UK iGaming Market: The Operator’s Guide to Acquiring Players

The UK iGaming market made £8.3 billion in gross gambling yield (GGY) from April 2025 to March 2026, across online casino, betting, and bingo.

The market is big, but growth is getting harder to buy. New account registrations fell 3 percent over the same period, and Remote Gaming Duty, the tax on online casino profits, nearly doubled to 40 percent in April 2026.

Market reports on the UK online gambling market stop at revenue and regulation, so they never tell you what a player costs or where to find one when the largest brands own paid search.

Below, you’ll see the market’s size by sector, the UKGC rules and 2026 tax rise, and what UK search clicks cost. It closes with what a first-time depositor costs from Blockchain-Ads data and a five-step plan for buying UK players on the open web.

How Big Is the UK iGaming Market?

The UK gambling market size was £17.5 billion in GGY from April 2025 to March 2026, up 4.4 percent, according to the Gambling Commission’s annual industry statistics. Without lotteries, it was £13.2 billion, up 4.7 percent.

Remote casino, betting, and bingo made £8.3 billion, up 6.9 percent, and accounted for about 63 percent of the non-lottery market. Online is now the main arena for acquisition, and it’s where the money is still growing.

Online casinos led with £5.7 billion, up 14.8 percent, and online slots made up 84 percent of it. Online betting fell 6.6 percent to £2.4 billion, and online bingo fell 13.8 percent to £147.8 million.

Land-based gambling is losing ground. Its GGY rose just 1.1 percent to £4.9 billion, and the number of betting shops fell 3.6 percent to 5,617.

The online player pool has stopped growing. Operators recorded 32.4 million new account registrations, down 3 percent, and 25.7 million active accounts at the end of March 2026.

These count accounts, so one person with three accounts counts three times. Still, the direction is clear: operators are earning more from a shrinking pool of sign-ups, which makes each new depositor worth more and harder to win.

A few large groups own the UK’s best-known brands: Flutter (Sky Bet, Paddy Power, Betfair), Entain (Ladbrokes, Coral), Evoke (William Hill, 888), and bet365. New operators compete with their budgets and brand recognition for the same players, so they need channels where those groups aren’t already dominant.

Editorial Note: All Gambling Commission statistics cover Great Britain only, because Northern Ireland has its own gambling law.

Online Casino vs. Sports Betting

Online casinos now make more than twice the GGY of online betting, and the gap keeps widening as casino grows and betting shrinks.

Football is the biggest betting sport, with £1.2 billion in online GGY, followed by horse racing at £769.3 million. Betting GGY also swings with results, because a good run for punters cuts what operators keep.

Casino offers reach the larger revenue pool, but casinos now carry the higher tax. Sportsbooks can lead with football around big fixtures, then introduce casinos later through separate offers, since a single bonus can no longer span both products.

How the UKGC Regulates Online Gambling

Every operator serving British players needs a Gambling Commission license, and its rules cover the product, the player checks, and the ads. A breach can cost an operator its license, so each rule below shapes how you acquire players.

The pattern across the table is fewer levers per player. Offers are capped, stakes are capped, and high spenders face checks, so acquisition has to win on product, targeting, and tracking.

The 2026 Tax Rise

The UK’s gambling tax increase leaves operators with less revenue from every player they acquire.

On April 1, 2026, Remote Gaming Duty rose from 21 percent to 40 percent. 

According to HMRC's policy paper, Remote Betting Duty will also increase from 15 percent to 25 percent in April 2027, although online bets on UK horse racing will remain taxed at 15 percent. Bingo Duty was abolished in April 2026, offering some relief to bingo operators.

The pressure extends beyond online gambling. The October 2026 Budget raised Machine Games Duty from 20 percent to 25 percent on machines with stakes over £1, from April 2027.

For online casinos, every £100 in gross gambling yield (GGY) now leaves £60 after duty, down from £79. That £19 reduction tightens acquisition margins and can extend payback periods. 

This means that casino operators must reassess what they can afford to spend acquiring players, while sportsbooks face similar pressure from April 2027.

Why Paid Search Is Crowded in the UK

Paid search is crowded in the UK because brands bidding on high-intent gambling terms pay up to $32 per click, according to Semrush data pulled in November 2026. 

At that price, new operators run through a test budget fast.

Semrush saw only one or two ads per term, so few brands bid, but each pays a premium. Licensed operators can still advertise once Google certifies them, yet at $19 to $32 per click, a $10,000 test buys only 300 to 500 clicks.

Organic is no easier because Semrush rates “online casino” and “casino sites” at 91 and 96 out of 100 for keyword difficulty. Affiliates, the other main route, take a cut of every player they send.

The open web reaches the same adults by audience instead of keyword, outside the most expensive search auctions.

What It Costs to Acquire a Player in the UK

A first-time depositor (FTD) costs about $78 across Blockchain-Ads iGaming campaigns worldwide. That’s a global benchmark, so UK costs can run higher or lower.

Working example. Here’s how a $10,000 test budget would perform at the global benchmarks:

1. At $0.50 to $1.00 a click, $10,000 buys 10,000 to 20,000 clicks.
2. At about $78 per FTD, the same $10,000 brings in roughly 128 first deposits.
3. That means roughly 0.6 to 1.3 percent of clicks turn into a first deposit.

If your cost per first deposit runs well above that benchmark, fix conversion before adding budget. More spend on a leaky funnel only buys more of the same leaks.

How to Acquire Players in the UK

To acquire UK players, track first deposits server-to-server, buy reach on the open web where the big brands aren’t bidding, and then add retargeting. 

Here’s how to build that acquisition system, step by step.

Reach Players Outside Search

Reach players outside search with programmatic display, native, video, in-app, and connected TV (CTV) placements. On search, you compete with established gambling brands at $19 to $32 a click.

Instead of relying on search keywords, you can target eligible adult audiences using relevant contextual and permitted audience signals.

For example, sportsbooks can advertise alongside suitable sports coverage, while casino brands can use video and CTV to showcase their gaming experience.

The priority is reaching relevant adults without exposing under-18s to gambling ads. Use age controls and targeting methods that comply with UK gambling advertising rules.

Build Creative That Passes UK Rules

Lead with what players can expect from your product, such as game selection, live dealer tables, app features, or withdrawal speed.

Every claim must be accurate, information-rich, and consistent with the player’s actual experience.

If you’re promoting bonuses, keep wagering within the Gambling Commission’s 10x limit and make significant offer conditions clear. Add an 18+ notice and responsible-gambling messaging to every ad.

Avoid claims that suggest guaranteed wins or risk-free gambling. Your creatives must also comply with CAP and BCAP requirements, including restrictions on content that strongly appeals to under-18s.

Track Registrations and First Deposits Server-to-Server

Set up server-to-server (S2S) tracking to send registration and first-deposit events from your backend to your advertising platform. Clicks tell you who visited, while first deposits tell you which campaigns acquired depositing players.

Capture the click ID when someone lands on your website, associate it with their account where permitted, and include it in the conversion postback alongside the relevant event and deposit value.

This reduces reliance on browser cookies and improves conversion tracking, although cross-device attribution still requires reliable identity matching and appropriate consent.

Let Campaigns Learn, Then Add Retargeting

Give new campaigns their first weeks to learn which audiences, placements, and creatives attract depositing players before you judge them.

Avoid judging performance on clicks alone. Instead, focus on first-time depositors (FTDs) and cost per FTD to understand acquisition efficiency.

Once you’ve built a sufficiently large, eligible audience, introduce retargeting to reconnect with people who showed interest but didn’t complete registration or deposit. 

Segment your retargeting audiences by behavior, exclude existing depositors where appropriate, and apply responsible gambling safeguards.

Measure the Players Your Ads Added

Run an incrementality test to measure how many new players your ads actually bring in. Not every attributed deposit is an incremental acquisition, because some players would have registered or deposited without seeing your ads.

To measure the difference, keep a comparable holdout group that doesn’t receive the campaign. Compare conversion outcomes between exposed and control groups to estimate how many additional first deposits your advertising generated.

This helps you distinguish campaigns that create new demand from those that simply capture existing demand.

Acquiring UK Players With Blockchain-Ads

Blockchain-Ads suits UK-licensed casino and sportsbook operators, and the agencies and affiliates that serve them, buying paid traffic at volume outside search. 

Here’s how Blockchain-Ads helps:

• Reach beyond search: display, native, video, in-app, and CTV, with the UK as one GEO through geo and device targeting.
• Optimize for depositors: campaigns target registrations and first-time deposits, measured by CPA, deposit value, and ROAS.
• Protect payback: server-to-server conversions carry deposit value, so you see which campaigns cover the 40 percent duty.
• Stay compliant: only licensed operators and affiliates are admitted, and landing pages need an age notice, responsible-gambling information, and clear promo terms.

Self-service starts at a $10,000 deposit, and managed service starts at $30,000 monthly spend, with license documents available on request.

Where the UK iGaming Market Is Heading

A leading UK iGaming market prediction from H2 Gambling Capital projects UK online GGY, including offshore play, rising from £8.8 billion in 2025 to £9.6 billion in 2031. That projection, from a June 2026 report for the Betting and Gaming Council, is about 1.4 percent a year, a real-terms decline.

The same report expects licensed operators’ share to fall from about 92 percent to 85 percent, partly because of the tax rise. Higher duty, falling registrations, and closing betting shops all point to a flat market.

In a flat market, growth comes from taking share. Buy players where the biggest brands aren’t bidding, and prove each one through to first deposit.
