@Puzzledandpissedoff It's in this article (and probably elsewhere)

The Daily Mail understands that despite repeated requests for clarity, no formal response to the offer of accommodation at a Royal residence for the Duke and his family had been received by the necessary deadline at the end of last week.
While every effort had, it is understood, been made to facilitate the Duke’s stay, as a courtesy to staff and others involved, the Royal Household does require a minimum level of notice to ensure he could be hosted appropriately at a Royal residence.
Since this offer was first made, every indication from the Duke and his senior team has remained that the accommodation was deemed unsuitable, including in correspondence received on Saturday morning which formally declined The King’s offer.
While a belated request was subsequently received later in the day to accept this accommodation for the Duke for a limited period, the appropriate hospitality and staffing provision was no longer available.
