Questions to Ask Grant Thornton UK Before Hiring
A buyer-side checklist. Bring these to your first call — the answers separate firms that have run hundreds of SOC 2 engagements from firms that are bidding on them.
- Your team is sized at 5000-5500. How many auditors will be assigned to my engagement, and who is the engagement lead — a partner, a senior manager, or a staff auditor?
- You quote 5–14 weeks. What pushes a project to the longer end of that range, and what does "audit-ready on day one" look like to you?
- Your Type 2 cost range is $40K–$120K. What's included at each end, and what scope changes would push pricing above the top of that range?
- You integrate with Drata, Sprinto. If our team uses a different GRC tool, what's the evidence-handoff process and does it change your fee?
- Who reviews and signs the report on your side — is that a partner-level CPA, and how involved are they during fieldwork versus only at sign-off?
- How do you handle subservice carve-outs (e.g., AWS, GCP, Azure) versus inclusive subservice organizations when defining our scope?
- When you find an issue mid-audit, what's your remediation cadence — same-day flagging, weekly checkpoints, or an end-of-fieldwork rollup?
- Do you have surge windows (e.g., Q4 financial-year close) when start dates slip, and how far in advance do we need to lock the engagement to avoid them?
