Even the Queen won’t escape the energy price hike - with gas and electric bills at the royal buildings expected to surge to more than £4 million.
Experts reckon the 54 per cent rise announced by Ofgem last week could add more than £2million to the cost of heating and lighting the royal estate.
Buckingham Palace alone - which has 775 rooms covering 828,000 sq ft - will cost an estimated £2,039,985 per year after April 1.
