Common questions about how to build a proptech platform in the uk — land registry, aml & rics (2025).
Yes — software platforms used by estate agents must support AML obligations. Estate agents are HMRC-supervised for AML under the Money Laundering Regulations 2017. This means: CDD for buyers/sellers in transactions above £10,000, EDD for high-value or high-risk transactions, suspicious activity reporting capability, and 5-year record retention. HMRC audits estate agents and expects their technology to support these requirements.
HMLR Open Data (Price Paid Dataset, INSPIRE Index Polygons): free, no agreement, open government licence. HMLR Developer Portal: free registration, Search for Land and Property API. Official Copy API: requires HMLR business account. Rightmove/Zoopla listing data: commercial agreements required — significant cost for high-volume access.
