Could a Drought Water Ban Prevent Car Dealers from Washing Vehicles?
Southern Water’s drought ‘non‑essential use ban’ could stop car dealers from washing cars. Find out the impact and timeline for your showroom.
What is a non‑essential use ban (NEUB)?
A non‑essential use ban is a formal restriction that stops businesses from using mains water for activities deemed non‑critical. In Southern Water’s current application, the ban would cover vehicle washing, window cleaning, garden watering and the filling or maintenance of non‑domestic swimming pools. The measure is intended as a precautionary step when water resources are under severe stress.
Why Southern Water is applying for a drought order
Southern Water supplies the majority of Hampshire and the Isle of Wight. The company normally abstracts between 550 million and 560 million litres of water a day, but recent hot weather has pushed demand above 660 million litres. Flow levels in parts of the River Test – the main source for Southampton and the Isle of Wight – have fallen to roughly half their usual levels. In response, the water board has asked the government to impose a NEUB for its region, potentially affecting more than 27 million people.
Potential impact on car dealerships
For dealers operating in the affected area, a ban on vehicle washing would directly affect day‑to‑day operations. Valeting, final preparation of new and used cars, and vehicle hand‑over processes all rely on access to mains water. Without it, dealerships may have to postpone deliveries or seek alternative water sources, adding cost and complexity.
Geographical reach
The proposed order would cover the Southampton West supply area – around 165 000 residents – and towns such as Portsmouth, Fareham, Gosport, Havant and Chichester. Bognor Regis is not included because its water is supplied by Portsmouth Water, a separate provider.
Government response and decision timetable
Environment Secretary Angela Eagle has 28 days to consider Southern Water’s application. No NEUBs have been issued in the UK since 2006, with the previous one dating back to 1996. Defra (the Department for Environment, Food and Rural Affairs) has stated that any order must be balanced against impacts on nature and people, and that the government is prepared to act to protect water supplies.
What dealers can do now
While the decision is pending, dealers can begin contingency planning. Options include arranging temporary water tanks, adjusting wash schedules, or using water‑efficient cleaning methods. Southern Water encourages stakeholders to engage early – a short survey is available for showrooms to share their concerns and suggestions.
Dealer organisations also provide useful resources: industry newsletters, a WhatsApp breaking‑news group, daily email bulletins and a regular podcast covering the latest developments. Staying informed will help businesses adapt if the ban is confirmed.
