Going to share this again - I'm in an online volunteer meeting at the moment for the organisation, and they're really hoping to get a lot more responses across as many postcodes as possible. It'll help them work out where to focus campaigns and events, as well as providing some valuable data on how extreme heat affects people across different aspects of their lives.
