Unlawful Estate Agency Businesses: HMRC Registration and Money Laundering Rules

Unlawful estate agency businesses can face serious consequences if they operate without the required anti-money laundering registration or fail to comply with the Money Laundering Regulations. For estate agents, compliance is not simply an administrative requirement. Property transactions can expose businesses to significant money laundering, terrorist financing and proliferation financing risks, which is why HMRC requires relevant estate agency businesses to operate under appropriate supervision. This guide explains what makes an estate agency business subject to the rules, how the Estate Agents Act 1979 connects with the Money Laundering Regulations, when an estate agent needs to register with HMRC, what an estate agents register UK search can tell you, the compliance responsibilities that apply after registration, the risks HMRC currently identifies in the property sector, and what can happen when an estate agency business fails to comply.

What Makes Unlawful Estate Agency Businesses Subject to HMRC Enforcement?

An estate agency business can operate unlawfully from an anti-money laundering perspective if it carries out regulated estate agency activity without the required registration or continues trading after its HMRC registration has been cancelled. HMRC states that it is a criminal offence to trade as an estate agency business without being registered with HMRC for money laundering supervision, where registration is required. This means an estate agent cannot simply begin carrying out regulated activities and arrange registration later. HMRC’s registration guidance requires relevant businesses to register before carrying on any activity as an estate agency business. However, unlawful operation is not limited to registration. An estate agency business can also face enforcement action where it is registered but fails to meet its ongoing obligations under the Money Laundering Regulations. These obligations include areas such as:

• carrying out appropriate customer due diligence;
• maintaining an appropriate business risk assessment;
• having suitable policies, controls and procedures;
• keeping required records;
• identifying and managing higher-risk situations;
• complying with suspicious activity reporting requirements; and
• keeping its compliance arrangements appropriate for the size and nature of the business.

What Are the Estate Agents Act 1979 and Money Laundering Regulations?

The Estate Agents Act 1979 is important when determining what constitutes estate agency work for anti-money laundering supervision purposes. Under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017, the definition of an estate agent is linked to estate agency work as defined under section 1 of the Estate Agents Act 1979. This connection matters because a business does not necessarily avoid the anti-money laundering rules simply by describing itself as a property consultant, property finder or another type of property business. The activities actually carried out can determine whether the business falls within the definition.

What Is Estate Agency Work?

Estate agency work generally involves acting on instructions from a customer who wants to acquire, dispose of or otherwise deal with an interest in land, or introducing that customer to another person for that purpose. Examples of activities that can fall within the definition include:

• sending property details to prospective buyers or sellers;
• arranging property viewings;
• providing personal advice to prospective sellers or buyers;
• answering questions from potential buyers or sellers;
• passing information between parties;
• providing or arranging an Energy Performance Certificate;
• providing property valuations;
• preparing property plans or taking property photographs; and
• providing a for-sale board containing the estate agency business’s contact details.

The important point is that the nature of the activity matters more than the label used by the business.

Which Businesses Need to Register With HMRC?

Not every business involved in property needs to register as an estate agency business. The requirement depends on the activities being carried out. Businesses that may fall within the estate agency rules include:

• high street residential estate agencies;
• commercial estate agencies;
• online estate agencies;
• property and land auctioneers;
• land agents;
• relocation agents and property finders;
• private acquisition specialists;
• sub-agents providing estate agency services;
• asset management businesses that also provide estate agency services;
• business brokers or transfer agents in relevant circumstances;
• social housing associations offering estate agency services; and
• letting or property management agents where they also provide estate agency services.

The requirement should therefore be considered based on the actual services provided rather than simply the name used by the business.

Do online estate agents have to register?

An online business is not automatically outside the rules because it does not operate from a traditional high street office. Online estate agencies can fall within the registration requirements where their activities amount to estate agency work under the relevant legislation.

Do property finders need to register?

Potentially, yes. Property finders, relocation agents and private acquisition specialists can fall within the estate agency definition depending on the services they provide. If your business introduces clients to property opportunities or acts on instructions connected with acquiring or disposing of an interest in land, you should establish whether the activity falls within the statutory definition before trading.

When Must an Estate Agency Business Register With HMRC?

If your business is within the estate agency definition and HMRC is the appropriate supervisor, you must register before carrying out regulated estate agency activity. Registration should therefore be dealt with before the business begins providing regulated services rather than after trading has already started. This is particularly important for newly established estate agents. Regulatory obligations should be identified during the business setup process so that the necessary registration and compliance arrangements are in place before clients are accepted.

How to Check the Estate Agents Register UK

If you want to check whether an estate agency business is registered for HMRC money laundering supervision, you can use the HMRC Supervised Business Register. The register can provide information about businesses supervised by HMRC for money laundering purposes, including details such as:

• the business registration number;
• the registered business name;
• the trading name;
• the first part of the postcode;
• the date the business became supervised; and
• the sectors for which the business is registered.

There can be a delay before a newly registered business appears on the public register. Therefore, an estate agent not immediately appearing on the register should not automatically be treated as evidence that the business is deliberately operating unlawfully.

What Happens to Unlawful Estate Agency Businesses If an Estate Agent Does Not Register?

Operating an estate agency business without the required HMRC registration can result in enforcement action. HMRC states that trading as an estate agency business without registration, or continuing to trade after registration has been cancelled, is a criminal offence. HMRC can also impose financial penalties for failures relating to registration. When deciding the appropriate enforcement response, HMRC can consider factors such as the reason for the failure, whether the business disclosed the failure itself, whether HMRC discovered the issue and whether previous warnings or penalties have been issued.

HMRC Enforcement Against Unlawful Estate Agency Businesses

HMRC has previously taken enforcement action against estate agency businesses that failed to comply with anti-money laundering requirements. In October 2022, HMRC announced that 68 estate agents had been fined a combined £519,645 for breaches of the money laundering regulations. The announcement also referred to the first prosecution of an estate agent for trading while unregistered. This figure is a historical enforcement example and should not be presented as the current total of estate agency penalties. HMRC continues to publish information about businesses that have failed to comply with the Money Laundering Regulations, including estate agency businesses that have received penalties for registration and other compliance failures.

What Are the Current Money Laundering Risks for Estate Agents?

Property remains an important money laundering risk area in the UK. HMRC’s current sector risk assessment identifies property as a higher-risk area for money laundering. Estate agents are among the property-sector businesses with significant exposure to these risks. This is why estate agency businesses need a risk-based approach rather than treating every customer and transaction as presenting the same level of risk.

Complex company structures

One significant risk involves property purchases through complex corporate structures or trusts, particularly where it is difficult to establish who ultimately owns or controls the property or funds. Structures involving overseas entities or secrecy jurisdictions can make ownership and source-of-funds checks more difficult and may require greater scrutiny.

Unusual source of funds

The source of funds should be considered in the context of the customer’s circumstances and the proposed property transaction. For example, where a customer’s apparent financial position does not reasonably explain a substantial property purchase, the circumstances may require additional investigation and risk assessment.

Unexpected payments and refunds

Unexpected payments, substantial overpayments, split payments or requests for money to be returned to a different person or account can create additional money laundering risks. These circumstances should not automatically be treated as criminal activity, but they can represent warning signs that require appropriate consideration under the business’s AML procedures.

Third-party payments

Estate agents should pay attention where someone other than the customer makes payments connected with a transaction without a clear and legitimate explanation. Unexplained third-party payments, particularly where combined with other risk indicators, may require enhanced scrutiny.

Why Property Transactions Are Attractive to Criminals

Property can be attractive for money laundering because large amounts of money can move through individual transactions and ownership can sometimes be obscured through corporate structures, trusts or other arrangements. Potential methods identified by HMRC include:

• buying property using proceeds of crime;
• using property transactions to create an apparently legitimate source for criminal funds;
• using complex corporate structures or trusts to obscure beneficial ownership;
• using unusual deposits or payment arrangements;
• using property transactions connected with mortgage fraud; and
• using property to facilitate other criminal activity.

Property transactions can also be associated with wider financial crime risks, including fraud, corruption, sanctions evasion and organised criminal activity.

What Anti-Money Laundering Checks Must Estate Agents Carry Out?

Registration with HMRC is only the starting point. An estate agency business must also comply with the relevant requirements of the Money Laundering Regulations. The precise controls required will depend on the business and its risk profile, but the compliance framework generally includes:

• customer due diligence;
• risk assessment;
• policies, controls and procedures;
• record keeping;
• ongoing monitoring where required;
• enhanced due diligence for higher-risk situations;
• identification and escalation of suspicious activity; and
• appropriate staff awareness and training.

Estate agency businesses should ensure their AML procedures are proportionate to their activities while still addressing the risks identified within the business.

Estate Agency Business Risk Assessment

An estate agency business should not rely on a generic risk assessment that has no meaningful connection with how it actually operates. The business should consider factors including:

• its customers;
• the countries and geographical areas in which it operates;
• the estate agency services it provides;
• the size, nature and frequency of transactions;
• how services are delivered; and
• how the business interacts with customers.

The resulting risk assessment should be kept up to date and should reflect changes to the business model, services and operating arrangements.

When should the risk assessment be updated?

The risk assessment should not be treated as a document that is prepared once and then forgotten. If an estate agency starts providing new services, changes the way it operates, enters new markets or changes its customer base, the risk assessment and related policies should be reviewed and updated. New technology, changes to customer onboarding, new payment methods and changes in the geographical areas served can also affect the risk profile of the business.

What Is Customer Due Diligence for Estate Agents?

Customer due diligence, commonly referred to as CDD, is a central part of anti-money laundering compliance. It is designed to help an estate agency establish who its customer is, understand the nature and purpose of the relationship and identify situations where additional checks may be necessary. For property transactions, this is particularly important because the apparent customer may not always be the person who ultimately owns or controls the funds or property.

Why beneficial ownership matters

Where a company or trust is involved, the estate agent may need to establish who ultimately owns or controls the relevant entity. Complex or opaque ownership structures can increase the risk that the true beneficial owner is difficult to identify. The estate agent should therefore follow its risk-based procedures and carry out additional checks where required.

When Is Enhanced Due Diligence Required?

Higher-risk circumstances can require enhanced due diligence. Potential risk factors can include:

• connections with higher-risk jurisdictions;
• complex or opaque ownership structures;
• unusual sources of funds;
• transactions without an obvious commercial purpose;
• unexpected third-party payments;
• cash or foreign currency payments;
• politically exposed persons in higher-risk circumstances; and
• other significant risk indicators identified through the business’s risk assessment.

Where a higher level of risk is identified, the business should apply appropriate additional measures rather than proceeding as though the transaction presents ordinary risk.

What If an Estate Agent Suspects Money Laundering?

An estate agency business should not ignore a transaction simply because it has already been agreed or because the customer is commercially important. Where the business knows or suspects that a person is engaged in or attempting money laundering or terrorist financing, the relevant reporting obligations need to be considered. Estate agency businesses should follow the applicable HMRC and National Crime Agency requirements when dealing with suspected suspicious activity and should ensure that employees understand how concerns are escalated internally.

What Penalties Can Unlawful Estate Agency Businesses Face?

HMRC has a range of enforcement powers when an estate agency business breaches the Money Laundering Regulations. Depending on the nature and seriousness of the breach, HMRC may impose financial penalties or take other regulatory action. Serious cases can also lead to criminal investigation. Following prosecution and conviction, breaches can result in an unlimited fine and/or imprisonment for up to two years. Financial penalties can arise from failures including:

• failure to register for supervision;
• inadequate customer due diligence;
• failure to maintain appropriate policies and controls;
• inadequate record keeping;
• failure to carry out an appropriate risk assessment; and
• other breaches of the Money Laundering Regulations.

HMRC Sanction Administration Charge

There is also an important recent development for businesses dealing with HMRC anti-money laundering sanctions. From 1 December 2025, HMRC extended its sanction administration charge to cover civil sanctions issued for failures to comply with the Money Laundering Regulations. A £2,000 sanction administration charge can apply in addition to the financial penalty for specified breaches, subject to the applicable rules and caps. This makes it particularly important for estate agency businesses to treat AML compliance as an ongoing business responsibility rather than a one-off registration exercise.

Can HMRC Cancel an Estate Agency Registration?

Yes. HMRC can take regulatory action against businesses that fail to comply with their obligations, including cancelling registration in appropriate circumstances. Continuing to trade as an estate agency business after registration has been cancelled can create further legal and regulatory consequences. Businesses should therefore respond promptly to HMRC compliance concerns and maintain their registration requirements.

Do Letting Agents Have the Same Requirements?

Letting agency businesses have separate anti-money laundering requirements, although a business can carry out both estate agency and letting agency activities. A letting agency business can fall within the Money Laundering Regulations where it meets the relevant statutory conditions, including the rules concerning monthly rent and tenancy periods. Where a business carries out both letting agency and estate agency activities, it needs to consider the requirements applicable to each activity rather than assuming that registration for one automatically covers every service it provides.

What About Commercial Estate Agents?

Commercial estate agency businesses can also fall within the estate agency anti-money laundering requirements. Commercial estate agents should assess their activities against the statutory definition and establish whether HMRC registration is required. Commercial property transactions can involve complex ownership arrangements, corporate structures and substantial sums of money. These factors can increase the importance of effective customer due diligence and transaction risk assessment.

Are Property Portals Required to Register?

Not necessarily. A property portal may not need estate agency registration where it merely allows private sellers to advertise properties and buyers and sellers to contact each other, provided it does nothing else that falls within the general definition of estate agency work. The distinction is therefore based on what the business actually does rather than simply whether it operates online.

What Should a New Estate Agency Do Before Trading?

If you are establishing a new estate agency business, AML compliance should be addressed before you begin regulated activity.

1. Establish whether you are an estate agency business

Review the actual services you intend to provide against the Estate Agents Act 1979 and the Money Laundering Regulations.

2. Identify the correct supervisor

Establish which organisation is responsible for supervising the relevant activity. HMRC supervises relevant estate agency businesses for anti-money laundering purposes.

3. Register before trading

If HMRC registration is required, complete the registration before carrying out regulated estate agency activity.

4. Prepare your risk assessment

Identify the money laundering, terrorist financing and proliferation financing risks arising from your customers, services, locations, transaction types and operating model.

5. Put policies and controls in place

Your policies should explain how the business will identify customers, assess risk, carry out appropriate checks, maintain records and deal with suspicious activity.

6. Train relevant staff

Employees and other relevant people involved in regulated activity should understand their AML responsibilities and know when concerns need to be escalated.

7. Keep the system under review

AML compliance should evolve as the business changes. New services, new customer types, new geographical markets and changes to transaction patterns can all introduce additional risks.

Estate Agency AML Compliance Checklist for 2026/27

For an estate agency business operating in the 2026/27 financial year, the following checklist provides a practical starting point:

• Confirm whether the business falls within the definition of an estate agency business.
• Check whether HMRC is the appropriate AML supervisor.
• Register before carrying out regulated estate agency activity.
• Check the business’s entry on the HMRC Supervised Business Register where appropriate.
• Prepare and maintain a written business risk assessment.
• Consider money laundering, terrorist financing and proliferation financing risks.
• Identify customer and beneficial ownership risks.
• Apply customer due diligence procedures.
• Apply enhanced measures where higher risk is identified.
• Maintain appropriate policies, controls and procedures.
• Keep required records.
• Monitor transactions and customer relationships where required.
• Understand suspicious activity reporting obligations.
• Review the risk assessment when the business changes.
• Pay HMRC supervision and renewal fees when due.
• Respond promptly to HMRC compliance enquiries.
• Do not continue regulated activity if HMRC registration has been cancelled.

Final Thoughts on Unlawful Estate Agency Businesses and Estate Agency Compliance

The rules affecting unlawful estate agency businesses have become increasingly important as HMRC continues to strengthen its approach to anti-money laundering supervision. For an estate agency operating in 2026/27, the key issue is not simply whether the business appears on the register. It is whether the business has correctly identified its regulatory obligations and maintains an effective compliance framework in practice. That means understanding the Estate Agents Act 1979, determining whether the business falls within HMRC’s definition of an estate agency business, registering before regulated activity begins, maintaining a current risk assessment, carrying out appropriate customer due diligence and responding properly when a transaction presents higher-risk indicators. Property remains a significant money laundering risk area. Complex ownership structures, unusual sources of funds, unexplained third-party payments and transactions without an obvious commercial purpose can all require closer attention. For estate agency businesses, effective AML compliance is therefore not simply about avoiding a fine. It is about preventing the business from being used to facilitate financial crime and being able to demonstrate that appropriate systems are operating when HMRC reviews the business.

Case Study: Helping an Estate Agent Understand the Risks of Unlawful Estate Agency Activity

A property professional contacted our Fulham Broadway office by email after becoming concerned about whether the way their business was operating could fall within the requirements of the Estate Agents Act 1979. They had been carrying out property-related activities for clients but were unclear about when an estate agency business becomes subject to the legislation, what registration and compliance obligations could apply, and what could happen if those requirements were overlooked.

During our discussion, we reviewed the nature of the business and the activities it was undertaking. We explained that being involved in property transactions does not automatically mean every business is treated in exactly the same way, so the specific activities and role performed for clients need to be considered carefully. We also discussed the importance of understanding the distinction between legitimate estate agency activity and arrangements that could potentially result in an unlawful estate agency business.

The business owner was particularly concerned about compliance risks and whether existing arrangements needed to be changed. We discussed the relevant requirements around operating an estate agency business, maintaining appropriate records and understanding the regulatory framework before continuing with activities that could fall within the legislation.

As part of the wider review, we also considered the financial and tax side of the business. This included discussing business accounting, bookkeeping, VAT where applicable and the importance of maintaining clear financial records alongside regulatory compliance. The aim was to make sure the owner was not looking at the estate agency requirements in isolation, but understood how regulatory and accounting responsibilities fit together.

We then helped the client identify the areas that required further attention and explained why professional advice should be obtained where the precise nature of an estate agency activity or legal obligation is unclear. This gave the business owner a clearer understanding of the risks involved and the practical steps needed to review their current arrangements.

By the end of the discussion, the client had a better understanding of the importance of complying with the applicable estate agency requirements and maintaining proper business records. The review also helped them identify areas where their existing processes needed closer attention, allowing them to take a more proactive approach rather than waiting for a regulatory issue to arise.
