About us

Cleantech for UK is a leading advocacy body representing a powerful coalition of 12 company builders and investors, spanning the innovation lifecycle—from start-ups to established IPOs.

‍This diverse group is united by a commitment to advancing Britain's clean and sustainable growth across critical industries such as manufacturing, construction, transport, and agriculture. As the government seeks to kickstart economic recovery, Cleantech for UK is at the forefront of promoting innovative technologies poised to create thousands of jobs and significantly boost productivity nationwide.

By spearheading this coalition, we champion innovations that position Britain as a clean energy superpower, advocating for zero-carbon technologies and sustainable practices that reduce emissions, lower costs, and ensure long-term prosperity.

Our broad-based advocacy and collaboration leverage the expertise of our coalition members, allowing us to support the government in achieving its key objectives: fostering sustainable growth, unlocking new opportunities, and solidifying Britain’s leadership in cleantech industries.

We invite policymakers to partner with us in shaping a greener future that prioritises economic growth, job creation, and community well-being.
