The Naval and Military Club, known informally as The In & Out, is a private members club located in St James's Square, London, originally for gentlemen of the British Armed Forces. It now accepts both female and male members.

The Club was founded in 1862 by six officers, chiefly from the Buffs, because the three then existing military clubs in London – the United Service, the Junior United Service, and the Army and Navy – were all full.


The Club was formerly based at Cambridge House at 94 Piccadilly, opposite Green Park. It came to be known as "The In & Out" from the prominent signs on the building's separate vehicle entrance and exit gates. In 1996, the club purchased its current premises at 4 St James's Square, designed by Edward Shepherd in 1679 for Anthony Grey, 11th Earl of Kent and the former London home of Waldorf and Nancy Astor from 1912 to 1942. After a programme of refurbishment the club took up occupancy on 1 February 1999. To perpetuate its traditional nickname, the words "In" and "Out" were painted on the two flanking columns of the portico of the house.

In 2011 Cambridge House, in disrepair, was acquired by property tycoons David and Simon Reuben. They planned to convert the Grade I Listed Building into a 48-room private house with a value estimated at £214 million but this plan was axed in 2017 in favour of a 102-room hotel and four serviced apartments.[1][2][3]


The Club has dining, banqueting and bar facilities, and 52 bedrooms available to members. At the front entrance, in keeping with the traditions of "Clubland", a dress code is imposed (jacket and tie for gentlemen, and equivalent for ladies, although "military dress can, of course, also be worn"). The rear entrance in Babmaes Street, just off Jermyn Street, is less formal: it allows direct access to the business centre, gym, swimming pool and "The Goat" bar and brasserie.

The Club co-operates closely with and shares its premises with the Norwegian association Den Norske Klub and the Latin American Canning Club. It also provides a home for the Fleet Air Arm Officers' Association and the International Wine and Food Society.

Membership and subscriptions

The Club's President was Prince Philip, Duke of Edinburgh, who had been a member since 1947.

Notable past members include Prince Louis of Battenberg, Louis Mountbatten, 1st Earl Mountbatten of Burma, Field Marshal the Earl Roberts, John Jellicoe, 1st Earl Jellicoe, Douglas Haig, 1st Earl Haig, Redvers Buller, David Niven, T. E. Lawrence, and Robert Falcon Scott, who is commemorated on the Club's Roll of Honour.

The Club includes a total of thirty-three past members who have been awarded either the Victoria Cross or George Cross. All current recipients of these awards are honorary members of the Club.

Notable current members include Prince Andrew, Duke of York, William Astor, 4th Viscount Astor, Khalid bin Sultan, Michael Boyce, Baron Boyce, Peter de la Billière, and Peter Wall, who is the current Vice-Chairman.

Membership, long restricted to military officers, now includes those who have not served in the armed forces. Members are, however, expected to respect service traditions.

The Club no longer publicises its fees which are now only made available on receipt of an application form. Prospective members are normally required to have a proposer and seconder, both of whom must be members of two years standing, although in exceptional circumstances the Membership Committee may consider applicants without sponsors, following an interview with the Club Secretary. Serving officers in the armed forces are not required to provide sponsors but are asked to provide evidence of current service.
