Hosepipe Ban: The 28-Day New Turf Exemption Explained
Published:
Yes. Newly laid turf and newly sown grass seed can be watered with a hosepipe for the first 28 days, even during a hosepipe ban.
But the exemption is narrower than it sounds. For most water companies it applies only to turf laid before the ban started. Some attach conditions, such as watering outside peak hours or asking permission first. It is not a general licence to water your lawn: an established lawn gets no exemption anywhere in the UK.
The 28-day rule is real, and it is written into the exemption lists that water companies publish alongside their Temporary Use Ban notices. It exists because turf that cannot root simply dies, which causes real hardship for households and landscape contractors while saving very little water. The Turfgrass Growers Association negotiated it with the water companies, alongside codes of practice agreed with the Horticultural Trades Association and the Association of Professional Landscapers.
What almost every article about it gets wrong is the caveats. The wording differs between companies in ways that change whether you are allowed to water at all. Below is what each company actually publishes.

| Company | Exemption wording | Conditions | Source |
|---|---|---|---|
| South East Water | New turf laid BEFORE the start of the ban, in domestic gardens, may be watered by hosepipe for 28 days (four weeks) after planting or laying to help it establish. | Water outside the daily peak hours of 8am to 10am and 5pm to 9pm. You must be able to evidence the date the works were completed if asked. Watering beyond 28 days, or failing to evidence the date, is a breach. | Kent hosepipe ban FAQs |
| Cambridge Water | Newly laid turf may be watered by hosepipe for 28 days. Newly sown grass seed may be watered by hosepipe for its first 28 days, after which a watering can is required. Gardeners and landscapers may water newly laid or newly sown lawns and new planting by hose for the first 28 days. | Cambridge Water asks that anyone using the exemption respects the spirit of the restrictions and uses water wisely. Trees, whips, saplings and hedging planted in the last three years may also be hosed where they cannot be hand watered. | Temporary hosepipe ban FAQs |
| Southern Water | Newly laid turf may be watered by hosepipe for 28 days, but you must request permission from Southern Water first. | The permission step is the stricter condition here. Most companies grant the exemption automatically; Southern Water asks you to apply for it. Do not assume it applies until you have asked. | Hosepipe ban exemptions |
| Anglian Water | New lawns laid before the Temporary Use Ban may be watered for up to four weeks (28 days) after laying, where watering by can is not a practical option. | Two conditions stack: the turf must pre-date the ban, and a watering can must be impractical. Anglian also restricts dripper hoses and automatic irrigation connected to the mains, so a soaker hose is not an alternative route. | Restrictions and exceptions |
| Yorkshire Water | Under its 2025 ban, Yorkshire Water allowed newly laid turf to be watered by hosepipe until it was 28 days old. | No ban is in force in Yorkshire in 2026, so no exemption is needed. This wording is the standing position that would apply if Yorkshire Water declared a TUB. | Is there a hosepipe ban? |
| Thames Water | No formal TUB is in force, so no exemption currently applies. Thames Water is urging customers to limit hosepipe use voluntarily. | If Thames Water declares a TUB, check its notice: the company publishes its exemption list alongside the legal notice rather than in advance. | Hosepipe ban FAQs |
Companies not listed here have no published turf wording, or no ban in force. If your supplier is not above, check its own Temporary Use Ban notice rather than assuming the 28-day rule applies. Every company page in our UK hosepipe ban hub links to the notice.
The Three Caveats That Matter
1. The turf usually has to pre-date the ban. South East Water's wording is explicit: new turf laid before the start of the ban, for 28 days after planting or laying. Anglian Water says new lawns laid before the Temporary Use Ban. If you buy turf on the weekend a ban starts and lay it on the Monday, those two companies do not cover you. This is the single most common error in coverage of the rule.
2. Some companies attach conditions. South East Water requires you to water outside the daily peak hours of 8am to 10am and 5pm to 9pm, and to be able to evidence the date the works were completed if asked. Southern Water requires you to request permission before you rely on the exemption at all. Anglian Water only permits it where watering by can is not a practical option, and separately restricts dripper hoses and automatic irrigation, so a soaker hose is not a workaround.
3. It is not a lawn-watering loophole. An established lawn gets no exemption from any UK water company. The 28-day window exists so new turf can root. Water companies grant it on the understanding that people will, in Cambridge Water's phrase, respect the spirit of the restrictions. Using it as cover for keeping a mature lawn green is a breach, and the £1,000 maximum fine applies. See our guide to hosepipe ban fines for how enforcement actually works.
How to Water New Turf Efficiently Within the Exemption
New turf needs water to knit its roots into the soil below. The goal in the first 28 days is to keep the soil beneath the turf moist, not to keep the grass blades wet. Lift a corner: if the soil underneath is damp to a finger's depth, you do not need to water.
- Days 1 to 7: water daily, deeply enough to wet the soil below the turf, not just the turf itself. Roughly 10 to 15 litres per square metre on laying day, then enough to keep the base damp.
- Days 8 to 21: taper to every other day. This is when roots chase moisture downwards. Watering less often but more deeply drives deeper rooting, which is exactly what you want before the exemption expires.
- Days 22 to 28: every third day. By now the turf should resist a gentle tug. If it lifts freely, it has not rooted, and you have a week left.
- Time of day: early morning. Where South East Water's peak-hour condition applies, that means before 8am. Early watering loses least to evaporation and lets blades dry before evening, which limits fungal disease.
After day 28. The hosepipe exemption ends, but the turf is not necessarily established. A watering can or bucket is legal at any time under any UK TUB, and remains so. A 9-litre can carries enough for roughly one square metre. For a small new lawn this is tedious but workable. For anything larger than about 30 square metres it is a serious commitment, which is the honest reason to think hard before laying turf under a ban. Collected rainwater from a water butt is entirely unrestricted and can go through a hosepipe attached to the butt, since the restriction is on mains water through a hosepipe.
Should You Delay Laying Turf Until the Ban Lifts?
In most cases, yes. Three reasons, in order of weight:
- The exemption may not cover you. If your supplier is South East Water or Anglian Water, turf laid after the ban started falls outside the published wording. You would be laying turf you are not permitted to hose.
- Establishing turf in a heatwave is hard even with water. Bans arrive during the conditions that are worst for new turf: high temperatures, high evaporation, dry soil below. Turf laid in October roots into warm, moist soil with autumn rain doing most of the work, and needs almost no intervention.
- The 28 days may not be enough. Turf laid in peak summer often needs longer than four weeks to root properly. The exemption is a fixed window, not a measure of when your lawn is ready.
Autumn (September to early November) is the best time to lay turf in the UK, and spring is second. If you have already bought the turf and it is on a pallet, you do not have the option to wait: unlaid turf deteriorates within days. Lay it, water it within your company's exemption, and check the wording first.
If you are trying to keep an existing lawn alive rather than establish a new one, that is a different problem with a different answer. See keeping your lawn alive during a hosepipe ban and what you can still do under a hosepipe ban.
Frequently Asked Questions
Can I water new turf during a hosepipe ban?
Usually yes, for the first 28 days after laying, but only if the turf was laid before the ban started, and only under your own water company's conditions. South East Water and Anglian Water both restrict the exemption to turf laid before the ban began. Southern Water requires you to request permission first. Cambridge Water extends the exemption to newly sown grass seed as well as turf. Check your own company's notice before you rely on it.
Does the 28-day exemption apply to grass seed as well as turf?
It depends on the company. Cambridge Water explicitly covers newly sown grass seed for its first 28 days, after which you must switch to a watering can. Anglian Water's wording refers to new lawns laid, which its drought plan reads as covering sown lawns. Several companies mention turf only. If your company's notice does not name grass seed, do not assume it is covered.
What if I lay turf after the hosepipe ban has already started?
For most companies the exemption does not help you. South East Water's wording covers new turf laid before the start of the ban, and Anglian Water's covers new lawns laid before the Temporary Use Ban. Turf laid after the ban began falls outside those words. Cambridge Water's published wording does not carry the before-the-ban condition, but it does ask that you respect the spirit of the restrictions. If you have not laid the turf yet, the honest advice is to wait.
Does the 28 days restart if I re-turf or patch a lawn?
No company publishes a rule that lets the clock restart by re-laying. The 28 days runs from the date the turf was laid or the seed was sown, and South East Water can ask you to evidence that date. Patching a failed area with fresh turf starts a 28-day window for that new turf, not for the whole lawn. Deliberately re-turfing to reset the clock would be a breach of the conditions of the ban.
Will I be fined for watering new turf during a hosepipe ban?
Not if you are inside your company's exemption and can show it. The maximum fine for breaching a TUB is £1,000 per violation under Section 76 of the Water Industry Act 1991, and companies almost always warn before prosecuting. The risk is watering outside the exemption: past 28 days, outside permitted hours where those apply, without the permission Southern Water requires, or on an established lawn.
Does an established lawn get any exemption?
No. There is no exemption anywhere in the UK for watering an established lawn with a hosepipe during a Temporary Use Ban. The 28-day rule exists so that newly laid turf and newly sown seed can root before they die, not so that lawns can be kept green. An established lawn will brown off and recover with autumn rain. You can water it with a can or bucket at any time.
Who negotiated the 28-day exemption?
The Turfgrass Growers Association worked with water companies to have newly laid turf included in their hosepipe ban exemption lists, alongside codes of practice agreed with the Horticultural Trades Association and the Association of Professional Landscapers. The rationale is that turf which cannot root simply dies, causing hardship for households, landscape contractors and growers, while the water saved by refusing the exemption is small.
