In the process of purchasing a timber garage which will be used exclusively
as a workshop. I am trying to do as much as possible on my own and have just
finished compacting the hardcore prior to concrete pouring (yet to be
arranged).

Off the top of my head (and thus in no particular order):

Place the workbench along the major axis of the building so that you can deal
with long lengths of (say) wood in any bench vice.

Twenty quid was the cost of a 700mm by 2400mm sheet of twinwall polycarbonate
that I bought a month or so ago to install in the flat roof above my own
workbench - you can't beat natural light.

The consumer unit will cover lights and sockets but some day you might want
to put (god forbid :-) a freezer in the building thus an RCD protected supply
might not be the best for such an appliance. So a small four-way consumer unit
might be better.

Run extra cables and/or a length of string in cheap 40mm drain piping along
with your mains supply cable to the workshop. Wrap the drain piping in some
stripey tape to warn the next punter whats in the pipe.

The extra cabling for alarm, intercom, wired network access, wired phone
extension, etc etc.

Use four-core for the mains feed - this allows switching of a separate line
from the house - you may want to switch a shed-mounted light from the house,
or you may want to switch off a shed-mounted PIR security light on a windy
night when the light switches on and off regularly.

Rainwater barrel to collect the runoff from the roof?

P.S. Silly question, but do you plan to bolt the shed to the concrete base?
If you dont, you run the risk of losing the shed when damaging storm winds
blow.
Add some anchor points before you pour the concrete?

Will you be using some sort of polythene membrane over the hardcore before
pouring the concrete?

Keep the hardcore about 50mm short of the shuttering boards so that the
concrete goes down the full face of the shuttering boards and thus it forms
a complete cap over the hardcore (when you remove the shuttering boards
you shouldn't be able to see hardcore at all).
