How to Open an Online Casino?

To open an online casino for customers in England, Scotland or Wales, an operator will normally need to:

1. Establish a suitable company and disclose its ownership and funding.
2. Develop a detailed business and compliance plan.
3. Apply to the UK Gambling Commission for a remote casino operating licence.
4. Obtain Personal Management Licences or submit the required Annex A declarations.
5. create anti-money laundering, customer verification and safer-gambling controls.
6. Build or acquire a compliant casino platform and licensed games.
7. Complete game, random number generator and security testing where required.
8. Register for Remote Gaming Duty with HMRC.
9. establish compliant payment, customer-fund and complaints procedures.
10. Complete a pre-launch compliance review before accepting deposits.

An online casino cannot legally serve consumers in Great Britain simply because its company, servers or gambling licence are based overseas. A Gambling Commission licence is still required when remote gambling is offered to consumers in England, Scotland or Wales.

What Does Opening an Online Casino Actually Involve?

Opening an online casino involves considerably more than purchasing a website template and connecting several slot games.

The operator is taking responsibility for a regulated financial and entertainment service that processes customer identities, deposits, withdrawals and potentially sensitive affordability information.

The business must be capable of meeting the three statutory licensing objectives:

• Keeping crime and disorder out of gambling.
• Ensuring gambling is conducted fairly and openly.
• Protecting children and vulnerable people from harm or exploitation.

The Gambling Commission assesses whether applicants can deliver these objectives before granting a licence and continues monitoring the business after launch.

The operator must therefore build regulatory compliance into its product, management structure, financing, technology and customer service arrangements from the beginning.

Treating compliance as a final website checklist is unlikely to produce an adequate application.

Which Online Casino Licence Is Required?

Remote Casino Operating Licence

A business that contracts directly with customers and provides online casino games will normally require a remote casino operating licence from the Gambling Commission.

This licence covers casino games supplied through websites, mobile applications and other remote communication methods to players in Great Britain.

A business based in Malta, Gibraltar, the Isle of Man or another jurisdiction still needs the appropriate Gambling Commission licence when serving British consumers.

A fully remote operator does not ordinarily need a casino premises licence merely because it runs a website. However, additional licensing questions can arise where physical premises are used to provide gambling facilities to customers.

Is a Gambling Software Licence Also Required?

A separate remote gambling software licence may be required when the business manufactures, adapts, installs or supplies gambling software rather than merely using games supplied by appropriately licensed third parties.

The correct licence structure depends on who owns the software, who hosts the games, who contracts with customers and who controls the gambling transaction. A software developer, game host and consumer-facing casino can therefore require different licence combinations.

What Is a Casino Game Host Licence?

A remote casino game host licence is intended for certain business-to-business operators that host casino games through another licensed operator’s platform but do not contract directly with the players using those games.

It is not a substitute for a full remote casino operating licence where the business holds player accounts, accepts deposits or has the contractual relationship with customers.

Can a White-Label Casino Be Used?

A white-label arrangement allows a brand to use another company’s gambling platform and, in some arrangements, operate under that company’s licence.

It may reduce the technical infrastructure that the brand needs to build. However, it is not an automatic shortcut around suitability checks, source-of-funds scrutiny or consumer protection requirements.

The Gambling Commission states that responsibility for compliance across white-labelled gambling websites remains with the licence holder and cannot be transferred to another party.

Commercial agreements should clearly define responsibility for:

• Customer verification and AML monitoring.
• Safer-gambling interventions.
• Deposits, withdrawals and customer funds.
• Marketing and affiliate activity.
• Complaints and regulatory reporting.
• Game testing and technical incidents.

How to Open an Online Casino Step by Step?

1.Decide Which Market and Casino Products Will Be Offered

The founders must first determine exactly what the casino will offer. Possible products include online slots, roulette, blackjack, baccarat, live-dealer games, poker or other peer-to-peer games.

This decision affects the required licences, software contracts, technical integrations, risk controls and tax treatment. An operator that later adds sports betting, bingo or lottery products may need additional licensed activities.

The proposed market must also be defined. A Gambling Commission licence concerns consumers in Great Britain.

Northern Ireland has a different regulatory position, and the Gambling Commission does not regulate the provision of remote gambling there in the same way. Specialist advice should be obtained before targeting Northern Irish customers.

2.Select an Operating Model

The principal models are:

Proprietary operator: The business holds its own licence, platform agreements and customer relationships.

Turnkey platform: A technology supplier provides the casino platform while the operator holds the consumer-facing licence.

White label: An existing licensed operator supplies much of the infrastructure and assumes formal regulatory responsibility.

Game host or B2B supplier: The business provides casino content to other licensed operators instead of accepting players directly.

The model should be chosen before submitting an application because the Gambling Commission will examine contractual responsibilities, software supply, ownership, funding and the end-to-end customer journey.

3.Establish the Company and Ownership Structure

A UK private limited company can be incorporated online through Companies House. The online incorporation fee is £100 as of July 2026. Companies House identity-verification and corporate-transparency requirements must also be followed.

A UK company is not mandatory in every licensing structure, but the applicant must provide transparent information about its legal entity, controllers, shareholders and ultimate beneficial owners.

A licence application may require:

• Certificate of incorporation and constitutional documents.
• Group and ownership diagrams.
• Details of shareholders and controllers.
• Bank statements and credit reports.
• Evidence showing the legitimate source of investment.
• Financial forecasts and existing accounts.
• Details of loans, investors and profit-sharing agreements.

The Commission looks beyond the applicant company where necessary and can assess ultimate owners, controllers, financiers and other people connected with the proposed operation.

4.Prepare a Detailed Business Plan

The business plan should explain why the licence is being requested, the gambling activities to be offered, the target territories, the source of funding and the company’s medium-term objectives.

It should also demonstrate that the business has enough financial resources to operate compliantly rather than relying on customer deposits or unrealistic early revenue.

The Gambling Commission expects new businesses to supply forecasts and may examine:

• Expected registrations, active customers and GGY.
• Platform, game-provider and payment costs.
• Staffing and outsourcing arrangements.
• Compliance and customer-service resources.
• Marketing expenditure.
• Cash-flow assumptions.
• Customer-fund liabilities.
• Contingency funding and operational resilience.

Applicants for remote casino activities must also submit appropriate anti-money laundering documentation and evidence explaining how their policies support the licensing objectives.

5.Appoint Competent Management and Apply for Personal Licences

People occupying specified management positions may require Personal Management Licences. Relevant functions can include overall strategy, finance, compliance, marketing, information technology and anti-money laundering responsibilities.

The current PML application fee is £370 per person. PML applications should generally be submitted alongside the operating licence application. Some qualifying small-scale operators may instead use Annex A declarations for relevant individuals.

The Commission assesses the identity, finances, integrity, competence and criminal history of applicants and relevant individuals. It also considers whether the team understands the Gambling Act, the LCCP and the practical responsibilities attached to the licence.

6.Build the Compliance Framework Before Applying

The applicant should have operational policies rather than generic documents copied from another casino.

The framework will normally cover:

• Age and identity verification.
• Anti-money laundering and terrorist-financing controls.
• Source-of-funds and source-of-wealth assessments.
• Customer risk profiling.
• Safer-gambling monitoring and interventions.
• Self-exclusion and GAMSTOP.
• Complaints and alternative dispute resolution.
• Customer funds and insolvency disclosures.
• Marketing, bonuses and affiliate oversight.
• Data protection and information security.
• Regulatory returns and key-event reporting.

Remote casino operators are subject to relevant anti-money laundering requirements, the Proceeds of Crime Act and the LCCP. They must be able to recognise suspicious activity, investigate risk and make legally required disclosures.

7.Choose a Compliant Casino Platform and Game Suppliers

The platform must support more than game display and payment processing.

It should provide reliable controls for:

• Player registration and verification.
• Deposit and withdrawal management.
• Self-exclusion and account restrictions.
• Financial and gambling limits.
• Customer-risk alerts.
• Responsible-gambling interactions.
• Bonus and wagering-rule controls.
• Audit trails and regulatory reports.
• Suspicious-activity investigations.
• Marketing preferences and consent records.

Contracts should identify which party is responsible for technical incidents, game fairness, data breaches, rejected payments, duplicate accounts and regulatory reporting.

The operator should verify that suppliers hold every Gambling Commission licence required for the services they provide. Outsourcing technology does not outsource the operator’s regulatory accountability.

8.Complete Technical Testing and Security Work

Remote gambling and gambling software licence holders must comply with the Remote Gambling and Software Technical Standards. These standards cover game behaviour, fairness, security, customer information, financial limits and other technical controls.

Where third-party testing is required, the operator must use a test house approved by the Gambling Commission. Game and random number generator testing must be completed, and satisfactory reports submitted, before the affected game is released for play.

Depending on its activities, the operator may also need periodic games testing and independent security audits. Major software changes affecting fairness can trigger further external testing.

9.Implement Age, Identity and Customer-Risk Checks

A remote operator must obtain and verify information establishing a customer’s identity before allowing that person to gamble. The required information includes, but is not limited to, the customer’s name, address and date of birth.

Operators should not delay checks that could reasonably have been completed earlier until the player requests a withdrawal. Customers should also be told what documents or information may be requested and when.

Safer-gambling controls must operate from the moment an account is opened. Operators need systems that monitor customer activity, identify indicators of harm, take proportionate action and evaluate whether an interaction has worked.

Current rules also require light-touch financial vulnerability checks where a customer exceeds £150 in net deposits during a rolling 30-day period. These checks use publicly available information and are separate from the previously discussed financial-risk-assessment pilot.

10.Configure Deposits, Withdrawals and Player Funds

Remote operators must not accept credit-card payments for gambling. This includes arrangements where a digital wallet could be funded through a credit card unless the payment setup prevents prohibited credit-card gambling.

Operators holding money for customers must comply with customer-fund segregation requirements and clearly explain in their terms:

• Whether the funds are protected if the company becomes insolvent.
• The level of protection provided.
• The method used to provide that protection.
• Customer-fund information must be presented clearly, including when a customer first deposits.

Withdrawal procedures should be designed at the same time as deposit procedures. An operator should not make depositing easy while introducing unnecessary identity or documentation barriers only when a customer tries to withdraw.

11.Register for Remote Gaming Duty

An online casino receiving remote gaming profits from UK customers must register with HMRC and account for Remote Gaming Duty.

The rate increased from 21% to 40% of remote gaming profits on 1 April 2026. The duty applies on a place-of-consumption basis, meaning overseas operators can also owe UK duty on profits generated from UK customers.

Businesses based in the UK and certain listed jurisdictions should generally register at least 14 days before beginning taxable activity. Other overseas businesses are generally required to register at least 31 days before starting.

Returns are normally submitted for quarterly accounting periods, including periods in which no duty is payable. HMRC records should generally be retained for four years.

Remote Gaming Duty is not the only possible tax obligation. Corporation Tax, payroll taxes, transfer pricing, VAT treatment and the Economic Crime Levy may also require professional consideration, depending on the structure and activities of the business.

12.Establish Data Protection and Marketing Controls

An online casino processes substantial amounts of personal and financial-risk information. It must comply with the UK GDPR, the Data Protection Act 2018 and relevant Privacy and Electronic Communications Regulations requirements.

Organisations using personal information usually need to pay the ICO data protection fee unless an exemption applies. Marketing by email, text and social-media direct message may require consent or another valid route permitted by PECR.

Since 1 May 2025, online gambling customers must be offered marketing preferences based on both the product type and communication channel. A single general marketing tick box is not sufficient for this Gambling Commission requirement.

Gambling advertisements must be socially responsible. They must not exploit vulnerable people, suggest gambling is a solution to financial problems or contain material with strong appeal to under-18s.

These responsibilities extend to social-media content, affiliates and marketing agencies acting for the operator.

13.Design Bonuses Under the Current Rules

Since 19 January 2026, wagering requirements attached to promotional bonus funds cannot exceed ten times the bonus amount.

An individual incentive must also not combine more than one type of gambling product, such as requiring a customer to use both sports betting and casino products as part of the same promotion. Bonus terms must be clear, fair, transparent and readily accessible.

For example, a £10 casino bonus cannot have a wagering requirement above £100. The operator must still explain game weighting, expiry periods, withdrawal conditions and excluded games clearly rather than relying on the maximum limit alone.

14.Provide Self-Exclusion, Financial Limits and Complaints Procedures

Online operators must provide their own self-exclusion arrangements and participate in applicable multi-operator self-exclusion requirements, including GAMSTOP for online gambling.

Since 31 October 2025, customers must be prompted to set a financial limit before making their first deposit.

Further rules requiring online operators to provide a clearly defined gross deposit limit are scheduled to take effect on 30 September 2026, following an extension from the original June implementation date.

The casino must also operate a fair and accessible complaints process. Where an eligible dispute cannot be resolved internally within eight weeks, the customer must be able to refer it free of charge to an approved alternative dispute resolution provider.

How Much Does It Cost to Open an Online Casino?

There is no reliable single figure covering every online casino launch. The Gambling Commission licence fee is only one element of the budget.

The principal cost areas include:

• Operating and personal licence applications.
• Gambling solicitors and regulatory consultants.
• Platform setup and recurring hosting charges.
• Game aggregation and revenue-share agreements.
• Testing, certification and security audits.
• KYC, AML and fraud-screening services.
• Payment processing and financial reserves.
• Compliance, customer service and technical staff.
• Data protection and cybersecurity.
• Marketing, affiliation and customer acquisition.
• Remote Gaming Duty and other business taxes.

Practical Licence-Fee Example

Suppose an applicant submits a remote casino licence application before 1 October 2026 and forecasts annual GGY of £300,000.

Under the current bands, it falls within the category for annual GGY below £550,000:

• Application fee: £4,224.
• Annual fee: £4,199.

From 1 October 2026, projected GGY of £300,000 falls within the new band of £250,000 to below £875,000:

• Application fee: £14,483.
• Annual fee: £12,375.

This illustrates why application timing and accurate GGY forecasts can materially affect regulatory fees. The Commission may also examine whether projections are commercially credible.

How Long Does an Online Casino Licence Application Take?

The Gambling Commission does not provide one guaranteed processing period for every operating licence application.

Applications are complex, and the time required depends on the business model, ownership structure, funding arrangements, management team and quality of the supporting documents.

Processing does not begin until the required fee has been paid and the application is complete. A caseworker may provide a more specific estimate after reviewing the submitted material.

A prospective operator should allow substantial preparation time before applying. Submitting an incomplete application can cause delay, rejection and loss of the non-refundable application fee.

Pre-Launch Online Casino Checklist

Before accepting registrations or deposits, the operator should confirm that:

• The correct operating and personal licences have been issued.
• Every live domain and trading name is included on the licence where required.
• All games and RNGs have completed applicable testing.
• Age and identity checks work before gambling begins.
• AML alerts and escalation procedures have been tested.
• GAMSTOP and internal self-exclusion controls operate correctly.
• Deposit, financial and session-management tools are available.
• Credit-card deposits cannot be accepted.
• Customer funds are segregated and correctly disclosed.
• Bonus rules comply with the ten-times limit.
• Marketing preferences are separated by product and channel.
• Complaints and ADR information are accessible.
• HMRC registration is complete.
• Privacy, cookie and direct-marketing controls comply with data protection law.
• Staff understand incident and regulatory reporting procedures.

A documented pre-launch test should follow the complete customer journey, including failed verification, deposit rejection, self-exclusion, risk alerts, account suspension, withdrawal, complaint and data-access scenarios.

Final Takeaway

Opening an online casino in the UK is a regulated business launch rather than a standard website project.

The operator must prove that its owners and managers are suitable, its funding is legitimate, its games are fair, its technology is secure and its systems protect customers from crime and gambling-related harm.

It must also maintain compliant payments, marketing, bonuses, tax records, customer-fund arrangements and complaints procedures after launch.

The most effective approach is to design the business around the Gambling Commission’s licensing objectives from the outset.

A platform or white-label partner can supply technology, but it cannot replace competent management, adequate financial resources or genuine regulatory accountability.

Before committing significant capital, prospective operators should obtain specialist gambling-law, compliance and tax advice and check the latest Gambling Commission requirements, particularly the new licence fee bands taking effect on 1 October 2026.

Frequently Asked Questions

Can an individual open an online casino in the UK?

An individual aged 18 or over can apply for an operating licence, but the person must demonstrate suitable finances, integrity, competence and regulatory arrangements.

Most substantial operations use a corporate structure because of investment, liability, staffing and governance requirements.

Does an online casino need a UK company?

A UK-incorporated company is not the only possible structure. An overseas business can apply, but it still needs a Gambling Commission licence to serve consumers in Great Britain and must satisfy UK regulatory and tax requirements.

Can an online casino operate without a Gambling Commission licence?

It cannot legally provide remote casino gambling to consumers in Great Britain without the required operating licence. Advertising a remote gambling business to British consumers can also bring it within the UK regulatory framework.

Are online casino players required to be verified?

Yes. The operator must verify information establishing the player’s identity before permitting the customer to gamble. Verification must include the name, address and date of birth, although additional evidence may be needed.

Can an online casino accept credit cards?

No. Remote gambling operators covered by the rule must not accept credit-card payments for gambling. Payment and wallet arrangements must also prevent indirect circumvention of the prohibition.

What is the tax rate for a UK online casino?

Remote Gaming Duty is charged at 40% of remote gaming profits from 1 April 2026. Other taxes and levies may apply according to the company’s location, structure, employees and activities.

What are the maximum stakes for online slots?

The maximum stake per game cycle is £2 for customers aged 18 to 24 and £5 for customers aged 25 or over. These limits apply to online slots rather than every type of online casino game.

Can an online casino use affiliates?

Yes, but the licensed operator remains responsible for ensuring affiliate advertising complies with the LCCP and advertising rules. Affiliates must not expose unverified users to playable free versions of real-money games where age verification is required.

Can the casino launch while the licence application is pending?

An applicant should not provide licensable remote casino facilities to consumers in Great Britain until the required licence has been granted and all applicable technical, tax and operational requirements have been satisfied.
