SmartCitiesWorld Summit is the flagship city-focused
event during London Climate Action Week

Ahead of the SmartCitiesWorld Summit on Wednesday 24 June at County Hall, we wanted to share a brief update following the heat warning issued for London. The venue is fully air-conditioned, including the conference rooms, exhibition and networking areas, so delegates will be able to enjoy the day in a comfortable environment.
With high temperatures forecast, we also recommend arriving early where possible. Hot weather can sometimes cause disruption across London’s transport network, so please allow extra time for your journey, particularly if travelling by rail, Underground or bus. Registration opens from 08:30, with refreshments available before the conference programme begins at 09:00. Water will also be available throughout the day, and we encourage delegates to stay hydrated.
Address: County Hall, Belvedere Road, London, SE1 7PB, UK
The in-person day of the Summit will take place at London’s County Hall – the former seat of the London County Council and its successor, the Greater London Council. It is situated on the South Bank of the River Thames beside Westminster Bridge, and opposite the Houses of Parliament.
The venue is as stunning on the inside as it is on the outside, providing the ideal location for delegates who may be attending from national, regional and local governmental authorities.
The in-person agenda will not be streamed live and spaces are limited to 400 delegates. We are giving priority to guests working for city, regional and local authorities. This may mean that your registration could be reviewed by our event curator. In these instances we will confirm your place once you apply.
We are offering a 20 guaranteed private sector delegate tickets to the in-person day. These tickets will be pre-approved and you won’t be able to canvas our public sector audiences. Ticket prices are £495+ vat. If you are interested in this option please contact johno@smartcitiesworld.net

The 2026 Summit also has an online component in the form of two series of must-attend webinars. The first will take place during London Climate Action Week in the days around our in-person Summit, and the second will take place during COP31 towards the end of 2026.
Each webinar will be hosted on Zoom with an option to register for individual sessions or the entire series. More information on these series will be added to our agenda page in due course
