In answer to your question if the meter readings are correct
then its likely you are being charged correctly, but...
just checking you are reading the actual meter and that's kWh for electric?
You aren't reading kwh for gas are you?
and as jon1's reply, if that's electric 12500 in 5.5 months call it 23 weeks about 550 units a week, or over £70 a week!!
No wonder you're £600 in arrears
100kWh would be generous and for one person and 60 to 70 (unless you take long electric showers) would be nearer as a guess.
So...something is wrong, is the meter actually in your flat and wired only to your flat or could it be measuring for someone else?
If you had an immersion I doubt reach those figures unless you were running off very hot water for a long time.
There aren't any halogen security lights on constantly are there?
Turn everything off at the fuse board (consumer unit) and see if the meter is still reading..
If not then one breaker at a time and see what happens.
It's always possible that the meter is broken, but you need to do some tests at your end before assuming that or you'll get charged if they test it and it's OK
If the meter is registering correctly you need to figure out where the energy is being used.
