The Christmas tree lights in Southwark Cathedral and Borough Market were switched on simultaneously on Wednesday evening during Better Bankside's annual service for local businesses and their employees.
The outdoor ceremony followed a Christingle service in the cathedral attended by children, parents, local business representatives and residents.
Better Bankside had arranged for younger children to meet Father Christmas before decorating their Christingles.
A Christingle is an orange representing the world; tied with a red ribbon as the blood of Jesus and decorated with dolly mixtures on cocktail sticks for the fruits of the earth. A lit candle on top of the orange is Jesus Christ as the light of the world.
Oranges to make the Christingles were purchased from next door Borough Market and donated by the market trustees.
Following the lighting of Christingles and the indoor tree there was a procession to the churchyard for the lighting of outdoor trees.
The Dixie Ticklers played during both the service and a reception held afterwards in a marquee.
Mulled wine and mince pies were sponsored by Shard building contractors Mace.
