Where should I setup a bank account in Isle of Arran?

"Expats considering retirement in the Isle of Arran, should be aware that the cost of living can be higher than in other parts of the UK due to the island's remote location. They should also know that the weather can be quite changeable, with mild winters and cool summers, and that it can be quite windy. The island has a small population, so it offers a close-knit community feel, but it may lack some amenities and services found in larger cities. Healthcare services are available on the island, but for more specialized treatments, one may need to travel to the mainland. The Isle of Arran is known for its natural beauty, with plenty of opportunities for outdoor activities such as hiking, golfing, and wildlife watching. It's also home to several historical sites and a renowned whisky distillery. Public transportation is available, but services are limited, so having a car can be beneficial. The island is accessible by ferry from the mainland, and there's also a small airport. Expats should also be aware that they will need to comply with UK immigration rules, which may include obtaining a visa. It's also important to understand the tax implications of retiring in Scotland, as the country has its own tax rates and bands separate from the rest of the UK. Finally, while English is the primary language spoken, the island has a strong Scottish heritage and culture, and some residents speak Scots Gaelic," said another expat in Isle of Arran, Scotland.
