Most people in Portugal renew their insurance every year without thinking about it. The renewal notice arrives, they pay, and another year starts. This is exactly what most insurers are counting on. Renewal inertia means the insurer does not have to compete for your business each cycle — you are retained by default.
Portuguese law gives you a clear right to exit this cycle. Under Decreto-Lei 72/2008 on insurance contracts, and reinforced by the Lei 63/2022 reforms, policyholders have specific cancellation rights that insurers must honour. The process is not complicated once you understand the timeline. This guide walks through it for auto, home, and health policies.
The renewal date is the key date
For most Portuguese insurance contracts, the policy term is annual and renews automatically on the anniversary date. The cancellation window that matters is the period before that renewal date. The general rule under Portuguese law is that you can cancel without penalty by giving written notice at least 30 days before the renewal date. Some contracts specify 60 days — check your policy schedule (the condições particulares) for the specific notice period that applies to yours.
This means you need to plan backwards. If your auto policy renews on 1 June, and your contract requires 30 days notice, you must send the cancellation notice by 2 May at the latest. If you send it on 15 May, the insurer is legally entitled to apply one more annual premium and renew the policy for another year. Do not miss the window.
One important exception: if your insurer raises the premium at renewal, you have an additional right to cancel within 30 days of receiving the renewal notice, regardless of when the renewal date falls. Keep the renewal notice — if you exercise this right, the date on that document matters.
Step 1: Find your current renewal date and cancellation deadline
Your renewal date is in your condições particulares — the schedule of particulars that came with your original policy documents. If you cannot find the original documents, log into your insurer's customer portal or call their customer service line and ask for the renewal date and the required notice period in writing.
For mandatory third-party liability insurance on vehicles (seguro de responsabilidade civil automóvel), there is an additional consideration: your vehicle cannot be legally uninsured for a single day. Portuguese law (Decreto-Lei 291/2007) requires continuous coverage. Any gap between cancelling one policy and activating another makes you liable to a fine from the Instituto da Mobilidade e dos Transportes (IMT) and potentially creates legal exposure if an accident occurs during the gap.
Step 2: Get your new quote before you cancel
This is the step most people get backwards. They cancel first, then shop. The correct order is to have your new policy confirmed and ready to activate before you send the cancellation notice to your current insurer. Specifically, you want the new policy's start date set to the day after your current policy ends.
At Indie, you can get a binding quote in under three minutes, and you choose the policy start date at the time of purchase. If your current auto policy runs until 31 May, you simply set your Indie start date to 1 June. The moment you confirm payment, your new policy is active from that date and your documents are in your email. There is no delay between payment and coverage activation.
Step 3: Send the cancellation notice to your current insurer
The cancellation notice needs to be in writing. A phone call is not sufficient — insurers are entitled to require written notice and most do. The most reliable method is:
- Email to the insurer's official contact address (the one listed in your policy documents), with a clear subject line such as "Cancelamento de Apólice — [your policy number]".
- Follow up with a registered letter (carta registada com aviso de recepção) to the insurer's registered headquarters address. This creates a legal record of delivery date in case of dispute.
The cancellation notice must include: your full name, your NIF, the policy number, the coverage type (auto, home, health), and the requested cancellation date. Keep a copy of everything you send.
If you are cancelling because the insurer raised the premium, state this explicitly in your notice and reference the renewal notice they sent you. This activates the 30-day-from-notice cancellation right under Article 116 of Decreto-Lei 72/2008 and removes any ambiguity about your legal basis for cancelling outside the standard window.
Step 4: Pro-rata refund for unused premium
If you paid your premium annually and cancel before the year ends, you are entitled to a refund of the unused portion — calculated on a pro-rata basis. For example, if you paid for a full year and cancel eight months in, you are owed approximately four months of premium back.
The refund timeline is not strictly defined by law — most insurers process it within 30 days of the cancellation being confirmed. If you do not receive it within that period, follow up in writing. If the insurer refuses, you can file a complaint with the ASF's consumer complaints service, which takes insurer non-compliance seriously. The ASF complaint form is available on the ASF website (asf.com.pt) under the supervision section.
The special case of home insurance linked to a mortgage
If your home insurance was arranged through your mortgage bank — a common situation in Portugal, where banks often bundle home insurance with mortgage products — the process is slightly more complicated. Many mortgage agreements require you to maintain home insurance as a loan condition and give the bank a right of assignment (cessão de crédito) on the policy.
You can still switch, but you need to notify your bank at the same time as your insurer. The new policy must name the bank as a beneficiary on the buildings section (content/recheio is separate). Ask your bank's mortgage team for the exact endorsement wording they require. This is a standard request and they must comply with it. Critically: switching home insurer does not change your mortgage contract. The bank cannot penalise you for switching to a cheaper insurer, provided the new policy meets the minimum coverage requirements specified in your mortgage deed.
Health insurance: the waiting period trap
When switching health insurance, watch for waiting periods (períodos de carência). Most Portuguese private health policies impose waiting periods — typically 3 months for outpatient consultations and diagnostics, up to 12 months for maternity cover, and sometimes longer for certain specialist treatments. If you cancel your current health policy and then sign up with a new insurer, those waiting periods apply from day one of the new policy.
This means switching health insurance right before you expect to need it is a bad idea. The ideal time to switch is when you are healthy and unlikely to need coverage in the next three to six months. If you are in the middle of a treatment or expecting to give birth within the year, stay with your current insurer until you are past those events, then switch.
Some insurers offer waiting period waivers for customers switching from another insurer — ask specifically about this. It is not a legal right, but it is commercially offered by several Portuguese health insurers and is worth asking about when comparing plans.
After the switch: confirm your proof of coverage
Once your new policy is active, confirm two things. First, that you have a policy document with a valid policy number that can be verified against the ASF database. For auto insurance, the Agente Único document that confirms liability coverage registration is what traffic authorities check — make sure it reflects your new insurer and policy number. Second, check that the cancelled policy is confirmed as closed, not merely lapsed. An insurer may attempt to collect unpaid premiums on a policy they consider still active if the cancellation was not properly processed. A written confirmation from your previous insurer that the policy is cancelled and the account is settled closes this risk.
Switching insurance in Portugal is administratively straightforward once you know the timeline. The 30-day-before-renewal rule, a confirmed new policy in hand before you cancel, written notice with a registered letter backup — follow those three rules and you will not encounter problems.
