Harry was given Nottingham Cottage a 2 bedroom cottage presumably rent free. He was given security paid by the taxpayers. He was also given a clothing allowance from Charles to pay for clothes for formal public occasions.
But he obviously had little access to money. He bought his casual clothes cheap from TK Maxx and talks about drying shirts on radiators.
When he told Charles he was going to marry Meghan Charles said he could not afford to pay for Meghan and Harry as he was already paying for William and Catherine. Charles suggested Meghan continued working to pay for Garry and Meghan. Meghan paid for furniture from Ikea and sofa.com to improve the furnishings in Nottingham Cottage.
Charles paid for Harry and Meghan's wedding. Although Meghan paid for her own wedding dress. The taxpayers paid for the security.
Remember Harry and Meghan were working Royals.
The taxpayers paid for the renovation of Frogmore Cottage. A cost that Harry and Meghna paid back when they left the Royal Family.
The Civil List used to give a defined amount to each working Royal. But that was changed and all the money went to the heir to dole out.
The Queen and Charles appear to be remarkably stingy towards their own child and grandchild.
