Pricing and timeline in context
Based in London, UK, Deloitte quotes SOC 2 work in the $75K–$400K band — in line with the big four median of $75K–$400K across the firms we track. As an AICPA-licensed CPA firm it issues SOC 1, SOC 2 Type 1, SOC 2 Type 2, and ISO 27001 reports directly, and the fee scales with your headcount, the Trust Services Criteria in scope, and any frameworks you bundle. Plan for roughly 16–36 weeks on a Type 2 engagement. Compare it against the full SOC 2 audit cost benchmark before you commit.
Who Deloitte is for
Deloitte works most often with SaaS, Fintech, Healthcare, AI / ML, E-commerce, and GovTech companies, serving clients across United States, United Kingdom, Canada, European Union, Australia, and Global. Enterprises and regulated organizations that need a globally recognized name on the report are the natural fit — expect a fee premium for that brand.
