For 2026, Portugal and Greece remain the top contenders for retiring with a UK pension due to their favorable tax regimes and low cost of living. Portugal’s "D7 Visa" is a popular path for those with passive income, offering a high quality of life and a large expat community. Greece is also highly attractive, offering a flat 7% tax rate on foreign pension income for new residents who spend more than 183 days there. For those looking outside Europe, Thailand offers specialized retirement visas (O-A and O-X) and world-class private healthcare that is far more affordable than in the UK. Spain remains a perennial favorite for its proximity to home and excellent climate, though its wealth tax can be a hurdle for some. When choosing, it’s vital to consider the "Triple S": Sunlight, Social healthcare access, and the Stability of the local currency against the Pound, especially in the post-Brexit landscape where visa requirements have become more formalized for UK citizens.
