Two cases, two lists
The CIL does not have the same contents depending on whether it is created at construction or on the occasion of renovation works with an energy impact. In both cases, the documents attesting energy performance are added.
Case 1: new build (permit or prior declaration filed since 1 January 2023)
| Element | Details |
|---|---|
| Surface plans and cross-sections | The home as built, not as drawn at the design stage. |
| Network plans / diagrams | Water, electricity, gas, ventilation: their real location. The most valuable information in the logbook day to day (drilling a wall, tracing a leak). |
| Thermal insulation materials | For each of the 4 categories of insulated walls (roof, external walls, glazed surfaces and external doors, ground floors): material, brand and reference, thermal characteristics (thickness, R-value), surfaces (order of 27 December 2022, art. 7). |
| Equipment instructions | Operation, maintenance and servicing of the heating, cooling, ventilation and hot-water systems. |
These elements must be handed to you by the builder at the latest at acceptance: see CIL and new builds.
Case 2: renovation with an energy impact (since 1 January 2023)
| Element | Details |
|---|---|
| Description of the works | Precise nature of the job (which wall, which equipment replaced), date carried out. |
| Installed materials and equipment | Technical characteristics: insulation installed (material, thickness, R-value, surface), equipment installed (type, brand, model, energy source, power). |
| Associated instructions | Operation, maintenance and servicing of the installed equipment. |
The company carrying out the works must hand this information to the owner at the latest at acceptance (who does what on the CIL). The list of covered works is detailed in which works trigger the CIL.
In all cases: energy performance
- DPE in force where one exists;
- energy audit where applicable;
- any document tracking the evolution of the home's performance after works;
- attestation of compliance with thermal or environmental regulations, drawn up by the project owner where required;
- attestations of energy performance labels or certifications, where applicable (art. R. 126-34 of the CCH).
Not mandatory, but worth adding anyway
The regulatory CIL is a minimum. A logbook genuinely useful at resale or day to day also contains:
- Invoices and quotes for all works, energy-related or not: they date, price and prove;
- servicing certificates (boiler, chimney sweeping, heat pump, ventilation);
- warranties and acceptance reports (parfait achèvement, biennale, décennale);
- dated photos before/during/after works, unbeatable in a dispute or a claim;
- previous surveys: the history of DPE certificates tells the story of the home's improvement.
The Relai Confiance logbook ships with the structured list of documents to keep (plans, surveys, instructions, warranties) and tracks what is missing. The property's health score updates with every addition.
