Conveyancer's Compliance + Property Pack

Buyer + seller (sanctions / PEP / adverse-media / FCA Warning) + property + environmental, in one signed pack PDF.

What it does

The Conveyancer's Compliance + Property Pack composes the S1-reused sanctions + PEP + adverse-media + PSC + audit-grade-PDF capabilities with the S2-specific environmental risk pack: long-term flood (Risk of Flooding from Rivers & Sea + Surface Water + historical events from EA Recorded Flood Outlines), radon (UKHSA Radon Atlas), coal mining (Coal Authority DHRA point-in-polygon), contaminated land + landfill register (per-LA adapter pattern + EA national register), Japanese knotweed (INNS / iRecord proxies), plus C-FCA-3 FCA Warning List. One POST returns combined JSON plus a signed Conveyancer's Pack PDF URL ready for the file. It pre-screens the parties for AML and triages the property's environmental risk in one deliverable, alongside (not replacing) the conveyancer's regulated, insured searches.

Built for

  • UK conveyancing firms running MLR-2017 + Law Society client due-diligence
  • Solicitors who want one PDF per matter in the client file
  • Lender panels that need both ID + environmental risk pre-exchange

Reliability you can build on

Built on the same AWS infrastructure that runs UK banks and government services. Engineered for the kind of always-on availability your compliance workflow expects.

Target 99.9% uptime

Stack uptime is governed by AWS API Gateway (99.95%), Lambda (99.95%) and DynamoDB (99.99%) SLAs. We target 99.9% end-to-end, which works out at roughly 8 hours of downtime per year, worst case.

Hosted in London (eu-west-2)

Single-region UK hosting for low latency to UK customers and predictable data residency. Median response under 250ms; 5-minute response cache absorbs upstream blips.

Idempotent + cached

Repeat lookups within 5 minutes are served from cache, so transient FCA upstream issues don't propagate to you. Bulk endpoint runs with bounded concurrency to never overrun the source.

Contractual SLA on Pro

Pro plan includes a 99.9% uptime commitment, priority support with response in under 4 hours (UK business hours), and a private Slack channel for incident escalation.

Live status visibility lands with the public dashboard. Full incident history available to Pro customers on request.

Pricing

Billed per check (one transaction = one signed PDF). No monthly subscription; volume packs bring the per-check rate down.

Why this pricing?

Ladder B (2026-05-21; see docs/conveyancer-pricing-analysis-2026-05-21.md). Full pack £29.95: buyer + seller AML + PSC + the environmental risk pack + signed cert. It pre-screens the parties and triages property risk; it does NOT replace an insured, lender/CQS-accepted CON29-grade search, so it is priced as a credible undercut on combined AML + compliance cost, not a 1:1 search substitute. Standalone tiers: £4.95 buyer-only (single-party screen), £7.95 environmental-only (non-insured risk triage). Pro £49.95 adds the priority + SLA + named-contact service tier.
