Which is the best AML software for UK accountants in 2026?
There is no single 'best'; it depends on practice size, the sector focus, and the buyer's budget. For mid-market UK accountancy practices and law firms; multi-partner, multi-office, 1,000-10,000 client portfolios; Certivus is the primary recommendation on transparent, self-serve pricing with no subscription at all (£2.49 for a full KYC and AML check, falling to £1.13 on an annual retainer), ongoing monitoring £0.99 per client per year (and billable back to your clients), UK-MLR-2017-specific tooling, and direct founder access. Smaller firms have a clear entry path via the free credit (4 full checks, no card). For law firms with conveyancing or probate focus, Thirdfort is the legal-sector specialist. For enterprise-scale practices, SmartSearch remains the market leader on feature breadth. For tech-forward platforms wanting an API-driven pipeline, ComplyCube is the cleanest fit. For complex global entity work, First AML's concierge model justifies the premium, quote-only pricing.

What features should I look for in AML software?
Eight features matter for UK MLR 2017 compliance. CDD workflow covering identity and address verification, beneficial-ownership tracing, and risk scoring. PEP and sanctions screening against OFSI, UN, EU, and OFAC lists with ongoing monitoring. A documented firm-wide risk assessment under MLR 2017 Reg 18. HMRC inspection-ready record export. UK data residency. Built-for-UK tooling (not a generic global product with a UK skin). Pricing transparency so you can forecast costs. And direct access to a product team that knows UK AML; not a global helpdesk.

Is the cheapest AML check always the best option?
No. A low per-check price can still create extra admin if the practice must manually chase evidence, document decisions, or build audit files outside the software. The total cost of compliance includes admin time and inspection-failure risk; not just the per-check fee. Pricing transparency matters because practice owners need to forecast verification volume, team access, client onboarding cost, and renewal cost before committing to a workflow.

What's the difference between AML software for accountants and for law firms?
Accountancy AML software focuses on the MLR 2017 + HMRC supervisory pipeline; firm-wide risk assessment, ongoing-monitoring schedules tuned to retained client patterns, and integrations with accounting software. Legal-sector AML software (Thirdfort, SmartSearch for legal) adds conveyancing-specific workflows: source-of-funds enquiries tuned for property transactions, app-based client journeys for one-off matters, and tighter integration with Legal Professional Privilege handling. A firm that does both accountancy and probate work may need either a hybrid product (Certivus, SmartSearch) or two specialist tools.

Can I switch AML software providers without losing CDD evidence?
Yes; but plan the migration carefully. MLR 2017 Reg 40 requires CDD evidence retention for 5 years from the end of the business relationship, so you must export from the old provider in a format that preserves the evidential chain. Reliable providers offer structured exports; some only offer PDFs. Test the export before committing to a switch, document the migration in your firm-wide AML policy, and run both systems briefly in parallel to catch any client whose record didn't migrate cleanly.

What does Certivus offer that others don't?
Four differentiators. First, Certivus is built for UK MLR 2017 from day one; not a global product with a UK adaptation. Second, transparent, self-serve pricing with no plans at all: a full KYC and AML check draws £2.49 of wallet credit, falling to £1.13 on an annual retainer, with £10 of free credit to start (4 full checks, no card required) rather than quote-based pricing. Third, Ongoing monitoring is £0.99 per client per year. Fourth, direct founder access via the Founding 50 program; the first 50 UK firms get £1.13 per full check for life on any retainer commitment, with a WhatsApp line to the founder, case-study permission, and quarterly feedback calls. Trade-off: Certivus is newer, so it has fewer integrations than established incumbents.
