Rent indexation, automatic and legally correct
No more guessing what you're allowed to raise this year. Protiva works with the current Dutch consumer price index and the statutory cap per segment. It prepares the rent increase for you, including the notice letter and deadlines.
From index figure to applied increase
Fetch the CPI
Protiva retrieves the current consumer price index from Statistics Netherlands. That index is the basis for the permitted increase.
Check the statutory cap
Each segment has its own ceiling. Protiva determines the maximum (the rent ceiling) and takes the lower of the CPI and that cap.
Apply & give notice
One click: the new rent is recorded and the rent-increase letter, with the correct deadlines, is ready to go.
Residential and commercial: each with its own rule
Residential tenancy
Self-contained homes in the regulated and mid-market segments have a statutory maximum percentage each year. Protiva calculates with the lower of CPI and that ceiling, so the proposed increase stays within the maximum.
Commercial tenancy
For business premises and free-sector homes the increase usually follows the indexation clause in the lease, often tied to the CPI. Protiva uses the right index and period.
Indicative and based on the rules in force at the time (reference date 2026). This is not legal advice; check any special provisions in your lease.

Frequently asked questions
Am I allowed to raise the rent this year?
In most cases yes, but it depends on your lease and the segment. Self-contained homes in the regulated and mid-market segments have a statutory maximum percentage each year; for the free sector and commercial property the increase usually follows the indexation clause in the lease (often the CPI). Protiva works out which rule applies per lease and shows you the maximum you may charge.
How much can the rent go up?
Protiva uses the current consumer price index from Statistics Netherlands and tests it against the statutory maximum for your property's segment. The lower of the two is your permitted increase. You see the exact amount and percentage before you commit to anything.
Does Protiva also send the notice to the tenant?
Yes. When you apply the indexation, Protiva generates the rent-increase letter with the correct effective date and notice period, ready to share through the tenant portal or as a document. You meet the notice requirement without doing the maths yourself.
