Maximum Rent Increase 2026: What Your Landlord Can Ask, and How to Object
The maximum rent increase in 2026 is 4.1% for social housing (from 1 July), 6.1% for mid-rent (middenhuur) and 4.4% for free-sector rentals (both from 1 January). These are hard ceilings set by the Dutch government — a landlord who asks for more is not automatically entitled to it, and you can push back. This guide lays out the exact percentages, who they apply to, what notice your landlord owes you, and the steps to object through the Huurcommissie.
What are the 2026 rent increase caps?
Three ceilings apply, depending on your contract type and rent level. Social housing (rent below the liberalisation threshold, roughly the WWS 143-point line) is capped at 4.1% from 1 July 2026, down from 5% the year before. Mid-rent (middenhuur) contracts under the Wet betaalbare huur are capped at 6.1% from 1 January 2026. Free-sector (vrije sector) contracts, typically above roughly €900-1,000 and outside the regulated bands, are capped at 4.4%, also from 1 January 2026.
The social cap is calculated as the average inflation over the past three years plus 0.5 percentage points — inflation from December 2022 to December 2025 averaged 3.6%, giving 4.1%. For mid-rent and free-sector contracts, the government takes the lower of CAO wage growth or inflation over the past year and adds 1 percentage point. Wage growth was 5.1% and inflation 3.4%, so the lower figure (3.4%) plus 1 point gives the free-sector 4.4%. Mid-rent uses CAO wage development directly plus an extra point, landing at 6.1% (source: NOS, Rijksoverheid).
Does my rent fall under social, mid-rent or free-sector rules?
Your rent level at the start of the contract, not your income, decides which cap applies. Social housing covers rents below the liberalisation threshold set by the WWS points system — broadly contracts worth up to roughly 143 points. Mid-rent covers the 144-186 point band introduced by the Wet betaalbare huur. Free-sector covers anything above that, generally unregulated rents above roughly €900-1,000 a month. If you're unsure which band you're in, check your rent against the WWS points calculation — see our guide to lowering your rent via WWS points and the Huurcommissie and the Wet betaalbare huur explainer.
What notice must my landlord give?
For regulated (social and mid-rent) contracts, your landlord must notify you in writing at least two months before the increase takes effect, stating the new rent, the percentage, and the date it starts. For free-sector contracts, the notice period and exact mechanics usually follow what's written in your rental contract, since free-sector increases are governed by contract clauses within the statutory cap rather than a single fixed government procedure. In all cases, the increase can never exceed the applicable 2026 ceiling, regardless of what the contract says.
Can my landlord ask for more than the cap?
Only in specific circumstances. Social landlords can add an income-dependent surcharge of up to roughly €50 or €100 a month on top of the base 4.1% increase for middle- or higher-income households, depending on household size and income thresholds — this is a separate mechanism, not a higher percentage cap. A landlord can also propose a rent increase tied to home improvements (e.g. after renovation), which follows its own rules and requires your consent or a Huurcommissie ruling. Outside these cases, a demand above the sector cap is not valid and you don't have to pay it.
How do I object to a rent increase?
For social and mid-rent contracts, send your objection directly to your landlord before the increase date using the Huurcommissie's model objection letter (bezwaarschrift), available at huurcommissie.nl. If the landlord doesn't withdraw or adjust the increase, you can escalate by submitting a request (verzoekschrift) to the Huurcommissie — for the 1 July 2026 round, the deadline for this escalation is 31 October 2026. The Huurcommissie checks whether the proposed increase matches your contract type, the correct percentage, and proper notice, and issues a binding ruling. There's a small fee, refunded if you win. For free-sector contracts, there's no Huurcommissie route for the annual increase itself — but if you believe your free-sector rent was ever miscategorised and should actually fall under the regulated WWS system, you can still request a points check (see our WWS/Huurcommissie guide).
What does this mean for your rental search?
If you're renting, not just sitting in a tenancy, these caps matter when you compare asking rents to what a similar home cost last year — a jump far above 4.4-6.1% on a re-listed property is a signal to check the WWS points rather than assume it's simply 'the market'. If you're negotiating a renewal, knowing the exact cap for your contract type means you can push back with a number, not just a feeling. For background on how the broader 2026 rent-control framework works, see our Wet betaalbare huur guide, and if you're still searching for a home, faster alerts won't change the legal cap, but they do help you compare asking rents across more listings before you commit.
