Lucky 15 with a void horse: how it settles, and the bonus

A void horse (a non-runner) does not void a Lucky 15. Its single returns the stake and every multiple containing it drops one fold, the rule Sky Bet, William Hill and Paddy Power publish, so the slip settles as two Patents on the three runners plus one unit back. Whether the one-winner consolation survives is set by each bookmaker’s terms.

Updated 16 October 2026: Sharper title and summary; direct answer cites Sky Bet, William Hill and Paddy Power; operator cascade re-read; Sky Bet antepost exception corrected; FAQ updated.

This piece is evergreen: there is no news peg, and none is claimed. What is dated is the provenance. This desk read Sky Bet’s non-runners support entry on 11 September 2026 and, the same day, tried six other operators’ Lucky 15 or bonus rules pages; the table below records what came back.

What is a Lucky 15, and what does one non-runner touch?

Four selections, fifteen bets: four singles, six doubles, four trebles and a four-fold. Take one horse out and eight of the fifteen contain it. The seven bets on the other three horses are a Patent, and they are untouched.

Sky Bet’s page puts the rule for the other eight in one sentence: in most circumstances the bet is void and the stake returned, and where the selection is part of a multiple, “the bet will become the next accumulative bet down e.g. a treble becomes a double”. Applied to a Lucky 15, the seven reduced bets are a second Patent on the same three horses, so a £15 Lucky 15 with one non-runner is two £1 Patents on three runners plus a pound back.

Sky Bet’s page, re-read on 16 October 2026, carries one exception, and it is Sky Bet’s, not a convention: an Antepost bet on a non-runner “will be classed as a losing bet”, and “All Antepost bets for the Cheltenham Festival will be refunded if placed under the Non-Runner No Bet promotion.” bet365’s non-runners FAQ, read the same day, says antepost bets are all in, run or not, unless otherwise stated. That is the antepost trade set out in the Rule 4 audit — a slice of the winnings on the day, or the whole stake in advance — and a Lucky 15 struck antepost inherits it.

Lucky 15 non-runner: does the bonus still apply?

The all-winners bonus is arithmetic. With three runners you cannot have four winners, and no reading of anybody’s terms is needed to say so. The incumbent explainer on the subject, Non Runners Today Racing, says the same, and then says of the one-winner consolation that terms “vary between firms” — without naming a firm. That is the gap this desk set out to close and, from this desk, could not. AceOdds’ Lucky 15 calculator page, read on 16 October 2026, states as a general rule rather than any firm’s terms that bonuses and consolations need every selection on the slip to run and apply only to the win part of each-way bets. That is the condition to look for in your bookmaker’s terms; no operator page this desk read says it.

Here is what the operators’ servers returned to plain requests on 11 September 2026.

On 16 October 2026 this desk re-read the William Hill, Paddy Power and bet365 non-runner help pages through a search engine’s copy of each page, because direct requests to those three still returned 403; Sky Bet’s page loaded directly. William Hill’s help article works the Lucky 15 line by line: four singles become three singles and a void, six doubles become three doubles and three singles, four trebles become a treble and three doubles, and the four-fold a treble. Paddy Power’s help entry names the Lucky 15 and says the bet still stands, settled without the non-running selection. bet365’s non-runners FAQ gives the same treble-to-double rule without naming the Lucky 15.

So the scoped finding is narrow: none of the operator pages read on either date mentions a Lucky 15 bonus or consolation. That is not a claim that any firm withdraws the consolation after a void, and it is not a claim that any firm honours it. If your bookmaker’s terms say the consolation needs all four selections to run, the void leg costs you the bonus; if they say it applies to the restructured bet, it does not.

The settlement, worked in pounds

A £1 Lucky 15, £15 staked. Horse A wins at 5/1. Horses B and C lose. Horse D is a non-runner. The prices are hypothetical; the cascade is Sky Bet’s rule as read. No consolation yet.

Read that against the same slip with all four running and only A winning: one £6 single, fourteen losers, £6 back.

Now the consolation, as a hypothetical only. If an operator’s terms honoured double the odds on the one winner and applied it to the original £1 single, that line returns £11 instead of £6, and the slip £18. At treble the odds the single returns £16 and the slip £23. Those lines assume the consolation attaches to the surviving single and that the collapsed AD double is settled as a plain single with no uplift — an assumption no operator page was read to confirm.

One more line item. If a fancied horse is withdrawn from A’s race after you took 5/1, the surviving leg takes a Rule 4 deduction on top of everything above, and it compounds through every line that contains A. The scale is in the Rule 4 audit and is not repeated here.

Can you do a Lucky 15 each-way, and what does it cost?

An each-way Lucky 15 is thirty bets, fifteen win and fifteen place, so a £1 each-way Lucky 15 costs £30. The cascade applies to both halves in the same way, because each half is its own multiple. What the place half is worth depends on the place terms of each race, which is the subject of the each-way audit, and whether a consolation applies to the each-way version at all is, again, a line in the bookmaker’s terms and not something this desk has read.

Questions people ask about a Lucky 15 non-runner

What happens if a horse is void in a Lucky 15?

The bet stands. The single on the void horse is void and its stake returned, and every multiple containing that horse drops one fold: the four-fold becomes a treble, three trebles become doubles, three doubles become singles. The seven untouched bets stay as they were, so the slip becomes two Patents on the three runners plus one unit back. Sky Bet, William Hill and Paddy Power each publish this rule (read 16 October 2026).

Do you still get the Lucky 15 bonus if one horse doesn’t run?

The all-winners bonus cannot apply, because with three runners you cannot have four winners. Whether a one-winner consolation survives is set by each bookmaker’s own Lucky 15 terms. The operator pages this desk read on 16 October 2026, from Sky Bet, William Hill, Paddy Power and bet365, do not mention a Lucky 15 bonus; calculator sites such as AceOdds state, as a general rule, that every selection must run.

Do you get a bonus on a Lucky 15?

The Lucky 15 is usually sold with two add-ons on top of the fifteen bets. The first is a consolation if exactly one selection wins, commonly advertised as double or treble the odds on that winning single. The second is a percentage uplift on total returns if all four win. This desk read no operator’s figures for either on 11 September 2026, so the numbers are the bookmaker’s to state, not ours.

How much does a Lucky 15 cost?

Fifteen times the unit stake, because it is fifteen separate bets on four selections. A £1 Lucky 15 costs £15; a £2 Lucky 15 costs £30. Each-way doubles that again, to thirty bets, so a £1 each-way Lucky 15 costs £30. A non-runner does not refund the slip; it returns the single on the void horse and shrinks the eight multiples that contained it.

The file, both columns

Verdict

The practical reading is short. Price the Lucky 15 as fifteen plain bets and treat any consolation or all-winners uplift as a promotion — audited the way price boosts are, with the non-runner clause read before the stake goes on, not after the horse comes out.

Non-runners cluster, too. A week in which three of your Lucky 15s lose a leg will look like the product failing when it is the fixture list, and variance can swallow a real edge for months either way. Set a stake so that a run of restructured slips costs the ledger its arithmetic and nothing else, and never add a bet to win a void leg back.
