About Jobs in London

London is one of the world's top three cities for international affairs, alongside Brussels and Geneva. As a permanent member of the UN Security Council's host nation, a leading financial centre, and home to a vast network of think tanks, NGOs, and multilateral institutions, London offers unparalleled career opportunities in global policy and diplomacy.

Key international employers headquartered in London include the European Bank for Reconstruction and Development (EBRD), the International Maritime Organization (IMO), and the Commonwealth Secretariat. The city hosts world-renowned think tanks such as Chatham House (the Royal Institute of International Affairs), the International Institute for Strategic Studies (IISS), the Overseas Development Institute (ODI), and the Royal United Services Institute (RUSI). Major international NGOs including Amnesty International, Save the Children, Oxfam, ActionAid, WaterAid, and Christian Aid all have their global or UK headquarters in London.

Salaries in London's international affairs sector vary significantly by employer type. Think tank research roles typically pay £30,000–55,000, while senior policy positions at international organizations like EBRD offer £70,000–150,000+. NGO salaries range from £28,000 at entry level to £80,000+ for directors. The UK government's Foreign, Commonwealth and Development Office (FCDO) and British Council also offer substantial international affairs careers based in London.

Brexit has reshaped London's international landscape but has not diminished its global standing. While some EU-focused roles have shifted to Brussels, London has strengthened its position in Commonwealth affairs, transatlantic policy, and Global South engagement. The city's world-class universities — LSE, SOAS, King's College London, and UCL — produce a steady pipeline of international affairs talent and host influential research centres.

Compared to Geneva's focus on multilateral and humanitarian organizations, and Brussels' concentration on EU institutions, London excels in policy research, international development, human rights advocacy, and private-sector international consulting. Many professionals build careers across all three cities.
