Floodproof with Andel

Andel designs and develops innovative, industry-unique flood defence solutions and works with each customer every step of the way – from initial consultation to design, installation and ongoing after-sales support. Andel recognises a bigger role to play as an environmental services business and the challenges of climate change, which is why Andel has pledged to be a net-carbon zero business by 2025.

To support UK households, businesses and public organisations in protecting themselves and their assets from the effects of extreme rainfall, Andel has developed a turnkey package of products and services for Property Level Flood Defence. Our approach is to create a proactive chain of defensive lines to allow for a timely response to flooding caused by rainfall to protect both assets and human life.

The complete flood defence  solution for your property


Furthermore, Andel works closely with public and private stakeholders to slow the flow at an upstream level. A good example of this is the Cyclone Vortex Flow Control which restricts the flow of water in drainiage systems. And through the partnership with Leeds Coppice Workers. Andel actively supports the development of local, natural flood barriers.
