The short answer: a hosepipe ban restricts using a hosepipe connected to the mains, not car washing itself. Washing with carried water stays legal, which is exactly how every Yikes wash already works: the cargo e-bike brings around 30 litres and uses controlled rinsing instead of an open hose. We explained it live on GB News.
A Temporary Use Ban, to give it its legal name, restricts specific uses of a hosepipe that draws from the mains supply: watering the garden with one, filling a paddling pool, and yes, washing a private car with one. Break it and the water company can prosecute, with fines up to £1,000. What the ban does not do is outlaw clean cars. Washing with a bucket has always remained permitted, and a professional wash that brings its own water is outside the restriction entirely, because no hosepipe ever touches your mains.
Yikes never plugs into your tap in the first place. The cargo e-bike arrives with its water on board and the wash uses measured, controlled rinsing, which is why an average car takes around 30 litres against the 150 litres or more an open hose can pour away. In a drought summer that difference is the whole point: the ban exists to save water, and a method that uses a quarter of the usual amount is working with the ban, not around it.
When the 2026 restrictions hit London, GB News had us on live to explain how car washing carries on lawfully through a ban and why the water maths favours carried water. You can watch the clip on our blog.
Spray-and-wipe waterless products have their place on a lightly dusty car, but on London grime they push grit across the paint, and a season of that shows up as swirl marks. Low water beats no water: enough liquid to lift and carry the dirt away from the surface, applied with control rather than volume.
