Climate change project volunteer jobs in London

Ashden’s mission is to showcase outstanding climate solutions and accelerate systemic change that unleashes their transformative potential. Our vision is of a world where everyone enjoys access to clean energy. Where people and nature thrive.

For over 25 years, Ashden has worked with enterprises and organisations in the UK and the Global South to find, champion and scale solutions to the climate crisis. We excel in storytelling that connects these solutions with the policymakers, funders and investors poised to help them scale and maximise their impact.  Our support is expanding access to affordable clean energy to farms, villages and refugee camps in the Global South. In the UK, we are helping create warmer homes, greener schools and accelerating climate action across our towns and cities.

Ashden is a highly regarded and well-connected organisation with a strong brand and a track record of building meaningful relationships with high value and high-profile individuals. We are excited to build on the good work already achieved to further scale fundraising in this area.

You will be joining Ashden at a pivotal moment. In 2024, we launched our Changemakers campaign to secure mission-aligned funding from donors making four and five-figure gifts and beyond - a programme you will personally lead and continue to shape and develop - an exciting opportunity to nuture an emerging initiative by stewarding and uplifting current donors whilst attracting new supporters. Working in close partnership with the Director of Business Development, you will also proactively support the prospecting, cultivation and stewardship of both new and existing donors to secure transformational seven-figure gifts. As our Major Donor Lead you will have the opportunity to define, refine and strengthen our major donor proposition more broadly, securing both unrestricted and restricted income to support our long-term impact.

We’re seeking an experienced fundraiser with a track record of securing major gifts and building strong relationships with high-net-worth individuals. While climate or environmental exposure is not essential, alignment with Ashden's values and passion for driving systems change is crucial. You’ll be supported by a collaborative team, including senior leadership and Trustees, and will have key strategic and operational input into the success of our fundraising, the growth of the team, and the broader impact of our charity.

This is a stimulating and rewarding opportunity for someone looking to develop their career within a highly collaborative, passionate and visionary organisation. It is also an outstanding opportunity for those keen to deepen their experience and insight in philanthropy at the highest levels, including meaningful exposure to pioneering venture philanthropy and innovative impact-led funding models.
