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:

More than a one-off check. Certaby brings the parties, the property and the right checks into one transaction, keeps the signed evidence, monitors the parties for changes, and holds the written AML policies and records to show when HMRC asks. Built for the May 2025 sanctions rule that now applies to every UK let and sale.
For a let
Tenant + landlord + property in one signed PDF. OpenSanctions PEP + adverse-media, PSC walks for corporate landlords, MEES, crime + flood.
See the letting-agent suiteFor a sale
Buyer + seller AML + the environmental risk pack in one signed PDF, alongside your regulated searches.
See the conveyancer's packWhy 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 pricingThe checks
A transaction runs the checks each let or sale needs and keeps the signed evidence together. You can also run any one of these on its own when that is all you need.
Score a UK company A to F across eight risk factors: insolvency, charges, overdue accounts, officer churn and more.
From £2.95 per check
Pull a UK company's profile, current officers and filing status from Companies House.
From 49p per check
Look up the Energy Performance Certificate for any UK property by postcode or LMK key.
From 49p per check
Confirm a firm's authorisation status, permissions and key individuals on the FCA register.
From 99p per check

From 99p per check
Screen a name against OFSI, UN and EU consolidated sanctions plus the OpenSanctions PEP and adverse-media catalogues.
From 99p per check
Open 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.
Mix and match
Not a profession-aligned suite (those are at the top of the page) and not a single check either. Use a pack when you specifically need 2 or 3 individual checks together at a better price than running them separately.
