The so-called HMS Bubble team of staff will also remain at Windsor to carry out their duties.
Philip and the Queen did spend time at Balmoral over the summer and Sandringham but spent the majority of the last year in Windsor.
Before moving to Windsor to be closer to his wife, the Duke spent his days at the Wood Farm residence on the Sandringham estate.
He took up residence there after retiring from official duties in 2017.
After isolating with the Queen, the Duke of Edinburgh was admitted to King Edward VII’s hospital where he underwent treatment for a pre-existing heart condition last month.
While there, he was visited by his Prince Charles before he returned to Windsor.
Following her husband’s death, it is unclear whether the Queen will return to Buckingham Palace.
“If weekly audiences with the Prime Minister are permitted post-Covid to resume, this means Mr Johnson will have to travel from Downing Street to Windsor, while ambassadors and high commissioners may also have to present their official credentials there too.”
Away from residing at Windsor, the Queen was forced to sit alone during the service on Saturday due to covid restrictions.
Due to the restrictions, only 30 people were allowed to attend the funeral.
Lady Susan did accompany the Queen in her private car as they travelled to the service.
The Queen had personally asked Lady Susan to join her on the short journey to St George’s Chapel.
In a brief moment, the Queen appeared to wipe away a tear as she travelled in the state Bentley.
