Mayfair is where I&S Security Group began, and it remains the heart of what we do. Since 2006, we have provided specialist security services to some of the area's most respected restaurants, private members clubs and hotels.
I&S was founded in Mayfair in 2006, with Nobu Restaurant & Bar on Berkeley St. as our first client. In the years that followed, we built our reputation venue by venue, relationship by relationship, in one of London's most demanding and discerning hospitality markets.
Today, several of our longest-standing client relationships are with Mayfair institutions: The Arts Club, Hakkasan, Amazónico, Sexy Fish, and many others. These aren't recent wins. They are partnerships built over years of consistent, high-quality service in a neighbourhood that notices the difference.
Our registered office is at Devonshire House, One Mayfair Place, the operational home of the business since its early years. Mayfair isn't just where we work. It's where we're from.
