Do all team members have to be eligible to enter the competition?

However, only the lead member and eligible team members can receive the prize money and/or be considered for an internship. Eligible members will sign a basic contract with City Hall before receiving the prize money (see an example contract here).

Should I enter as an individual or as part of a team?
You can enter as either or both.
I'm worried about confidentiality and idea ownership. How will this work?
City Hall, the Low Carbon Entrepreneur delivery team and all judges will keep your ideas confidential unless you've given written permission to, or if they're required by law to reveal the information. Titles of winning entries and brief descriptions approved by finalists may be used in publicity. We recommend you agree who owns the idea with anyone else you discuss your ideas with.  If you're entering as a group you should also agree who owns the idea before you submit. The intellectual property of any submitted ideas will remain with the applicant/s. 

Who gets the prize money for a team idea and what can we spend it on?
The prize fund must be spent with the aim of bringing the idea to market for example, legal advice, website development, and prototypes. It is cannot be used for any other expenses like living costs. The money has to be spent by June 2016. The prize money will be released as you need it and you will have to give us copies of receipts to show how you have spent it.

If I reach the final, will I get a mentor?
Yes. The winners will receive mentoring from the Low Carbon Entrepreneur delivery team.

Do I have to be interested in a Siemens internship in order to apply?
No, the internships are independent of the prize fund.  You can choose not to receive information about the internships.

Can you tell me more about the internships?
Internships range in length from three months up to a year depending on the role. They also vary in their start dates through the year. The internships have up until now been based in London at Siemens sustainable cities initiative The Crystal, but some opportunities are now coming up at other Siemens UK offices.  Interns are paid £15,000 a year pro rata.

Do competition winners automatically get internships with Siemens?
No, internships with Siemens are not automatically given to competition winners. Interested applicants will be sent information when internships become available and will have to apply for the roles they would like to do.

Where do I go for more information?
For further inspiration take a look at the London Sustainable Development Commission’s Quality of Life Indicators report.
For an interactive demonstration of the issues facing cities in the future, we recommend you visit Siemens’ urban sustainability centre The Crystal.
