Plus 10 is an industry-funded bonus scheme for British and Irish Flat thoroughbred owners and breeders. Qualified two and three-year-old horses can win a £10,000 (€12,500) bonus on top of race prize money.

The bonus is shared between a horse’s registered owner, the payers of the scheme’s first two registration stages – typically the breeder and in some cases pinhooker – and trainer, jockey and stable staff.

Each year, more than £7.5 million in bonus prize money will be made available across more than 750 races in Britain and Ireland.



  • 2YO: All Class 2, 3 and 4 Maiden, Novice and Conditions and Class 5 Fillies Only Maiden and Novice races*.
  • 3YO: All Class 2, 3 and 4 Maiden and Conditions, Class 5 Fillies Only Maiden races* and Class 5 maiden and conditions races over a race distance of 11f and further.

*Subject to the total prize fund being less than £100,000


  • 2YO: 100 bonuses available on all two-year-old, non-black-type races rolled over until all 100 bonuses are won.
  • 3YO: Unclaimed two-year-old bonuses applied to three-year-old winners of Maiden races from the beginning of the next year, until all are won.


Plus 10 is funded by a combination of registration fees from owners and breeders, in addition to funding from the Horserace Betting Levy Board, British Horseracing Authority, Horse Racing Ireland, Goffs, Goffs UK and Tattersalls.

Bonus Payments:

Where all three registrations stages have been paid, the full £10,000 (€12,500) will be paid out to winning connections. Horses which are part entered into Plus 10 can win a share of bonus prize money, regardless of whether a horse has been fully qualified for the scheme.

The bonus payments will be as follows: £1,000 (€1,250) paid to foal registrant where only the Foal Registration has been paid and £2,000 (€2,500), split equally between foal registrant and yearling registrant, where only the Foal and Yearling Registrations have been paid. Horses are able to win one bonus only.


What is the Plus 10 definition of a British/Irish domiciled stallion?

For the purposes of Plus 10, a British or Irish domiciled stallion is a stallion that is recorded in the General Stud Book as standing in Britain (England, Scotland and Wales) or Ireland (Southern and Northern) at the time of covering.

What is the Plus 10 definition of a British/Irish domiciled mare?

For the purposes of Plus 10, a British or Irish domiciled mare is a mare based permanently at a British/Irish stud or thoroughbred breeding premises which is registered as such and for which foaling returns are made to the General Stud Book. All produce from such mares are eligible for Plus 10 provided that the mare remains based in Britain or Ireland (other than for periods of temporary travel abroad for covering lasting no longer than a continuous period of nine months) in the calendar year prior to the horse’s year of birth.

Registration & bonuses

There are three registration stages which must be paid in order for a horse to be qualified to win a £10,000 (€12,500) Plus 10 bonus.

  • Foal Registration
  • Yearling Registration
  • Owner Registration

The £10,000 bonus is split:

  • 75% to the registered owner at the time of the horse’s win
  • 10% to the payer of the Foal Registration
  • 10% to the payer of the Yearling Registration
  • 5% to the trainer, jockey and stable staff connected to the winning horse

Each registration stage must be paid by its stipulated deadline in order for a horse to remain eligible:

  • Foal Registration – due by 31 August in the foal year, cost £150/€187.50
  • Yearling Registration – due by 30 June in the yearling year, cost £200/€250
  • Owner Registration – due by 28 February in the two-year-old year, cost £350/€437.50
    (discount of £50/€62.50 if paid while the horse is a yearling)
  • Breeze-Up Purchases:
    Two week allowance for new owners to pay Owner Registration from date of purchase

Note: The rate of exchange is set at £1:€1.25. Advance registration payments are permitted. Payment may be made in sterling or euros. Details of payment options are included in the registration forms.

Breeders and pinhookers of Plus 10 registered horses entered can win a share of bonus prize money, regardless of whether a horse has been fully qualified for the scheme.

If a registration stage is not paid by its stipulated deadline, a horse becomes ineligible for Plus 10 and retrospective payments from subsequent owners are not permitted. There will be no refund on earlier registration payments if a horse becomes ineligible.
