Gubbing explained: what the regulator's own data shows about restricted betting accounts
Gubbing is the informal term for a bookmaker cutting off a customer it no longer wants. The account usually stays open. What changes is the maximum stake, which can fall to a few pence, or the range of markets still available to bet into.
Operators have never published their restriction figures. In July 2025 the Gambling Commission asked the largest online firms in Britain to hand theirs over.
How many accounts get gubbed?
The request covered every commercial restriction applied during 2024, across 14,923,840 active accounts. The Commission counted an account as active if it placed at least one bet between 1 January and 31 December 2024.
Of those, 643,779 carried a restriction of some kind: 4.31 per cent, or one account in 23.
Two things pull that number in opposite directions. Operators differ widely in how often they restrict, driven by risk appetite, size and customer mix, so a 4.31 per cent average says little about any individual firm. And because one person routinely holds accounts with five or six bookmakers, 643,779 restricted accounts represents a good deal fewer than 643,779 restricted people.
What a restriction actually looks like
Operators reported four broad methods. An account can carry more than one, which is why the shares below total more than 100 per cent.
| Type of restriction | Share of restricted accounts | Share of all active accounts |
|---|---|---|
| Stake factor reduction | 62.17% | 2.68% |
| Account closed for commercial reasons | 51.69% | 2.23% |
| Betting facilities withdrawn (stake factor 0.00) | 19.15% | 0.83% |
| Market-specific restriction | 5.72% | 0.25% |
Stake factoring is the common one, and it covers an enormous range. A customer cut to 99 per cent of the standard maximum counts as stake factored. So does a customer cut to 1 per cent. The Commission broke the severity down:
| Stake factor band (% of unrestricted maximum) | Share of stake-factored accounts |
|---|---|
| 90% to under 100% | 6.04% |
| 50% to 89% | 7.50% |
| 10% to 49% | 29.43% |
| 1% to 9% | 36.22% |
| Above 0% to 1% | 22.41% |
Close to three in five stake-factored accounts sit below 10 per cent of a normal maximum. The Commission notes the bands total just over 100 per cent because some operators counted an account twice where it moved band mid-year or carried different factors on different markets.
The distance between those bands matters more than the headline rate. A customer factored to 0.99 has been mildly inconvenienced, while a customer factored to 0.01 has a £100 bet turned into a £1 bet, which finishes the account as a working proposition even though it stays open and still counts as active in the survey.
Are gubbed customers actually winning?
The Commission asked operators to split accounts by lifetime profit and loss on settled bets, then compare restricted accounts against everyone else.
Among all active accounts, 25.42 per cent are in profit and 72.54 per cent are in loss. Among restricted accounts, 46.78 per cent are in profit and 51.29 per cent are in loss. A restricted customer is therefore around 1.8 times more likely to be sitting on a lifetime profit than an average one.
Most write-ups of this data stop there, which loses the more interesting half. More than half of restricted accounts are losing money. Profitability is one input among several, and operators also model bet timing, market selection, staking patterns and closing line value. A customer who repeatedly takes a price shorter than the closing line looks dangerous long before the P&L shows anything. Plenty of people get gubbed while down.
Why bookmakers are allowed to do it
The Commission does not stop this and has said the job is not its to do. Operators may manage their own liabilities, a position set out in the 2023 Gambling White Paper, which also confirms there is no universal service obligation in gambling.
Chief executive Andrew Rhodes addressed the discrimination question head on:
"Being a successful bettor is not a protected characteristic in discrimination law."
The Commission did flag two second-order effects it wants to understand better. Restrictions may push customers towards unlicensed operators, and they encourage multi-accounting, which weakens the controls that detect crime and integrity threats. It is also pressing operators to tell customers up front how and when an account might be restricted, before anyone deposits.
None of that gives a restricted customer anything to appeal to. A licensed British bookmaker can decline your business on commercial grounds, and the regulator has said it will not intervene.
Do exchanges gub?
An exchange matches you against another customer rather than taking the other side itself, so a winning customer costs it nothing at settlement. Neither of the two largest UK exchanges restricts stakes for profitability. Both charge winners more instead.
Betfair applies an Expert Fee on top of standard commission, which replaced the Premium Charge on 6 January 2025. An account qualifies only when all three of these hold:
- Gross profit and loss over the last 52 active weeks exceeds £25,000
- Lifetime gross profit and loss is above £0
- The account has bet into more than 100 markets
The fee is capped at 40 per cent, below the 50 and 60 per cent rates the Premium Charge could reach, and it runs on a rolling 52-week window rather than lifetime profit, so a losing run can return an account to 0 per cent. Betfair also applies a buffer that offsets recent losses and commission generated against what is owed.
Smarkets runs the same idea through commission tiers. The Standard Tier is 2 per cent on net profit per market. Customers clearing £25,000 in net profit over the previous 12 calendar months move to a 3 per cent Select Tier, with seven days' email notice.
The rate change matters less than the change in what gets charged. Standard Tier customers pay only on markets they win. Select Tier customers pay 3 per cent on each individual settled bet, on the profit when it wins and on the losses when it loses, applied to all trading activity on the account once the tier switches. Any commission promotion is permanently forfeited. Smarkets puts the share of its customer base hitting any tier limit at 0.2 per cent.
Both firms have landed on £25,000 as the point where a winning customer starts costing more.
So the choice across the two models comes down to a ceiling on stake size against a larger share of profit.
Where Pred sits
Pred runs a peer-to-peer sports prediction exchange. Every position is matched against another user taking the opposite side, and settlement happens in USDC on Base. Pred operates the venue and earns a fee on volume, holding no position against any trader.
With no exposure to manage, there is no commercial reason to restrict anyone, and a high-volume profitable trader is worth more to the venue than a low-volume unprofitable one. Makers pay nothing. Takers pay a fee on the trade whether the position settles up or down, and that fee does not move with how well the account performs.
Trading carries risk. Positions can settle at a total loss, and nothing above is a forecast of returns.
Frequently asked questions
What does gubbed mean?
Gubbed means a bookmaker has restricted or closed your account for commercial reasons rather than any breach of terms. In most cases the account survives while the maximum stake is cut, which Gambling Commission data shows falls below 10 per cent of the normal limit for close to three in five restricted accounts.
Is gubbing legal in the UK?
Yes. The Gambling Commission has confirmed that mandating how operators manage commercial liabilities sits outside its regulatory remit, and the 2023 Gambling White Paper states there is no universal service obligation in gambling. Operators may decline business on commercial grounds provided they do not discriminate on protected characteristics.
How do I know if I have been gubbed?
Stakes get rejected above a low threshold, promotional offers stop appearing, or specific markets disappear from the account. The Gambling Commission is currently pressing operators to improve how and when they tell customers that a restriction has been applied.
Can I avoid getting gubbed?
Nothing reliably prevents it if an operator has decided you are unprofitable to serve. Multi-accounting to work around a restriction breaches operator terms and can forfeit balances, and the Commission has named it as a practice that undermines wider regulatory controls.
Which betting sites do not limit winners?
Exchanges do not restrict stakes for profitability, because customers are matched against each other. Betfair and Smarkets both charge more above £25,000 in profit, through the Expert Fee and the Select Tier. Prediction exchanges including Pred charge on volume rather than performance.
