Has your insurer rejected a claim because an alarm, inspection or other prevention measure was missing? Then the exact wording of the policy clause is decisive. Examine which obligation applied, whether you complied with it and what consequence is attached to a failure to comply. The absence of a link between the measure and the loss may be relevant, but it does not automatically entitle you to cover under every clause.

Ask the insurer for the specific provision, the failure it has established and the grounds for the rejection. At the same time, gather certificates, maintenance records and correspondence with your adviser. A prevention dispute often calls for both a legal interpretation of the policy and technical evidence about the actual situation.
What is a prevention clause?
A prevention clause contains agreements intended to reduce the likelihood of loss or its extent. Think of a specific vehicle tracking system, burglary protection, maintenance or an inspection of electrical installations. The requirement may appear on the policy schedule, on a clause sheet or in the policy conditions.
Not every policy uses the same wording. One provision describes the circumstances in which a risk is insured; another imposes an obligation and attaches a sanction to it. That distinction can affect interpretation, evidence and the significance of the link with the loss.
So start with the complete contract. A commercial product name such as all-risks says little about specific security requirements. Nor does an oral summary by your adviser simply replace the clause, although that communication may be relevant to interpretation or liability.
Which prevention requirements are common?
| Type of requirement | Examples of relevant evidence |
|---|---|
| Alarm or vehicle tracking system | Certificate, proof of installation, subscription and inspection reports |
| Electrical inspection | Inspection report, scope of the inspection and proof that defects were remedied |
| Fire safety | Maintenance records, storage rules and inspection reports |
| Burglary protection | Locks, security plan and proof that the system was activated |
| Periodic maintenance | Invoices, reports and recorded intervals |
A certificate may prove only part of the obligation. Sometimes the system must also be active, maintained or connected. Conversely, a missing document does not automatically mean that the technical measure was actually absent. Ask which element the insurer disputes.
Step one: determine which conditions apply
Find the policy schedule and the conditions that applied on the date of the loss. Check for amendments and any special arrangements. A new version on the website is not automatically the version that applies to your loss. So keep older documents and messages about policy changes.
If general and special provisions conflict, it must be examined how the agreement should be interpreted. The position of the clause, its wording and the communication may be relevant. For consumers, rules on unclear or unreasonably onerous terms may also come into play.
Relying on a lack of clarity does, however, require a genuine dispute about meaning. The mere fact that you did not read the clause does not automatically invalidate a clear and properly provided provision. Explain which interpretation you were entitled to expect and on what basis.
Step two: read the requirement and the consequence separately
Ask exactly what you were required to do and when. Did the system have to be in place at inception, be installed within a certain period or be used continuously? Which class, standard or certification was required? A comparable system does not necessarily meet a specifically described requirement.
Next, read which consequence is attached to non-compliance. Some clauses contain an exception if the failure did not contribute to the loss. Others describe the insured cover itself. The legal characterisation follows from the content and context, not merely from the heading above the provision.
Ask the insurer to identify both elements. A rejection that merely states that “the prevention measures were not in order” often fails to make clear which fact and which contractual consequence are at issue. That hampers a targeted response.
When does the link with the loss matter?
If the policy itself contains a causation exception, it must be applied in accordance with its wording and context. It may then be relevant whether the absence of a measure affected the occurrence or extent of the loss. Technical investigation may be necessary for that purpose.
Even outside an express exception, the link with the loss may be legally relevant, for example when assessing reliance on a forfeiture clause or the limiting effect of reasonableness and fairness. The test does, however, depend on the type of clause and the circumstances.
You therefore cannot argue in general terms that every prevention shortcoming without demonstrable causation must be disregarded. In principle, an insurer is free to determine which risks it covers. Have the contractual scope established first before you commission a technical counter-investigation into what may be the wrong question.
An alarm that was present but did not comply
A vehicle or building may be secured while the system does not meet the agreed class. An expired certificate, a switched-off system or a terminated monitoring centre subscription may also be relevant if the clause sets requirements for them. Examine the situation on the date of the loss.
Ask the installer or inspection body for a written statement on the type, installation, operation and certification. Have a clear distinction made between the current situation and the situation at the time of the loss. A system installed later does not prove that the old situation complied.
Also keep any questions you put to the insurer or adviser beforehand. If a different security arrangement was expressly accepted, that may be relevant. An unconfirmed assumption that a more expensive system “will surely be sufficient” carries less weight.
What Kifid says about clear security requirements
In Kifid 2025-0137, a claim following a car theft was rejected because the required security system was missing. Kifid, the Dutch Financial Services Complaints Tribunal, found that the requirement was stated sufficiently clearly on the clause sheet. In that case, the insurer was not additionally required to request the certificate in advance.
This example shows that the fact that the insurer did not carry out a check does not automatically mean that you met the requirement or were exempt from it. It remains important to check the policy documents you receive and to raise any ambiguities in good time.
The decision does not settle every security case. A different clause, a deviating assurance or unclear provision of the terms may lead to a different outcome. So compare the specific wording and facts, not merely the type of vehicle stolen or the name of the insurance.
Inspections such as SCOPE under a business insurance policy
Business property insurance may impose requirements concerning inspections of electrical installations or other risks. The policy may require a particular inspection, period and handling of defects. A report that lists defects is not automatically proof that all prevention conditions have been met.
Check who was responsible for the inspection: owner, tenant, property manager or business. An arrangement in a lease does not simply remove your own obligations towards the insurer. It may, however, be relevant to a separate claim against the party that was supposed to arrange the inspection.
Ask the expert which part of the installation was examined and whether the repairs were checked. The legal discussion must match the precise policy standard. Do not automatically apply the latest technical standard if the policy refers to another version or to a specific arrangement.
What if the insurer or adviser knew about the situation?
Did you send photos, reports or questions beforehand that clearly showed the deviation? Keep the full response. An express acceptance may be relevant to the interpretation or amendment of the agreement. Silence or a general acknowledgement of receipt does not automatically carry the same meaning.
Ask who was authorised to accept the deviation. An installer can advise on technical matters, but does not automatically decide on cover on behalf of the insurer. The role of an intermediary must also be established before their statement can be attributed to the insurer.
An objection must therefore make clear which assurance you received, from whom, and on what you subsequently relied. A summary written after the event carries less weight than an email setting out the specific deviation and its acceptance. Where possible, have oral arrangements reconstructed using the available documents.
Can the intermediary be liable?
An insurance intermediary must advise with due care and explain relevant clauses and their consequences appropriately. That does not mean that he must personally check every prevention measure on an ongoing basis. The instructions, known risks and information provided determine the scope of his duty of care.
In Kifid 2025-0398, the claim against the intermediary was rejected because sufficient information had been given about the security requirements. The consumer was also expected to check the documents received and to ask questions in case of doubt.
A rejection by the insurer therefore does not automatically prove an error by the adviser. Examine separately which warning was missing and whether, with correct information, you would have taken the required measure. That link is necessary for any claim for damages.
Using technical investigation in a targeted way
An expert can help establish whether an installation worked, whether an inspection was carried out correctly or whether a prevention measure would have made a difference. Formulate the investigation question together with the legal question. A report on the amount of the loss does not automatically answer a dispute about its cause.
Before instructing an expert, ask what work is needed, what it will cost and which items must remain available. Keep damaged parts where this is safe and practically possible. Coordinate necessary repairs so that evidence is not lost unnecessarily, without delaying necessary loss mitigation.
Reimbursement of expert costs cannot be taken for granted in every coverage dispute. The statutory rule on reasonable costs of assessing the loss must be distinguished from an investigation into whether cover exists. Read more about this under the loss adjuster and counter-assessment.
A fictitious example of the right investigation question
A business suffers fire damage and the insurer rejects the claim because an electrical inspection was missing. The business owner then only has the cost of repairing the building calculated. That report may substantiate the amount of the loss, but says nothing yet about the meaning of the inspection clause.
First it must be established whether the policy makes cover conditional on an inspection and which exceptions apply. If the link between the missing inspection and the fire is relevant, an expert must be asked about precisely that. The source of the fire may have been outside the installation, but that too must be substantiated.
This example shows why legal and technical investigation must be aligned. An expensive report on the wrong question will hardly move the discussion forward. So first ask for the full grounds for rejection and then decide what evidence is needed.
Building an objection to the rejection
Describe the loss, the policy and the disputed clause. Set out whether you argue that the requirement was met, that a deviation was accepted, that the provision should be interpreted differently or that an exception applies. Support each ground with appropriate documents.
Ask the insurer to respond to each argument separately. If the insurer cites several exclusions, these must also be assessed separately. Rebutting one reason does not automatically mean that the entire loss is covered.
Specify the outcome you are asking for: acknowledgement of cover, resumption of claims handling or payment of an agreed amount. An unclear claim can get stuck in a discussion about the extent of the loss while cover has not yet been decided.
Evidence and deadlines after the loss
Report the loss in good time and provide relevant information. A dispute about prevention does not automatically remove your duty to cooperate. If a request for information is unclear or too broad, ask for clarification and provide the information reasonably available in a targeted manner.
The limitation period and complaint deadlines must be monitored separately. An ongoing technical investigation does not automatically protect those deadlines. If necessary, confirm in writing that you maintain your claim and assess whether a valid act to interrupt the limitation period is needed.
For consumers, Kifid may be an option where the insurer or intermediary is affiliated and the complaint falls within its rules. For business insurance, access cannot be taken for granted. The court may then be the appropriate route, or another procedural option may be chosen.
Turn the technical discussion into a verifiable comparison
A rejection based on a prevention clause sometimes contains several technical allegations. The installation allegedly did not comply, maintenance was allegedly lacking and a certificate had allegedly expired. Deal with these points separately. Set against each allegation the exact policy passage, the situation before the loss and the available evidence. This shows whether the insurer is mixing up different requirements or is in fact identifying three separate obligations.
Do not just ask an installer or expert whether the installation was in good order. Have them explain which standard or design was examined, which components were present and what the limitations of the investigation are. An inspection after repair cannot always show how the system functioned on the date of the loss. Old maintenance reports, fault reports and invoices may therefore be more important than a general positive opinion after the event.
Also pay attention to changes in the meantime. Was the building renovated, did a new tenant move in or did the storage change? Examine which change is relevant to the insured situation and what was reported about it to the insurer or adviser. An existing insurance policy does not mean that every new business activity is automatically covered by the same arrangements.
The aim of this comparison is not to meet a requirement retrospectively, but to establish which requirement applied and whether reliance on it is justified. For a major technical investigation, agree in advance which legal question the report should help answer. That avoids costs for conclusions that do not touch the actual coverage dispute. An expert can assess technical facts; the interpretation and application of the policy remain legal questions as well.
Linking the prevention clause to the loss
Ask which specific security or maintenance obligation was breached and how the clause limits cover. An inspection requirement, an alarm condition and a storage rule may be worded differently in legal terms. The significance of a link with the loss depends in part on the clause and the applicable rules.
Record certificates, checks, maintenance and fault reports. A missing document is not automatically the same as a measure that was not taken. Ask the insurer to separate its factual and legal reasoning.

Frequently asked questions about prevention clauses
May the insurer reject my claim even though I did have an alarm?
That depends on the agreed requirement and the actual security in place. A system that is present does not automatically meet every class, certification or condition of use. Ask which element is missing and compare that with the installation and maintenance records.
Is there always cover if the missing measure had nothing to do with the loss?
No. The importance of causation depends on the clause and its legal characterisation. Sometimes the policy contains an express exception; sometimes it concerns the definition of the scope of cover. Have that assessed first.
Should the insurer have requested my certificate in advance?
That is not a general obligation in every case. A clear policy condition may entail your own responsibility. Do, however, examine any arrangements or assurances and whether the requirement was communicated sufficiently clearly.
Does an inspection report always mean I have met the obligation?
Not necessarily. The policy may also require defects to be remedied or an inspection to cover a specific component. Read the full requirement and ask the expert to confirm what was actually checked.
Will the insurer pay for my technical counter-investigation?
Not automatically in a coverage dispute. Ask about the legal basis in advance and make clear agreements on costs. Reasonable costs of assessing the loss and of investigating whether cover exists at all may be treated differently in law.
