How to Set the Flat Fee Amount?

  1. Calculate your actual costs over the last 12 months (water, energy, syndic invoices)
  2. Divide by 12 to get the average monthly charge
  3. Add a margin of 10-15% for unexpected expenses
  4. Reassess each year — the flat fee can be indexed with the rent

How to Manage Provisions with Settlement?

Landlord's Obligations

  1. Set a reasonable monthly provision (based on the previous year's costs)
  2. Keep accounts of actual charges
  3. Provide a detailed annual settlement to the tenant
  4. Make supporting documents available (invoices, syndic statements)
  5. Settle: reimburse any overpayment or invoice the shortfall

Settlement Deadline

The settlement must be provided within a reasonable timeframe after the end of the accounting period (in practice, within 2-3 months). The tenant has the right to contest within 2 months of receipt.

Regional Specificities

BBrussels

  • The lease must specify the chosen system (flat fee or provisions)
  • With provisions, the landlord must provide the settlement and supporting documents
  • The tenant can request conversion from flat fee to provisions (and vice versa) at each triennial period
  • Bruxelles Logement — Charges

WWallonia

  • Same principles as Brussels
  • The Walloon decree requires transparency on charges
  • SPW Logement

VFlanders

  • The Flemish decree regulates charges in a similar manner
  • The landlord must be able to justify each charge item
  • Woninghuur Vlaanderen

Common Mistakes

  • Not specifying the system in the lease — in the absence of specification, the flat fee applies by default
  • Flat fee too low — you cannot claim the difference from the tenant
  • No annual settlement (provisions) — the tenant can demand reimbursement of all provisions
  • Mixing recoverable and non-recoverable charges — property tax is NEVER the tenant's responsibility
