Syndic fees: how to read, compare and renegotiate them
Your syndic's fees seem heavy, but the 'flat fee' line does not tell the whole story. Here is how to add up the real cost, compare quotes on a fair basis and renegotiate the contract.

Article 3.89, § 1, of the Civil Code, The syndic
“That contract includes in particular the list of services covered by the flat fee and the list of additional services and the fees attached to them. A service not mentioned cannot give rise to remuneration except by decision of the general meeting.”Read the text ↗
- Work out the real costAdd up the flat fee and all the additional services invoiced over the last two financial years.
- Reread the contractCompare each invoiced service with the list in the contract and spot those that are not in it.
- Draw up specificationsDescribe the building and the services expected so that you get comparable quotes.
- Consult several syndicsAsk for at least three quotes on the same basis, including from the current syndic.
- Decide at the general meetingPresent the comparison table to the general meeting before the mandate expires.
Art. 3.89, § 1, Civil CodeArt. 3.89, § 1, Civil CodeArt. 3.88, § 1, 1°, Civil CodeYou are rereading the annual statement, and someone asks at the general meeting (GM): "How much does the syndic really cost us?" Nobody has the exact answer. Syndic fees often appear in two stages: a "flat fee" line that hardly moves, then a series of amounts scattered across administrative costs. What counts is the sum of the two.
Our view: reducing the fees of a property manager (syndic) starts with that addition, before any discussion of price. Only then come comparing quotes and renegotiating, using the levers the law gives you. For orders of magnitude and the factors that make the price vary from one building to another, see the page on syndic prices in Belgium.
How are a syndic's fees structured?
Everything starts with the contract. The Civil Code requires a written contract between the syndic and the owners' association (VME/ACP), and it sets its minimum content:
“That contract includes in particular the list of services covered by the flat fee and the list of additional services and the fees attached to them. A service not mentioned cannot give rise to remuneration except by decision of the general meeting.”Art. 3.89, § 1, Civil Code
So three blocks appear in almost every contract.
The base flat fee
It covers day-to-day management: bookkeeping, calls for funds, paying suppliers, organising the ordinary general meeting, following up maintenance contracts, routine management of the common parts. It is often expressed per unit or per building, per month or per year. What exactly is included varies a great deal from one contract to another: two identical flat fees can cover very different services.
Additional services
Everything outside day-to-day management: extraordinary general meetings, extra meetings of the co-ownership councilGlossaryBody made up of co-owners, mandatory in buildings with at least twenty units, excluding cellars, garages and parking spaces. It ensures that the syndic carries out their duties properly. See the glossary, supervision of major works, handling claims, debt recovery files, preparing grant applications, travel outside office hours. They are billed by the hour, per task or as a percentage of the cost of works. The law requires them to be listed with their fees.
Private costs
Some services concern a single co-owner and must be charged to him, not to the collective. The best-known example is the sale of a unit: the costs of providing information to the notary are borne by the outgoing co-owner, and the notary withholds them from the price (Article 3.95 of the Civil Code). Reminder and recovery costs follow the same logic where the contract and the articles provide for them. Check that these amounts do not slip into the common charges.
A professional syndic must be registered with the Professional Institute of Real Estate Agents (BIV/IPI). His fees are subject to VAT, which matters when comparing with a quote presented excluding VAT.
Why is comparing flat fees not enough?
Because the lowest flat fee can become the most expensive as soon as something happens in the building: a claim, a façade project, an extraordinary meeting. The only reliable comparison is the total annual cost for your building, calculated over a typical year.
To build this calculation, take the last two or three financial years and note what actually happened: number of meetings, works supervised, claims, units sold. Then ask each candidate to price that same scenario. The following table serves as a template.
| Item | Syndic A | Syndic B | Syndic C |
|---|---|---|---|
| Annual flat fee, VAT included | |||
| Ordinary GM (included or not) | |||
| Extraordinary GM, per meeting | |||
| Supervision of works (calculation method) | |||
| Handling a claim | |||
| Recharged administrative costs | |||
| Total cost of the typical year |
Alongside it, add the factors that cannot be priced but weigh on quality: stated response time, online access to documents, number of buildings per manager, physical attendance at meetings, professional liability insurance.

Competitive tendering: what the law requires and what it allows
The general meeting decides by a two-thirds majority of the votes the amount of contracts above which competitive tenderingGlossaryObligation to compare several offers for contracts above the threshold set by the general meeting by a two-thirds majority. The syndic must then present several quotes. See the glossary is compulsory (Article 3.88, § 1, 1°, c), of the Civil Code). For contracts subject to such tendering, the syndic must "present several cost estimates, based on previously drawn-up specifications" (Article 3.89, § 5, 11°, of the Civil Code). If your co-ownership has never voted on this threshold, put the point on the agenda: it is a tool for controlling costs, for suppliers and service providers alike.
The syndic must also submit each year to the ordinary general meeting an evaluation report on contracts for regular supplies. That report is the right moment to raise the question of maintenance, insurance and energy contracts, which sometimes weigh more than the fees themselves. Any contract between the association and the syndic, his staff or his relatives also requires the general meeting's prior authorisation.
For the syndic's own contract, the timetable is dictated by the length of the mandate. It cannot exceed three years and is only renewed by express decision of the general meeting. The mere fact of not renewing the mandate cannot give rise to any compensation. Consulting several syndics before each expiry date, on the basis of specifications, is therefore the simplest way to test the market price. The typical content of the contract is set out in the page syndic contract.
Which levers can you use to renegotiate the current syndic's fees?
Changing syndic is not always desirable. A syndic who knows the building, its suppliers and its history has real value. We say it from the outset: renegotiation is often the best option, provided you come with concrete evidence.
- Challenge services outside the contract. Any remuneration not provided for in the contract and not voted by the general meeting can be refused. Point it out in writing and ask for a refund.
- Widen the flat fee: offer to include one extraordinary meeting a year, or the handling of small claims, in the flat fee in exchange for a stable overall price.
- Cap percentages on works. An uncapped percentage on a large project produces fees bearing no relation to the work done. A fixed fee per phase or a cap can be negotiated.
- Lighten the syndic's workload. An active co-ownership council, co-owners who accept notices by email, documents shared online: every task removed is an argument.
- Set competing quotes side by side. Presenting the general meeting with a comparison table based on the typical year changes the nature of the discussion.
The agreement reached must be recorded in an amendment or a new contract, approved by the general meeting. If the negotiation fails, the procedure is described in the page changing your syndic, and the wider question of switching to a volunteer syndic is covered in the page on the volunteer syndic.
Finally, fees fit within the overall annual budget and are checked each year in the service charge statement. The full overview of the building's finances is on the page co-ownership service charges.
Do, avoid
- Demand the priced list of services outside the flat fee
- Compare quotes on total annual cost, VAT included
- Prepare the negotiation before the end of the mandate
- Check who pays the private costs that are recharged
- Comparing flat fees without reading what they cover
- Paying for a service not in the contract without a GM decision
- Signing a contract that runs beyond the mandate
- Choosing on price alone, without checking BIV/IPI registration
Where fees most often get out of hand
| Item | Finding | What to check |
|---|---|---|
| Extraordinary general meetings | Each extra meeting is invoiced while the contract does not say how many meetings the flat fee covers | The price per meeting and the number of meetings included in the flat fee |
| Supervision of works | Fees are calculated as a percentage of the project, with no cap or written trigger threshold | The calculation method, the trigger threshold and whether there is a cap |
| Administrative costs (copies, postage) | Copies, postage and file fees are recharged with no list or unit price in the contract | The list of rechargeable costs and their unit price |
| Claims and insurance files | Handling the file is billed by the hour although the hourly rate is not in the contract | The hourly rate or price per file written into the syndic contract |
Frequently asked questions
Can the syndic charge for a service that is not in his contract?
No, unless the general meeting decides otherwise. The Civil Code provides that a service not mentioned in the contract cannot give rise to remuneration. You can ask the syndic to justify each line and, if need be, refuse to approve the accounts on that point.
Is there an official scale of syndic fees?
No. The Professional Institute of Real Estate Agents (BIV/IPI) states that there are no recommended or compulsory rates. Each syndic sets his remuneration freely, and it must be clearly stated in a written agreement.
Can fees be renegotiated during the mandate?
Yes, by agreement with the syndic, recorded in an amendment approved by the general meeting. The best moment remains the end of the mandate, which cannot exceed three years: not renewing it gives rise to no compensation.
Are the costs charged to the seller of an apartment borne by the co-ownership?
No. The costs of providing the information required when a unit is sold are borne by the outgoing co-owner, and the notary withholds them from the price. They must not appear in the common charges.
