Do Hosepipe Bans Really Work—or Are Leaking Pipes the Bigger Problem?

A hosepipe ban may save water today, but it cannot be allowed to replace the long-term work needed to secure tomorrow’s supply.

At the time of writing, five water companies in England have announced Temporary Use Bans, commonly called hosepipe bans. Restrictions are already operating in parts of Kent, Hampshire, the Isle of Wight and the Anglian Water region, with Cambridge Water and Affinity Water restrictions due to become enforceable on 17 July 2026.

For those of us in and around Hemel Hempstead, this is no longer a distant issue. Affinity Water’s Central region ban covers much of Hertfordshire, including the HP1, HP2 and HP3 postcode areas.

Whenever restrictions are announced, the same understandable questions appear:

Do hosepipe bans really save much water?

Why should householders carry buckets while millions of litres escape from leaking pipes?

Is a hosepipe always more wasteful than a watering can?

And what happens to elderly or disabled people who cannot safely carry heavy containers of water?

The honest answer is that hosepipe bans do work, but they are a blunt emergency measure. They must be accompanied by faster leak repairs, better infrastructure and sensible exemptions for those who genuinely need them.

What Is a Hosepipe Ban Actually Trying to Achieve?

A hosepipe ban is not normally introduced because the country is about to run completely out of water.

Its immediate purpose is to reduce peak demand.

During a prolonged spell of hot weather, millions of people may water gardens, fill paddling pools, wash cars and operate sprinklers at approximately the same time. Water treatment works, pumping stations, reservoirs and local distribution pipes all have limits.

Even where there is still water available somewhere in the system, the network may struggle to treat and deliver it quickly enough to meet an exceptional evening peak.

Restrictions are therefore designed to flatten that peak, preserve stored supplies and reduce the amount that must be taken from rivers, boreholes and other environmentally sensitive sources.

The Environment Agency says that research following previous droughts found Temporary Use Bans could reduce the amount of water entering distribution networks by approximately 3–5%.

At first glance, 3–5% may not sound impressive. However, when a company is distributing hundreds of millions of litres every day, even a small percentage can represent a substantial volume of water.

That saving may help to:

• maintain water pressure;
• keep reservoirs from falling as quickly;
• reduce additional abstraction from rivers;
• protect fish and other wildlife;
• delay the need for more severe restrictions.

A hosepipe ban is therefore rather like applying an emergency brake. It may not solve the underlying problem, but it can prevent the immediate situation from becoming worse.

The Enormous Problem of Leaking Pipes

Public frustration is nevertheless entirely justified.

Ofwat reports that the water network in England and Wales lost approximately 2,869 million litres of water every day during 2024–25. That is equivalent to 46.4 litres per person per day.

It is difficult to ask someone to save a few watering cans of water without expecting them to question losses on that scale.

Ofwat also says that leakage is now at its lowest recorded level in England and that total leakage has fallen substantially since privatisation. However, the regulator is still requiring a further 17% reduction between 2024–25 and 2029–30, while the industry has committed to halving leakage from its 2017–18 level by 2050.

There has been progress, but the remaining losses are still enormous.

The public is not wrong to feel that the responsibility is unevenly distributed. A householder may be told not to use a hose for five minutes while water has been running down a road from a reported leak for several days.

That damages trust.

Water companies cannot expect enthusiastic public cooperation if customers believe the companies themselves are not acting with equal urgency.

It Is Not a Choice Between Bans and Leak Repairs

The debate is sometimes presented as though we must choose one side:

Either households reduce their consumption, or water companies repair their pipes.

That is the wrong choice.

We need both.

Repairing the network provides a permanent reduction in demand on our water resources, but replacing pipes, locating underground leaks, obtaining road closures and completing major engineering projects takes time.

A hosepipe ban can reduce demand within days.

That does not excuse slow repairs or historic underinvestment. It simply means that a long-term infrastructure problem and an immediate summer shortage must be tackled simultaneously.

Customers should cooperate during genuine shortages. In return, water companies should publish clear information showing:

• how much water is being lost;
• how quickly reported leaks are repaired;
• whether leakage targets are being met;
• what new reservoirs, transfer systems or treatment capacity are being developed;
• how customer savings compare with the company’s own progress.

Cooperation is much easier when it feels like a shared effort rather than a lecture directed only at households.

Is a Watering Can Always More Efficient Than a Hose?

This is where the restrictions can become illogical.

A hosepipe is not automatically wasteful. A watering can is not automatically efficient.

The result depends on how each is used.

Imagine that someone needs to water six large containers. Six 10-litre watering cans would use 60 litres of water.

A hose delivering 15 litres per minute and used carefully for three minutes would use 45 litres.

However, leave that same hose running for 15 minutes and it uses 225 litres.

The problem is therefore not merely the hose. It is uncontrolled flow, unnecessary watering, sprinklers, overspray and hoses being left running while the user moves around the garden.

A trigger nozzle that stops the flow immediately can be very different from an unattended sprinkler watering a lawn, pavement and fence for an hour.

Restrictions tend to focus on the equipment because that is easier to explain and enforce. A neighbour can see that a hose is being used. They cannot easily measure whether it has delivered 20 litres or 200 litres.

Nevertheless, a rule based entirely on the delivery method can produce strange outcomes. People may make numerous journeys with full watering cans, spilling water along the way, when a short and carefully controlled use of a hose could have completed the job with less water.

My Mum and the Importance of Sensible Exemptions

This is not merely a theoretical problem for our family.

My Mum has only a few plants that need watering, but she cannot safely carry a heavy watering can around the garden.

A standard watering can containing ten litres of water weighs more than ten kilograms once the weight of the can itself is included. For an elderly person, carrying that across uneven paving can be difficult and potentially dangerous.

Using a hose sparingly allows her to stand safely, direct a small amount of water precisely around each plant and stop the flow immediately.

Preventing her from doing that would not necessarily save water. It might simply make gardening impossible or place her at risk of falling.

Fortunately, many water companies recognise this. Southern Water, for example, automatically exempts Blue Badge holders and customers on its Priority Services Register with relevant medical or mobility needs.

Affinity Water’s July 2026 notice also states that Blue Badge holders and Priority Services Register customers are automatically exempt. It specifically provides for customers who are physically unable to use a watering can or bucket safely.

This is not a loophole.

It is a reasonable adjustment that distinguishes between wasteful use and necessary access.

Anyone with mobility difficulties should check their own supplier’s exact rules, as exemptions can vary, and consider joining the company’s Priority Services Register.

A Better Way to Design Restrictions

A more sophisticated system would target waste rather than treating every hose user in exactly the same way.

Restrictions could be introduced gradually.

The first stage might prohibit unattended sprinklers, filling swimming pools, washing patios for cosmetic reasons and watering established lawns. These activities can use large quantities of water without protecting valuable plants.

A later stage could limit garden watering to certain times or allow only handheld hoses fitted with trigger controls.

Efficient drip irrigation could remain permitted where it delivers water slowly and directly to the soil. Both Southern Water and Affinity Water include concessions for qualifying drip or trickle systems fitted with controls that prevent runoff or misting.

Exemptions should continue for:

• people with medical or mobility needs;
• animal welfare;
• recently planted trees and hedges;
• food crops where watering by can is impractical;
• ponds containing fish or other aquatic animals;
• genuine health and safety requirements.

The aim should be to stop excessive consumption, not to punish careful gardeners.

What Should We Water During a Drought?

Not everything in the garden needs to remain green.

An established lawn will often turn brown during dry weather and recover when rain returns. Attempting to keep a large lawn bright green can consume an extraordinary amount of water.

Limited supplies should instead be concentrated on things that may not survive without help:

• vegetables and fruit crops;
• containers and hanging baskets;
• newly planted shrubs;
• recently planted trees;
• young hedges;
• plants of particular value;
• wildlife ponds that are becoming dangerously low.

Water should be directed towards the soil around the roots rather than sprayed across leaves and paths.

Mulching around plants helps the soil remain damp for longer. Water collected from roofs can be stored in water butts, while suitable household water can sometimes be reused rather than poured down the drain.

The Environment Agency also recommends rainwater collection, repairing leaking toilets, reusing appropriate kitchen water and reducing shower time as ways of lowering demand before and during a drought. A leaking toilet alone can waste hundreds of litres a day.

Practical Ways to Reduce Water Without Abandoning the Garden

A few simple changes can make garden watering considerably more effective.

Water fewer plants properly.
Giving a priority plant a thorough drink is usually more useful than briefly wetting the surface of an entire flower bed.

Use a trigger-controlled nozzle where permitted.
The water stops when the trigger is released rather than continuing to run while moving between plants.

Collect rain from every suitable roof.
Sheds, greenhouses, garages and other outbuildings can often support additional water storage.

Protect the soil.
Compost, bark and other suitable mulches reduce the speed at which exposed soil dries.

Check toilets and outdoor taps.
A quiet internal leak may waste water continuously without attracting the attention that a visible street leak receives.

Report public leaks promptly.
Householders should save water, but they should also hold suppliers accountable for water escaping from the network.

Climate Change Is Making the Question More Urgent

The wider problem will not disappear when the next heavy rain arrives.

The UK is increasingly experiencing long dry periods interrupted by intense rainfall. A sudden storm may produce flooding and runoff without adequately restoring groundwater, reservoirs or river flows.

Water security will require more than emergency appeals to stop using hosepipes.

It will require:

• faster leakage reduction;
• better rainwater capture;
• new and enlarged reservoirs;
• transfers between water company regions;
• more water-efficient homes and appliances;
• protection of chalk streams and wetlands;
• carefully managed water reuse;
• long-term planning for population growth and changing weather.

Household conservation is part of the answer, but it cannot carry the entire burden.

So, Do Hosepipe Bans Work?

Yes, they do.

Evidence suggests that they can reduce demand sufficiently to make a meaningful difference during periods of high consumption and limited supply.

But they do not fix leaking pipes.

They do not build reservoirs.

They do not modernise treatment works.

They do not replace long-term planning.

And they should never require an elderly or disabled person to struggle dangerously with heavy buckets when a carefully controlled hose would be safer and potentially more efficient.

The sensible position is not to oppose every restriction, nor is it to accept them without question.

We should conserve water when supplies and the natural environment are under pressure. At the same time, we should insist that water companies reduce leakage, improve resilience and demonstrate that they are working at least as hard as their customers.

A hosepipe ban should be an emergency brake—not a substitute for repairing the road.
