If you buy, sell, let or manage property in the course of business, you are almost certainly an "estate agency business" or "letting agency business" under the Money Laundering Regulations — and HMRC is your AML supervisor. That means registering before you trade, holding a written risk assessment and policies, appointing a nominated officer, and training your staff. Get it wrong and the penalties are real, recent and four-to-six figures. The reassuring part: the documents HMRC checks first are a finite, knowable set — and once they're in place, you stay ready.
- In HMRC's latest enforcement data (penalties published Feb 2026, covering Apr–Sep 2025) agents received 369 penalties totalling £1.88m — estate agents were the worst sector with 170 penalties worth £835,842.
- Over 90% of penalties are for trading while unregistered — you must register with HMRC before you start, and the review can take up to 45 days.
- The core documents: a written risk assessment (Reg 18), policies, controls & procedures (Reg 19–21), a named nominated officer / MLRO, customer due diligence records (Reg 28) and staff training logs.
- Since 1 Dec 2025 a £2,000 sanctions-admin charge is added on top of civil penalties, and directors can be named personally (Reg 78).
Do estate and letting agents need AML supervision?
Yes. Estate agency work and letting agency work (for tenancies at or above the regulated rent threshold) are "relevant persons" under the Money Laundering Regulations 2017. You must register with HMRC as your anti-money-laundering supervisor before you carry out that work — registration is not optional and not automatic. HMRC's own data shows the single biggest cause of penalties is firms trading before they were registered, so this is the first thing to get right.
Why agents get fined — what HMRC checks first
The penalty data tells you exactly where the risk is. In order, the most common failures are:
- Trading while unregistered (Reg 56) — over 90% of all penalties. Register first, trade second.
- Customer due diligence (Reg 28) — failing to identify and verify the people you act for.
- Policies, controls & procedures (Reg 19–21) — not having them written down, or not following them.
- Risk assessment (Reg 18) — no written, business-specific assessment of your money-laundering risk.
Notice the pattern: HMRC isn't looking for heroics. It's looking for the basic, documented system every agent is supposed to run — registered, risk-assessed, written down, evidenced.

Frequently asked questions
Do letting agents need AML registration too?
Letting agency businesses are in scope where they let property at or above the regulated monthly rent threshold. If that's you, you must register with HMRC and meet the same core obligations as sales agents, including sanctions screening.
How long does HMRC AML registration take?
HMRC says its review can take up to 45 days, and you must not carry out estate or letting agency work until you are registered. Don't leave it to the last minute — trading while unregistered is the single most-fined failure.
What's the most common reason agents get fined?
Trading before registering — over 90% of penalties. After that: weak or missing customer due diligence, no written policies and controls, and no business-specific risk assessment.
Can I write these documents myself?
Yes — there's no rule that says you must pay a consultant. You need a written risk assessment, policies and procedures, a nominated officer and training, all specific to your business. Our editable pack gives you that structure to tailor; many firms simply don't realise the set is finite and knowable.
