Rainwater planters are watertight containers connected directly to your roof’s downpipe.
Once installed, plant it as you wish – with wildflowers, climbers, vegetables and herbs – or use it as a wetland or mini pond!





Why Rainwater Planters?
Rainwater Planters…
SAVE WATER Plants prefer rainwater and diverting it into planters keeps mains water free for domestic use.
IMPROVE WATER QUALITY Your planter reduces heavy rain from overwhelming the sewers, releasing sewage and pollution into the river.
INCREASE GREEN SPACE & COOL OUR CITY More planting means more homes for pollinators, birds, and local wildlife, greening our neighbourhood and cooling our city.
REDUCE FLOODING Every planter takes pressure off local drains and, as water systems are all connected, this adds up to make a real contribution to flood management across London.
The Cost of Concrete
Our cities were built to move rainwater away as fast as possible.
Roads, rooftops and paved surfaces channel water straight into sewers – rather than letting it absorb slowly into the ground, filter through plants and soil, and be held in the landscape where it belongs.
The result? Flooding. Drought. Overheated streets. Polluted rivers. And biodiversity squeezed out of our neighbourhoods.
