Insurance for commercial cleaning companies in Germany
Your staff hold the keys to offices, surgeries and entire office towers. A lost master key means a new locking system, and that can easily cost more than a year's turnover with that client. Add scratched floors, etched surfaces and wet stairs. This page shows what you need to cover and what it costs.
The question almost everyone asks first
What happens if one of my cleaners loses a client's master key?
The client will ask you to replace the locking system, which in office buildings often costs 20,000 to 80,000 euros. Public liability only pays if the loss of third party keys is expressly included, and only up to the agreed limit. Some insurers exclude stolen keys. Get the limit for keys and access cards confirmed in writing.
What goes wrong in this trade
- 01
The lost master key
A bunch of keys that opens 200 doors goes missing. The property manager replaces the entire locking system and sends you the bill.
- 02
Wrong product, wrong floor
Acidic cleaner on marble, a scouring pad on stainless steel, too much water on parquet. Damage to surfaces you work on causes more disputes in this trade than anything else.
- 03
Wet stairs, broken leg
A tenant slips on freshly mopped stairs. If there was no warning sign, you are liable for treatment and compensation.
- 04
Water in the office below
A knocked over bucket or an overflowing scrubber dryer, and the water comes through the ceiling into the law firm downstairs.
- 05
Suspicion after the shift
A laptop is missing from the office and the client suspects your staff. Employees who enter other people's premises alone are a risk of their own.
- 06
Ladders, chemicals and backs
Window cleaning on ladders, skin irritation from cleaning agents, heavy machines: accident rates in commercial cleaning are high.
Compared with other trades, 1 low to 5 high.
The insurance you need
Essential
Strongly advised

Depends on the business
Group accident insurance
Pays out for your staff's accidents in their free time too, and helps when you are trying to recruit.

Company pension (bAV)
A company pension helps you keep reliable site managers and supervisors.
What it costs: example prices
The premium depends mainly on turnover or payroll, on the type of site (offices, clinics, industry) and on the limit for loss of keys. High level window cleaning and industrial cleaning cost more.
| Insurance | Example | Typical range |
|---|---|---|
| Business liability | Self employed cleaner, about 25,000 euros turnover, with loss of keys | about 150 to 350 euros a year |
| Business liability | Cleaning company with about 100,000 euros turnover, 1,000 euros excess | about 450 to 900 euros a year |
| Business liability | Business with 15 employees, loss of keys up to 100,000 euros | about 1,200 to 3,000 euros a year |
| Business contents | Machines and materials worth 30,000 euros | about 120 to 300 euros a year |
| Business legal expenses | Employment and contract legal cover, up to ten employees | about 400 to 900 euros a year |
For comparison: Public liability for a small cleaning company costs roughly as much per year as two months of regular cleaning for a small office.

Practical tips from your broker
- Agree at least 100,000 euros for keys, access cards and transponders. Office buildings and hospitals have large locking systems.
- Check whether stolen keys are covered as well, not only lost ones.
- Include damage to floors, glass and surfaces you work on, with a limit that suits your sites.
- Name special services such as window cleaning from a cherry picker, post construction cleaning or disinfection in the policy.
- Ask for cover for damage caused by subcontractors if you pass on jobs.
- Keep a key log with a signature at every handover. It helps with claims and with accusations against your staff.

Questions and answers
Frequently asked
Is public liability compulsory for cleaning companies in Germany?
Not by law. In practice you will hardly win a commercial contract without proof, because property managers and companies require it in their tenders.
Does insurance pay if a key is stolen?
It depends on the policy. Some insurers only cover loss, others theft as well. Check the exact wording and the limit.
What does insurance for a cleaning company cost?
For solo self employed cleaners, public liability starts at about 150 euros a year; with around 100,000 euros turnover you are usually between 450 and 900 euros.
Are mini jobbers covered by the statutory accident insurer?
Yes. Mini jobbers (marginal part time staff) must also be registered with BG BAU. They then have statutory accident cover at work and on the way there.
Who pays if a cleaner breaks something at a client's premises?
Your public liability policy, if she acted negligently. Your employees are covered under your policy.
Does liability cover theft by my own staff?
No, deliberate acts are never covered by liability insurance. That needs fidelity insurance (Vertrauensschadenversicherung), which we can request separately if needed.
