Hello Lee,
The average is 125 beds/tech, but it is very much dependant on how much is spent on service contracts. The more service contracts there are, the less need for techs, so the ratio's vary from 80 beds / tech to 200 beds / tech. (in my experience)

The average spend on medical devices maintenance is usually 0.9% to 1.3% of Gross. i.e. if Trust Gross is £100M the spend will ususally be around £0.9 to £1.3M.
So far as non-pay budget, do you mean equipment replacement budget?
Again, as a rule of thumb, the average Trust will have an asset value (For medical equipment) of around 7 to 12% of gross. So for a 500 bed Hospital with a £100M budget, you should be looking at £7M to £12M. To keep this turning over every 7 years, you can do the maths, but an annual investment of £1M would be realistic.
