How to Choose an Office Cleaning Company: Criteria, Contract, and Liability Insurance

Selecting an office cleaning provider is a decision that affects your organization's image, data security, team comfort, and operational budget. Key criteria include legal employment of staff (written contracts, no off-the-books work), liability insurance coverage, B2B industry experience, scope of additional services, and schedule flexibility—each of these elements should be verifiable before signing any agreement.

In a Class A office environment, where RODO compliance, occupational health and safety standards, and quality certifications are the norm, your external partner must meet expectations comparable to an in-house facility management team. The decision typically covers a 12–36 month period, meaning a poor choice creates financial, organizational, and reputational costs that are difficult to reverse quickly.

This guide is based on criteria used by facility managers and office managers in procurement processes, and on the experience of companies serving office buildings in Cracow and Katowice since 2020.

In Brief

• Legal employment of staff (written contracts, no off-the-books work) and a stable team keep turnover low and ensure service continuity
• Liability insurance should cover a minimum of 500,000 PLN; industry leaders offer policies up to 1,000,000 PLN
• A dedicated site coordinator, 24-hour backup coverage, and photo reports after every cleaning session are premium service standards
• Verify cleaning product certifications (EU Ecolabel), corporate client references, and ratings on Google Business Profile
• Conduct a 14–30 day pilot audit before committing to a long-term contract and compare offers from at least three providers
• An SLA contract should specify scope, frequency, quality KPIs, termination conditions, and liability for damages

Employment Structure—The Foundation of Service Stability

How a cleaning team is employed directly impacts the quality and continuity of service. Companies that employ staff legally under written contracts (no off-the-books work) and keep a stable team maintain low turnover. High turnover requires continuous onboarding of new personnel and loss of execution standards.

From a facility manager's perspective, legal employment of staff (written contracts, no off-the-books work) on the provider's side also guarantees paid social contributions and workers' compensation insurance. In case of inspection by tax or labor authorities, responsibility falls on the cleaning company rather than the client—provided the contract is properly structured. All Reefa staff are employed legally under written contracts, eliminating the risk of informal employment allegations and ensuring full transparency in personnel documentation.

Lower turnover also translates to data security: in office environments where desks may contain confidential documents, a stable team means reduced risk of RODO breaches. Check your contract to see if the provider commits to a maximum turnover rate and requires new employees to complete training before working unsupervised at your location.

Liability Insurance—Protection Against Operational Risk

The level of liability insurance (OC) is one of the easiest-to-verify indicators of professionalism. The minimum threshold for companies serving office buildings is 500,000 PLN; market leaders offer policies up to 1,000,000 PLN. This amount should cover potential material damage (e.g., server room flooding, IT equipment damage) and non-material losses (e.g., data loss from mishandling confidential documents).

Before signing an agreement, request a current liability insurance policy—the document should include the policy number, insurer name, territorial scope, and expiry date. Verification through the UFG (Insurance Guarantee Fund) registry confirms the policy is active. Some providers include a copy with their commercial offer; if not, this is a red flag.

In practice, Reefa provides every new client with a copy of their 1,000,000 PLN liability policy and proof of paid premiums before service begins. The contract also includes a damage reporting procedure—the site coordinator submits a report to the legal department within 24 hours, initiating the claims process. Ask your potential partner for a clearly documented incident response protocol.

An additional element is the territorial scope clause—if your office has locations in multiple cities, ensure the policy covers all locations under the contract.

Experience and References—How to Verify a Provider's Track Record

Years in business indicate financial and organizational stability. Firms operating for at least 3–5 years have survived the process-building, recruitment, and certification phases and typically have established corporate client service standards. Reefa has been operating in Cracow since 2020 and in Katowice since 2024; client retention is 91%, meaning most contracts are renewed after the first billing period.

References are worth checking across three dimensions:

1. Corporate client list—Does the company serve office buildings comparable to yours (size, profile, HSE requirements)? Reefa's portfolio includes offices of companies such as Ottobock (global leader in medical technology), Diamed medical center, Say Hi! advertising agency, TWW, and Familia.
2. Google Business Profile ratings—An average rating above 4.5/5 and regular company responses to reviews indicate a service-oriented culture. Pay attention to the content of negative reviews and how the company responds.
3. Written references—Official reference letters with client logos and signatures carry more weight than anonymous testimonials on a website. On /krakow/referencje, we publish scanned documents from clients that can be verified.

If a provider refuses to provide any references citing an NDA clause—this is a red flag. Even under confidentiality agreements, it is possible to disclose the general industry ("fintech," "e-commerce") and building size without revealing the client name.

Scope of Services and Schedule Flexibility

A standard office cleaning package in Cracow typically includes vacuuming, floor washing, trash removal, restroom cleaning, and restocking toilet paper and soap. For most facilities this suffices—but it's worth clarifying upfront how the provider handles additional services:

• Window cleaning—included in the monthly fee or billed separately?
• Carpet and upholstery cleaning—frequency, technology (extraction or dry cleaning)?
• Disinfection of high-touch surfaces—particularly important in medical facilities and open-plan offices
• Post-event cleaning—does the company offer availability outside standard hours for conferences and events?

Schedule flexibility is the second consideration: Class A offices often require evening (6:00–10:00 PM) or early morning (5:00–8:00 AM) service to avoid disrupting team productivity. Check whether the provider has sufficient staff coverage in these time slots and whether the team assigned to your location has a fixed or rotating schedule.

In Reefa's model, each facility has a dedicated coordinator overseeing the schedule, monitoring quality, and responding to requests in real time. After each cleaning, clients receive a timestamped photo report, enabling quality monitoring without daily on-site audits. If a regular team member is absent (vacation, sick leave), the coordinator arranges backup within 24 hours—with no service gap.

Cleaning Products, Equipment, and Environmental Certifications

Chemical quality impacts surface durability (hardwood, panels, natural stone) and the health of office users—especially those with allergies or asthma. The EU Ecolabel certificate guarantees that a product meets EU toxicological standards and minimizes environmental impact. Check whether the provider declares a share of biodegradable products in their portfolio—industry leaders reach 70–80%.

Equipment is the second pillar: professional flat mops (Vileda, TTS), vacuums with HEPA filters (capturing 99.97% of PM2.5 particles), carpet cleaning machines (extraction), and service carts with waste sorting (mixed waste, paper, plastic, glass). If a provider arrives with a bucket and cloth, they are not a partner for an office building—that is a domestic standard.

An added advantage is a chemical dilution control system—devices automatically mix concentrate with water in the manufacturer-recommended ratio, eliminating waste and overdose risk. In medical facilities, it's worth asking about HACCP certification and availability of disinfection protocols for high-contact surfaces (door handles, railings, light switches).

Reefa uses only products with EU Ecolabel certification or equivalent, and in sensitive environments (clinics, childcare facilities within our educational portfolio)—preparations approved for food contact.

How to Compare Offers—The Three-Envelope Method

The most effective comparison method is to send parallel requests for quotation (RFQ) to at least three providers. Each receives an identical brief containing:

1. Usable office floor area (m²)
2. Cleaning frequency (daily / 3× weekly / 2× weekly)
3. Standard and additional scope
4. Special requirements (RODO, HSE, service hours)
5. Building infrastructure (number of restrooms, break rooms, conference halls)

A comparison table should include:

Red flags—warning signs in an offer:

• Price significantly (>30%) lower than competitors—may indicate informal employment or quality cuts
• No liability insurance information in the commercial offer
• No dedicated coordinator—requests handled by a general helpline
• Longer termination period for you than for the provider (asymmetry)
• No pilot period option before a long-term commitment

The /porownaj tool on Reefa's website allows you to generate a criteria comparison in PDF format, which you can send to three providers with a request to complete it. Once responses arrive, you have all data in one place.

Indicative rates for office cleaning in Cracow in 2026 (5× weekly frequency, standard scope) start at 1,200 PLN net/month for facilities of 100–150 m². A detailed price breakdown is available on /krakow/cennik. For a custom quote, we offer an online calculator: /krakow/sprzatanie-biur/kalkulator.

In-House Cleaner vs. Cleaning Company—Cost and Risk Analysis

Some organizations consider hiring a full-time cleaner on staff rather than outsourcing. The table below compares both models:

For facilities under 300 m², outsourcing is typically more cost-effective. Above 500–700 m² with daily coverage, some organizations choose a hybrid model: in-house staff plus an external company for specialized services (window cleaning, carpet cleaning).

The SLA Contract—Key Clauses You Cannot Overlook

A service level agreement (SLA) for cleaning services defines mutual obligations. Essential elements include:

1. Scope of services—list of standard and additional tasks with frequency (daily, weekly, monthly, quarterly)
2. Schedule—team presence days and hours
3. Quality KPIs—audit metrics (e.g., "99% of areas pass monthly inspection")
4. Issue reporting procedure—channel (email, app, phone), response time (e.g., <4 business hours), reporting mechanism
5. Liability for damages—deductible amount, reporting protocol, settlement timeline
6. RODO—data processing assignment clause (if staff access confidential documents)
7. Termination periods—symmetric (e.g., 30 days for both parties) or asymmetric (review carefully)
8. Price adjustment terms—index (e.g., CPI inflation) or annual renegotiation

In Reefa contracts, a 30-day pilot period is standard—if you find the standards don't match expectations, you can terminate without financial consequences. This is a two-way test: you verify quality, and we learn the facility's specifics and realistic expectations.

Pay attention to the subcontracting clause—can the company assign work to another firm without your consent? In office environments requiring badge access and HSE registration, this creates risk. Reefa does not use subcontractors—our entire team comprises directly employed staff.

What to Check in Your Contract—Checklist Before Signing

Before final execution, review this checklist:

• Does the offer break down pricing by line item (labor, supplies, equipment) or at least separate standard from additional scope?
• Is a current liability insurance policy attached (expiry date, coverage amount)?
• Does the contract list the dedicated coordinator's name, position, and contact details?
• Is maximum response time to requests specified (e.g., 4 hours on business days)?
• Does the schedule account for holidays and days off (how are shifts rescheduled)?
• Is quality auditing included (frequency, checklist) with consequences for non-compliance?
• Can the contract be terminated immediately for material breach (e.g., theft)?
• Are payment terms clear (due date, bank account, late payment consequences)?

If any point above is unclear or missing—request an amendment before signing. Verbal assurances from sales staff have no legal force.

Pilot Period and Audit—Test Before Long-Term Commitment

Professional providers offer a trial period (14–60 days) for both parties to verify the partnership. This time allows you to:

• Assess cleaning quality (do standards match the offer?)
• Test coordinator communication (response time, problem-solving approach)
• Verify team punctuality and consistency
• Confirm staff compliance with HSE rules and facility regulations

For the provider, it's an opportunity to:

• Understand facility specifics (foot traffic, high-priority areas)
• Optimize the schedule
• Adjust team composition (replace anyone underperforming before pilot ends)

We recommend conducting control audits at day 7 and day 21 of the pilot—a joint walk-through with the coordinator, evaluation forms, and photo documentation. If you notice recurring issues (e.g., missed corners, streaky glass), discuss process adjustments—or terminate if standards aren't met.

Reefa conducts audits every 30 days for the first six months, then quarterly. Each audit produces a PDF report sent to the facility manager, tracking quality trends over time.

Frequently Asked Questions

How much does office cleaning cost?

Cost depends on size, frequency, and scope. For a 100–150 m² office in Cracow with 5× weekly service (standard scope: floors, restrooms, trash removal), rates start at 1,200 PLN net/month in 2026. Facilities over 300 m² or requiring additional services (window cleaning, carpet cleaning) are quoted individually. Detailed pricing is available at /krakow/cennik; use our online calculator /krakow/sprzatanie-biur/kalkulator for a quick estimate. For a personalized quote, Reefa prepares an offer within 24 hours of a site visit—contact us at /krakow/kontakt.

What should an office cleaning company have?

Minimum requirements: active liability insurance (500,000 PLN+), legal employment of staff (written contracts, no off-the-books work), a dedicated site coordinator, professional equipment with HEPA filtration, products with EU Ecolabel or equivalent certification, documented corporate client references, and a clear issue reporting process. Class A office environments additionally expect: photo reports after each session, mobile app or QR code for real-time issue logging, HSE and RODO training for staff, guaranteed 24-hour backup coverage, and a pilot period before contract signing. Reefa meets all these criteria, serving office buildings since 2020 in Cracow and since 2024 in Katowice.

Does a cleaning company need liability insurance?

Legally, there is no absolute requirement, but in B2B practice, the lack of a policy disqualifies a provider. Liability insurance protects you from material and non-material losses resulting from provider error (e.g., server room flooding, computer equipment damage, document loss). The minimum for office buildings is 500,000 PLN; Class A office cleaning companies carry policies up to 1,000,000 PLN. Before signing, request a current policy copy with expiry date and insurer name—the document must remain valid for the entire contract period. Reefa holds a 1,000,000 PLN liability policy, attached to every contract.

In-house cleaner or cleaning company—what makes more sense?

For facilities under 300 m², outsourcing is typically cheaper and lower-risk. Hiring a full-time cleaner in 2026 costs approximately 5,500 PLN gross/month (salary + taxes + benefits), plus equipment, supplies, and backup staffing for vacation/sick leave. An external company provides service from 1,200 PLN net/month (~120 m² facility), with equipment and supplies included, guaranteed backup coverage, and liability insurance. You receive a VAT invoice instead of managing an employment contract. A full-time hire makes sense for facilities >500 m² with daily coverage and additional duties (reception, HSE, minor repairs). Consider a hybrid model: in-house staff for core duties and external specialists for window/carpet cleaning.

What should I check in a cleaning company contract?

Key clauses: detailed scope with frequency (standard + additional), team presence schedule, liability insurance amount and damage settlement terms, quality KPIs and audit procedures, legal employment of staff (written contracts, no off-the-books work), coordinator contact details, response time (<4 business hours), symmetric termination periods (30 days recommended), RODO data-processing clause, price adjustment terms (CPI inflation or annual renegotiation), and no subcontracting without approval. Verify the contract includes a pilot period (14–60 days) with penalty-free termination. A pre-signing checklist prevents misunderstandings.

How do I verify a cleaning company's credibility?

Check three sources: (1) Written references from corporate clients—the list on /krakow/referencje should include scanned documents with client logos and signatures; (2) Google Business Profile ratings—average >4.5/5 with regular company responses; (3) Business age and status—search the company's registration number (NIP) in CEIDG or the business registry to confirm legal standing and founding date. Additional signals: active LinkedIn profile with visible team, ISO 9001 or equivalent certifications, membership in industry associations. Red flags: missing business details on the website, refusal to provide tax ID, no phone contact (email only), generic email addresses. Request the liability policy copy before a site visit—a professional provider will send it within hours.
