Data Centres
Technical environments where access, cleanliness and record keeping are tightly controlled. We work to agreed permits and change windows, with attendance and task sign-off documented at the point of work. Scope and delivery arrangements are confirmed following a site review.

Access under permit
Escorting, inductions and permit requirements agreed in writing before any attendance.
Technical cleaning regimes
Cleaning methods and frequencies set by area type, from white space to plant and loading areas.
Planned change windows
Disruptive tasks scheduled into agreed windows and evidenced afterwards.

Nothing happens without a permit
Inductions, escorting and permit requirements are agreed in writing before anyone attends, and the same rules apply to every member of our supply chain.
Cleaning by area type
Methods and frequencies are set separately for white space, plant rooms, loading areas and support space, because the risk and the acceptable materials are different in each.
Disruptive work in agreed windows
Anything that could affect the operating environment is scheduled into an agreed change window and evidenced afterwards. Scope and delivery arrangements are confirmed following a site review.
- Permits and induction records
- Attendance logged against each visit
- Cleaning sign-off by area type
- Change window completion evidence
