Previously, councils were required to gain approval from businesses before erecting signs or street lights on their property. The new code of practice means local authorities will only have to give building owners 56 days notice of their plans.
Property owners will still be able to challenge decisions and boroughs will only be able to use the new powers after signing up to the new guidance.
Cllr Julian Bell, chair of London Councils’ transport and environment committee, said: “Street signage and lighting is essential but too often the posts and columns are ugly and intrusive. Everyone benefits from approaches which protect the look and feel of our streets.
“These new guidelines will empower boroughs to reduce the need to install more and more street furniture and reduce the cost of putting up signs and lights.
“The document has also been designed as an informative and accessible tool to help property owners understand their rights under the legislation. Our aim is that boroughs, residents and business owners will work together to protect the capital’s urban environment.”
