Facing a claim, cracks, or construction defects, you’re wondering which expert to consult. Two options are available: the independent building expert and the insurance expert. While their missions may seem similar, their processes, impartiality and cost differ significantly. ## The Independent Building Expert ### Who Are They? The independent building expert is a certified professional, usually an engineer or architect, who works in a private capacity. You instruct them directly to assess the condition of a property, diagnose problems, or estimate the works required. ### Their Mission - Detailed diagnosis of defects or structural issues - Estimate of repair costs - Advice on the safety and habitability of a property - Assessment of the liability of builders or tradespeople - Analysis for disputes or property transactions ### Impartiality and Accountability Although you pay them directly, the independent expert must follow a strict code of professional ethics. They are civilly and criminally liable for their conclusions. Their interest? To give you a reliable report you can use in court if needed. ### Cost You pay their fees directly (generally between €800 and €3,000 depending on complexity). This cost can later be recovered from the party responsible for the damage or defect. ## The Insurance Expert ### Who Are They? The insurance expert is a professional instructed by your insurance company after you file a claim. Their role is to assess the damage covered by your policy and propose a level of compensation. ### Their Mission - Record the damage and its cause - Check what the policy covers - Estimate the amount of compensation - Propose repair solutions (excess, cost-sharing) - Act as arbitrator in case of disagreement between policyholder and insurer ### Impartiality and Conflicts of Interest This is where the key difference lies. Although theoretically impartial, the insurance expert represents the interests of the insurance company that instructed them. There’s a real risk of bias, particularly toward minimising the payout. That’s why you have the right to challenge their report by bringing in an independent expert. ### Cost Survey fees are generally covered by the insurer (unless there’s an excess on the survey itself). For you, it’s free or almost free. ## Direct Comparison | Criterion | Independent Expert | Insurance Expert | | --- | --- | --- | | **Who instructs them?** | You, directly | Your insurer | | **Impartiality** | High (directly accountable to you) | Relative (instructed by the insurer) | | **Cost** | Paid by you (€800 to €3,000) | Free or almost free | | **Legal standing** | Report usable in court | Can be challenged via a counter-survey | | **Priority** | Your satisfaction and the quality of the diagnosis | Handling the claim under the policy terms | | **Scope** | Any type of building issue | Claims covered by the insurance policy | ## Which One Should You Use, and When? ### Choose the Independent Expert If: - You suspect a hidden defect before buying a property - You have construction defects (cracks, damp, insulation problems) - You want to estimate renovation costs - A claim isn’t covered by your insurance - You disagree with the insurance expert’s findings - You’re considering legal action against a builder or tradesperson ### Accept the Insurance Expert If: - You’ve filed a claim that’s covered (storm, water damage, fire) - You want a quick resolution to the claim - You want to avoid additional survey fees ## Special Case: The Second-Opinion Assessment If you disagree with the insurance expert’s report, you have the right to bring in an independent expert for a **counter-survey**. The two experts compare their findings. If the disagreement persists, arbitration may be required. ## Practical Advice - **Before buying:** Invest in an independent building expert (a small cost compared to the purchase price). - **After a claim:** Accept the insurer’s survey first, then challenge it if you have doubts. - **Selection:** Choose a certified expert (OPQIBI or equivalent), with professional liability insurance. - **Documentation:** Build a complete file (photos, quotes, older documents) to support your case. ## Conclusion The independent building expert and the insurance expert play complementary but different roles. The independent expert defends your interests impartially, while the insurance expert handles the claim according to the terms of your policy. For the best protection, don’t hesitate to use both: an independent survey upfront (before signing), and the insurer’s survey afterwards (following a claim), backed up by a counter-survey if needed. ## Related Reading - [Off-Plan (VEFA) Survey](https://cassini-expertise.fr/expertise-vefa-06-83/) - [Crack Diagnosis (RGA)](https://cassini-expertise.fr/diagnostic-fissures-rga-06-83/) - [Independent Expert](https://cassini-expertise.fr/expert-batiment-independant-aucun-travaux-aucun-materiel-vendu/) Have a doubt?
