At House of Willow Alexander, we are proud to lead as London’s most sustainable zero-emissions home and garden service provider and the UK’s most loved home & garden lifestyle brand. From Sevenoaks to Chelsea, through London Bridge to Dulwich, Balham, and Clapham, our fully electric fleet delivers over 2,000 zero-emission visits every month — proving that premium craftsmanship and sustainability can thrive together.
Every visit represents more than just exceptional service — it’s a measurable step towards a greener London.
Certified Carbon Neutral — Year After Year
We are proud to have been awarded Carbon Neutral Certification every year since 2020 by One Carbon World in association with the United Nations, achieving Gold Standard across Scopes 1, 2, and 3 .
In that time, we have offset thousands of tonnes of CO₂, ensuring every journey we make and every service we deliver — from garden care to laundry — is genuinely zero emissions.
Carbon impact: A single diesel van driving 12,000 miles a year produces ~3.2 tonnes of CO₂. With a fleet of 11+ electric vans completing 24,000+ zero-emission visits annually, we prevent the release of an estimated 300–400 tonnes of CO₂ into London’s atmosphere every year. That’s the equivalent of planting more than 16,000 mature trees.

Innovation for a Greener Future
At House of Willow Alexander, we believe the future of home and garden care lies in combining craftsmanship with cutting-edge technology. That’s why we have recently invested over £700,000 into new innovation, laying the foundations to scale the House into a true household name across the UK.
At the heart of this innovation is our soon to be released AI diagnostics engine, The House Companion, an integral part of the HoWA Operating System and membership. Designed to understand the unique needs of every home and garden, it provides eco-friendly recommendations, tailored maintenance plans, and seasonal guidance — making sustainable living simpler, smarter, and more accessible for everyone.
With our intellectual property independently valued at £5 million, this technology doesn’t just reflect our vision — it demonstrates the strength, scalability, and long-term impact of the House of Willow Alexander as we continue to grow nationwide.
Expanding Across London
We’re growing fast. Alongside our South East London base, we are opening a West London branch, enabling us to serve even more customers across Balham, Clapham, North and West London, and beyond.
From window cleaning in Chelsea to garden design in Dulwich, laundry in Balham to handyman services in Clapham, our services are trusted across Greater London — and soon nationwide.
