Business liability insurance: protection against third-party damage claims

A customer falls in the shop, an employee accidentally damages someone else's property during an off-site appointment: incidents like these can quickly put a business without suitable insurance cover in serious financial difficulty. Contrary to what many expect, taking out cover for this is not a given in Germany but a business decision.

In brief: business liability insurance is not a legal requirement but voluntary cover for businesses. It covers personal injury, property damage and financial loss caused to third parties by business operations. Practically every business with customer contact, on-site work or product use is affected – without cover, it is liable with its own assets in the event of a claim.

Who should take out business liability insurance?

Unlike motor liability insurance, for example, there is no general legal obligation to have business liability insurance – the specialist catalogue expressly classifies it as voluntary cover. It still makes sense for practically every business with customer traffic, work on third-party premises or product use, because that is exactly where the risk of damage to third parties arises. This applies to shops with foot traffic just as much as to trade businesses working on customers' premises or service providers who come into contact with other people's property.

For regulated professions such as lawyers, tax advisers or doctors, by contrast, a separate, legally prescribed professional liability insurance with a statutory minimum cover applies. This is a separate obligation and does not automatically replace business liability insurance, but is added to it where needed. If you operate in both capacities – for example a law firm with walk-in clients – you should check whether both types of cover are necessary.

Which risks does business liability insurance cover?

The insurance applies to personal injury, property damage and financial loss caused to third parties by business operations. Typical examples are a customer who falls in the shop or an employee who damages someone else's property during an on-site job. Such claims for damages can reach amounts that a business without insurance cover cannot bear on its own.

It is crucial that the cover matches the actual business operations. A business without customer traffic has different risks from one whose employees regularly work at customers' premises – the policy should reflect these differences instead of adopting a blanket standard cover.

How do you take out the right policy?

It is best to follow a fixed process that systematically records the business risks and bases the sum insured on them, instead of hastily choosing the first offer. If you work through the individual steps carefully once, you can then review the policy regularly instead of losing sight of it after signing. A tool such as Company Audit shows you which further obligations and types of cover are relevant for your business.

1. Record the business risks: customer traffic, work on third-party premises, product use.
2. Estimate the sum insured based on the largest realistic claim.
3. Compare offers: weigh up scope of cover, exclusions and deductible.
4. Take out the policy and archive the insurance certificate.
5. Adjust the cover when the business expands – for example new locations or new activities.

In practice, the last step is often overlooked: when a business grows, its risk profile usually changes as well – a policy that was suitable when it was taken out can be too narrow years later.

What happens without business liability insurance?

Without its own insurance, the business is in principle liable with its own assets in the event of a claim. Since there is no legal obligation for business liability insurance and therefore no prescribed minimum sum, the protection depends entirely on the individually chosen policy. If no policy is taken out, there is accordingly no insurance cover in the event of a claim.

For management, this means a conscious trade-off: the voluntary cover costs ongoing premiums, whereas a single major claim without insurance can threaten a business's existence.

Frequently asked questions

Is business liability insurance mandatory?

No. The specialist catalogue expressly classifies it as voluntary cover – unlike motor liability insurance, for example, there is no general legal obligation. The decision for or against a policy therefore rests solely with the business.

How high should the sum insured be?

The largest realistically conceivable claim in your own business serves as a guide. The sensible sum insured is based on that before offers are compared – there is no blanket figure, as it depends on the individual risk.

Does the cover also apply to new locations or activities?

Not automatically. When the business expands, for example with new locations or new activities, the existing cover should be reviewed and adjusted if necessary so that no newly arisen risks remain uninsured.

What is the difference from professional liability insurance?

For regulated professions such as lawyers, tax advisers or doctors, professional liability insurance with a statutory minimum cover is mandatory. This is a separate obligation and not an alternative to business liability insurance.

Is a group contract through a professional association worthwhile?

In many cases, yes: some professional associations offer group contracts with better terms than individually taken-out single policies. A comparison with the independent market offering is still worthwhile before signing.
