My annual budget is about £23k + £24k for licences (not just mine but whole school ones like SIMS, Cashless catering etc). Out of my normal £23k i have to buy all toner for all my 30 printers as well as everything else. I try and leave most of my budget alone until the end of the year then have a nice little chunk to try and do something with (hoping to have saved 1/3 this year!).
I have been very lucky over the last 2-3 years with serious investment being made in the network here from central pots of money, ive had a whole new network (servers, san, switches, ups), as well as replacing all machines in 3 out of 4 of our it suites and replacing all classroom machines to run the whiteboards. In my defense the whole network was 6/7 years old and the switches even older still, some of our whiteboard machines were at least 8 years old as well!
