Neophyte

Hi, I am new to the board and as a first time buy to let landlord. My wife and I really strong about keeping our details private. We are therefore going to use PO boxes and letting agents to create as much privacy as possible and protect our details. However, one area of concern is that we still need to list our name to the letting agent. We have no plans to be dishonest and will make sure the house is in a good state and any future issues with the house that we will be contactable through the agent. We have a unique surname and the property we bought is in very near vicinity which is why we wish to our names not to be shared publicly. Is there any advice if there are ways to protect our privacy as it is a small area we live in. Is it legal to use an alias on the tenancy agreement e.g. wife's maiden name or is this against the law to use an alias?
