Since October 1, 2023, the EPC-related restrictions on rent indexation have been lifted in the Flemish Region. This means that rents in Flanders may be re-indexed regardless of the energy performance of the property, as previously prescribed. Nevertheless, a modified calculation method, including a correction factor, has been introduced for properties with an EPC label D, E, F or for properties without a valid EPC certificate. This measure is designed to prevent landlords from fully reclaiming revenue from missed indexations. <\/p>\n

Before Oct. 1, 2023, rent indexation in Flanders was directly linked to the home’s EPC certificate. The former rules were as follows: <\/p>\n
These restrictions were lifted effective Oct. 1, 2023.<\/p>\n
The revised method of rent indexation in Flanders takes into account the rent excluding costs, the health index and a specific correction factor. The correction factor depends on the property’s EPC label and the anniversary of the lease. <\/p>\n
The general formula is:<\/p>\n
New indexed rent = New indexed rent without restriction x Correction Factor<\/strong><\/p>\n The “new indexed rent without restriction” is calculated as follows:<\/p>\n New indexed rent without restriction = (Base rent x New index) \/ Base index<\/strong><\/p>\n You can access the latest health indexes through a current index table.<\/p>\n <\/strong><\/p>\n Indexing with the adjusted formula (correction factor) can be applied if:<\/p>\n These features are consistent with the conditions that applied during the rent freeze until Sept. 30, 2023.<\/p>\n Below is a detailed overview of correction factors depending on the EPC label and contract anniversary:<\/p>\n Lease anniversary between 01\/10\/2022 and 31\/12\/2022<\/p>\n<\/td>\n Anniversary of lease between 01\/01\/2023 and 30\/09\/2023<\/p>\n<\/td>\n<\/tr>\n<\/thead>\n EPC D<\/strong><\/p>\n<\/td>\n 0.5 x [(index 2021 + index 2022) \/ index 2022]<\/p>\n<\/td>\n 0.5 x [(index 2022 + index 2023) \/ index 2023]<\/p>\n<\/td>\n<\/tr>\n EPC E, F or unknown<\/strong><\/p>\n<\/td>\n Index 2021 \/ index 2022<\/p>\n<\/td>\n Index 2022 \/ index 2023<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n Exporting to Spreadsheets<\/p>\n Explanation:<\/em><\/p>\n <\/strong><\/p>\n Suppose:<\/p>\n Step 1: Calculate the indexed rent without restriction<\/strong><\/p>\n Step 2: Calculate the correction factor and adjusted rent<\/strong><\/p>\n In this example, the owner can charge \u20ac564.44 per month (excluding fees) as new rent.<\/p>\n <\/strong><\/p>\n In Flanders, as in the rest of Belgium, rent can be indexed up to once a year on the anniversary of the lease. The landlord must notify the tenant in writing of the indexation, including the calculation and the new rent amount. Without this notification, the tenant is not obliged to automatically adjust the rent. <\/p>\n If the landlord is negligent, the indexation can be corrected retroactively for up to three months.<\/p>\n To avoid forgetting indexations and avoid calculation errors, property management programs can help. Software such as Offimac can notify landlords as soon as a lease is indexable. These tools perform the calculations automatically, taking into account factors such as the EPC label, the type of lease, the region and applicable legislation. In addition, notifications to the tenant (via email, letter or registered mail) can be generated and sent automatically, significantly streamlining the management process. <\/p>\n
