Comparison sites are paid by the insurers they list. Captive agents represent one carrier. Neither of those is independent, however the homepage words it.
Here is our structure, plainly. International cover is placed through SIP Medical Family Office — independent consultants in health management and international medical insurance, established in Switzerland since 1997, whose group companies are licensed as medical insurance intermediaries for the EU/EEA and the United Kingdom. We hold no insurance licences of our own, and that arrangement covers Switzerland, European Union, United Kingdom.
Working under a principal's licences is ordinary in this industry and rarely admitted. We say it in the first paragraph because the alternative — letting you assume we hold our own paper — is the kind of small omission this page exists to argue against. We hold no exclusive arrangement with any insurer, and no insurer owns any part of this business.
Here's the mechanism, because "independent" is easy to write and hard to check. International cover is placed on a courtage basis: the insurer pays a brokerage fee when a policy is placed. It is a percentage of the premium, which means we have no reason to sell you more cover than you need and no reason to steer you towards the most expensive plan. What we do have a reason to do is place you well — because we review your cover with you every year, for as long as you're our client, and a policy that turns out to be wrong is our problem too.
Check it rather than take our word for it. The entries are SIP's, not ours — we hold no licence of our own to look up: FINMA intermediary register — Switzerland · FMA register — Liechtenstein, SIP Europe AG licence 10116 · FCA register — United Kingdom. The full arrangement is set out on our about page.
