Close family relative has asked if they can temporarily use my address for their new bank account as they’ve just returned from living abroad, need to open a UK bank a/c and don’t want banking info being sent to the rented address they’ll be living in as others will be living there that they don’t know. Any potential problems with this? I’m not claiming welfare benefits but do claim the 25% council tax deduction as I live here alone. They won’t be living at my address but 100 miles away.
