The purpose of these stalls is to provide free information and interactive activities on green subject matters for the general public.We have a limited number of spaces available across both days so please do register your interest as soon as possible. Stalls will be provided on the day.Please note: We kindly ask that you don't sell anything on your stall as we would need to get permits from the council for this. Additionally, as a charity ourselves we cannot allow other charities to fundraise in our building. So, while we warmly welcome awareness raising, engaging with community, informing visitors about your work, educational activity and signposting thorough mailing list sign ups etc. we respectfully request that there be no donation boxes or direct debit sign up on our site.If you are interested in applying for a space for your stall, then please fill out the below application form:Stallholder application form Manage Cookie Preferences
