BT01 2022 – National Building Index (all trades)

The BT01 2022 index is France’s national construction index (all trades).

It measures changes in the cost of factors of production in the building industry and is the official reference for updating and revising construction contract prices.

The Index was created by a decree published in the Official Journal on December 20, 2014 (base 100 = 2010 average) and is published monthly by INSEE. It thus succeeds the Index of Building and Public Works (bases 1974 and 1975), which has been discontinued.

Use of the BT01 2022 index:

Rule:

The price of the service of the contract of services will be revised at each expiry of the agreement according to a formula that integrates the evolution of the BT01 Index.

Formula:

[New price] = [old price] X [Known reference index BT01] / [Reference index BT01]

Attention, do not confuse the BT01 Index with the “Construction Index” or the “Rent Reference Index“, used respectively to revise rents for private individuals and leases for professionals. The values in this table will be updated at the rate of the publication of the Index during the year 2022.
