Dutch telecom contracts explained: notice period, switching service and bundle discounts
Door Lisa van den BergBijgewerkt op 7 min lezen
The Dutch terms you meet when ordering internet, TV or mobile, explained in English: opzegtermijn (notice period, at most one month after the initial term), overstapservice (the new provider cancels for you), nummerbehoud (number porting), bedenktijd (cooling-off), yearly price indexation and bundle discounts from KPN, Odido and VodafoneZiggo.
Short answer
As of 29 September 2026: Dutch telecom contracts have an initial term (minimale looptijd) of at most 2 years. After that they continue indefinitely and you can cancel with a notice period (opzegtermijn) of at most one month (ACM ConsuWijzer). When you switch home internet, the switching service (overstapservice) lets the new provider cancel your old contract, with at most one working day without service; number porting (nummerbehoud) must be done within one working day (ACM ConsuWijzer, ACM ConsuWijzer). Most providers raise prices once a year in line with inflation, which you cannot refuse if your contract allows it. Bundle discounts for combining internet and mobile go up to €20 a month at VodafoneZiggo (VodafoneZiggo).

How does switching provider work in the Netherlands?
For home internet, you mainly deal with the new provider. When you order, choose the switching service (overstapservice) and give your current provider and customer number. The new provider cancels your old contract and coordinates the switch date. During a switch, internet, TV and phone may not be down for more than one working day (ACM ConsuWijzer). If the new provider has not cancelled your old contract, cancel it yourself as soon as possible.
For mobile, you order with the new provider and ask to keep your number. Porting must happen within one working day, and you can still port your number up to one month after your old contract has ended (ACM ConsuWijzer). Porting ends the old contract, but you still owe any remaining months of an initial term. More: how the switching service works (in Dutch).
Can your provider raise the price during your contract?
Yes, if your contract says so; most Dutch providers include a yearly inflation adjustment. If the rise stays within what your terms allow, you cannot cancel for free because of it. If a provider raises the price beyond what the contract allows, or without it having been agreed, you can usually cancel for free. And once you are past the initial term, you can always leave with at most one month's notice. More: price rises and free cancellation (in Dutch).
How do bundle discounts work?
You get a monthly discount for combining home internet and mobile, usually at the same address. The amounts differ by provider:
| Provider | Name | Discount (as reported) |
|---|---|---|
| VodafoneZiggo | One (since June 2026) | Up to €20 a month combined on new Ziggo internet plus Vodafone mobile |
| KPN | Combivoordeel | Level 1: up to €7.50 a month plus double data and extras |
| Odido | Klantvoordeel | Up to €7.50 on mobile plus €5 on internet (Unlimited plans) |
Sources: VodafoneZiggo (8 June 2026), Providers.nl (May 2026). Discounts depend on your plan and speed and can change; check the provider's current terms.
A bundle ties you in
If you cancel one part, the discount on the other part usually disappears. Factor that in if you might move or leave the Netherlands before the contract ends.
What should you check before you sign?
