What Is Acca Insurance in Betting?

Last updated: 26/08/2026

Four legs in. One to go. And then some team you've never watched in your life concedes in the 88th minute.

Every acca punter knows that specific afternoon.

Acca insurance is the promotion built for it: one leg lets you down, and the bookmaker gives you your stake back, usually as a free bet.

Two things before we go further, though. It isn't insurance in any regulated sense, whatever the name suggests. And Midnite doesn't offer it, which we'll come back to properly rather than burying halfway down.

What is acca insurance?

Acca insurance is a bookmaker promotion that refunds the stake on an accumulator when exactly one selection loses, typically as a free bet up to a set amount. The bet itself still loses. Qualifying rules on leg count, minimum odds and refund caps apply, and they vary by bookmaker.

How does acca insurance work?

Here's a generic example, since terms differ everywhere it runs.

You put £10 on a five-leg accumulator with a bookmaker offering insurance on five legs or more.

Four legs win. The fifth loses.

Without the promotion, that's a tenner gone.

With it, you get your £10 back. Almost always as a £10 free bet rather than cash.

Note what hasn't happened there. The acca has still lost. There's no payout from the four winners, because an acca needs every leg to come in. What you've got is a free bet token with an expiry on it, not money in your account.

That's the promotion in full. Useful in exactly one scenario, invisible in every other.

What does "one leg loses" actually mean?

This is where refunds get won and lost, and where most explainers go quiet.

Exactly one. Not one or more.

Two losing legs and there's no refund anywhere the promotion runs. The cover is for the near miss, nothing else.

Void legs are not losing legs.

A postponed match or a voided selection settles at 1.00, drops out of the acca, and the bet recalculates on what's left. A void typically doesn't trigger the refund, and it can quietly disqualify the bet by dropping the leg count below the minimum.

Six legs with a five-leg minimum? Survives one void. Five legs? Doesn't.

Cashing out usually kills it.

Use cash out, even partially, and the bet generally stops qualifying.

If you take one thing from this page, take the void one. It's the mechanism that catches people, because a void feels completely harmless right up until it changes what your acca is.

Acca insurance rules: what terms usually apply?

Bookmakers running acca insurance typically attach some or all of these:

• A minimum number of legs, commonly four or five.
• Minimum odds per leg, so nobody qualifies by padding an acca with 1/50 shots.
• The refund as a free bet rather than cash, in most versions.
• A refund cap, a maximum returned regardless of stake.
• An expiry on the free bet, often just a few days.
• Qualifying markets and sports, frequently limited to specific football markets.

You'll also see it written as "5 acca insurance", or 4, or 6. What does 5 acca insurance mean? Only that the offer applies to accas of five legs or more, so a five-fold qualifies and a four-fold doesn't.

Every one of those varies by bookmaker and by version of the offer, and operators change or pull these promotions regularly. The terms attached to a specific offer on the day are the only ones that count.

How free bets themselves work, stake-not-returned included, is covered in our free bets guide.

Does Midnite offer acca insurance?

No. Midnite doesn't offer acca insurance.

Rather tell you here than let you find out at the checkout.

Here's what we do run on multiples instead.

What Midnite offers on accas instead

Accas are a big part of Midnite. They just arrive without the insurance wrapper.

The acca hub is home for multiples across Midnite's football betting and everything else on site.

Midnite also publishes pre-built boosted accas: ready-made multiples at pre-set enhanced prices that you back directly rather than assembling yourself. Our odds boost explainer has the full mechanics. [Pending publish: /blog/what-is-odds-boost]

Whatever's running sits on On This Week, with the ongoing rewards line-up in Bet Club and our own promotions on the Midnite free bets page.

Acca insurance vs acca boosts vs early payout

Three different promotions, one word in front of all of them, and they get muddled constantly. These are the concepts as they exist across the market, not a Midnite menu.

Acca insurance refunds your stake, usually as a free bet, when exactly one leg loses. It pays you back for a near miss.

An acca boost improves the price or the winnings on an accumulator. It changes what a winning acca pays and does absolutely nothing when it loses.

Early payout settles a selection as a winner before full time once a condition is met. The famous one is two-up on football, where a team going two goals clear pays out even if they get pegged back. What is 2UP in betting covers that properly.

Insurance softens a loss. A boost sweetens a win. Early payout moves the finish line.

What acca insurance doesn't do

The name oversells it, so let's be clear-eyed.

It covers one losing leg. That's the lot.

It doesn't make an acca safe, and it doesn't stop an acca losing, because a refunded acca is still a lost bet.

The refund is usually a free bet with its own terms and expiry, not cash you can withdraw.

And it does nothing at all about the underlying arithmetic. Every leg you add still has to win, so the price gets longer because the bet gets less likely, refund or no refund.

A promotion can soften one particular bad Saturday. It can't change what an acca is.

FAQs

Why is it called an acca?

Acca is short for accumulator, the bet type where several selections combine into one bet and the odds multiply together.

Every selection has to win for the acca to win.

Is an acca the same as a bet builder?

No.

An acca combines selections from different matches. A bet builder combines selections from the same match. The odds multiply the same way, but they're different bet types with different rules.

What happens to acca insurance if a leg is void?

A void leg settles at 1.00 and drops out rather than counting as a loss, so it typically doesn't trigger a refund.

It can also drop your leg count below the offer's minimum, which usually disqualifies the bet from the promotion entirely.

Is the acca insurance refund cash or a free bet?

Usually a free bet up to a cap, with its own expiry and terms, rather than withdrawable cash. Some versions differ, so the specific offer's terms decide it.

Where that leaves you

Acca insurance hands back your stake, usually as a capped free bet, when exactly one leg of a qualifying acca lets you down. Void legs, cash out and leg minimums all decide whether it applies.

Midnite doesn't run it.

What Midnite does run is the acca hub, pre-built boosted accas, and whatever's live on On This Week.

However you build your multiples, size them to money you'd genuinely not miss, and set your deposit limits before the weekend starts rather than during it. Support and tools live in Responsible Play.
