I've gone for the commando/OHME combination too and had it installed last Monday but haven't used it (apart from testing) as the Agile prices have been so high. The commando socket was from Gewiss, can't remember the details ATM but was IP76? and installation was free - Christmas present from a friend!
My electric/gas DD is £20 a month although that may have to change as I start to charge the car more at home and I'm currently £40 in debt which should change over the spring and summer as I have 4kwp of solar panels. Your usage does seem high to me at any rate!
