The 90-minute guided tours, running from January to May and costing £90 ($195.25), will offer a more in-depth look at the history of the rooms in the East Wing.
The royal residence is undergoing a £369 million refurbishment to update its electrical cabling, plumbing and heating system over the course of 10 years.
The working palace is the King’s official residence in London, where he conducts his audiences and receptions. He and the Queen do not currently stay overnight there, preferring his nearby home of Clarence House.
Guided tours of the palace’s staterooms – which do not include the East Wing – are offered already during the winter months from November to January, with some in late spring and around Easter.
Visitors will tour the Centre Room, from which they will have a view of the balcony and the Victoria Memorial, explore the Yellow Drawing Room, with its towering Chinese porcelain pagodas, and visit the 240ft (73m) Principal Corridor.
Tickets for the traditional summer opening of the staterooms from mid-July until late September, and the East Wing in July and August go on sale on Tuesday.
Meanwhile, new £1 tickets to visit Windsor Castle and the Palace of Holyroodhouse have been announced for 2025. The cut-price entrance will be available between January and April to people receiving universal credit (UK payments to help with living costs) in an attempt to make the royal residences more inclusive.
Guided tours of St James’s Palace in London, including a view of the Chapel Royal, where Prince George and Prince Louis were christened, will also be available on selected weekends in spring 2025, following trial openings several years ago.
