What parametric rain insurance actually is

Parametric is one of those words that sounds more complicated than it is. If you have seen it attached to cover for a festival or an event and wondered what it actually means, here is the plain English version: how it differs from the insurance you already know, and the two things people often mistake it for.

Ordinary insurance pays when you prove a loss

Most insurance you have bought works the same way. Something goes wrong, you tell the insurer, and you prove it. A receipt, a report, photos of the damage, a form describing what happened. Someone on the other end reviews your case and decides whether it qualifies and how much to pay. That review is the claims process, and it exists because the insurer needs evidence that your specific loss actually happened before it pays out.

It is a reasonable system, but it is slow by design, and it puts the burden of proof on you at the exact moment you are least in the mood for paperwork.

Parametric insurance pays when a number is crossed

Parametric insurance removes the proof step entirely. Instead of insuring against a loss you have to demonstrate, it insures against a number: an agreed trigger, set when you buy the policy, and a figure produced independently of you. If the figure crosses the trigger, the policy pays. If it does not, it does not. There is nothing to submit and nobody assessing your individual case, because the payout was never about your case. It was always about the number.

How this works with Rainy Refunds

With Rainy Refunds cover, the number is forecast rainfall. You buy a policy for the day of your event, with a rainfall trigger agreed for that venue and a set window of the day. At an agreed check time, we take the Met Office forecast for the venue and compare the rainfall forecast for that window with your trigger. If the forecast meets or passes it, you are paid automatically. There is no claim to make, no form to fill in and nobody out with a rain gauge afterwards: the forecast at the check time decides, and the payout follows it.

Rainy Refunds policies are underwritten by Tokio Marine HCC. Rainy Refunds Limited is an Appointed Representative of Stubben Edge and Partners Limited, which is authorised and regulated by the Financial Conduct Authority.

What it is not

It is not a ticket refund. A ticket refund, where one exists, comes from the event organiser and usually only if the event itself is cancelled. Rainy Refunds is separate cover you buy for yourself, and it pays out on the weather at the venue, not on a decision the organiser makes. The two can sit alongside each other; they answer different questions.

It is not a bet on getting wet. A bet is a judgement call: did you personally have a miserable, soggy day? Parametric insurance is not that, and it is not trying to referee your afternoon. It is a regulated insurance contract, settled against the Met Office forecast for a fixed location and window, not against how the day felt. It can feel very wet where you are standing while the forecast for the window stayed under the trigger, and no payout is due; or the forecast can pass the trigger and pay while you stay dry under a gazebo. The forecast decides, consistently, whichever way it goes.

Why the difference is worth knowing

The claims-free part is the headline, but the real point is what it removes: the argument. With ordinary insurance, the moment you need the payout most is also the moment you have to build a case for it. With parametric cover, that moment does not exist. The trigger, the window and the check time were fixed before the event started, so there is nothing left to negotiate once the forecast is in.

That is also why it is worth reading the trigger for your own venue rather than assuming it matches a friend's policy elsewhere. Rainfall triggers are set per location, because rain itself varies enormously from one place to the next, even a few miles apart.
