Charles III looks set to face a king-sized council tax rise when new charges for second home owners are introduced.

For the monarch's bill for Sandringham House in Norfolk is set to increase by more than £4,000 when new rules come into force next April.

More than 3,000 owners of second properties in west Norfolk are set to receive letters later this month setting how much extra they will be asked to pay, after the council agreed to a 100pc surcharge earlier this year.

It comes after widespread concerns were raised over the impact of second homes on communities such as those on the Norfolk coast, where burgeoning numbers of holiday properties are pushing house prices out of the reach of locals. 

Band H properties in Sandringham currently pay £4,272.76 a year, meaning the monarch faces paying an extra £4,272,76 in council tax.

A spokesman for West Norfolk Council, which is the local authority covering both properties, said: "In West Norfolk, we are proud of our enduring links with the Royal Family. 

"Sandringham is well-known as a Royal residence, however we cannot divulge the personal tax payments or arrangements for any of our residents, due to data protection rules.

The EDP put a number of detailed questions to Buckingham Palace regarding which of his many properties the monarch personally pays the council tax on, along with which is considered his main residence for tax purposes.

An aide responded: "Council tax is paid for privately for private residences.

It is a similar story elsewhere for the King.

For the bill for the monarch's beloved retreated at Balmoral Castle, where he loves to fish for salmon in the Dee and paint watercolours amid the glens has already gone through the roof.

A council spokesman said: "Aberdeenshire Council implemented the additional 100pc charge for second homes from April 1, 2024. This has been applied to all properties classified as a second home. 

The extra tax portion of this will add an extra £3,413.88, meaning a total bill of £7,918.68

Cotswold District Council which covers Highgrove House near Tetbury, in Gloucestershire, has also voted to implement the 100pc extra council tax on second homes from next April.

The King is reported to rent the property from the Duchy of Cornwall for use as a country retreat.

Council tax or business rates bills for royal palaces such as Buckingham Palace, St James's Palace and Windsor Castle are met by the Sovereign Grant - the taxpayer-funded £86,300,000 settlement from which the King and senior royals use money to pay for what the BBC describes as "expenses related to their official duties".

It added "the vast majority" was spent on the upkeep of properties and staff costs.
