As such, the Sovereign Grant is increasing too. The sovereign grant will be reviewed in 2026-27 to reassess the amount handed over to the palace and ensure it is an “appropriate level”. They’re telling the government to keep the Sovereign Grant percentage where it is for the time being because they’re still paying for the hugely expensive refurbishment/reno of Buckingham Palace, a decade-long undertaking. Royal travel costs soared by hundreds of thousands of pounds last year despite fewer engagements due to the illness of the King and Princess of Wales, figures show. The Sovereign Grant report revealed travel expenditure went up by £300,000 at a bill of £4.2m despite there being around 400 fewer visits and less foreign travel than the year before.
