When you have finished checking you are still insured on all your policies, ie mortgage and life if you go, have a chat with the nice people at the Tax Office. If memory serves, you are only allowed 90 days pa in the UK for tax free earnings.
If my memory is correct, if you do one year out there now, you will be taxed in the UK.
Best of luck to you, me I would put an extra quid a week on the Lottery, much safer and far more civalised.
