Appeal for 61 Whitehall

For 190 years we have helped the United Kingdom navigate uncertain times. Now we need help with our own future.


Our history

Founded by the Duke of Wellington in 1831, the Royal United Services Institute (RUSI) is the world’s oldest and the UK’s leading defence and security think tank. Throughout our long history, we have built a reputation as a trusted authority on defence and security the world over. In recent years, RUSI’s geographical and thematic scope has expanded to reflect the challenges of the twenty-first century – from the changing character of war, to online radicalisation, to the rise of China.

We have always been fiercely independent, because only this can ensure rigorous thinking. But free thinking doesn’t come free. We have not received a core subvention from the UK government since the early 1980s, and depend entirely on independently-raised revenue and philanthropy.

Now we need to realise the potential of RUSI’s crown jewel, our building at 61 Whitehall. We need to make the most of its location, its history, and thus its convening power.

We need to bring ‘home’ RUSI’s research staff and release the money now spent on renting external offices. We need to take RUSI into an even brighter future. And we need your help to do that.

61 Whitehall

A building worthy of our mission and our visitors is essential

61 Whitehall is a magnificent building, situated next to Banqueting House and the Ministry of Defence, close to Downing Street, and within a stone’s throw of the Foreign & Commonwealth Office and the Houses of Parliament. Combine the proximity and prestige of the location with RUSI’s standing and you have incredible convening power, bringing those working in government, security agencies and the armed forces together with research institutes, the private sector and other professional bodies. But increasingly, the deteriorating fabric of the building has negatively impacted that convening power.

In 2015 we acquired the freehold of 61 Whitehall, and in 2018 received planning permission for the bold, but sympathetic, redevelopment.

The planned renovation will:

  • Restore 61 Whitehall’s original heritage features to a high standard
  • Add state-of-the-art conference, media and meeting rooms
  • Renovate and upgrade the library
  • Add to and extend the space available for learning
  • Redevelop and extend the upper floors of the building


The effect will be to breathe new life into a very special building, allowing us to attract larger numbers of influential people and the public through our doors.

The Appeal

The costs of the redevelopment are £10 million. We invite your support, to help RUSI fill its essential role, which will not only bring immediate benefits to RUSI’s mission, but also strengthen its long-term future. RUSI makes a vital contribution to the world’s security. You can make a vital contribution to RUSI’s future.

Fundraising for the restoration, redevelopment and modernisation of our building at 61 Whitehall, is going well. With the superb leadership of Sir David Lidington, Sir John Scarlett, Sir Mick Davis and Dr Karin von Hippel, to date, just over £9 million has been secured. This includes the largest single gift in RUSI’s history, £2 million from The Exilarch’s Foundation. As a result of the fundraising success to date, building works commenced on site in January 2021 and is scheduled to be completed in Spring 2023.

RUSI is indebted to The Exilarch’s Foundation, The Starr International Foundation, The Law Family Charitable Foundation, Max Kelly, The Garfield Weston Foundation, Sir Mick Davis, Mr Laurence Geller, The Michael and Sarah Spencer Foundation, Hintze Family Charitable Foundation, Google, His Grace the Duke of Wellington, The Rothschild Foundation and many others, for their generous support.
