This is what we found on Wikipedia regarding the Kensington Palace:

Kensington Palace is a royal residence set in Kensington Gardens, in the Royal Borough of Kensington and Chelsea in London, England. It has been a residence of the British royal family since the 17th century, and is currently the official London residence of the Prince and Princess of Wales, the Duke and Duchess of Gloucester, the Duke and Duchess of Kent, Prince and Princess Michael of Kent and Princess Eugenie and her husband Jack Brooksbank and their two sons. Kensington Palace is sometimes used as a metonym for the offices of royals who officially reside there.

Today, the State Rooms are open to the public and managed by the independent charity Historic Royal Palaces, a nonprofit organisation that does not receive public funds. The offices and private accommodation areas of the palace remain the responsibility of the Royal Household and are maintained by the Royal Household Property Section. The palace also displays many paintings and other objects from the Royal Collection.
