Blackjack is a popular card game where the aim is to try and beat the dealer by getting closer to 21 points, without going over.
Alongside the main hand, you may sometimes see extra betting options such as insurance. For many, this may be confusing the first time it appears on the screen or at the table.
This guide explains what the insurance side bet is, how it works, and why players often weigh it up carefully before deciding. By the end, you will better understand when it can be offered, how any payouts are handled, and why the choice is not as straightforward as it first seems.
Insurance is a separate side bet that becomes available in most classic versions of blackjack when the dealer’s face-up card is an Ace. It does not replace your main bet, but sits alongside it.
Here is how it works in simple terms:
Not all blackjack games offer this option. Online casinos, including those licensed in the UK, may offer different versions of blackjack where insurance is either included or excluded to speed up gameplay. Checking the table rules before you start should confirm whether the option is available.
Insurance is only offered at a specific moment. When the dealer shows an Ace, you may choose to place the extra bet before the hidden card is revealed. The stake is set at half your main wager.
For example, if your main bet is £2, the insurance option would cost £1. The dealer then checks the facedown card:
The important detail is that this bet does not change how your main hand is played. It is separate and resolved once the dealer checks their hidden card.
Insurance only appears when the dealer’s upcard is an Ace. The option is given before any player actions such as hitting, standing, doubling, or splitting. In a casino, the dealer will ask if you want insurance; in online versions, you will usually see a prompt appear on screen.
If the dealer’s upcard is not an Ace, insurance is not offered. Because blackjack rules can vary depending on the game provider, it can be worth checking the table’s information panel to see if the insurance side bet is part of the rules.
The potential payout for insurance is fixed at 2 to 1. In a multi-deck game, which is standard online in the UK, the chance of the dealer actually having blackjack when showing an Ace is less than the possible return the bet provides. This means the insurance option is, in the long run, favourable to the house rather than the player.
Taking insurance does not increase the value of your hand, or give you any advantage in how you play it. It simply covers the specific situation where the dealer has blackjack. For this reason, many players prefer to decline it and continue with their main hand only.
Most players avoid insurance because of the imbalance between the potential payout and the true odds of the dealer holding blackjack. Over repeated hands, the side bet tends to return less than it costs.
Another reason is simplicity. By skipping side bets, you can focus on the decisions that directly affect your hand, such as whether to hit or stand. This can help make the game easier to follow, especially if you are new to it.
Insurance and even money are connected, but they apply in different situations.
Insurance is available to all players when the dealer’s face-up card is an Ace. Even money only comes into play if you already have blackjack and the dealer’s upcard is also an Ace.
Choosing even money means your blackjack is paid straight away at 1 to 1. This avoids the chance of a push if the dealer also has blackjack, but it also means giving up the higher 3 to 2 payout you would normally receive.
In simple terms, even money is the casino’s way of offering insurance to players holding blackjack, presented as a guaranteed 1 to 1 return instead of waiting to see how the dealer’s hand finishes.
Insurance is treated separately from the main game, so it carries its own house edge.
In many multi-deck blackjack versions, the main game has a relatively low house edge (often around 0.5% when using optimal basic strategy). The insurance bet, by contrast, is much higher, around 7–8% in most multi-deck games.
Rule variations can alter these figures:
Because rules are not the same across all casinos or game providers, it may be a good idea to check the information panel or game rules before playing.
