Types of Construction Insurance
Works Damage Insurance
The works damage insurance is mandatory for all owners. It covers repair work for damages under the decennial guarantee. This insurance allows for rapid reimbursement without waiting for a court decision.
The works damage insurance applies to all construction work, extensions, or renovations of the main structure (building frame). It covers losses that threaten the structural integrity of the building or make it unsuitable for its purpose, such as roof collapses, major cracks, and ruptures of embedded pipes. The subscription must be made before the start of work and allows for pre-financing of repair work, ensuring quick handling of damages without waiting for a court.
Decennial Civil Liability Insurance
The civil liability decennial insurance is essential for builders. It guarantees repair of issues affecting the structure of the work. The subscription to this insurance is mandatory before starting work.
This insurance covers damages appearing after the handover that compromise the structural integrity of the work or make it unsuitable for its intended use. It protects the builder against claims for ten years following the handover. Building professionals, such as architects, contractors, and artisans, must subscribe to this insurance before starting work to avoid financial and legal risks related to defects.
All Risks Site Insurance
The all risks site insurance covers material damages occurring during works. It is especially useful for companies. This insurance protects against Theft, fire, and natural disasters.
This insurance is designed to protect the project owner, contractors, and project managers against accidental or unexpected damages that may occur on site. It covers materials, equipment, and the structure under construction against risks such as fire, explosions, thefts, vandalism, and natural catastrophes. The subscription must be made before work begins, and coverage ends at the handover.
Project Owner’s Civil Liability (RCMO)
The project owner’s liability covers damages caused to third parties. It is similar to Professional Liability, but applies to clients of the project. The subscription must be made before the start of work.
RCMO protects the project owner against claims for damages caused to third parties during construction. This includes bodily, material, and non-material damages resulting from faults or negligence on site. It applies to individuals, communities, and contractors commissioning the work. This insurance is crucial to avoid costly litigation and ensure adequate legal protection.
Non-Builder Contractors (CNR)
Non-builder contractors must subscribe to decennial insurance. This insurance covers damages affecting the structure of the work. It is mandatory for professionals and recommended for individuals.
The CNR insurance applies to property developers, lot buyers, and sellers who do not carry out the work themselves but assume liability. It guarantees the repair of decennial damages affecting the structure or making it unsuitable for its purpose. Individuals selling a property within ten years of construction are also encouraged to subscribe to this insurance to avoid disputes with buyers.
Completion Financial Guarantee (GFA)
The financial guarantee for completion is necessary for VEFA purchases. It ensures the funding of project completion. This guarantee protects buyers against the risk of unfinished work.
The GFA is required from property developers to ensure that work will be completed even in case of financial failure. It provides security to buyers by guaranteeing that the funds necessary for project completion will be available. This insurance is subscribed before work begins and remains in force until the declaration of completion (DAT). It is especially important for buyers in future state of completion sales (VEFA) who want to secure their investment.

How to Subscribe to Construction Insurance?
To subscribe to construction insurance, you need to compare offers from different companies. Choosing the best coverage at the best price is crucial. An broker can help you find solutions tailored to your needs.
Compare Offers
The first step to subscribing to construction insurance is to compare available offers. It is important to check the guarantees offered, franchises, exclusions, and general conditions of each contract. By comparing multiple quotes, you can identify the best deal based on your budget and specific needs.
Assess Your Needs
Every construction project has specific insurance needs. It is essential to clearly define what you need based on the nature of the work, the size of the project, and potential risks. For example, a large site will likely require a broader coverage than a small renovation project.
Consult an Broker
Consulting a insurance broker can be very useful. Brokers have an in-depth knowledge of the insurance market and can help you negotiate the best conditions. They can also advise you on the types of insurance needed and guide you throughout the subscription process.
Verify Certificates
Before subscribing to insurance, it is important to verify the certificates of insurance of the contractors and builders involved in your project. Make sure these professionals are well covered by decennial liability insurance and that they are up to date on their premiums.
Analyze Exclusions and Franchises
Exclusions and franchises are key elements in an insurance contract. Exclusions specify what is not covered by the policy, while franchises represent the part of damages you will need to pay in case of a claim. Ensure you understand these elements well to avoid unpleasant surprises in case of claim.
Negotiate Conditions
Once you have selected an offer, it can be helpful to negotiate the conditions with the insurer. This can include reducing franchises, extending guarantees, or adjusting premiums based on your specific needs. Do not hesitate to discuss all details to obtain optimal coverage.
Subscribe and Manage the Contract
After choosing and negotiating your insurance, it’s time to subscribe to the contract. Make sure to read and understand all conditions before signing. Once subscribed, it is important to manage the contract and keep all necessary information up to date. Notify your insurer of any changes in your project that may affect the coverage.
Maintain Good Communication
Maintaining good communication with your insurer is essential. In case of claim, a rapid and precise declaration can accelerate the compensation process. Always keep copies of all documents related to your insurance and ensure your contact details are current.
Risks in Case of No Insurance
Not subscribing to insurance can lead to heavy sanctions. You might face very long reimbursement delays. In case of resale, you are responsible for damages during ten years.
Legal Sanctions
The absence of construction insurance exposes owners and contractors to severe legal sanctions. Indeed, not subscribing to damage-works or decennial liability insurance can entail substantial fines and even imprisonment. These sanctions are designed to ensure protection for buyers and third parties.
Delays in Indemnifications
Without insurance, indemnification in case of disaster can take a long time. Legal procedures to establish liability are often lengthy and complex. During this time, necessary repairs cannot be performed, which can worsen damages and increase final costs.
Liability in Case of Resale
If you sell your property without having subscribed to insurance, you remain responsible for damages for ten years after the handover. This means any problem occurring during this period will be under your financial and legal responsibility. New owners could pursue you for damages not covered by insurance, leading to potentially huge costs.
Repair Costs at Your Expense
In case of disaster without insurance, all repair costs will be at your charge. Repair works can be extremely expensive, especially for major damages such as structural cracks or waterproofing issues. Without insurance, these costs can quickly become prohibitive.
Funding Difficulties
Banks and financial institutions often require proof of insurance to grant loans for construction. Without insurance, it may be difficult to obtain financing, delaying your project or increasing borrowing costs.
Impact on Resale Value
A property without insurance may be less attractive to buyers. The presence of adequate insurance is often a sign of security and reliability for buyers. Without it, your property’s resale value could be significantly reduced.
Loss of Peace of Mind
Not having insurance exposes you to ongoing worries about risks. Knowing you will have to bear all costs in case of problems can be a major source of stress. Insurance offers peace of mind, knowing you are protected against unforeseen events.
Conclusion
Construction insurance is an indispensable protection for all actors in the building industry. It covers the financial and legal risks associated with work. Make sure to choose the right insurances to guarantee the security of your project.
