Service Charges: Flat Fee or Provisions?
The Two Systems
| Criterion | Flat Fee | Provisions + Settlement |
|---|---|---|
| Principle | Fixed monthly amount | Monthly advance + annual adjustment |
| Settlement | None | Mandatory (annual) |
| Landlord risk | Underestimation of costs | None (actual costs recovered) |
| Tenant risk | Overestimation | None (only pays actual costs) |
| Simplicity | ✅ Very simple | ❌ Accounting required |
| Fairness | ❌ Approximate | ✅ Based on actual costs |
| Indexation | Indexable with the rent | Not indexable (based on actual costs) |
Recoverable vs Non-Recoverable Charges
| ✅ Recoverable (tenant's responsibility) | ❌ Non-recoverable (landlord's responsibility) |
|---|---|
| Water (consumption) | Property tax |
| Collective heating | Building insurance |
| Common area maintenance | Major repairs (roof, facade) |
| Elevator (maintenance + electricity) | Management/syndic fees (professional fees) |
| Waste collection | Collective boiler replacement |
| Common area electricity | Facade renovation |
| Common garden maintenance | Compliance upgrades (fire, elevator) |
| Chimney sweeping |
How to Set the Flat Fee Amount?
- Calculate your actual costs over the last 12 months (water, energy, syndic invoices)
- Divide by 12 to get the average monthly charge
- Add a margin of 10-15% for unexpected expenses
- Reassess each year — the flat fee can be indexed with the rent
How to Manage Provisions with Settlement?
Landlord's Obligations
- Set a reasonable monthly provision (based on the previous year's costs)
- Keep accounts of actual charges
- Provide a detailed annual settlement to the tenant
- Make supporting documents available (invoices, syndic statements)
- 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

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
