Join our community of leaders, movers and shakers committed to empowering London’s #RefillRevolution

Start your #OneLess journey

1. Make the #OneLess pledge

All change starts with a commitment. Make that commitment today. Pledge to eradicate single-use plastic water bottles in your organisation or business and embrace refilling instead. To help you on your way we’ve created a folder of handy #OneLess support materials, which we’ll give you access to once you’ve pledged.


2. Join the #OneLess pioneer network

Ready for action? Join our network of pioneers and lead the way in making single-use bottled water a thing of the past.

Our pioneers are all actively taking steps (however small) to jump-start a refill revolution in London and to eradicate bottled water.

Together they are innovating new solutions and business models that keep our city hydrated and our ocean healthy. They are ridding businesses, venues, events, shops and places of single-use bottled water. They are redesigning London’s drinking water infrastructure so that it supports refilling. They are changing behaviour and social norms.

Get in touch with us to find out how you can join the #OneLess pioneer network.

What you’ll get out of it

Leading the wave of change isn’t always easy.

We aim to help our pioneers to:

  • Solve challenges they are encountering
  • Showcase their achievements
  • Learn from others, and access new insights and solutions
  • Connect with the right people
  • Start collaborations and build partnerships

It seems like a lonely battle sometimes, bringing a concept to market; this collection of people showed me that lots of people across the spectrum of public and private sectors are applying themselves to solving the problem of single use plastics. It was very motivating. Good job #OneLess.

It was my first opportunity to meet the wider #OneLess community. Therefore it was extremely useful to see the bridges that have already been built and realise the potential to connect much more than before.

Meeting other like minded people and the discussion that follows has been inspirational and hugely encouraging to realise that this objective might really be possible.

Joining the #OneLess Network was an obvious choice for King’s College London, as it mirrors our own vision to make the world a better place through our teaching and research. It’s exciting to work with #OneLess to develop concepts and help solve part of this systemic single-use plastic problem.
Our challenge is to make it as easy as possible for our staff, students and visitors to find water refill points within our campuses, and to address negative perceptions around tap water such as taste, health and hygiene.
