The average UK office worker loses 12–18 hours per week to manual admin: data entry, status chases, formatting, switching between systems, and reporting. That's £14,000–£22,000 per employee per year of pure overhead.

Studies and our own client audits agree: 12–18 hours per worker per week vanish into manual admin. The breakdown is consistent:
At a UK fully-loaded rate of £35/hr, 15 hrs/wk × 50 wks = £26,250 per employee per year of pure admin overhead. For a 10-person team, that's £262,500/yr.
AI workforce automation removes 60–80% of this in months, not years.
No. Anyone who has actually measured (timesheets, calendar audits) finds the same range. People underestimate admin time by ~40%.
That's exactly the problem. Admin is invisible because it's distributed across the day. The calculator surfaces it as one number.
