Thames Water hosepipe ban 2026: Who’s affected & Why

Last Updated on 4 days ago by TodayWhy Editorial

Thames Water has just told more than 10 million customers to stop using their hosepipes. The ban started at 00:01 on Thursday, 23 July 2026.

So why did Britain’s biggest water company pull this lever, who’s actually exempt, and what does it mean for you? This piece covers the original announcement plus the exemption rules readers keep asking about.

What is the Thames Water hosepipe ban?

It’s officially called a Temporary Use Ban, or TUB. It covers the 10.1 million customers Thames Water supplies across London, the Thames Valley and the Home Counties.

Under the ban, you cannot use a hosepipe for anything non-essential. That includes watering the garden, washing the car, filling a paddling pool, or topping up a hot tub.

You can still use a watering can, a bucket, or grey water from your sink or bath. Sprinklers and pressure washers are off-limits too, since they do the same job as a hosepipe.

Breaking the ban can bring a fine of up to £1,000, imposed by a court under Section 76 of the Water Industry Act 1991.

BREAKING: Thames Water issues hosepipe ban from Thursday, prohibiting all customers from using them to water gardens, clean cars, fill paddling pools, or top up hot tubs.

Why did Thames Water bring in the ban now?

The short answer: not enough rain, too much heat, too much demand.

The Thames Water region received only 40% of its average spring rainfall this year. That dry spring was followed by repeated heatwaves, including a UK record of 37.7°C reached in Norfolk on 26 June.

The result is a surge in demand right when supplies are stretched thinnest. Thames Water says water use is currently 10% above normal in the Thames Valley and Home Counties, and 7% above normal in London. Customers are drawing an extra 100 million litres a day — roughly the equivalent of adding every home in Manchester to the network.

Hot weather doesn’t just push up demand. It also puts physical strain on underground pipes, raising the risk of bursts and leaks, while reservoirs get little help from a near-rainless July.

Nevil Muncaster, Thames Water’s director of strategic water resources, said the step was “necessary to protect water supplies for everyone and the environment,” and thanked customers who had already cut back.

Who Is Exempt From the Hosepipe Ban?

This is the question Thames Water gets asked the most — including by readers of this article. Two things make you exempt on their own: holding a Blue Badge, or being on Thames Water’s Priority Services Register. Both let you keep using a hosepipe to water your garden, wash your car, clean windows, walls and paths, and fill a domestic pond.

You do not need a Blue Badge to qualify for the Priority Services Register. According to Thames Water’s own hosepipe ban FAQ page, you can register if you or someone in your household has any of the following:

• A chronic or serious illness
• Dementia or a cognitive impairment
• A physical impairment or restricted hand movement
• Being blind or partially sighted
• Being unable to answer the door unaided
• Recently returned home after a hospital stay
• Reliance on medical equipment such as dialysis, a feeding pump, automated medication, a stair lift, hoist, electric bed, nebuliser, apnoea monitor, or oxygen concentrator

Age on its own is not listed as an automatic qualifying reason. But arthritis, balance problems, or any condition that makes carrying full watering cans genuinely difficult falls squarely under “physical impairment or restricted hand movement” above. If that’s your situation, you’re very likely eligible — you just need to register rather than assume the exemption applies automatically.

How to register: Contact Thames Water directly (by phone or through their website) and ask to join the Priority Services Register. They will write to confirm your exemption once you’re registered, so keep that letter as proof if you’re ever asked.

Beyond individual exemptions, the ban also doesn’t apply to: watering food crops on allotments or as part of a business, newly planted trees, hedges and shrubs (within 3 years of planting) that can’t reasonably be hand-watered, health and safety needs, animal welfare (pets, livestock, fish), hospitals and prisons, and customers who only receive wastewater services from Thames Water rather than their water supply. Business exemptions, including for vehicles used commercially, have their own detailed rules — Thames Water’s FAQ page covers taxis, private hire vehicles, gardeners and window cleaners specifically, since the answer depends on exactly how the hosepipe is being used.

Is this just a Thames Water problem?

No. This is part of a much wider squeeze across southern and eastern England.

Bans are already in force for Southern Water customers in Hampshire and the Isle of Wight, Cambridge Water customers, Affinity Water customers across Bedfordshire, Berkshire, Buckinghamshire, Essex, Hertfordshire, Surrey and parts of London, and Anglian Water customers in the east. South East Water added 2.4 million more customers to its own restrictions this week.

The Environment Agency says large parts of southern, central and eastern England are now edging closer to official drought status. Six reservoirs are rated “notably low,” and one, Blagdon in Somerset, is “exceptionally low.” Only 13% of rivers are at normal levels for the time of year.

In other words, Thames Water isn’t an outlier. It’s the latest and largest domino to fall in a summer that has repeatedly tested the country’s water system.

How long will the ban last?

Thames Water hasn’t set an end date. The company says it will keep reviewing conditions and lift the restrictions as soon as it’s safe to do so, which in practice means waiting for sustained rainfall to refill rivers and reservoirs.

That uncertainty is itself part of the story. It comes as Britain’s new government under Prime Minister Andy Burnham faces early pressure on domestic issues far beyond the economy, from tax devolution for regional mayors to, now, ageing water infrastructure straining under climate extremes.

Frequently Asked Questions

When did the Thames Water hosepipe ban start?

The ban came into force at 00:01 on Thursday, 23 July 2026, though Thames Water asked customers to start following it a little earlier.

Am I exempt if I’m elderly or can’t lift a watering can?

Age alone doesn’t automatically exempt you, but a physical impairment or restricted hand movement does qualify you for Thames Water’s Priority Services Register — which does. Contact Thames Water to register; they’ll write to confirm your exemption.

Can I water food crops or my allotment with a hosepipe?

Yes. Watering food crops, whether on an allotment or as part of a business, is one of the listed exemptions to the ban.

What’s the fine for breaking the hosepipe ban?

Up to £1,000, imposed by a court under Section 76 of the Water Industry Act 1991.

When will the hosepipe ban end?

Thames Water hasn’t given an end date. Restrictions will be lifted once water levels recover, which depends on sustained rainfall refilling rivers and reservoirs.

Do Blue Badge holders need to register separately?

No. Blue Badge holders are automatically exempt and don’t need to also register for the Priority Services Register, though registering can still be useful for other support.

Can I use a hosepipe to water newly planted trees or hedges?

Yes, if they were planted within the last 3 years and can’t reasonably be watered by hand instead.

The bottom line

Thames Water’s hosepipe ban isn’t a one-off overreaction. It’s the predictable outcome of a dry spring, a record-hot June, and a supply network already running close to its limits. If you have a medical or mobility reason you can’t easily switch to a watering can, registering for the Priority Services Register is worth doing now rather than waiting. Whether the ban itself lifts in weeks or drags into autumn depends entirely on how much rain falls next — something no water company can control.
