The Residents’ Society of Mayfair and St. James’s is the official amenity society recognised by Westminster City Council and the Grosvenor Estate for Mayfair and St James’s.

More than that, we are a community organisation which seeks to unify our community for social gatherings in the spirit of our neighbourhood, and to support our residents and traditional businesses to fight to protect this special place in the world. We seek to protect residential amenity, and enhance it where possible.

Our members are integral to helping us fulfill this mission. By joining the RSMSJ you lend your voices to many, so that together we can be heard and help safeguard our community for tomorrow.

Membership of the RSMSJ is £10/ year for individuals, to cover the organisation’s expenses.
