vehicles included
Insurance and compliance overview
Reason for sale
Growth opportunities (e.g. local B2B prospecting, online presence, route expansion)
Handover support offered
Example listing paragraph
Established commercial cleaning business with repeat monthly contracts, documented cleaning schedules, a stable team of trained staff and strong client retention. The business operates across a compact route with consistent demand from office, retail and light industrial clients. Further contract, financial and staffing information is available to serious buyers after screening and confidentiality checks.
Mistakes sellers should avoid
Relying on verbal client arrangements.A buyer cannot value what they cannot verify. Informal contracts are either priced as a risk or excluded from the valuation altogether.
Not preparing a contract summary.Even if you cannot share client names immediately, a summary showing contract profile, notice periods, tenure and monthly value by anonymised client is essential early-stage marketing material.
Hiding staff turnover.High turnover will be discovered during due diligence. It is better to disclose it early with an explanation than to have a buyer discover it and assume the worst.
Ignoring TUPE.Sellers who do not understand their TUPE obligations — and who have not taken advice — create legal risk for both parties.
Missing COSHH records.This is a health and safety requirement, not optional. Missing records raise serious doubts about compliance standards across the business.
Poor keyholding procedures.Insurance coverage, client trust and buyer confidence all depend on documented keyholding. This is consistently one of the most probed areas in cleaning business due diligence.
Overstating recurring revenue.Include only contracted or reliably recurring income in your MRR figure. One-off deep cleans, project work or seasonal contracts should be shown separately.
Sharing client data too early.Client names and contact details are personal data. Share summaries first, raw data only under formal due diligence conditions.
Having no handover plan.A buyer who cannot see how the business runs without you will price the risk of your departure into their offer. A written handover plan — covering client introductions, staff briefings, system access and a transition timetable — materially improves confidence and price.

FAQs
How much is a cleaning business worth?
It depends on maintainable profit, monthly recurring revenue, contract quality, client retention, staff reliability, margins, equipment and owner dependency. A well-run commercial cleaning business with written contracts and stable staff will typically command a higher multiple than a domestic cleaning operation with informal arrangements.
Are cleaning contracts transferable?
It depends on the specific contract. Check the assignment and consent clauses carefully. Some commercial cleaning contracts require the client's consent to transfer. If they do, the buyer's due diligence will usually involve requesting that consent before exchange or making the deal conditional on it.
Does TUPE apply in cleaning?
Yes — and in two ways. TUPE applies to business sales where employees transfer as part of the acquisition. It can also apply to service provider changes, where a client changes cleaning company and the outgoing contractor's staff may transfer to the incoming contractor. Both situations can arise in a cleaning business sale. Take employment law advice early.
What COSHH records do buyers ask for?
Buyers will typically want to see COSHH assessments for all cleaning chemicals used, safety data sheets, PPE policy, manual handling assessment and evidence that staff have been trained on chemical handling and safe working procedures.
Should I share client names before an NDA is signed?
No. Share anonymised summaries — number of clients, monthly value ranges, contract profile, churn rate — in early discussions. Full client names and contact details should only be shared during formal due diligence with an NDA in place and appropriate data protection conditions agreed.
Key takeaways
Cleaning businesses are valued on recurring revenue and contract quality — not just profit.
Written contracts with meaningful notice periods are significantly more valuable than verbal arrangements.
Staff stability, TUPE compliance and subcontractor formalisation all directly affect buyer confidence.
COSHH records and keyholding documentation are standard due diligence items — gaps are a red flag.
Client concentration risk (one large client representing most revenue) reduces value.
Owner dependency is priced into the multiple — the more you can demonstrate a delegated operation, the better.
Stage your disclosure carefully: anonymised summaries first, detailed data only after NDAs and formal due diligence.
A detailed handover plan covering clients, staff, systems and supplier introductions is essential.
