UK’s Fight Against Dirty Money: New Rules You Need to Know

The UK has been updating its financial crime laws since 2017 to stop criminals from hiding dirty money. The latest version of these rules, called the Money Laundering Regulations, isn’t just for banks—it also covers cryptocurrency companies, making sure they play by the same rules as traditional financial firms. Every business in the system must check who their customers are and keep records for five years. They also have to watch for suspicious activity and train staff to spot risks. Crypto firms got added to the mix in 2020, and since 2023, they’ve had to follow new traceability rules for digital transfers, similar to how banks track wire payments. If something looks off, they must report it—failure to do so can lead to big fines or even criminal charges.What’s interesting is how these rules keep changing. The government tweaks them every few years to plug loopholes, especially in crypto. For example, in 2026, stricter checks for risky crypto payments will kick in, and by 2027, even more controls will roll out. Businesses have to stay on their toes because the rules depend on when they operate and what services they offer.
