Your renewal went up: what is actually driving it
The short answer
A renewal increase is rarely one thing. It is usually your age band, general medical inflation and the end of a first-year discount arriving in the same letter, on top of how the insurer's whole book of business has performed. None of that makes an increase automatically fair or automatically unreasonable — but knowing which components are moving tells you whether the problem is fixable where you are. Two dates matter more than the number: when the insurer had to tell you, and by when you have to reply.
Take the increase apart
An increase reads as a single decision aimed at you personally. It is nothing of the sort, and separating out the components is the whole of the useful work here, because one of them is permanent, one recurs every year, and one will not happen again.
Your age band. Spanish health premiums are priced by age, in bands rather than year by year. Within a band, ageing does very little. Crossing into the next one moves you to a different price entirely, which is why an increase can be modest for four years and then abrupt in the fifth. This is structural, it applies to every insured person on the policy independently, and it is not negotiable — it reflects the fact that a portfolio of older insured people costs more to treat. It also means the same increase can be entirely explicable at 49 and again at 60, and puzzling in between. Where age banding dominates the picture, cover over 60 is the guide that deals with it properly.
Medical inflation. The cost of the care the policy buys rises independently of you: consultant fees, hospital rates, imaging, new techniques and new drugs. Health cost inflation generally runs ahead of general consumer inflation, because medicine keeps adding capability rather than only getting cheaper at what it already does. This component appears on every policy in the book, whatever the holder’s age or claims.
Portfolio claims experience. This is the one most often misunderstood. Individual health policies are priced at the level of the whole book, or of large segments of it — not by scoring your personal claims the way a motor insurer scores your accidents. If the segment you sit in cost more to run than expected, that feeds into next year’s price for everyone in it. So “but I barely used it” is a true statement that does not, by itself, describe an error. Insurance pools risk; pooling is the product.
The end of promotional pricing. A first-year discount, a joining offer or a temporary rate coming off is not a price rise at all — it is the advertised price arriving. It is worth identifying separately, because it is the component most likely to make an increase look dramatic and the one least likely to repeat next year.
The renewal notice: what it should tell you, and when
The timing is set by law, and it is the part that works in your favour. An insurer must notify any modification of the contract at least two months before the current period ends, and a change in premium is a modification. A new price landing three weeks before your policy year runs out is therefore not the normal order of things, and it is worth saying so in writing.
Your own documents should also tell you where you stand without a phone call: the conditions and periods for opposing renewal are required to be highlighted in the policy itself.
A renewal communication should let you answer four questions without ringing anybody: what the new premium is, what the new policy year runs from and to, what else has changed in the contract, and how and by when you may oppose the renewal.
That third question is the one people skip. Price is not the only thing that moves at renewal. Excesses and copayment amounts can change, annual limits and sublimits can be reset or reduced, the medical network can gain and lose providers, and the wording of exclusions can be updated. An increase of a few euros a month alongside a materially reduced limit is a worse outcome than a larger increase with the cover intact — and only one of those two changes is printed in large type.
The deadline the letter starts
Whatever you decide, decide inside a window. Notice that you are not renewing has to reach the insurer before the current insurance period ends, and the statutory minimum for a policyholder is a month. Your own conditions may allow longer, never less, so read the opposition clause rather than assuming the minimum applies to you. Miss the window and, in the ordinary case, the policy renews and you are committed for another year.
That is the single reason a renewal letter should not go into a pile with the rest of the post. Cancelling health insurance covers the notice, the form it has to take and how to make it provable; the switching guide works the same date backwards into a full timetable if leaving is on your mind.
A renewal that crosses an age band
A policyholder had seen small, unremarkable adjustments for four consecutive years and had stopped reading the letters closely. The fifth increase was several times the size of the previous ones, and her first assumption was that she was being penalised for a course of physiotherapy claimed that spring.
She asked the insurer to itemise it. Most of the increase was an age band she had crossed on her last birthday; a smaller part was the general annual adjustment; the physiotherapy featured nowhere, because her product was not individually experience-rated. That changed what she did next. She stopped looking for an argument about the claim, which was not the cause and which she would not have won. And she recognised that a competitor’s quote — priced against the same age, on the same logic — would not simply undo the step, so the honest comparison was between two age-banded prices rather than between “a rise” and “no rise”. She restructured the copayment on the policy she already held, kept her accumulated position, and diarised the next band boundary.
What you can do other than leave
Leaving is one option among several, and it is the one with the most side effects — new underwriting, possible new exclusions, possible restarted waiting periods, and the loss of the position described in continuous cover. Before treating it as the answer, exhaust the things that do not require any of that.
Restructure the policy you already hold. Moving between a copayment and a no-copayment variant of the same product, adjusting an excess, or dropping a module you never use can change the price meaningfully, and on many products it avoids fresh underwriting — confirm that for your own product rather than assuming it. Copayments versus no copayments sets out what that trade actually costs you in use.
Review who is on the policy. Family policies price each insured person, and an adult child who has moved out or a partner with cover through work may no longer need to be there. Family cover covers how these are structured.
Check the cover level against your actual use. Modules you never call on still cost money, and whether your plan is built around a network or around reimbursement of your own invoices is a structural choice with a real price attached.
Ask. Retention is a real function at Spanish insurers. Whether anything is available to you is product-specific, but a direct question about options on your existing policy costs one call and starts no clock running.
Then, and only then, compare. Comparing policies properly means comparing what you would actually be covered for after underwriting — not two headline prices, which is how people talk themselves into worse cover for less money.
When staying is the right answer
Sometimes the increase is real, the market is no better, and the correct move is to pay it. That is a legitimate outcome, not a failure of nerve, and it is most often right in three situations.
If you or anyone on the policy has developed a condition since joining, that condition is being handled as an ongoing claim where you are. Somewhere new, it is medical history, and it may be excluded or loaded. The value of what you would give up can exceed the entire increase.
If you are close to an age boundary, or already past several, competitors are pricing you on the same age logic. The comparison is between two age-banded prices, not between a rise and no rise.
And if the network you rely on — a particular hospital, a consultant you trust, a paediatrician your children are used to — is the reason you hold the policy, verify the alternative properly in the network directories before letting a price rise cost you it.
What makes staying a decision rather than inertia is having checked. Read the letter, itemise the increase, note the deadline, look at what else is available, then choose. An increase you have understood and accepted costs exactly the same as one you were startled into paying, and it leaves you in a better position next year.
When your renewal letter arrives
- Check the date on the letter against the date your policy year ends — the insurer owes you at least two months' notice of any change to the contract
- Identify what changed besides the price: excesses, limits, network, copayment amounts and exclusions can all move at renewal
- Ask the insurer to itemise the increase, in particular whether you have crossed an age band
- Check whether a first-year or promotional discount has ended, which is a different event from a price rise
- Find the opposition-to-renewal terms highlighted in your own policy, and count back from your renewal date
- Compare against what your policy covers for you now, not against a new customer's brochure price
Have your renewal reviewed
An increase is worth testing rather than absorbing. Send us the letter and your current policy details before you accept it or give notice, and we will set out what else is open to you and on what terms.
