RainCatcher

RainCatcher is a UK manufacturer specialising in rainwater collection systems for domestic and light commercial use. Their range includes slimline water tanks, wall-mounted butts, and freestanding storage units designed to make rain harvesting simple and space-efficient. With discreet styling and rugged construction, each tank is easy to install and ideal for garden irrigation, vehicle washing, or topping up greywater systems.

Alongside tanks, RainCatcher supplies the full kit of harvesting accessories - including filter diverters, downpipe adaptors, linking kits, taps, and pipework. These components allow users to build complete, self-contained systems that channel roof water directly into storage. Whether you're setting up a single tank or connecting multiple units, RainCatcher offers practical, plug-and-play solutions that help reduce mains water use and support long-term sustainability.
