No, that is no longer possible. Due to Brexit, the UK has ceased to be a member of the EU, and the transitional period ended on 1 January 2021. Banks from outside the EU are prohibited from holding deposits from customers residing in the Netherlands. There are a few exceptions, however: see the fact sheet. If you still have an account with a UK-based financial service provider, please discuss the options with them. Sometimes a UK bank can transfer your account to a new or existing branch in the EU.
