Who should consider which

If you primarily want the lower basic premium and affordable dental coverage, CZ saves you approximately EUR 24 per year on the basic package and offers dental add-ons from around EUR 8 per month compared to EUR 10 at Zilveren Kruis. Over a year, choosing CZ with dental coverage could save you roughly EUR 48 compared to the same setup at Zilveren Kruis.

If you prioritise having the widest possible choice of contracted healthcare providers, especially specialists and hospitals, Zilveren Kruis has the largest network in the Netherlands. This can be particularly relevant if you live outside the Randstad or have specific medical needs that require specialist care.
