As the cost of the Duke and Duchess of Sussex's house renovations was revealed on Tuesday, discover how the works compared to other major projects at the homes of fellow royals including the Prince of Wales and the Duke and Duchess of Cambridge. While the Sovereign Grant has paid for essential maintenance work at royal residences including Kensington Palace and Windsor Castle in the past year, some of the most expensive work is being carried out at Buckingham Palace, as part of a ten-year project estimated to cost a total of £369million.

Prince Harry and Meghan's house, Frogmore Cottage



Renovations at the Duke and Duchess of Sussex's new family home cost the taxpayer £2.4 million, according to the latest royal accounts. Frogmore House was converted from five separate apartments into an official residence for Prince Harry and Meghan and their newborn son Archie, with the majority of the work completed in the month before he was born.

Significant structural work to restore the Grade II-listed property to a single home over a period of six months was covered by the Sovereign Grant, which funds the Queen and her family’s official activities. The couple paid for fixtures and fittings privately. Sir Michael Stevens, Keeper of the Privy Purse, who is responsible for royal accounts, said "The property had not been the subject of work for some years and had already been earmarked for renovation in line with our responsibility to maintain the condition of the occupied royal palaces estate. The Sovereign Grant covered the work undertaken to turn the building into the official residence and home of the Duke and Duchess of Sussex and their new family."

Prince William and Kate's house at Kensington Palace



As revealed in the 2014 Sovereign Grant report, renovations at the Duke and Duchess of Cambridge's Apartment 1a home at Kensington Palace cost the taxpayer £4.5million over two years. The work included major roof repairs and asbestos removal, while Prince William and Kate paid privately for a second family kitchen to supplement the 'working kitchen' that is used for official events.

A ten-year renovation programme is underway at Buckingham Palace, at a total cost of £369million. The huge project aims to replace the Palace's electrical cabling, plumbing and heating, to prevent the danger of catastrophic failure leading to fire or flood, as they haven't been replaced since the 1950s.

Carrying out the work in phases over a ten-year period was found to be the most cost effective way to replace the services, and work in the past year has cost over £2.7million, covering projects such as replacing the West Range Roof at Buckingham Palace Mews, and replacing the road surface at the entrance to the Palace.

The Duke and Duchess of Kent's new home, the Old Stables


Renovation work is underway at the Old Stables, based within Kensington Palace, for the Duke and Duchess of Gloucester to move into. The couple currently live in Apartment 1, next door to the Duke and Duchess of Cambridge, but are set to downsize in the coming year. Royal accounts have revealed that refurbishment for the Duke and Duchess' new home cost £400,000. According to the report: "The scheme allows for the complete refurbishment of the property including the old and failing mechanical and electrical systems. The project commenced in January 2019 and is due for completion in summer 2019."

Prince Charles' London residence, Clarence House



When the Prince of Wales relocated from St James' Palace to Clarence House in 2003, some £4.5million was used from public funds set aside for palace maintenance to renovate the property, which was previously home to his late grandmother. Charles also spent £1.65million of his own money to cover removal costs, decorating rooms for his partner Camilla, and additional refurbishments.

The Duke of York's home, Royal Lodge Windsor


Prince Andrew was granted a lease agreement by the Crown Estate for Royal Lodge Windsor, which has been his official country residence since 2004. The Duke has paid privately for the extensive renovation works that have been carried out at the property since then, which are said to include adding a private swimming pool and cost an estimated £7.5million.
