Dive into lasting impact: Fundraise for East London Waterworks Park to create and shape natural swimming ponds, ecological habitats and community gardens

East London Waterworks Park is a volunteer-led charity that has won a 2024 New London Architecture award and raised £2m towards buying land from the Department for Education to transform the 14-acre Thames Water Depot on Lea Bridge Road on the border of Waltham Forest and Hackney, into a new biodiverse park with natural swimming ponds, forest schools and community spaces. 

If you would like to help us develop our digital fundraising and our online offer, would you like to join our fundraising and communications teams in creating and implementing a strategy? We would love to hear from anyone with experience of fundraising online or with enthusiasm and a desire to test things out and learn as you go along. Recently we raised over half a million pounds through our Crowdfunder. Now we are looking to create a sustainable medium term income stream online.

The Fundraising Circle currently meets fortnightly on a Thursday evening on Google Meet and spends voluntary time outside of the meeting completing agreed tasks remotely. We understand that people may not have a lot of time to give, so we want to find volunteers who could give us one-off or ongoing strategic advice and support.

If you have experience in writing grants and funding applications, corporate fundraising, philanthropy, or any other aspect of fundraising, it would be great to hear from you. 

We are keen fundraisers but we are lacking professional in digital fundraising expertise and experience and we would love your help and input. We would welcome one-off advice on the phone or in person, as well as longer term volunteers. 

East London Waterworks Park is an exciting and ambitious project that offers many rewarding opportunities for our volunteers. You will have a significant impact on the creation of a new biodiverse community-owned park with free access natural swimming ponds and forest schools. 

By leading fundraising projects that explore how diverse professionals (architects, ecologists, web developers, community researchers etc.) collaborate to shape community infrastructure, volunteers will directly contribute to the development of a park that truly reflects the needs and desires of the local community. 

Without funding we won’t be able to make it happen. Your input will help us craft experiences that inspire, educate, and engage our service users, stakeholders, funders, and the general public, ultimately driving support for the park's mission and ensuring its long-term sustainability. So you will be directly contributing to the creation of a new biodiverse community-owned park with free access natural swimming ponds.

Our County Representatives (CR) will support our Fundraising Team by being the public face of Combat Stress in their local county, and will help build support from individuals and groups by raising awareness and funds.

Hours:The role is flexible. You can give as much or as little time as you are able. However, we do ask you ideally commit enough time to build meaningful awareness and support on your base.

What are the benefits of volunteering for Combat Stress?

• A full induction to Combat Stress and its work, including training and appropriate materials to support you in the role such as t-shirts, banners and cheer sticks. 
• Ongoing support, advice and guidance from the Senior Challenge Officer. • Learn and develop fundraising skills.
• Meet new people and be actively engaged in your local community.
• Helping our fundraisers to feel great and keeping them motivated throughout their challenge.
• Receive reimbursement for out of pocket expenses 
• Be part of the UK’s leading Charity for veterans’ mental health.
