Version 1.8 of the Model Commercial Lease was launched on 4 April 2025. To assist users in identifying the changes made in the new versions of the documents, we have prepared a detailed list of the changes and a red-line version of the lease of an office in part of a building (MCL-OFFICE-02) that you can download from the following links.
This version of the MCL includes a number of changes based on the latest edition of the Better Buildings Partnership Green Lease Toolkit. A separate guidance note available below sets out the approach that we have taken in relation to the new provisions.
