An easy way to tell whether a property is commercial or residential is to work out what the building is currently being used for. Typically, properties used for business purposes, such as restaurants, banks, offices or shops, are classified as commercial properties. Residential properties, on the other hand, include houses and flats where people live. For more detailed information on a specific property, you can search for property details and purchase specific documents relating to a property on the Government Land Registry website here.
