Non-essential use bans: what an England drought order means for business water
Milvian AI teamFacilities and infrastructure intelligence
A non-essential use ban is a drought order that lets a water company in England restrict named business and non-domestic uses, such as vehicle washers, cleaning premises and cisterns in closed buildings. It needs approval from the Secretary of State. Three companies applied in 2026 and none had been granted by 23 October, so sites have time to find which of their lines a ban would hit.
Where England stood in the week to 22 October
The government declared severe drought on 15 October in parts of Cornwall, Devon, Dorset, Somerset, East Sussex and West Sussex, after the driest April to September in over a century. The Environment Agency says 82 percent of England remains in drought.
National reservoir storage was 54 percent, about 22 percent below normal for the time of year, and England had received 52 percent of its long term average October rainfall. Hosepipe bans were in force across all or most of seven water companies' areas and parts of three more.
Hosepipe ban or non-essential use ban
| Point | Temporary use ban (hosepipe ban) | Non-essential use ban |
|---|---|---|
| Legal power | Section 76 of the Water Industry Act 1991. | An ordinary drought order under the Water Resources Act 1991, with the uses set by the Drought Direction 2011. |
| Who decides | The water company, without ministerial approval. | The Secretary of State, on the water company's application. |
| Who it mainly affects | Household uses, such as garden hoses and filling private pools. | Business and other non-domestic premises. |
| Status in late October 2026 | In force in many areas. | Applied for by Southern Water (31 July), South East Water (2 October) and South West Water (6 October). None granted. |
What a ban can cover, and what to measure
| Use a drought order can restrict | Where it hides on a site | What to meter |
|---|---|---|
| Watering plants on commercial premises | Planter and lawn irrigation on timers that nobody reviews. | The irrigation feed, read daily. |
| Filling or maintaining non-domestic pools and ponds | Makeup water on leisure pools and water features. | The makeup line, so evaporation and leaks show apart from refills. |
| Operating mechanical vehicle washers | Fleet wash bays at depots and distribution sites. | The wash bay supply, with run time. |
| Cleaning non-domestic premises and windows | Hose points on loading docks, car parks and facades. | External taps on a shared line, or a clamp-on meter during the drought. |
| Cleaning industrial plant | Clean in place cycles and wash-down hoses. | Each wash-down line, split from process water. |
| Suppressing dust | Construction and yard sprays. | The hydrant or bowser fill point. |
| Operating cisterns in unoccupied buildings | Urinal flush controllers that keep cycling in closed buildings. | Washroom lines, compared with occupancy. |
The cistern clause is the one most sites miss
Irrigation and vehicle washing are easy to switch off by hand. A flush cistern in a closed office, school or warehouse is not, because nobody is there to hear it run, and it shows up only as flow during hours when the building should draw almost nothing.
Aqueduct compares each washroom line with the building's occupancy, either from sensors or from a schedule, and flags flow during unoccupied periods. The same view separates a cistern that keeps cycling from a slow leak, because a cistern draws in regular steps while a leak draws a steady line.
Five things to do before a decision
- Check your supplier and retailerMost business customers in England buy water through a retailer, but the drought order comes from the wholesaler that supplies the area. Confirm which company's application covers each site.
- List uses against the restricted purposesWalk each site with the table above and write down every line that would fall under a ban, with who owns it.
- Meter what the bill hidesFit meters on irrigation, wash bays and external taps now. A monthly bill cannot show which use stopped.
- Set a night flow baselineRecord what each building draws when it is closed. Anything above that baseline during a ban is the first thing to find.
- Keep the evidenceDaily readings by line show that restricted uses stopped, and they show the volume saved when the water company asks.
Where this is going
The Environment Agency says some areas need 120 percent of typical rainfall over the next six months to recover. The reservoir refill season starts on 1 November, and the National Drought Group meets on 28 October.
If the three applications are approved in a dry winter, bans could land on sites that have never measured which uses they would have to stop. Sites with line-level data can comply in a day and prove it; the rest will guess.
