Pretty much every bookmaker provides offers for football accumulators and punters come to expect a bonus. Tennis accumulators are still very popular though, but only a selection of bookmakers have offers for them. Generally, tennis accumulator offers fall into one of two categories:

  • Bonus on winnings – If your accumulator wins, and you have a certain amount of selections, bookmakers will pay you a bonus on top of your winnings.
  • Insurance – If you miss out on winning by just one selection, bookmakers will refund your losing bet as a free stake.

Bookmakers tend to be split down the middle with bonuses and insurance offers when it comes to football, but with tennis, the bookmakers do tend to favour bonuses. It’s quite rare now to find insurance offers (10Bet used to have it, but reverted to bonus).

So when betting your tennis accumulator, you’ll want to pick the bookmaker that will not only award you a bonus if you win but awards you the biggest bonus based on the number of selections you have. There are three bookmakers currently offering a bonus on tennis accumulators. They are:


bet365’s fantastic Tennis accumulator offer includes matches from all the top tournaments and events. You can earn a bonus of up to 70% of your winnings if you place accumulators on To Win Match, First Set Winner and Set Betting markets for Singles and Doubles matches from any Grand Slam, ATP, WTA or Challenger Tour event, as well as Singles and Doubles matches from the Davis Cup, Fed Cup and Hopman Cup. Place a pre-match accumulator with bet365 of 2 or more selections combining matches from any of these competitions and, if successful, the relevant bonus will be added to your winnings.

The bonus will not apply where a stake has been fully Cashed Out. Where a stake has been partially Cashed Out, the bonus will be calculated based on the remaining active stake. Where all selections within the bet have been marked as won and this has been Cashed Out for the full return value, the bonus will apply and the maximum bonus that you can receive is £100,000 or currency equivalent. If a qualifying bet is edited using our Edit Bet feature, the bonus will be calculated based on the new stake. Where a bet has been edited to include or amend a selection for an event that is In-Play, the bonus will no longer apply.

Bets placed with Bet Credits, Parlay Cards, Teasers or combination bets with bonuses such as Lucky 15’s or Lucky 31’s do not apply for this offer.

T&Cs apply. Only available to new and eligible customers.

  • 10Bet Tennis Accumulator Bonus – Up to 50%

10Bet also offer a bonus on tennis accas.  At the beginning of 2019, they tweaked the bonus structure, reducing the top bonus from 60% to 50%, and increased the minimum odds per selection, but it is still strong. There is a minimum of three selections for the bonus to kick in.

Each selection within the accumulator must have minimum odds of 1.50. There isn’t much in it, but versus bet365, you do get a marginally bigger bonus up until 15 selections upwards with bet365.

There is a maximum bonus of £10,000 that 10Bet will award with this offer. Here is the full scaling tier of the bonus:

  • Boylesports Tennis Accumulator Insurance- Up to £20

Boylesports do not offer a bonus on accumulators but do have an insurance offer which is available for all sports, including tennis.

If need to have 5+ selections in your accumulator, and if one leg lets you down, then Boylesports will refund your losing stake up to £20. There is only one other insurance offer available for tennis, and that’s from Winner. Although this is great for Boylesports customers, if you have a Winner account you might want to take advantage of the higher refund (£25) and the potential to earn a bonus in conjunction.

To wrap up

In our opinion, bet365 is the best place to be placing your tennis accumulators. They have a fantastic bonus that grows with the more selections you have.

Alternatively, if you’re going very long on your accumulator with 15+ selections, in which case MansionBet will give you the biggest bonus. At that point though, if the odds are long enough, you might find that the cap on your bonus becomes the maximum winnings which are ‘only’ £10,000 with MansionBet.
