Road closure fees for street parties related to the Royal Wedding and the Big Lunch are being waived by Bromley Council.
Road closure fees, which would normally cost in excess of £550, are being postponed for both occasions.
Applications from residents and community groups for street party events must be sent to the council by March 9 in order to allow sufficient time for processing and potential road closure orders to be issued.
Prince Harry and Meghan Markle are due to marry on Saturday 19 May while the Big Lunch, which was started by the Eden Project in 2009 and is an annual get-together for neighbours, will take place on June 3.
Councillor William Huntington-Thresher, executive councillor for environment, said: “The Royal Wedding will be one of the highlights of 2018 and I expect that many residents will be looking to celebrate the occasion. It will be a great time to bring our communities and neighbourhoods together.
“I am pleased to say that our borough’s history of street parties and the community spirit it represents is continuing. I would encourage anyone wishing to hold street parties to apply in good time.”
Organisers need council permission to hold parties on the road or pavement but fees only normally apply if the road needs to be closed. Road closures are sometimes necessary to ensure the safety of people attending the party as well as pedestrians and motorists needing to access the road.
