Since 2001, London has lost an average of 81 pubs a year and the mayor has vowed to protect them.
Mr Khan will introduce the agent of change principle in his draft London Plan, whereby developers building new residential properties near pubs will be responsible for ensuring they are adequately soundproofed and designed to reduce sound from nearby pubs, clubs and live music venues, instead of the pubs and clubs being hit with the costs.
Boroughs have been told to refuse proposals from developers who don’t clearly demonstrate how they will manage the noise impact.
The mayor’s plans to protect London pubs follow figures released earlier this year which revealed that 1,220 pubs have closed in the capital in the past 16 years.

In 2001, there were 4,835 pubs in London.
By 2016, this total had dropped by 25% to 3,615 – an average loss of 81 pubs per year.
Mr Khan said: “Pubs across the capital are often at the heart of our communities or of historic value and should be protected by local authorities in order to protect the capital’s unique character.
“From historic watering holes to new pop-up breweries, nothing defines the diverse and historic character of the capital better than the Great British pub.
“That’s why I’ve set out measures in my draft London Plan to protect pubs against redevelopment, ensure they can co-exist peacefully with nearby residential properties and ensure that councils across the capital recognise their importance to the city’s cultural fabric.”
