King Charles is now personally financing his younger brother's living arrangements
Royal staff are understood to be uncertain how to address Andrew Mountbatten-Windsor, who had his HRH, prince and duke titles removed by King Charles last year following allegations about his connections to convicted paedophile Jeffrey Epstein.
Employees have reportedly been instructed that "Sir" remains the appropriate form of address despite his dramatic fall from grace.
One source claimed: "He's lost his HRH, prince and duke titles and so staff, who didn't know how to correctly address him, have been instructed that he is still to be called 'Sir'.
"He will be given his own chef and valet at Marsh Farm, which is a climbdown to the luxury he was previously afforded."
These two positions have yet to be filled, with recruitment pending his eventual move to the permanent residence, according to The Sun.
The contrast with his previous lifestyle could hardly be starker. At Royal Lodge in Windsor, he enjoyed the services of valets, chefs, butlers, housemaids and cleaners, with additional staff attending to him at his former Buckingham Palace apartment.
King Charles is now personally financing his younger brother's exile and retirement. Taxpayer funds will not cover his legal defence costs.
Wood Farm serves as a temporary arrangement while Marsh Farm undergoes renovation work funded by the King, though progress has stalled in recent days.
Security fencing, satellite television and new doors have been fitted, with carpets sourced from other royal properties, but insiders describe the spending as minimal.
A source claimed: "It's not as luxurious as you'd expect and nothing like he would be used to."
Mr Mountbatten-Windsor found himself spending the weekend in solitude at Wood Farm on the Sandringham estate, following his dramatic arrest on suspicion of misconduct in public office.
Police descended on the property at 8am on Thursday, which happened to be his 66th birthday, detaining him for 11 hours before returning him to the residence.
The former royal appeared visibly shaken in the back of a Range Rover when he arrived back at approximately 7pm from Aylsham police station in Norfolk.
His only companions at the property are thought to be seven dogs, including two corgis that belonged to the late Queen Elizabeth II, along with police officers and security personnel stationed outside.
Eyewitnesses reported smoke visible from the chimneys while the bedroom curtains remained drawn as officers continued their patrol.
Local residents expressed little sympathy following his arrest. A Windsor dog walker named Ben remarked: "I wasn't surprised at all. I think the mood of the nation is behind the fact that he should answer for whatever he's done."
Mr Mountbatten-Windsor has always strenuously denied wrongdoing.
