The official template: free, but optional

To accompany the entry into force of the carnet d'information du logement on 1 January 2023, the French ministry for ecological transition published an owner's guide and an official template downloadable as a PDF. Two things to know:

  • The CIL format is free. The law (articles L. 126-35-2 and following of the CCH) imposes contents, not a form. Paper, binder, spreadsheet, application: anything works as long as the sections are there.
  • The official template is a starting point, not an end. It is a static document: with every new quote, invoice or equipment replacement, re-editing it is on you.

The sections of a complete CIL template

Whatever the medium, a well-built CIL covers six sections:

SectionWhat goes in it
1. Identification of the homeAddress, type (house, flat), year built, living area, owner, DPE rating.
2. Plans and networksSurface plans and cross-sections; plans or diagrams of the water, electricity, gas and ventilation networks, as they exist after construction or works.
3. Thermal insulationFor each insulated wall (loft, walls, ground floor, windows and doors): material, thermal characteristics (thickness, R-value), surface, year installed.
4. EquipmentHeating, hot water, ventilation, cooling: type, brand and model, energy source, year installed, operating and servicing instructions.
5. Works carried outNature, company, year, amount; related quotes and invoices, especially for works with an energy impact.
6. Attached documentsDPE and energy audit, instructions, servicing certificates, warranties, acceptance reports.

Sections 2 to 4 and 6 correspond to the regulatory contents of the CIL; the detailed identification (section 1) and the amounts of the works (section 5) are good practice rather than a legal requirement. The exact regulatory list varies depending on whether the logbook is created at construction or during works: the detail is in our article mandatory CIL contents.

Build your template in 10 minutes: the free generator

Rather than starting from a blank PDF, our free CIL generator asks the right questions (home, insulation, equipment, works, documents) and produces a printable PDF logbook structured along the sections above. No sign-up, no data sent to any server.

Field advice. Do not aim for the perfect logbook on day one. Start with what you have at hand (DPE, latest boiler invoice, insulation quote), then complete it over time. A CIL that exists at 70 per cent beats a perfect CIL that never leaves the planning stage.

Paper template, spreadsheet or digital logbook?

  • Paper / static PDF: enough for a home with no works planned. Limits: every update is a manual re-edit, and the binder gets lost at the back of a cupboard (or in a move).
  • Spreadsheet: more flexible, but the attachments (instructions, invoices) live elsewhere, and nobody but you can find their way around it.
  • Digital logbook: continuous updates, attachments in one place, read-only sharing with the notaire or the buyer at sale time.
The template that fills itself in

In the Relai Confiance logbook, import any quote or invoice as a PDF: the app reads the document, extracts the date, company, nature of the works and amount, and updates your CIL. One-click PDF export.
