British citizens / UK nationals now have to follow the same process as other non-EU national citizens of third countries to get Spanish residency, i.e. there is a requirement to first obtain a visa.
The financial means required for a British Citizen / UK national to obtain a residency visa, is a lot higher than it was when the UK was in the EU. A single applicant needs to have around €30k per year in either income or savings, whereas a citizen of an EU country €6k is sufficient.
British nationals also have to obtain a police criminal report, get official supporting documents legalised, and medical certificates are also required for most visa applications.
Nationals of non-EU countries require a visa to enter Spain, if the stay is intended to be more than 90 days. The Schengen visa in most cases cannot be used to apply for residency in Spain.
There is an exception when an immediate family member is joining a family member who already lives in Spain and holds Spanish residency. In all other circumstances a citizen of a non-EU country must apply for, and obtain a long stay visa through the Spanish Embassy in their home country.
Since UK has now left the EU, UK citizens / British nationals also have to apply for a visa if they want to live or work in Spain.
Once the visa has been issued, the applicant can travel to Spain and apply for residency and get their TIE, ‘tarjeta de identidad de extranjero‘.
The following is a summary of the main types of long stay visas that citizens of non-EU countries can apply for.
