The royal household receives £15 million a year from my Department to meet the costs of property maintenance; utilities; telephones and related services at the occupied royal palaces in England. As given in the Royal Public Finances Annual Reports 2007-08, copies of which are in the Libraries of the House (http://www.royal.gov.uk/output/page3954.asp), the maintenance costs of the occupied royal palaces for the year to 31 March 2008 (the most recent year for which there are figures) were:
Maintenance costs (£ million) Buckingham Palace 5.9 Buckingham Palace Mews and Gardens 2.1 St. James's Palace 1.5 Clarence House and Marlborough House Mews 0.8 Kensington Palace 0.7 Hampton Court Mews and Paddocks 0.3 Windsor Castle 3.7 Windsor Castle Royal Mews 0.7 Windsor Home and Great Parks 0.7
Most of these costs were met from the grant in aid, the remainder from income from a facilities management charge paid by the Royal Collection Trust, £1.8 million in 2007-08.
