In-House Cleaner vs. Cleaning Company: What Really Pays Off for Businesses?

This question comes up in every company that is growing and starting to take regular cleaning more seriously. An in-house cleaner seems cheaper and simpler to manage. But is it really? Let us break it down with real numbers and scenarios from Prague practice.

The Real Costs of an In-House Cleaner

Companies often calculate only the gross salary. That is a fundamental mistake. The real costs of an in-house cleaner (part-time contract, 4 hrs/day, 5 days/week in Prague 2026) look like this:

• Gross salary: approx. CZK 16,000–20,000/month (depending on rate and hours)
• Cleaning products and equipment: CZK 800–1,500/month
• HR administrative burden: estimated value CZK 1,000–2,000/month (payroll, contract, oversight)
• Cover during absence (illness, holiday): average CZK 1,500–3,000/month (agency temp or other employee overtime)
• Training and onboarding: one-off but real — an estimated 2–5 days of HR productivity

Total: CZK 19,300–26,500/month for an average office of 100–200 m².

Comparison: Outsourcing the Same Office

Regular cleaning of a 100–200 m² office (5× per week) from a professional cleaning company in Prague typically costs CZK 12,000–18,000/month — including products, cover and liability insurance.

The difference of CZK 5,000–8,000/month = CZK 60,000–96,000/year in favour of outsourcing. And that does not count the value of saved management time.

When Does an In-House Cleaner Make Sense?

To be fair: there are situations where an in-house cleaner is the right choice:

• Specific security requirements — government, judiciary, banking sector, where external staff are not permitted
• Specialist facilities — laboratories, healthcare, manufacturing with strict cleanliness standards
• Very large floor areas (5,000+ m²) with their own facility management — where an in-house team is more economical

For a standard office of 50–500 m² without specific security requirements: outsourcing works out better.

Hidden Risks of an In-House Cleaner

• Turnover — hiring, training, hiring again — a recurring cycle
• Liability for damage — as employer you bear responsibility for damage caused by the employee
• Cost increases during absence — especially in winter when sick leave rates are higher
• Quality control vacuum — who monitors cleaning quality? Who raises a complaint about a poor result?

What Companies Say After Switching from In-House to Outsourcing

The most common feedback after switching: "We didn't realise how much hassle it was." Companies most often mention relief from HR administration, the certainty of cover, and better overall consistency of quality. Negatives: adapting to a different system and approach from the cleaners, adjusting the access control system.

Summary: Key Decision Criteria

Choose outsourcing if: you have no specific security requirements, your team is 10–200 people, you want guaranteed quality with the ability to raise complaints, and HR does not have capacity to manage an additional employee.
