Could you be the next winner?

What could you do with a £20k seed fund and help and advice from City Hall to get your idea started? Solveiga's Bump Mark is a new expiry label which goes bad exactly when the food inside the package does. Just run your finger across the label, if it is smooth you are good to go, if it is bumpy then be cautious. This new labelling aims to reduce food waste by telling us more about the state of our packaged food.

Caroline and Vivien are also helping to reduce waste with their online clothes swapping website Clotho London. Students drop off their unwanted clothes at 4 university locations and gain credit to spend on the website. The clothes are then sorted and highest quality items are listed for sale letting people refresh their wardrobes as often as they like but keeping waste low. They plan to use the money to set up more drop off locations. See a full list of past winners, runners up and finalists 

Everyone who applies can choose to have a chance of one of up to six paid internships with competition sponsors Siemens. Previous interns have worked in everything from finance to IT and marketing. You can read interviews with previous interns here.

Frequently Asked Questions

Below are answers to the questions we're asked most often. Otherwise email us at

Who can apply in 2016?

  • you must be, or have been in 2015, a student from a university or college within Greater London. You'll need to submit proof you were a student in 2015, like a scan of your student ID / graduation certificate showing the date
  • you must be over 18 on 30 March 2016

Do all team members have to be eligible to enter the competition?
No, you can choose whoever you want for your team, as long as the lead member is eligible. 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. You should agree who owns the idea with anyone you discuss it with. If you're entering as a group you should agree who owns the idea before you submit. The intellectual property of any submitted ideas remain 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 to help bring the idea to market, for example on, legal advice, website development, and prototypes. It can't be used for any other expenses like living costs. The money has to be spent within a year of winning. It will be released as you need it and you must give us copies of receipts to show how you've 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 an 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 vary from from three months up to a year depending on the role. They can also start at any time of the year. The internships have up until now been based in London at Siemens sustainable cities initiative The Crystal, but other opportunities will be available in 2016.  Interns are paid London Living Wage.

Do competition winners automatically get internships with Siemens?
No. Interested applicants will be sent information when internships become available and will have to apply for roles they'd like to do.

Where do I go for more information?
