For UK letting agents and conveyancers · live · 2026 update
For UK letting agents and conveyancers. Run the sanctions, PEP, ownership and property-risk checks each let or sale needs, keep the signed evidence with a 7-year verify link, monitor the parties for changes, and hold the written AML policies and records an HMRC inspection asks for. One place, pay per check.
Since the May 2025 sanctions rule, every UK letting agent must screen the tenant and landlord on every let, and conveyancers carry the same duty on a sale. HMRC is penalising firms that cannot show the audit trail.
Start free, then handle your first let or sale:
For a let
Tenant + landlord, plus the property.
+ property-risk pack: flood, radon, coal, contaminated land, knotweed
One signed PDF, audit-grade, 7-year verify URL.
For a sale

+ property-risk pack: flood, radon, coal, contaminated land, knotweed

Why Certaby
Flood, MEES, radon, coal mining, contaminated land, and knotweed alongside the AML check, in one signed PDF. Across the 22 vendors we compared, the only one we found that overlays property risk on the compliance flow.
See what the suite checksEvery check ships a signed PDF with a /verify URL that resolves for 7 years, even if you cancel. Most tools lock your certificates behind an active subscription, so cancelling loses your audit trail.
How verification worksPay per check with no annual minimum, no seat licences and no sales call. Transparent sources named on the cert (OpenSanctions for sanctions and PEP), not a proprietary black box.
See pricingOpen the hub and start a let or a sale. Add the parties and the property, and Certaby shows exactly which checks the regulations ask for.
See the price upfront and run the checks you need. Right to Rent is free, and one signed certificate for the whole transaction is included.
Results land in seconds with a hash-verified certificate and a 7-year verify link. Add monitoring or the AML documents when you need them.
