Practical AI governance designed for accounting firms.
AIGAS is the first governance standard built specifically for UK accountants — helping you evidence how AI is used in your firm, without the weight of enterprise standards.
AI is already in your firm. Governance isn’t.
It’s not future AI that’s the risk — it’s the AI already embedded in Xero, QuickBooks, Copilot and ChatGPT. AIGAS gives you a way to catch up.
You don’t know where AI is used
Embedded features, staff experimenting with ChatGPT, informal automations — most firms have no reliable inventory of what’s actually running.
You can’t evidence oversight
If a regulator, insurer, or client asks how you govern AI use — most firms can’t produce a defensible answer today. AIGAS closes that gap.
Big standards feel out of reach
ISO 42001 is coming — but for most small and mid-sized firms it’s too heavy right now. AIGAS is the practical bridge to get you there.
A governance standard shaped by how firms actually work.
AIGAS — the AI Governance Assurance Standard — is a practical framework created for UK accounting firms. Not a theory document. A working standard, with a platform, a pathway, and an independent advisory board behind it.
