Again, all national averages (ignore rural/urban etc) over the last 12 months

Specify which 12 month period, but give option of defining own if the one given is unsuitable/unable to collect data for it.

Procurement and installation of switches includes costs/manhours associated with the purchasing procedure of the switch, including the switch cost and installation and supervision (if the work is contracted out).

Labour costs and man hours should be direct labour costs and man hours, including those associated with supervision and direct clerical support, but should not include allocated overhead such as management and R&D.
