Record the IT delivery level before it leads to disputes
A ROZ lease (the standard Dutch model lease) covers a lot, but rarely says anything concrete about digital infrastructure. The IT-Label gives you an objective, verifiable description to refer to.

Where it goes wrong today
Brochures promise "fibre available", but the contract records nothing. At handover, during an outage or at the end of the lease, it is unclear who supplies, manages and pays for what.
The IT-Label describes what a building delivers digitally, determined by an independent Certified Partner. That gives you a factual basis for clear agreements. Also read IT in the ROZ lease: who is responsible?.
How to include the IT-Label in a ROZ lease
Seven practical points to discuss with your client:
- Description of the leased property. Mention the IT-Label and the certificate number, or attach the certificate.
- IT Demarcation List as an annex. Record for each component who supplies, manages, maintains and replaces it, and who owns it.
- Handover. Record the IT delivery level in the handover report, so there is a reference point at the end of the lease.
- Tenant facilities. Agree whether IT facilities installed by the tenant may stay or must be removed, and whether compensation applies.
- Access and provider. Arrange access to technical rooms and the free choice of internet provider.
- Service charges. Does the landlord supply the network or wifi? Then record how this is settled in the service charges.
- Recertification. An IT-Label is valid for two years. Agree when it will be recertified, for example after a renovation.
Not legal advice
The IT-Label provides the facts about the digital infrastructure. You make the legal translation into the contract. The certificate can also serve as an annex in a purchase or sale.
