The process of finding, securing and moving into your new house can take many months to complete, with there being several stages you need to complete before you can make the property your home. AML checks are just one of these checks.

But if you’re hopeful to soon be a homeowner and are looking for the AML checks you need when buying a house, then read on.

What Are AML Checks?

Anti-money laundering checks (or AML checks) are measures put in place to prevent illicit money laundering activities from taking place. These checks take the form of various customer verification processes, transaction monitoring solutions and more to ensure that your customer is maintaining good financial practices. These checks are a legal requirement for businesses across the world.   

Why Are AML Checks Important?

AML checks are crucial for identifying financial crime, criminal organisations and terrorist financing, helping the government’s efforts to combat corruption. According to estimates from the National Crime Agency (NCA), £10 billion of illegal money is laundered each year in the UK, making robust AML processes crucial to protect the health of the country’s economy. 

 

The property market is a prime target for criminals looking to disguise the moving of large funds, since the industry sees vast sums of cash being transferred on a regular basis. AML checks when buying a house are, therefore, necessary for estate agents and other parties to identify potential illicit companies and financial criminals, protecting the solidity of the UK economy and the legitimacy of their own business in the process.  

The Mandatory AML Checks When Buying A House 

Thankfully for house-hunters who want to get the process completed as quickly and efficiently as possible, you’ll be pleased to hear that the AML checks when buying a house aren’t complex and usually only take a matter of weeks to be completed. Essentially, the process involves three steps: identity verification, address verification, and a proof of funds check (to make sure that the funds you will be using were gained legitimately). 

Identity Verification


First things first, the estate agent will need to carry out an identity verification check. This check is performed simply to ascertain whether the buyer is exactly who they claim to be. The process of identity verification is straightforward and involves three steps. 

 

  • Checking whether the individual is legitimate.
  • Checking whether the individual is the person they claim to be. 
  • Making sure the individual is not part of any criminal activity.  

What counts as proof of identity?

Identity can be verified with a range of valid documents. Making sure you have one of the following documents ready ahead of time will also help to streamline the AML process. 

 

  • A valid passport.
  • A valid UK driving licence. 
  • A birth certificate. 
  • National Identity Card with a valid photo. 
  • Benefit book.

 

While each of these forms of identification is valid, they don’t cover each and every document that can be used. To find a full list of documents that can legally validate proof of identity, visit the government website.

Address Verification


Verifying a customer’s address is an essential part of the KYC process that must be completed by estate agents before an individual can buy a house. Doing this helps companies to assess the potential risk of a buyer, with addresses linked with suspicious organisations and shell companies being examples of red flags that should be investigated with the necessary enhanced due diligence (EDD) measures. 

 

Documents that can be used for address verification include:

 

  • A utility issued within the last three months.
  • A local authority tax bill from the current year.
  • Electoral Register entry
  • Bank, Building Society or Credit Union statement issued within the last three months. 

 

Proof of Funds Check


While a proof of funds check won’t be required while you’re in the early stages of house-hunting, it will be required once you put in an offer. Simply put, this check makes sure that an individual has the necessary funds to complete the relevant purchase of the property. Proof of funds checks can be completed by providing any of the following documents: 

 

  • If buying with a mortgage - bank statements of the deposit amount. 
  • If buying with cash  - the bank statements of the necessary funds. 
  • An agreement for a mortgage in principle.
  • A statement from a savings or investment account. 

 

A source of funds check is often part of the very same process, with this procedure evaluating whether the money has been obtained from a legitimate place. Documents that can be used in a source of funds check include: 

 

  • Proof of sale - if funds from a previous sale are being used to purchase your current property. 
  • If using inherited money - evidence that this money has been legally obtained.
  • Proof that you’ve sold shares - if you’re using this in the purchase process.
  • Evidence of gambling or lottery winnings - if you’re using this in the purchase process.

What Are The Consequences of Failing an AML Check?

Thankfully, if you fail an AML check, the consequences aren’t severe. More often than not, your buying process will be paused and you will simply be asked to provide further information about your identity, address or proof of funds. However, if illicit activity is suspected, a suspicious activity report (SAR) will be filed against you with the NCA and your transaction could be delayed indefinitely.
