Insurance against damage to works

Verified 22 October 2021 - Directorate for Legal and Administrative Information (Prime Minister)

Any person who has the work of constructing, extending or renovating the main structure (framework of the building) carried out by a company must take out insurance work damage (DO). It prefinances, without seeking liability, the repair work for damage covered by the manufacturers' ten-year guarantee. It then turns on the builders and their insurers.

When an individual or a company has construction work done, they have the obligation to take out a non-life insurance (OD). It must be subscribed before the construction site opens to insure the building constructed or rehabilitated.

They may be the owner, seller or agent of the owner of the work (trustee, manager of civil real estate business, property administrator, etc.).

If no insurer wants to insure the construction, the developer may refer the matter to the Central Pricing Office (BCT). The latter will fix the price of the DO guarantee with the insurer chosen by the contracting authority.

Who shall I contact


failure to take out compulsory insurance is an offense punishable by six months' imprisonment and a fine of €75,000 at most or only one of these two sentences. These sanctions do not apply to an individual constructing a dwelling to occupy himself or a member of his family.

The damage insurance (OD) reimburses all the repair work of the damage covered by the ten-year guarantee builders.

It guarantees the faults which affect the solidity of the structure and render it uninhabitable or unsuitable for the use for which it is intended (major cracks, roof collapse, etc.).

It also covers defects which jeopardize the strength of the inseparable components of the structures viability, foundation, framework, fence and canopy. These are elements whose removal, disassembly or replacement cannot be carried out without damaging the construction, as for example for embedded pipes.

OD insurance guarantees apparent or not damage when receiving work.

In principle, it shall take effect at the end of the one-year guarantee of perfect completion.

However, it can cover repairs of damage that fall under the ten-year guarantee where they have been the subject of reservations on receipt of works. The developer enters the DO insurer during the year of perfect completion guarantee when it finds that the contractor does not carry out the repairs after having received a formal notice.


if a house is sold within 10 years of its construction, the notary must specify in the contract of sale whether or not the works are guaranteed by a non-life insurance. The insurance covers all the successive owners of the work.

In principle, work damage insurance starts at the end of the year of perfect completion, 1 year after the receipt of the work.

It expires at the same time as the manufacturers' ten-year civil liability guarantee10 years after receipt of the works.

As soon as you become aware of the claim, you must comply with the deadline set out in your contract. It cannot be less than 5 working days.

You send your return to your insurer by letter RAR: titleContent, by electronic RAR dispatch or against receipt.

You can use the following template:

Declare the claim to its insurer


when the work is sold, the purchaser becomes the beneficiary of the work damage guarantee. It is up to him to take the matter to the insurer in the event of a loss.
