Charities supported by the Royal Family are being reviewed following King Charles's Accession.
The Royal Household is looking into hundreds of Royal Patronages and Presidencies, previously held by the late Queen Elizabeth II.
Aides are also reviewing organisations, supported by The King and Queen Consort when they were Prince of Wales and Duchess of Cornwall.
The Royal Family "tend to limit their patronages to a manageable number" to ensure that they can give each organisation more of their time, according to the Royal Family website.
It is understood no decisions are expected before the Coronation.

Royal Patronages usually add "status" to an organisation and can often bring "much-needed" publicity through visits and collaboration with the working royal.
The Royal Family website states: "Following His Majesty The King's Accession, the Royal Household is conducting a review of Royal Patronage.
"The review will cover the organisations of which Her Majesty Queen Elizabeth II was Patron and those organisations to which The King and The Queen Consort were connected through Patronage or Presidency as Prince of Wales and Duchess of Cornwall."
The late Queen was the Royal Patron or President of more than 500 charities, some of which were inherited from previous monarchs.
Patronages or Presidencies can also be handed down to younger generations.
Prince William became the third generation of the Royal Family to become President of the British Sub-Aqua Club in 2014, following on from his father (then Prince Charles) and grandfather (Prince Philip).
Patronages and Presidencies tend to reflect the personal interests and passions of the Royal Family.
The Queen Consort, for example, is President of the Royal Osteoporosis Society because both her mother and grandmother died whilst battling brittle bone disease.
Last month, Her Majesty toured the new city centre offices of the Royal Osteoporosis Society in Bath, and it is thought unlikely The Queen Consort would cease to be President of the organisation following the Royal Household's review.

Her Majesty launched the successful Instagram "Reading Room" in 2021 which now has more than 155,000 followers.
The King's patronages as Prince of Wales stemmed from his interests in sustainability and the arts.
It is understood His Majesty's workload has significantly increased since becoming King and often works early in the morning and late at night.
The King and Queen Consort will be crowned in Westminster Abbey during their Coronation ceremony on Saturday 6th May.
Buckingham Palace has been approached for comment.
