UK pension is linked to cost of living/inflation etc. The pension paid goes up to reflect this in the UK, Europe, USA for example. It never goes up if you live in Thailand. But an advantage of spending some time in the Philippines is that you receive the increases for the time you are there.
Thanks for the response. I've been to Cambodia, it was chilled out, and yes the population is young... personally it doesn't draw me so much, although Siem Reap was ok. Are you in the same position tax wise there, ie 180+ classed as resident and pay tax on foreign income? Thanks.
