How do ancillary costs break down?

Ancillary costs are costs for services provided by the landlord or third parties that are connected with the use of the rental property (Art. 257a (1) Swiss Code of Obligations (SCO)). Only costs that have actually been incurred may be charged (Art. 257b (1) SCO). This means that the statement of ancillary costs cannot be a source of profit for the landlord.

Important: ancillary costs must only be paid if they are expressly and individually listed in the rental agreement (Art. 257a (2) SCO). In the absence of such an agreement, the ancillary costs are deemed to be included in the rent. Collective items such as “other operating costs” are not enough.

Costs and public charges associated with the property itself, on the other hand, are borne by the landlord (Art. 256b SCO). Consumption-based charges such as water or garbage can only be charged if this has been agreed in the rental agreement.

Overview of ancillary costs for rental properties

Billable ancillary costs Non-billable ancillary costs
Heating and hot water Repair and maintenance work (e.g. heating boilers, painting of staircases)
Water and sewage (consumption-based charges) Property taxes
General electricity (e.g. staircase, laundry room) Building insurance premiums
Maintenance (excluding repairs and maintenance) Value-related basic fees
TV basic usage fees (e.g. cable connection) General management of the property
Elevator including service contract  
Management fee (only for ancillary costs)  

For the preparation of the statement of ancillary costs, the landlord may charge an administration fee, either based on actual expenditure or as a flat rate (Art. 4 (3) ORLOCP). The admissible amount is governed by cantonal law: the tenant association considers 2 to 3 percent of the total ancillary costs to be the upper limit, while some in theory and practice consider up to 5 percent to be admissible. If invoices are based on actual time spent, a higher amount is also possible, provided it is documented. However, the flat rate may only cover the cost of managing ancillary costs. The general management of the property, on the other hand, is the responsibility of the landlord.

A useful basis for checking statements of ancillary costs is the tenant association’s detailed list of admissible and inadmissible items (in German). It provides a good basis, but the details are contentious, particularly with regard to the rates for the management fee.

Why do I receive a statement of ancillary costs?

You will receive a statement of ancillary costs because various items are listed as ancillary costs in your rental agreement, which you must pay in addition to the net rent.

As a rule, a distinction is made between lump sum payments and payments on account.

  • Lump sum payment: you pay a fixed amount. This covers ancillary costs, even if the actual costs are higher or lower.
  • Payment on account: in your annual statement, you will receive a credit if the actual heating and ancillary costs are less than the amount paid in advance. If the actual costs are higher than your payment on account, you will have to make a back payment.

Below, we show you step-by-step how to check your statement of ancillary costs.

Legal protection as a tenant

What do “operating costs” mean in the rental agreement?

Unclear terms such as “operating costs” are not permitted in a rental agreement; they must be specified in detail. A reference to general contractual conditions is also not permitted. For you as a tenant, it must be clear which ancillary costs you will have to pay in addition to the rent.

When do I have to make ancillary cost back payments?

If the actual heating and ancillary costs exceed the total payments made on account, you normally have to make a back payment.

If your total payments on account exceed the actual costs, you will receive a refund from your landlord – or the corresponding amount will be credited to your next annual statement. Before you transfer the amount, it’s worth checking the statement of ancillary costs.

You won't receive a statement if your heating and ancillary costs are already included in your rent or if you settle these costs by way of a lump sum payment.

In general, it’s advisable to agree a sufficiently high payment on account when concluding the rental agreement. In this way, you can avoid having to make substantial back payments.

“If something is unclear with the statement of ancillary costs, try talking to your landlord first: he or she will certainly let you see the receipts on which the statement is based. In this way, questions or misunderstandings can often be resolved directly and simply.”

Check statement of ancillary costs in six steps

If you receive a bill for heating and ancillary costs, it’s worth taking a close look at it. To review your annual statement of heating and ancillary costs, it’s best to proceed gradually:

  1. Check whether the billed positions are explicitly listed in your rental contract as ancillary costs: you only have to pay those ancillary costs that are expressly agreed in the rental agreement and are thus shown.
  2. Check the details for each position: you only have to pay the costs incurred by use. Repair and maintenance work (replacement of the heating boiler, repainting of the staircase, etc.) does not count as ancillary costs and may not be passed on to the tenants.
  3. Check the allocation formula: heating and ancillary costs must be allocated to all rental properties in a property using a transparent formula. The type of allocation formula is not specified by law; however, it may not be changed without a formal amendment to the rental contract.
  4. Check the arithmetic of the statement of heating and ancillary costs and compare your total payments on account with the amount you’ve been charged.
  5. Ask to see the documentation if the details provided by the landlord on the statement of ancillary costs are inadequate for you. This allows you to check the costs behind the individual positions. “General operating costs” must be broken down by the landlord on request.
  6. Ask for the statement to be corrected if you discover an error. In the event of a dispute, engage the support of an expert but only after you talk to your landlord.

How can I contest my statement of ancillary costs?

If you’ve checked your statement and discovered an error, the best thing to do is as follows:

  • Ask to speak to your landlord: contact your landlord first and mention the mistake.
  • Ask for it to be corrected: then ask for the correction in writing, ideally by registered mail.
  • Involve the mediation authority: if no agreement can be reached, you can contest the statement with the arbitration office.

Time limits and statute of limitations

There is no legal deadline for disputing the statement. However, the landlord’s entitlement to payment of ancillary costs lapses after five years – calculated from the end of the billing period concerned or from the date when you move out of the apartment. Conversely, tenants can reclaim any overpaid ancillary costs. Depending on the type of claim for recovery, different limitation periods apply: three years from the date of knowledge of the claim or ten years from the date of its creation.

If the landlord refuses to allow inspection of the documents, then any subsequent claim for an agreed payment on account will not be settled. Payment is only required if the claim is duly substantiated and documented.

Costs of arbitration proceedings

As a rule, there are no court fees for arbitration proceedings in rental matters. Legal expenses are not awarded to the opposing party either (Art. 113 Swiss Civil Procedure Code (CPC)). You pay your own expenses, such as for legal representation. However, costs can be imposed in the case of malicious prosecution (Art. 115 CPC).

Important: you must appear in person. If you’re unsure, have your statement of ancillary costs checked by an expert in tenancy law.

Even better: if you take out tenant legal protection early on, you’ll be on the safe side. It covers lawyers’ and court fees and offers an assessment in advance of whether it’s worth contesting. Only those who take out coverage before a dispute arises can be insured.

Frequently asked questions about “Check statement of ancillary costs”

Do I have to pay ancillary costs that are not listed in the rental agreement?

No, you only have to pay ancillary costs if they are expressly agreed in the rental agreement. In the absence of such an agreement, the rent shall be deemed to have been paid. Lump sum or badly worded items are not enough.

How much time do I have to check the statement of ancillary costs?

There is no statutory deadline for reviewing and filing complaints. You have the right to view the detailed statement and receipts at any time, regardless of what is stated in the rental agreement.

How long can ancillary costs be claimed in Switzerland?

Claims made by a landlord for ancillary costs become time-barred after five years – calculated from the end of the relevant billing period or from the date you move out. If you only receive a statement after that, you no longer have to pay it. Conversely, you can reclaim any excess ancillary costs you have paid: depending on the type of entitlement, within three years of becoming aware of them or ten years after they were incurred.

What are the average ancillary costs per month?

As a rule of thumb, ancillary costs are around 15 to 25 percent of the net rent. However, the actual amount depends very much on the size of your apartment, the type of heating, the building standard, and the region in which you live. Heating costs account for the largest share.
