that is not nearly enough things are not just a little more expensive than the UK they are ALOT more expensive. My running joke is that they only 3 things cheaper than UK here are:

petrol
batteries
ciggies

everything else from rent to food to dining out to vets bills to clothes are considerably more than the UK. You should be looking at min salary 25k/month plus 12k housing allowance and 2k car allowance plus flights, plus end of service benefits (this is the law) plus medical. Anything else, don't leave the Uk, you would resent giving up living in the UK to move somewhere where you could not even save any money or you lived a very bad existence in order to save the money.
