Street parties in Putney and Chelsea will be given the royal seal of approval on Sunday afternoon.
The Duke of York and his daughters Princess Eugenie and Beatrice are scheduled to drop in on a lunch at All Saints Church in Putney, south west London.
They will follow this up with a trip to a party at Christchurch Street in Chelsea.
Despiter the rainy weather 10,000 street parties were expected on Sunday, as Britons came together to celebrate the Jubilee.
More than 9,500 roads were closed, and thousands more church halls, parks and gardens were filled with revellers.
