In February 2025, HMP Wormwood Scrubs modernised its outdated Flexitime processes with the implementation of HFX Imperago. Led internally by Devon Finnis, (People Hub Manager), the project has delivered measurable efficiency gains, stronger compliance and a significant reduction in administrative workload.
The Challenge
Before implementing HFX Imperago, Wormwood Scrubs relied on:
An outdated Flexitime system requiring printed balance reports
Manual clock cards for attendance
Paper-based flexi sheets
Limited visibility for managers
Annual leave processes open to error and manipulation
Inconsistent alignment with HMPPS policy
The result?
High administrative burden
Excessive paperwork
Limited visibility
Compliance risks
Inaccurate leave balances
The system was no longer fit for purpose in a modern custodial environment.
The Solution
HFX Imperago replaced manual processes with a secure, digital Flexitime and attendance management system, providing:
Secure login-based clocking (eliminating physical clock cards)
Automated flexi balance calculations
Accurate annual leave recording
24/7 real-time reporting
Visual absence management dashboards
Integration capability with the SOP sickness system
"Implementation was smooth and fully supported. The implementation team were great and got back to me fast to answer any questions.”
Devon Finnis, (People Hub Manager)

"Really good visually for absence management. The support is really quick. Tickets have typically been resolved on the same day.”

Cultural Change with Lasting Results
While there was some early resistance — particularly from longer-serving staff used to manual systems — feedback following implementation has been overwhelmingly positive.
Staff particularly value:
No longer completing manual flexi sheets
Clear visibility of balances
Faster processing of requests
Greater fairness and consistency
The shift to digital has simplified processes across the prison.
