United Utilities Hosepipe Ban 2026 — Temporary Use Ban in Force from 5 August

What Is Banned from 5 August 2026

From Sunday 5 August 2026, the following activities using a hosepipe are prohibited in the United Utilities supply area under the formal Temporary Use Ban:

• Watering a garden using a hosepipe or sprinkler
• Washing a private motor vehicle using a hosepipe
• Cleaning a private leisure boat using a hosepipe
• Filling a domestic swimming or paddling pool
• Cleaning a patio, path, driveway or other outdoor surface using a hosepipe
• Cleaning walls, windows, or other parts of a building using a hosepipe
• Filling or maintaining an ornamental fountain
• Watering plants on domestic premises using a hosepipe

These prohibitions apply to residential customers on domestic premises. Buckets, watering cans and hand-held containers remain permitted for all garden and outdoor uses throughout the restriction period.

What Is Exempt

The Temporary Use Ban does not apply to all uses. The following are exempt under the statutory framework:

• Commercial car washes: Automated and manual commercial car wash businesses are exempt — the ban applies to private vehicle washing on domestic premises only.
• Commercial window cleaners: Window cleaning businesses using hosepipe equipment in the course of their trade are exempt.
• Commercial agricultural use: Farmers and commercial agricultural operators are exempt from the domestic hosepipe restrictions.
• Commercial horticulture: Businesses engaged in commercial horticulture (growing plants for sale) may apply for an exemption before 5pm on Saturday 4 August 2026. United Utilities must assess and grant this before the ban comes into effect.
• Animal welfare: Exemptions for animal welfare purposes are available. Applications must be made to United Utilities before 5pm on Saturday 4 August 2026.
• Health and safety: Uses required to prevent a risk to health or safety are exempt.

Why United Utilities Has Declared the Ban

The North West of England experienced an exceptional period of dry weather through the spring and early summer of 2026. United Utilities has pointed to the prolonged dry period combined with elevated demand during the heatwave as the primary driver. While the North West is typically one of the wetter parts of England — Lake District annual rainfall averages over 2,000mm — the spring 2026 deficit was significant enough to place pressure on the reservoir network serving the more densely populated lowland areas of Greater Manchester, Lancashire and Merseyside.

United Utilities operates a large reservoir network including Thirlmere and Haweswater in the Lake District, which feed the Greater Manchester supply system via the longest operating aqueducts in Europe. However, reservoir storage also relies on local impoundment serving towns and cities in Lancashire and Cheshire, and it is these local resources that saw the most acute pressure during the spring dry period.

The decision to declare a formal TUB rather than issue a voluntary conservation appeal reflects United Utilities' assessment that voluntary compliance alone is insufficient to protect supply headroom through the peak summer demand period. The company expects the ban to reduce demand by around 5-8% during the restriction period.

What This Means for the Supply Chain

A formal TUB covering 7 million customers across the North West is a significant operational and commercial event for the water supply chain. Several areas are directly relevant:

• Leakage and network management: During a TUB, reducing network losses becomes even more critical. Every megalitre saved through leakage detection directly offsets demand shortfall. United Utilities' AMP8 leakage programme — targeting a 15% reduction in leakage versus AMP7 baseline — will likely see prioritised call-offs during and following the restriction period. Acoustic logging, satellite leak detection and repair gangs should expect elevated activity.
• Demand management technology: Pressure management to reduce background leakage is a standard response to supply pressure events. PRV controllers, smart pressure reducing valves and district metered area flow monitoring are in active use at United Utilities throughout AMP8. The restriction event may trigger accelerated procurement in some areas.
• Water efficiency: TUBs typically prompt water companies to distribute water efficiency devices to residential customers — showerheads, tap inserts, toilet displacement bags, garden water audit kits. United Utilities' water efficiency framework suppliers should expect increased call-off activity around the ban period.
• Reservoir and storage development: The ban underlines the long-term case for new storage investment in the North West. United Utilities' AMP8 programme includes capital investment in strategic reservoir schemes. Civil contractors and ground engineering firms with North West presence should track United Utilities' capital programme updates through the coming months.
• Treatment works resilience: Higher-than-normal demand during the ban period — as customers comply with gardening restrictions but maintain indoor use — places different but still significant loads on treatment works. Works optimisation and chemical supply frameworks at United Utilities remain active throughout the period.

How to Check Your Supply Zone

The Temporary Use Ban applies to customers whose water is supplied by United Utilities. Most customers in Greater Manchester, Lancashire, Cumbria, Cheshire and Merseyside are served by United Utilities, but some properties in border areas or new developments may be served by a different licence holder. If you are unsure which company supplies your property, use the postcode lookup tool on the Water UK website or check directly with your water bill.
