If you are changing health insurance company in Spain, one of the most important things to avoid is a gap in cover — when your current policy ends before your new policy starts. A gap can leave you without private healthcare access and may create problems if your insurance is being used for a visa, residency renewal, EU registration or family application. The safe approach is simple: line up your new Sanitas start date so it follows immediately after your current policy ends.
What it is
A gap in cover means there is a period when your old health insurance policy has ended but your new policy has not yet started. During this period you may not have private health insurance cover — and if your insurance is being used for official purposes, the gap may also create documentation problems.
Why it matters
A gap in cover can matter because:
Safest way
The safest way is to arrange the new Sanitas policy before your old policy ends, with the new start date lined up correctly. In some cases, a small overlap may be even safer than a same-day handover.
| Old Policy Ends | New Policy Starts | Result |
|---|---|---|
| 30 June | 1 July | No gap |
| 30 June | 5 July | Gap in cover |
| 30 June | 30 June | Overlap |
| 30 June | 25 June | Overlap and no gap |
Same day or next?
This depends on how the current policy end date is written. If your old policy covers you until the end of 30 June, the new policy should normally start on 1 July. If there is any uncertainty, it may be safer to create a small overlap rather than risk a gap. The important point is that there should be no uncovered period between the two policies.
Don't cancel early
You should not cancel your current policy until the new Sanitas policy has been reviewed, accepted and the start date confirmed. This matters because:
Renewal & deadlines
To avoid a gap, you need to know:
Many policies in Spain renew automatically, and cancellation is often required before renewal. See change health insurance before renewal in Spain and missed health insurance cancellation deadline in Spain.
Overlap
Yes — sometimes a small overlap is safer than a gap. An overlap means both policies are active for a short period. This may cost slightly more for a few days or weeks, but it can help avoid a break in cover while the new policy is confirmed.
Visa & residency
If your private health insurance is being used for a Spanish visa or residency renewal, avoiding gaps is especially important. This may apply to:
Your policy should normally show clear dates and continuous cover where private insurance is required. See change visa health insurance in Spain.
NLV
For NLV holders, the replacement policy should normally remain suitable for the Non-Lucrative Visa and should start immediately after the current policy ends — for example, if the current NLV policy ends on 30 June, the new Sanitas policy starts on 1 July. Avoid letting the current policy expire before the new one is active. See change NLV health insurance company.
DNV
For DNV holders, first check whether private insurance is still your main healthcare proof. If it is, avoid any gap between policies. If Spanish social security or public healthcare is now the main route, private insurance may be supplementary, but a gap still affects your private healthcare access.

EU residency
If private health insurance is being used for EU residency or green certificate purposes, avoid gaps before or around the appointment. If you now have public healthcare, employment, self-employment or S1 cover, private insurance may be supplementary, but you should still check before cancelling. See change EU residency health insurance.
Families
Families need extra care because every person's dates should be checked. A family gap can happen if:

Pre-existing
If you have pre-existing conditions, avoiding a gap is even more important. Sanitas may need to review medical history before confirming acceptance. If you cancel the current policy too early and the new policy is delayed, excluded or declined, you may lose cover.
Already ended
If your current policy has already ended, you may already have a gap in cover. You should act quickly, but carefully — do not hide the gap. Instead:
If the gap relates to visa or residency renewal, get advice quickly — see missed health insurance cancellation deadline in Spain.
Backdating
In general, you should not assume that a new health insurance policy can be backdated to cover a period before it was accepted and issued. The safest approach is to arrange the Sanitas policy before the current cover ends.
Step by step
Eleven steps to switch cleanly with continuous cover — apply first, cancel last:
Know exactly when your existing cover ends.
Many Spanish policies renew unless cancelled.
Often at least one month before renewal.
Give yourself time to plan dates properly.
Cover for you, your family or your visa route.
Be accurate on the application.
Do not cancel old cover yet.
Line it up so there is no uncovered period.
Covering the full required period.
On time and in the right way.
So you can show continuous cover if asked.
Risk by situation
A quick guide to the situations where a gap carries the most risk:
| Situation | Why a Gap Matters |
|---|---|
| Visa renewal | May affect healthcare proof |
| NLV renewal | Continuous private cover may matter |
| DNV renewal | Depends on healthcare route |
| EU residency | Private proof may need continuity |
| Family policy | One member may be left uncovered |
| Pre-existing conditions | New acceptance may not be automatic |
Timeline
Work backwards from your current policy expiry or renewal date:
| Timing | Action |
|---|---|
| 3 months before expiry | Start checking options |
| 2 months before expiry | Review medical and visa needs |
| 6 weeks before expiry | Apply for Sanitas |
| Before cancelling | Wait for acceptance |
| Before old policy ends | Confirm the start date |
| After new policy active | Cancel old cover correctly if appropriate |
