    Hey guys so to clear this up abit for myself to help me understand

    When you talk about a CT and meter, is this a CT with required ratio and analog meter on DB board door(these are the only 1's I am familiar with on the incoming section of automation systems) or are these like the intelligent meters you speak about more sophisticated with recording etc... (ie elster a1700 & landis & gyr)

    I don't think an analogue meter system is going to give you the reporting you need. You definitely need a digital meter with appropriate current transformers. The digital meters also give you data logging as well as onboard storage. You can dump the on-board memory onto a laptop or tablet via an optical coupler which is USB. Some of the metering devices are ip addressable so you can also remote query them via a GSM setup or even CAT5 cable them and hang them off a switch or router but honestly this is over complicated for what you need. Software is often but not always supplied free but it's worth checking before you run out and buy one. The software gives you basic data manipulation facilities as well as graphing and it's often integratable with Excel which can be handy.

    You can also check out the Zaptronics range of metering, the agents are Electromechanica. I have used several of their models and haven't had problems.

    AndyD & murdock, thanks guys for all the useful info. Let me consider and see whats the best option as budget is tight at the moment. But I guess the money saved could pay for the meter in the long run...
