Why use Certaby instead of a spreadsheet + manual checks?

A manual workflow for one letting-agent client check looks like: open OFSI consolidated list, paste the tenant name; open OpenSanctions, paste again to get PEP and adverse-media; open Companies House for the corporate landlord, walk the PSC tree by hand; open MHCLG EPC register for the property, look up the band; open the EA flood map, check the postcode; open Police.uk, check the area. That is six tabs, three free-text searches, and around 30-45 minutes of officer time per let. The output is a folder of screenshots and a row in a spreadsheet that nobody can hash-verify after the fact.

Certaby's letting-agent suite runs the same eight checks (sanctions + PEP + adverse media + UBO walk + MEES + crime + flood + monitoring) in one transaction at £4.95. The output is one signed PDF for the client file, with a SHA-256 hash printed in the footer plus a public verifier URL the regulator can hit from the cert alone to confirm the cert has not been edited.

What that buys the firm:

1. Time. 30-45 minutes per let down to under a minute.

2. Audit defensibility. The hash + verifier means a regulator inspection in 6 years cannot say 'someone could have edited this'.

3. Cross-source coverage. Manual workflow misses the OpenSanctions PEP catalogue most of the time; LSAG-2025 expects it.

4. Property-risk overlay. Spreadsheet workflow rarely includes flood, MEES, or crime; the firms that ship those have a depth advantage.

For the firms doing it manually today, the £4.95 per let is comfortably below the loaded officer time it replaces.
