Is this business supervised by HMRC under the Money Laundering Regulations, for what, and has that changed.

Registered or not, sectors, status, since when, postcode district against the registered office, former registrations and when they went; plus a feed of every change on the register since a date.

Estate and letting agents, accountancy service providers, trust and company service providers, high value dealers, art market participants and money service businesses must be registered with HMRC under the Money Laundering Regulations before they trade, unless another body supervises them. HMRC publishes the register as one spreadsheet, refreshed roughly weekly, with no company numbers and no dates of change. We keep every file and record the differences, so this endpoint says whether a business is registered, for which sectors, with what status (Approved, Applied, Expired) and since when, with the postcode district checked against the registered office; and the changes feed lists every business added, removed, returned or re-statused since a date. HMRC supervises some sectors only, so a business not on its register may be supervised by the FCA, ICAEW, ACCA or another body: the reply says so rather than guessing. Registrations under a person's own name aren't loaded.

Why developers pick it

The history nobody else keeps

HMRC's file has no dates of change; only someone keeping every file can say when a registration lapsed. We do, since 7 October 2026.

Matched to the company

A company number brings its registered and former names, and the postcode district is checked against the registered office.

Honest about scope

HMRC is one supervisor among several: a business not on its register is never called unsupervised.
