Commercial vs Domestic Cleaning: What's the Difference?

Two Different Industries

Commercial cleaning and domestic cleaning are often lumped together under the general term “cleaning services,” but they are fundamentally different industries serving different markets with different equipment, insurance, pricing, regulations, and customer expectations. Understanding these differences matters whether you are a business looking for a cleaning contractor, a homeowner seeking a domestic cleaner, or an entrepreneur considering starting a cleaning business.

What Is Commercial Cleaning?

Commercial cleaning serves non-residential premises: offices, retail stores, factories, warehouses, hospitals, schools, hotels, restaurants, data centres, and any other business or institutional building. Commercial cleaning is typically performed under contract (monthly, quarterly, or annual agreements) with defined specifications, frequencies, KPIs, and audit mechanisms. The work is often performed outside business hours — evenings, nights, or early mornings — to avoid disrupting the client’s operations.

Commercial cleaning companies employ teams of operatives managed by supervisors and area managers. They deploy industrial equipment, use commercial-grade chemicals (often through concentrated dispensing systems), and operate under formal quality management systems. Contracts range from small offices (€300–€500/month) to large facilities (€10,000–€50,000+/month for hospitals, shopping centres, or corporate campuses).

What Is Domestic Cleaning?

Domestic cleaning serves private homes and apartments. Services include regular scheduled cleaning (weekly, fortnightly, or monthly visits), one-off deep cleans, end of tenancy cleans, and spring cleans. Domestic cleaning is performed during daytime hours when the homeowner may or may not be present. Equipment is typically household-grade: standard vacuum cleaners, mops, cloths, and retail cleaning products (although some domestic cleaning companies are moving toward professional-grade equipment).

Domestic cleaning is priced per visit or per hour rather than on monthly contracts. A typical domestic clean in Ireland costs €15–€20 per hour or €60–€120 per visit for a standard 3-bed house. Domestic cleaners may be self-employed individuals, employees of a domestic cleaning company, or workers found through cleaning platforms and apps.

Key Differences at a Glance

Equipment Differences

The most visible difference between commercial and domestic cleaning is equipment. Commercial cleaning deploys industrial machinery that delivers cleaning results impossible to achieve with household tools:

• Ride-on scrubber-dryers — Clean 3,000–5,000 sqm/hour. Essential for warehouse floors, shopping centres, airports, and factory floors. No domestic equivalent exists.
• Rotary floor machines — Disc machines that scrub, polish, and buff hard floors. Used in offices, hospitals, and retail premises for floor maintenance programmes.
• Hot water extraction machines — Professional carpet cleaning machines that inject hot water and detergent under pressure, then extract the dirty solution. Far more powerful than domestic carpet washers.
• Pressure washers — Industrial units delivering 150–300 bar for external cleaning of building facades, car parks, loading bays, and forecourts.
• Powered access platforms — Cherry pickers and scissor lifts for high-level cleaning in warehouses, atriums, and multi-storey buildings.
• Concentrated chemical dispensing — Wall-mounted systems that dilute concentrated chemicals to precise ratios, reducing waste and ensuring consistent cleaning strength.

Insurance Requirements

Insurance is one of the most critical differences. Commercial cleaning contracts specify minimum insurance levels, and failure to meet them disqualifies the cleaning company from tendering.

Commercial cleaning insurance (typical requirements):

• Public liability: €6.5M minimum, €13M for healthcare/education/government, €20M for pharmaceutical/data centres
• Employer’s liability: €13M (standard across the industry)
• Professional indemnity: €1.3M–€2.6M for FM contracts and public tenders
• Motor fleet insurance for company vehicles
• Equipment and stock insurance

Domestic cleaning insurance:

• Public liability: €2M–€6.5M (many sole traders carry none)
• Employer’s liability: often absent (sole traders with no employees)
• Professional indemnity: not required

Pricing Models

Commercial and domestic cleaning use fundamentally different pricing models:

Commercial Pricing

• Hourly rate x hours x frequency — The standard model. If a site needs 3 operatives for 4 hours, 5 days/week, at €15/hr: 3 x 4 x 5 x €15 x 4.33 weeks = €3,897/month.
• Per-square-metre rate — Used for warehouse, industrial, and large retail: €0.15–€8.00/sqm depending on service type.
• Fixed monthly price — Most common in practice. The cleaning company quotes a monthly price based on their site survey assessment.
• Bundled pricing — Combining cleaning, washroom services, window cleaning, and consumables under one contract at a discount.

Domestic Pricing

• Per hour — €15–€20/hour. Client pays for actual hours worked.
• Per visit — €60–€120 for a standard 3-bed house. Fixed price regardless of time taken.
• Per service — One-off pricing for deep cleans (€200–€400), end of tenancy (€250–€500), oven cleaning (€50–€90).

Qualifications and Training

Commercial cleaning increasingly requires formal qualifications and sector-specific training:

• Safe Pass — Required for any person working on a construction site in Ireland. Essential for post-construction cleaning teams.
• COSHH / Chemical Safety — Understanding of Safety Data Sheets, chemical hazards, dilution rates, and PPE requirements. See our COSHH guide.
• Manual Handling — Legally required training for employees who perform manual handling tasks (which includes cleaning).
• Garda Vetting — Required for cleaning staff working in healthcare settings, schools, childcare facilities, and other regulated environments. See our Garda vetting guide.
• Colour-Coded Cleaning — The four-colour system used in healthcare, food processing, and laboratory environments. See our colour-coded cleaning guide.
• Fire Safety — Awareness training required for all employees working in commercial premises.
• IPAF — Certification for operating powered access platforms (cherry pickers, scissor lifts).

Domestic cleaners are not required to hold any of these qualifications, though professional domestic cleaning companies increasingly invest in staff training for quality and safety reasons.

Scheduling Differences

Commercial cleaning operates on a fundamentally different schedule:

• Out-of-hours cleaning — Most office and retail cleaning happens after business hours (6pm–10pm or 5am–8am). See our night vs day cleaning guide.
• 24/7 operations — Hospitals, data centres, and fulfilment centres require continuous cleaning coverage across all shifts.
• Weekend and bank holiday cover — Hotels, retail, and healthcare require 7-day coverage. ERO rates apply for Sunday work (double time).
• Seasonal surges — Retail at Christmas, hospitality in summer, construction completions in Q4.

Domestic cleaning is almost exclusively performed during weekday daytime hours (9am–5pm), Monday to Friday.
