Insurance for bricklaying and building contractors in Germany
In building construction a lot hinges on a few decisions: how deep to excavate, how to support the neighbouring house, who locks the container at night. The big claims here do not come from tools but from the building shell itself. This page explains which insurance your business needs and what it costs.
The question almost everyone asks first
Who pays if the house next door cracks while we dig the foundation pit?
Your public liability policy, if damage from underpinning, undermining and subsidence is included. Exactly this kind of damage is excluded or capped in many standard policies because it can get expensive. Get the extension confirmed in writing and have the condition of the neighbouring house recorded in a pre-construction survey before work starts.
What goes wrong in this trade
- 01
Cracks next door
Excavation, underpinning and vibrating plates set neighbouring buildings moving. Cracks in facades and cellars quickly lead to six-figure claims.
- 02
Your own building shell
A storm topples freshly built gables, rain floods the basement slab, vandals spray the walls: until handover, that is your loss.
- 03
Theft from the site
Plate compactors, lasers, generators and copper disappear from containers overnight.
- 04
Cranes and loads
Suspended loads over other people's land, a toppled crane: few events are as expensive.
- 05
Cables and pipes in the ground
When digging for foundations, power, gas and fibre optic lines get hit. The network operator invoices the repair and the outage.
- 06
Accidents on site
Falls from scaffolds and floor openings, falling bricks, machinery accidents: building construction is among the most accident-prone sectors.
Compared with other trades, 1 low to 5 high.
The insurance you need
Essential
Contractors all risks
Contract works insurance protects the building shell until handover against storm, water, vandalism and theft of installed parts; as an annual policy for all sites.
Strongly advised
Machinery breakdown
Covers crane, excavator, plate compactors and mixing plants against breakage, operating errors and theft.
Fleet insurance
Lorries, flatbeds and vans under one fleet policy are easier to manage and often cheaper.
Business contents
Replaces the yard, workshop and office after burglary, fire and storm.
Depends on the business
Group accident insurance
Extra benefit for employees after accidents, including in their free time; a selling point in the competition for skilled workers.
Business legal expenses
Business legal expenses cover for disputes over variations, interim invoices and delays with clients and main contractors.
What it costs: example prices
Building contractors pay more than finishing trades, because damage to neighbours, underground lines and crane claims are expensive. As turnover grows, insurers' quotes vary widely.
| Insurance | Example | Typical range |
|---|---|---|
| Business liability | €50,000 turnover, €3 to €5 million cover, €250 excess | about €430 to €900 a year |
| Business liability | €200,000 turnover, €3 to €5 million cover | about €490 to €970 a year |
| Business liability | €1 million turnover, €3 to €5 million cover | about €1,330 to €4,050 a year |
| Contractors all risks | single house with €900,000 construction value, up to 24 months | about €1,100 a year according to a sample calculation |
| Machinery breakdown | Construction machinery and small equipment worth €100,000 | about €1,000 to €2,500 a year |
For comparison: Liability insurance for a small bricklaying business costs about as much per year as ten to fifteen square metres of internal brick wall.
Guide prices excluding German insurance premium tax, as of September 2026. Liability and contract works come from published examples; machinery is a guide value from our quoting practice. For contractors an annual policy covering all sites, charged on annual construction output, usually pays off. We obtain the exact quote for you.

Practical tips from your broker
- Have damage from underpinning, undermining, subsidence and vibration included with an adequate limit.
- Take out contract works insurance as an annual policy instead of insuring each site separately.
- Choose at least €5 million combined cover, and rather €10 million for public clients and blocks of flats.
- Commission a pre-construction condition survey before excavating next to existing buildings; it settles disputes about old and new cracks.
- Obtain utility plans and document your enquiries: without proof, the insurer can reduce payment for damage to underground lines.
- Check whether joint ventures and subcontractors are covered under your policy.

Questions and answers
Frequently asked
What insurance does a bricklaying business need?
Public liability is essential. If you build new houses, you also need contract works insurance, and machinery insurance for expensive equipment.
How much does liability insurance cost in building construction?
Published comparisons show about €430 to €900 a year at €50,000 turnover and about €1,330 to €4,050 at €1 million turnover.
What is contract works insurance?
In German it is called Bauleistungsversicherung. It protects the building under construction until handover against unforeseen damage such as storm, water, vandalism and theft of installed parts. Liability insurance does not pay for this damage.
Are cracks in the neighbouring house covered?
Only if underpinning and subsidence damage is included. That is an important point when comparing, because basic tariffs exclude this damage.
Who pays if the excavator hits a gas pipe?
Your public liability policy, if you obtained the utility plans and worked carefully. Without those enquiries, the insurer can reduce payment for gross negligence.
Are subcontractors covered by my insurance?
Your liability for subcontractors you hire is usually covered, but their own liability is not. Ask subcontractors for their own proof of insurance.
