Switzerland was second on the list. The European country has many expat residents, especially in cities such as Geneva, Zurich and Bern.
While the country has incredible natural scenery, very low pollution levels and a low crime rate, expats will pay a hefty price to live there.
According to Expatistan, the average monthly costs for a single person in Switzerland are CHF 3,718 (£3,321).
Although salaries are generally high in Switzerland, retired British expats might struggle to cover the expensive prices.
