The work inspection (or construction site audit) for insulation projects is not billed directly to the homeowner. The cost, which generally ranges between €320 and €400, excluding tax, is paid in full by the RGE-certified contractor (Reconnu Garant de l’Environnement) to the certifying body conducting the audit (such as Qualibat or Certibat). [1, 2, 3, 4]
This inspection is mandatory for the contractor to maintain their RGE certification. The government conducts random inspections on certain job sites to verify that the work complies with standards and to release general financial assistance (such as MaPrimeRénov’ or CEE grants). [1, 2, 3]
To receive reimbursement for your insulation work with no hidden costs, here are the two applicable inspection/monitoring fees:
1. The Mandatory Energy Audit (Before Work Begins)
If you’re undertaking a major renovation to qualify for ANAH grants, an initial audit is required to quantify the energy savings. [1, 2, 3]
- Cost: Generally between €800 and €1,500.
- Coverage: This cost may be partially covered by government grants depending on your income. [1]
2. Support from “Mon Accompagnateur Rénov’” (MAR)
For major renovation projects, the ministry requires oversight by an approved, trusted third party. [1]
- Cost: Generally €2,000 to €4,000.
- Cost coverage: The government funds this mandatory service up to 100% for very low-income households (the out-of-pocket cost varies depending on your income).
