Betfair Sportsbook Review: What Its Prices Cost You Per £100 Staked
This is a price measurement, not a product review. Betfair Sportsbook was measured on the same basket as every other book in the August 2026 study — 40 of its match-result markets priced in the capture window — and came out 4th of 18 in the ranking — 6.86% margin, £6.42 per £100 staked. Nothing about its app, its offers or its service is measured here.
No commercial relationship. We earn nothing from Betfair Sportsbook and cannot link it. It is measured and published on identical terms to the operators we do earn from.

The margin is the overround: add up the implied probability of every outcome in a market and a fair book totals 100%. Betfair Sportsbook totalled 106.86% on average, and that surplus is the charge. Expressed against your stake rather than against the fair book it comes to £6.42 per £100 — the two figures measure the same thing from different ends, which is why both are printed rather than one.
In this window the keenest book measured £5.67 per £100 and the dearest £10.58. Betfair Sportsbook sat £0.75 above the keenest end and £4.16 below the dearest. Its immediate neighbours were Ladbrokes just keener and Unibet just dearer.
Betfair Sportsbook odds by competition
The same operator, the same window, 5 different answers — 1.30 points between Betfair Sportsbook’s own best and worst. A margin is not one number an operator sets; it is set market by market.
| Competition | Margin | Cost per £100 | Against its own average |
|---|---|---|---|
| ATP Canadian Open | 5.96% | £5.62 | -0.90 |
| Premier League | 6.99% | £6.53 | +0.13 |
| League Two | 6.99% | £6.53 | +0.13 |
| League One | 7.07% | £6.60 | +0.21 |
| Championship | 7.26% | £6.77 | +0.40 |
Betfair Sportsbook priced ATP Canadian Open most keenly at 5.96% and Championship least keenly at 7.26%, a span of 1.30 points between its own best and worst competition. A bettor who only ever backed ATP Canadian Open would therefore pay a different price at this operator than one who only ever backed Championship, without either of them doing anything differently.
One point of confusion worth heading off: the Betfair name appears twice in this study. The figure here is the sportsbook, where Betfair Sportsbook sets the prices and the margin is the charge. The exchange listed separately on the method page is a different product entirely — customers price it against each other and the operator takes commission on net winnings, so its implied figure is not a margin and the two are not comparable.
Read this one with more caution than the rest. Betfair Sportsbook priced 40 of the markets in the basket, the smallest sample of any book here, because it did not have a price up for every fixture at the moment of capture. The figure is calculated the same way; it simply rests on less.
What a 6.86% margin costs over a year
Betfair Sportsbook charges 6.86% on turnover, not on deposits. Stake the same pound twice and it is charged twice, which is what turns a small percentage into a yearly figure.
| Staked in a year | Cost at 6.86% | At the keenest measured | Difference |
|---|---|---|---|
| £1,000 | £64 | £57 | £7 |
| £5,000 | £321 | £284 | £37 |
| £20,000 | £1,284 | £1,134 | £150 |
These are arithmetic on the measured margin, not a prediction about anyone’s results. What happens to individual bets is a separate matter entirely; the margin is the part that is known in advance and charged whatever happens.
The third column is the same turnover at the keenest margin in this window, Betfred. At £5,000 staked the gap is £37 a year — worth setting against whatever the sign-up offer is worth, because one is charged every year and the other arrives once.

Betfair Sportsbook is a brand, not a licensee. The Commission licenses PPB Counterparty Services Limited under account 39439 for remote betting on real events, and every price measured on this page was published under that licence. The account has held it since November 2014.
The same licence covers Paddy Power in this study. Sharing a licensee is not the same as sharing a book: Betfair Sportsbook and Paddy Power finished 1.70 points apart and published the same prices in only 9 of the 40 markets both priced. One licence, more than one trading position.

We record these whether or not we earn from the operator, and we do not summarise them beyond what the Commission published. An action is against the licensed entity, not against the brand, which is why the entity name is printed above it.
Where Betfair Sportsbook sits in the study
4 of 18 puts Betfair Sportsbook in the keenest third of the table. That is one capture window, one market type and 5 competitions, so it is a finding about this sample rather than a verdict on the operator. A different basket would produce a different order, and saying so is not a hedge — it is what the method page commits us to.
The full table, exchanges included, is on the register; how the figure is calculated is on the method page.
There is no link to Betfair Sportsbook on this page. We hold no arrangement with it and it earns us nothing, which does not change how it was measured or where it appears in the ranking.
Questions about Betfair Sportsbook
What margin did Betfair Sportsbook charge?
6.86% across the 40 match-result markets we sampled on 7 August 2026, which works out at £6.42 per £100 staked. That is one capture window on one market type and is not a statement about its prices today.
Is Betfair Sportsbook cheap or expensive compared to other bookmakers?
It ranked 4 of 18 bookmakers in this sample, keenest first. The keenest measured £5.67 per £100 and the dearest £10.58, so Betfair Sportsbook sat £0.75 above the keenest end and £4.16 below the dearest.
Is Betfair Sportsbook licensed in Great Britain?
Yes. The Gambling Commission licenses PPB Counterparty Services Limited under account 39439, licence 039439-R-319330-012, held since November 2014 and active when we checked the public register. Betfair Sportsbook is a brand operated under that licence, not a licensee in its own right.
Who actually operates Betfair Sportsbook?
PPB Counterparty Services Limited, which also holds the licence covering Paddy Power in this study. Separate brands, one licence holder — and, as the figures here show, not necessarily the same prices.
Does Betfair Sportsbook have a regulatory record?
The public register currently lists one action against PPB Counterparty Services Limited, the most recent dated 17 December 2025. The register is not a complete history — older matters age off it. The detail is set out below with a link to the Commission.
Does the margin apply to every market at Betfair Sportsbook?
No. These are match-result markets across 5 competitions. Within that sample its keenest competition was ATP Canadian Open at 5.96% and its dearest was Championship at 7.26%, a span of 1.30 points. Other market types are not measured here at all.
What does a 6.86% margin cost over a year?
At £5,000 staked across a year, roughly £321. The margin is charged on turnover, not on deposits, so it recurs on every bet rather than once — which is why it can outweigh a welcome offer several times over.
Why is there no link to Betfair Sportsbook?
Because we hold no commercial arrangement with Betfair Sportsbook and earn nothing from it. It is measured, ranked and published on exactly the same terms as the operators we do link, which is the point of publishing the unlinked ones at all.
Can I check these figures myself?
Yes, and that is the intention. The formula, the basket, the exclusion rules and the test vectors are published on the method page, and the odds calculator runs the same arithmetic on any prices you enter. The figures here are ours and can be wrong; where a check shows they are, they change.
