HMRC AML Supervision for Property Sourcers: A 2026 Guide

Do property sourcers need HMRC AML supervision? In most cases, yes — and you must hold it before you start trading. If you introduce, market or arrange the sale or letting of property for or on behalf of someone else, you are almost certainly carrying on estate agency or letting agency business under the Money Laundering Regulations 2017, and that activity must be supervised. This guide explains who is caught, what the regulations require, how registration works, what customer due diligence looks like in practice, and why sourcing before you are supervised is not a paperwork lapse but a criminal offence.

This is general information, not financial, legal or tax advice — seek independent professional advice.

Who must register for HMRC AML supervision?

The test is not what you call yourself; it is what you actually do. HMRC looks at the substance of the activity. A few common scenarios make the line clearer:

• You source deals and introduce them to investors for a fee. You are acting for others in connection with property transactions — this is within scope and needs supervision.
• You operate a "deal packaging" or sourcing service. Packaging and selling on opportunities to third parties is the kind of activity the regulations are designed to capture.
• You market or arrange lettings on behalf of landlords. Letting agency business above the relevant rent threshold is separately within scope.
• You only ever buy with your own money, for your own portfolio, and never act for anyone else. A pure principal investor may sit outside the estate-agency definition — but the moment you introduce or arrange for a third party, the position changes. Take your own advice on your exact model.

One more point that trips people up: if another supervisor already covers your activity — for example the FCA, or a professional body for certain regulated work — you register with that body rather than HMRC. For the typical standalone property sourcer with no other supervisor, HMRC is the default. If you are unsure which supervisor applies to you, check the position before you trade rather than after.

What the Money Laundering Regulations 2017 actually require

The Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017 — MLR 2017 — set the baseline obligations for every supervised business. They are not a one-off form; they are an ongoing operating standard. The core duties are:

• Register and stay registered with the correct supervisor before carrying on the regulated activity.
• Carry out a written risk assessment of the money-laundering and terrorist-financing risks your business faces, covering customers, geography, products and delivery channels.
• Have written policies, controls and procedures proportionate to that risk, and review them.
• Apply customer due diligence (CDD) — identify and verify customers and beneficial owners, and understand the purpose of the relationship.
• Appoint the right people — including, where applicable, a nominated officer (often called a money laundering reporting officer) to receive and assess internal reports.
• Keep records of your checks and decisions, generally for five years.
• Report suspicious activity to the National Crime Agency where the law requires it, and never "tip off" the subject.
• Train staff so the people doing the work understand the risks and the procedures.

The thread running through all of this is documentation. A supervisor's first question in any inspection is rarely "did something go wrong?" — it is "show me your risk assessment, your policies, and the records of the checks you ran." A firm that cannot produce those is non-compliant even if no dirty money ever touched it.

The HMRC registration process, fees and timeline

Registration is done online and follows a fairly predictable path. Below is the shape of it; always confirm the current detail on gov.uk because HMRC updates the process and the fees from time to time.

The steps

1. Set up a Government Gateway account for the business and sign in to the AML registration service.
2. Declare the business type — for a sourcer this is usually estate agency business, and letting agency business too if you arrange lettings.
3. Provide business and people details — the legal entity, premises, beneficial owners, officers and managers (the "responsible persons").
4. Pass the fit-and-proper test / approval checks. Estate agency businesses must pass a fit-and-proper test; other responsible persons go through an approval check. HMRC assesses honesty, integrity and any relevant convictions.
5. Nominate your compliance roles where required, including the nominated officer.
6. Pay the fees — see below — and submit.
7. Wait for confirmation. Do not begin regulated activity until HMRC tells you the registration is in place.

What it costs

HMRC charges a recurring annual premises fee, plus a one-off fit-and-proper test fee for sectors (including estate agency) that require it, and an approval check fee for each responsible person. Because these figures are reviewed periodically, treat the published rate on the gov.uk fees page as the source of truth at the time you apply. Budget for it as an annual cost, not a single payment.

The timeline trap

HMRC aims to process most applications in around 45 days, but fit-and-proper queries, missing documents or busy periods can push it out. The mistake to avoid is assuming you can "start now and register in the background." You cannot. Carrying on the regulated activity before registration is confirmed is itself the offence. Plan your launch around the registration date, not the application date.

CDD and KYC: what supervised due diligence looks like

In practice, a supervised sourcer applies CDD across everyone in the chain — investors, sellers, and the people behind any corporate party. The typical components are:

• Identity verification: name, date of birth and address checked against reliable, independent documents or electronic data.
• Beneficial ownership: identifying the individuals who ultimately own or control a company or structure, not just the front-facing director.
• Source of funds: understanding where the money is coming from, with stronger evidence required as risk rises.
• Sanctions and PEP screening: checking parties against sanctions lists and identifying politically exposed persons, who attract enhanced scrutiny.
• Enhanced due diligence (EDD): additional checks for higher-risk situations — unusual structures, high-risk jurisdictions, or anything that does not add up.
• Ongoing monitoring: keeping the picture current and re-checking as relationships and transactions change.

Done properly, this is slower than a handshake-and-go introduction. That is the point. The friction is what protects the legitimate parties on both sides of a deal.

Why sourcing without supervision is a criminal offence

This is the part that turns AML from an administrative chore into a hard gate. Under MLR 2017, carrying on estate agency or letting agency business while you are required to be registered, but are not, is a criminal offence. The consequences are not theoretical:

• Financial penalties imposed by HMRC, scaled to the seriousness and duration of the breach.
• Publication of non-compliance — HMRC names businesses that have breached the regulations, which is a reputational hit that outlasts the fine.
• Prosecution in the most serious cases, which can carry an unlimited fine and up to two years' imprisonment.

There is a deeper commercial point too. An investor or seller who later discovers they transacted through an unsupervised firm has every reason to question every other corner that firm may have cut. Supervision is not just a legal requirement; it is the first piece of evidence that a firm takes the rest of its obligations seriously. That is why a credible operator treats registration as something that must be cleared before trading — not raced to catch up with afterwards.

What AML-supervised firms do differently

Two firms can both call themselves "property sourcers" and operate in completely different worlds. Here is the practical contrast.
