Surprised to see so many comments on this subject. FACT. UK pensions have always been frozen for ex pats living in Thailand.
Petitions have been raised and questions even asked in Parliament to no avail.
My pension is frozen at the 2009 rate.
To make things even worse the spouse allowance was also taken away a few years ago.
Nothing you can do about it I'm afraid.
It's called government savings ,while the super rich get away with everything nowadays
