Mandatory mentions on a construction quote (2026 list)

A construction quote is a legal document. If a mandatory mention is missing, it can be deemed non-compliant — and a missing mention can cost up to €1,500 in fines (source: economie.gouv.fr).

Depending on the level of detail, there are 15 to 18 mentions. Here is the complete list, by category, up to date for 2026 — with a PDF checklist to print out.

The 4 categories of mentions

General mentions (the quote itself)
Your company
The client
The offer (the works and their price)

1. General mentions

The word "Devis"
The date of issue
The validity period (without it, you remain bound by the price indefinitely)
Whether the quote is free or paid

2. Your company

Company name and legal form (auto-entrepreneur, sole trader, limited company, etc.)
Address and contact details (phone, e-mail)
SIRET number
Registration with the Répertoire des métiers (RM) (Trades Directory) or the RCS (Trade and Companies Register)
Intra-EU VAT number (or the mention "TVA non applicable, art. 293 B du CGI" under the VAT exemption)
Assurance décennale (ten-year liability insurance): insurer and geographical zone covered — required by the loi Spinetta (the Spinetta Act)

3. The client

The client's name / company name and address
The place where the works are carried out (if different)

4. The offer (works and price)

A detailed description of each service: materials (brand/reference), quantities, unit prices excl. VAT, labour
The total excl. VAT, the VAT rate and amount (20 / 10 / 5.5 %), the total incl. VAT
Any travel costs
The mention on waste management (mandatory since 1 July 2021 for construction, renovation or demolition): estimated quantities, removal arrangements, collection points and costs

The handwritten mention and the signature

The quote becomes a contract as soon as it is signed, together with the handwritten mention:

"Devis reçu avant l'exécution des travaux — Bon pour accord" (Quote received before the works are carried out — Approved for agreement), dated and signed by the client.

To this are added the payment terms (deposit, payment schedule, late-payment penalties) and, for a private client, information about the consumer mediator (médiateur de la consommation).

Penalties for omissions

A missing mandatory mention exposes you to a fine of up to €1,500 — not to mention the risk of a dispute with the client. Compliance is not optional.
