At Willow Alexander Gardeners, we believe gardens should be as sustainable as they are beautiful. As part of the House of Willow Alexander family of brands, we are proud to deliver London’s most sustainable, zero-emissions garden maintenance service, trusted by thousands of customers every month.
From Chelsea townhouses to Dulwich family homes, Balham balconies to Clapham terraces, our gardeners are helping London grow greener, one visit at a time.
Thousands of Customers, Zero Emissions
Every month, our teams complete over 2,000 zero-emission service visits across London and the South East. Powered by our all-electric fleet and sustainable tools, every journey is certified carbon neutral.
Since 2020, we’ve proudly held Carbon World Carbon Neutral International Standard Certification (Scopes 1, 2, and 3) from One Carbon World in association with the United Nations, offsetting thousands of tonnes of CO₂. That means every lawn we cut, every hedge we shape, and every garden we tend is delivered with no environmental cost.
Carbon savings at scale: compared with diesel vans, our electric fleet prevents the release of 300–400 tonnes of CO₂ each year — the equivalent of planting over 16,000 trees across London.

Innovation for a Greener Future
Garden maintenance isn’t just about today — it’s about creating a sustainable system for the future. That’s why we are part of the wider HoWA Operating System, developed by the House of Willow Alexander.
At its core is The House Companion, our pioneering diagnostics engine. It learns the unique needs of each property and provides tailored maintenance plans, eco-friendly recommendations, and seasonal advice — making it easier for every customer to live more sustainably.
The wider group has invested over £700,000 into new technology and secured an independent IP valuation of £5 million, ensuring that our innovation is as future-proof as our gardens.
Expanding Across London
Our gardeners are already trusted in Chelsea, Dulwich, Balham, Clapham, London Bridge, Sevenoaks, and North London. With the opening of our new West London branch, we are scaling further, bringing sustainable garden maintenance to even more communities across the capital.
Whether it’s a balcony in Battersea or a lawn in Hampstead, Willow Alexander Gardeners is here to help London grow greener.
People at the Heart
Behind every service are our skilled gardeners — trained professionals who bring craftsmanship, dedication, and care to every garden. They are supported by our office teams, who ensure every visit runs smoothly, on time, and to the highest standards.
It is this combination of people, process, and passion that makes Willow Alexander Gardeners one of the UK’s most trusted sustainable gardening services.
