Do the commonwealth detachment. You will get the right to live in a part of the world which is comfortable. Better the devil you know. The civil world for new joiners is not good. Your experience will not be valued. You will be viewed exactly as a pay to fly kid who is wet behind the ears. You will have NO input.
I cannot emphasise do not join the civil aviation world in the UK.
easyjet etc are **** I cannot tell you how bad but if you want to retain any self respect do not join the civil market...
