Why ISO 42001 Matters for Accountants
You're already using AI—probably without realizing it. Here's where AI is hiding in your practice:
📊
Xero AI Features
Invoice extraction, bank reconciliation suggestions, expense categorization, cashflow forecasting
🧮
Sage AI Features
Smart capture, predictive cashflow, automated invoice chasing, VAT return suggestions
💼
Practice Management
Client risk scoring, workflow automation, document classification, time predictions
The Problem: Most accounting firms can't answer:
- What accuracy threshold triggers human review?
- How often is the AI model audited?
- Is client data used to train vendor AI?
- Who's liable when AI makes a mistake?
ISO 42001 Solves This: Document your AI usage, demonstrate responsible governance, win clients who ask hard questions.

Frequently Asked Questions
Do you offer payment plans?
Yes, for programmes over £5,000, we offer payment plans: 50% deposit, 50% on completion. For ISO 27001/42001 (6-12 month programmes), we offer monthly payment options. Contact us to discuss.
What if we're not ready for certification yet?
That's fine. Most firms start with a readiness assessment to understand their gaps and create a roadmap. You can implement at your own pace and certify when you're ready. We support both approaches.
Do you work with accounting firms outside Hampshire?
Absolutely. While we're based in Fleet, Hampshire, we serve accounting firms across the UK. Most of our work can be done remotely, with on-site visits for critical milestones (gap analysis, audits, training). We've successfully supported firms from London to Edinburgh.
What's included in the "founding member" ISO 42001 offer?
The first 5 accounting firms to commit to ISO 42001 Readiness or Full Implementation get 50% off (£7,497 or £14,997 instead of £14,995 or £29,995). You'll also co-create a case study with us (subject to your approval), receive lifetime advisory support on AI governance, and be positioned as an industry leader.
How long does Cyber Essentials certification actually take?
From start to certification: 4-6 weeks for Basic tier (you do most work), 4-6 weeks for Professional tier (we do 50% of work), 6-8 weeks for Enterprise tier (complex environments). Timeline depends on your current security posture and responsiveness.
Can we bundle multiple services together?
Yes! Many firms bundle Cyber Essentials + ISO 27001, or start with CE and upgrade to ISO 27001 within 12 months. We offer discounts for bundled services. Contact us for a custom quote.
What makes you different from other consultancies?
Three things: (1) We specialize in accounting firms—we understand your software, your workflows, your clients. (2) We're one of the UK's first ISO 42001 consultancies—you get first-mover advantage. (3) We're local, personal, and jargon-free—no call centers, no corporate BS.
