The concession creates obligations. The surety bond backs them up.
When the Administration grants a concession, it does not give away a free right: it demands commitments. The concessionaire must guarantee compliance with its obligations throughout the life of the concession, from the start of the works to the final handover of the installations.

Guarantees arranged quickly, without affecting your financial strength
Surety bonds allow guarantees to be issued quickly, without affecting your banking capacity or tying up capital. They are accepted by all public authorities as an equivalent to bank guarantees.
A concession is an administrative act by which a public authority grants an individual or company the right to use public assets or manage a public service for a defined period, subject to previously established conditions and obligations.
The key point is that ownership always remains with the State — only the right of use or operation is granted.

Types of Concession
Public Domain Concession
The concessionaire obtains the right to use or operate an asset belonging to the public: a beach, the subsoil, a radio frequency, a body of water.
Public Service Concession
The concessionaire manages a service that falls under public authority responsibility: a toll motorway, a port, an airport, drinking water supply, urban transport. The concessionaire assumes operational risk but acts under the framework and oversight of the public authority.

Reversion and Decommissioning: two distinct obligations
At the end of every concession, a final obligation arises towards the public authority. However, it is not always the same: depending on the type of concession and the terms set out in the tender specifications, the concessionaire must either hand over what has been built, remove it entirely, or both.
Reversion Guarantee
- The installations are handed over to the public authority in full working condition and ready for use.
- The concessionaire covers the costs of maintenance and final preparation prior to handover.
- The infrastructure continues in service under public ownership.
Decommissioning Guarantee
- The installations are removed, demolished or eliminated entirely.
- The concessionaire assumes the costs of demolition, waste removal and land restoration.
- The site is left clear and in a condition equivalent to its original state.

How Much Does a Surety Bond Cost?
The cost of a surety bond depends on several factors that determine the level of risk involved:
- The company’s financial strength
- The type of bond required (bid bond, performance bond, advance payment bond, etc.)
- The amount and duration of the bond
- The company’s track record
- The country where the bond will be issued
- The company’s technical and operational capacity
- Market conditions

Can a surety bond replace a bank guarantee?
Yes. Both surety bonds and bank guarantees are valid instruments for securing a contract, and either can be used.
The key difference lies in the financial impact on your business:
- Bank guarantee: uses part of your banking capacity and ties up liquidity or assets as collateral.
- Surety bond: does not affect your banking capacity and does not tie up capital.
Discover all the advantages of surety bonds compared with traditional bank guarantees.
How long does it take to issue a surety bond?
It depends on whether you already have a Plafond (pre-approved bonding facility) in place with the insurer or not:
- With a Plafond line: issuance is same-day, as the company has already been assessed and approved.
- Without a Plafond line: the required documentation must be submitted (financial statements, legal documentation, tender documents, etc.). Once received, you will normally receive a quotation within 48 hours.
Do you also arrange guarantees between private companies?
Yes. Surety bonds can be used both in contracts required by public authorities and in agreements between private companies.
- With public authorities: they are required by law to accept a surety bond as a valid form of guarantee, unless the tender documents state otherwise.
- Between private companies: both parties must agree on the type of guarantee accepted. Both a surety bond and a bank guarantee are acceptable where there is mutual agreement.
What types of guarantees do you arrange?
We arrange all types of surety bonds. The most common are:
- Bid Bond: to participate in public tenders and procurement processes.
- Performance Bond: to guarantee performance of the contract once awarded.
- Advance Payment Bond: when a company receives an advance payment and must guarantee its repayment if contractual obligations are not met.
- Maintenance Bond: provides cover during a defined period after completion, ensuring that the works have been carried out correctly and covering potential defects in materials, workmanship or design that may arise at a later stage.
- Retention Bond: replaces amounts retained by the contracting authority until completion of the contract. It avoids the retention of funds from certified interim payments due to potential defects.
