What the administration may verify
Four elements, corresponding to the conditions of grant. They are the subject of after-the-event checks.
Actual use of the dwelling, which may be verified through residence registration data and other elements.
Eligibility of the works invoiced at the reduced rate, measured against the description on which approval was based.
Observance of the ceiling, across all works on the dwelling.
Maintenance of the use for the period required.
The third point deserves attention: it is the one that reveals overruns on dwellings that have undergone earlier works, as the article on the ceiling and its exhaustion explains.
| Item checked | Document expected | Consequence if missing |
|---|---|---|
| Actual occupation | Proof of residence | Repayment possible |
| Nature of the works | Detailed invoices | The rate is called into question |
| Use of the dwelling | Declarations and deeds | Repayment possible |
| Compliance with deadlines | Dates of applications and invoices | Loss of the benefit |
The documents it may request
An expressly provided point.
The administration may request the production of additional documents, at any stage of the procedure.
The documents usually at issue are invoices, evidence of payment, documents relating to the dwelling and material establishing use.
This power applies after the grant too, and not only during processing.
Keeping documents throughout the commitment period and beyond is therefore a practical necessity, not an excessive precaution.
The cases of repayment
Three situations, flowing from the undertakings given. They trigger repayment of the benefit.
The use was not realised, or was not maintained for the period required.
The eligibility conditions were not met, which may emerge on a later check.
The ceiling was exceeded, notably through earlier works not taken into account.
The beneficiary expressly undertakes to repay any sum unduly received, an undertaking contained in the declaration accompanying the application.
Repayment may therefore arise long after the works, which justifies documented tracking.
How to respond to a check
Four points.
Reply within the periods stated, silence aggravating the position.
Produce the documents requested, rather than explanations.
Document the circumstances where a breach is found, particularly if it results from an event outside your control.
Do not regularise unilaterally without having checked how the situation is classified with the administration.
What genuinely protects
Three practices, more effective than any later argument. They consist in documenting as things happen.
Having declared changes within the periods, which distinguishes a difficulty from a breach.
Having kept the supporting documents, notably those establishing use.
Having checked the ceiling available before the works, which removes the risk of overrun.
These three practices cost nothing when put in place, and they are decisive when a check occurs.
What this means for a professional
Four rules.
Recall that the power of verification is exercised after the grant, and not only during processing.
Recommend keeping documents beyond the commitment period.
Check the ceiling before the works, the only protection against an overrun revealed late.
Direct people to the administration where a breach is found, rather than to an improvised regularisation.
