Best Odds Guaranteed on Combination Forecasts: UK Concessions

BOG Limitations on Exotic and Combination Slips
Best Odds Guaranteed is the most familiar UK bookmaker concession after each-way. Every shop window carries it as a banner. Every app promotes it in the racing section. And yet I’d estimate four in five regular punters can’t tell you whether it applies to a forecast bet. The answer, when you dig into it, is mostly no – and the corners where the answer is yes are worth knowing because they can mean the difference between collecting an SP-derived dividend and collecting whatever price your early-morning ticket locked in.
BOG sits at the centre of the regulatory debate too. With remote betting GGY at £2.6 billion in the financial year to March 2025 and horse racing accounting for £766.7 million of that figure, every concession that affects forecast pricing has industry-scale consequences. The product mechanics are simpler than the politics – but the politics is where BOG’s future on exotic markets is being negotiated.
Where BOG sits in the wider UK bookmaker concession landscape
BOG on win and each-way bets is a standard offering – back a horse at 5/1 in the morning, the horse drifts to 8/1 SP, your bet settles at 8/1 because the SP exceeded your taken price. Lose if the SP shortens, win if it lengthens. The concession costs the bookmaker money on every drifter, but in aggregate it keeps customers in the system who’d otherwise hedge their bets across multiple operators.
The reason BOG doesn’t naturally extend to the CSF is structural. The CSF dividend is itself an SP-derived figure – there’s no «early price» to lock in for comparison. You can’t back a forecast at 50/1 in the morning and check what the SP would have been because the morning price isn’t a CSF price, it’s just an indicative number from the bookmaker. Most operators simply don’t run an early-price market on the CSF at all. The dividend is the dividend, calculated after the off from the actual SPs.
Some bookmakers – typically the larger high-street operators – do offer their own fixed forecast prices ahead of the off, distinct from the CSF. On those products, BOG sometimes applies in a limited form: if you back forecast at the early fixed price and the post-race CSF is higher, your bet settles at the CSF. The concession is narrow and varies by operator, but it exists in pockets.
The operators who extend BOG to forecast products
The honest landscape is fragmented. A handful of major operators run an early-price forecast market for the biggest UK fixtures – Cheltenham, Royal Ascot, Grand National, Glorious Goodwood – and apply BOG to those markets in some form. The product mechanics are operator-specific: at one operator the early price is matched against the SP-derived CSF post-race, at another it’s matched against a derived bookmaker-internal forecast price, at another the BOG simply doesn’t carry beyond win and each-way at all.
Outside the marquee Festival days, early-price forecast markets are rare. On a routine Tuesday card at Wolverhampton or Lingfield, no operator offers a fixed forecast ahead of the off. The CSF on those races is the only forecast product available, and there’s no pricing benchmark against which to apply BOG.
The practical test for any reader who wants to use BOG on a forecast slip is straightforward: check the slip terms before submitting. If an early forecast price is shown and the operator confirms BOG applies, the concession is live. If only the CSF is offered, the concession isn’t applicable. Don’t assume the win-market BOG banner extends to your forecast – it rarely does.
A worked example – forecast with BOG versus straight CSF
Take an early-morning forecast price of £30 on a £1 stake (offered by an operator running early forecast markets on a Cheltenham Festival contested handicap). The race goes off, the result is the forecast you backed, and the post-race CSF returns at £42 per £1.
Without BOG, your settlement is the £30 you took. The bookmaker holds the £12 difference between the early price and the SP-derived dividend. With BOG applied to the forecast market, your settlement becomes the £42 CSF figure – you collect the higher of the two prices automatically.
Now reverse the example. Same early price of £30. The race result you backed still wins, but the CSF returns at £24 because a withdrawal shortened the post-deduction SPs of the placed pair. Without BOG, you collect your £30. With BOG, you still collect your £30 – the concession works as a one-way ratchet, paying the higher price but never the lower. The concession is asymmetric in your favour.
Across a sustained sample of early-priced forecast bets with BOG, the long-run effect is positive expected value because the SP-derived dividend more often drifts in the punter’s favour than against. The Tote+ Exacta beats the CSF in 77% of cases – which gives a useful indicator that comparable margins should be available between an early-priced fixed forecast and the post-race CSF on the same pair.
Getting your early forecast on early enough to matter
The window for early-priced forecast markets is narrow. Most operators who offer them open the market the evening before the race or the morning of, and the prices update as the morning progresses. By 30 minutes before the off, the early forecast market typically closes or transitions to a near-SP price that’s no longer materially different from the eventual CSF dividend.
The discipline that actually captures BOG value on forecasts is taking the price early enough that the SP can drift away from it. A forecast taken 10 minutes before the off, when the market has already largely settled, captures very little BOG value because the SP is unlikely to drift significantly from the price you locked. A forecast taken at 9am, when the market is still loose and the morning betting hasn’t yet shaped the SPs, captures the most BOG value if the result you backed comes in.
The trade-off is that early forecast markets also carry the risk of bigger movements against you on non-BOG situations. If the operator’s early price is more generous than the eventual CSF, taking it locks in your value – but only because the bookmaker’s risk-pricing models think the eventual CSF will be lower. The early price is the bookmaker’s edge against you, BOG is the concession that softens that edge for the punter who hits the result.
For the broader question of when fixed-odds beats pool, the comparison of reverse and combination forecasts covers the mechanical structure that BOG sits on top of.
Does BOG apply to a £1 combination forecast at every UK bookmaker?
No. BOG on forecasts is operator-specific and applies mostly on marquee Festival days where bookmakers run early-priced forecast markets. On routine Tuesday and Wednesday cards, most operators offer only the CSF without an early price, so there’s no benchmark against which BOG can apply.
If BOG doesn’t apply, why bet a fixed forecast rather than wait for SP?
Because some early forecast prices are genuinely more generous than the eventual CSF – particularly on contested handicaps where the bookmaker’s risk model under-prices certain outsider pairs. Taking the early price captures that value even without BOG, but the punter accepts the downside risk that the CSF could come back higher than the early-priced ticket.
