Early Life and Education
Seb Dance was born in London on 1 December 1981. His public career eventually developed around politics, campaigning, international development and public policy. Although he later became particularly associated with transport and environmental issues, his professional background began before his election to the European Parliament.
Dance studied at the University of Manchester. Before entering elected European politics, he gained experience working in political and development-related roles. London City Hall records that he worked for ActionAid UK and also served as a special adviser to the Secretary of State for Northern Ireland. These positions gave him experience in government, communications, campaigning and policy development.
Seb Dance and the European Parliament
A significant stage in Seb Dance’s career began in 2014 when he was elected as a Member of the European Parliament representing London. His European parliamentary career continued until January 2020, when the United Kingdom formally left the European Union.
During his time as an MEP, Dance became particularly associated with environmental and public-health policy. European Parliament records show that he served on the Committee on the Environment, Public Health and Food Safety and later became its Vice-Chair during the ninth parliamentary term.
His responsibilities included issues involving air quality, vehicle emissions and environmental regulation. He also participated in the European Parliament’s Committee of Inquiry into Emission Measurements in the Automotive Sector, established following the wider controversy surrounding vehicle emissions testing.
Dance’s parliamentary record therefore helped establish an important theme that continued into his later career: the relationship between transport policy, environmental standards and public health.
Focus on Air Quality and Vehicle Emissions
Transport and environmental policy have been recurring subjects throughout Seb Dance’s professional life. During his European Parliament career, he was involved in work concerning vehicle emissions and clean transport.
A 2024 London City Hall document describing his previous European role states that Dance served as coordinator for the Socialists and Democrats Group on vehicle emissions and spokesperson on air quality. The same document records that he was Vice-Chair of the Environment Committee and Deputy Leader of the European Parliamentary Labour Party.
His European work is also documented in parliamentary legislative records. For example, the European Parliament identifies Dance as a shadow rapporteur on legislation concerning emission limits and type approval for certain non-road mobile machinery.
These activities formed part of a broader period in which European institutions were examining air pollution, vehicle standards and the environmental impact of transport.
Career After the European Parliament
After his European Parliament career ended, Dance continued working in areas related to public policy, climate and international affairs. His experience outside elected office provided another stage in his professional development before his return to London government.
His eventual appointment to City Hall came at an important moment for London’s transport system. The city was dealing with the continuing effects of the COVID-19 pandemic while major transport projects and longer-term environmental objectives remained central to London’s policy agenda.
Deputy Mayor for Transport
In December 2021, Mayor of London Sadiq Khan announced that Seb Dance would succeed Heidi Alexander as Deputy Mayor for Transport. Dance officially began the position in January 2022.
The role places him within the senior leadership of London’s transport administration. His responsibilities include supporting the Mayor’s transport policies and working with Transport for London on the operation and development of the capital’s transport network.
London City Hall continues to identify Dance as Deputy Mayor for Transport in 2026. He has also appeared before the London Assembly’s Transport Committee alongside TfL Commissioner Andy Lord to discuss issues affecting London’s transport system.
Role With Transport for London
Seb Dance’s responsibilities extend beyond his position at City Hall. He serves as Deputy Chair of Transport for London, the organisation responsible for much of London’s public transport infrastructure and services.
The TfL Board provides oversight of major strategic matters, including TfL’s budget, business plan and delivery of the Mayor’s Transport Strategy. Dance was reappointed as Deputy Chair in 2024, and London City Hall confirmed his continued position following subsequent board appointments.
His role means that he has been involved in discussions surrounding London’s buses, Underground, cycling infrastructure, walking, taxis, private-hire vehicles and wider transport planning.
Work on London’s Transport Network
As Deputy Mayor for Transport, Dance has been involved in a wide range of transport matters. London Assembly records show that his responsibilities include overseeing the Mayor’s transport policies, including taxi and private-hire vehicle services.
In 2026, the London Assembly’s Transport Committee held a question-and-answer session involving Dance and the TfL Commissioner. Topics included accessibility and inclusion, the bus network, road safety, capital projects, automated vehicles and the taxi and private-hire sector.
This demonstrates the breadth of the transport portfolio. The position is not limited to London’s famous Underground system but encompasses many forms of travel and the infrastructure supporting them.
Personal Life
Seb Dance’s personal life has occasionally appeared in official public records because of his position at City Hall. His current register of interests states that his husband is a member of the House of Lords and a Minister of State at HM Treasury. The register also records Dance as a director of the think tank Politics Without Borders, noting that he receives no payment from that role and has suspended his duties there while serving at City Hall.
As with other public officials, the register exists to disclose relevant interests and help provide transparency around his public responsibilities.
Seb Dance Today
In 2026, Seb Dance remains Deputy Mayor for Transport and Deputy Chair of Transport for London. His career has moved through several distinct stages, from political and development work to the European Parliament and ultimately senior responsibility for London’s transport system.
What makes his professional background distinctive is the continuity between his earlier work and his present responsibilities. His European parliamentary activities included air quality, vehicle emissions and environmental policy, while his current City Hall role involves transport planning and London’s public transport network.
For readers interested in British politics, European affairs, environmental policy and London transport, Seb Dance’s career provides a useful example of how experience in one policy area can continue into later public-service roles. His work in the European Parliament and his current responsibilities in London have both placed transport and environmental questions at the centre of his public career.
