Welcome bensyboy to the site, like admin says my advice would be to marry in the phill, which should be easier for you to organise than most of us as your brother allready lives there.
The wedding will cost less, your wife to be family can all go (almost impossible if held in europe due to visa and cost issues).
Also once your wife is in the Uk you should have less paperwork to bother with, than if you then have to arrange visa paperwork and the Wedding.
Your Wife needs your full attention as it is much tougher for most phills to adapt to UK life than it is for Europeans to adapt to life in Phil imo.
I wish you all the best for the future and hope you stay with the site as this site is a mine of infomation.
