Kent Hosepipe Ban: A Garden Designer's Guide to What to Save First

What the Ban Actually Covers

The Kent hosepipe ban is South East Water's Temporary Use Ban for its Kent supply area, in force from 00:01 on Friday 3 July 2026, affecting around 850,000 customers. It doesn't apply to South East Water's Sussex, Surrey or Berkshire areas, and it isn't the same ban Southern Water has introduced for Hampshire and the Isle of Wight. If you garden in Kent and you're supplied by South East Water, this one is yours, caused by a sustained heatwave draining reservoirs faster than the works can refill them.

You can't use a hosepipe to water the garden, wash the car, clean the patio, walls or windows, fill a pool or hot tub, wash a boat, or run a fountain. Break it and you risk a fine of up to £1,000 under the Water Industry Act 1991. Exemptions exist for Priority Services Register customers unable to make reasonable adjustments, for animal welfare, and for genuine business needs.

The Exemption Most People Miss

Here's the fact that changes the conversation: a hosepipe connected to a water butt, or any other stored or recycled water supply, isn't covered by the ban. That's not a loophole; it's written into the restrictions themselves. If the water didn't come through your meter, you're free to run it through a hose exactly as any other day.

For anyone with a decent-sized butt or a rainwater harvesting system, that's a genuine lifeline. It won't replace mains watering for a whole garden after weeks without rain, but it means water you've already collected doesn't have to be rationed out with a jug. Watering cans are unaffected regardless of source too.

Triage: What to Save First

This is where decades of watching gardens live and die through dry summers earns its keep. You can't water everything with a can and a butt, so the order matters.

New Planting First

Anything planted this year, or even last autumn, comes first. It hasn't had time to establish a root system reaching beyond its original planting hole, so it has no reserves and nowhere else to find moisture. A young shrub in the ground eight weeks can die in a week of hot, dry weather that an established one wouldn't even notice. If you've had new planting done this year, that's where your water goes first, every time.

Trees and Shrubs Next

After new planting, it's trees and shrubs, particularly anything that's taken years to reach its current size. These represent real investment, both financial and in time you can't get back, and they're hardest to replace. A mature shrub lost to this drought isn't back next spring; it's gone, and whatever replaces it starts from nothing. Established trees have deeper roots than most people credit them with, so keep a closer eye on anything young or recently pruned.

Perennials Can Sulk

Perennials come next, and this is where I'd ask people to relax a little. A herbaceous perennial that looks wretched by August, crisped and collapsed, is very often not dead. It's doing what perennials do: pulling back to protect the rootstock and waiting for better conditions. Give it a deep soak when you can, and don't panic if it looks worse before it looks better. Most recover fully once the weather breaks.

Lawns Last, Always

Lawns come dead last, and this is the bit that surprises people most. A brown lawn is not a dead lawn. Grass is remarkably good at going dormant in a drought and greening back up within a couple of weeks of proper rain; it's one of the most resilient things in any garden. Pouring your limited water and time into a lawn while a border of new perennials goes thirsty is exactly backwards. Let the lawn go brown; it'll forgive you completely, and everything else needs your attention more.

How to Water So It Counts

Watering cans aren't restricted, so how you use them matters. Water at the base, not over the leaves; wetting foliage does little for the roots and loses water to evaporation before it reaches the soil. Water early morning or evening, when less is lost to the sun.

The biggest mistake I see is a little water, often, rather than a proper soak occasionally. Frequent light watering trains roots to stay near the surface, making a plant more vulnerable, not less. A thorough soak once or twice a week beats a daily splash that never gets past the top inch of soil.

Mulch: Cheap Insurance

If you do nothing else this summer, mulch. A layer of bark, compost or well-rotted manure, two to three inches deep and clear of the stems, slows evaporation from the soil dramatically. It's cheap, quick, and works around the clock without you lifting a finger.

Grey Water: What's Worth Reusing

Cooled washing-up water and old bathwater are fine to tip onto borders, a useful supplement while the ban is on. Avoid anything that's touched bleach, dishwasher salt or strong detergents, which build up in the soil and do more harm than the drought would have.

Containers and Pots

Pots are usually first to suffer; there's so little soil to hold any reserve of moisture. Grouping pots together helps enormously, creating a more humid microclimate and reducing exposure to drying wind and sun. Move what you can into shade during the hottest part of the day, and check daily; a pot fine in the morning can be critically dry by evening.

Conclusion

None of this makes a hosepipe ban comfortable, but it does make it manageable. Know what the ban restricts, use the water butt exemption if you have one, and get your priorities right: new planting first, then trees and shrubs, then perennials, lawns dead last. A brown lawn in August is nothing to worry about. A shrub you planted three years ago is.

Summers like this one are becoming a regular feature of Kent gardening, and it's changed how I design gardens from the outset, choosing plants that don't need rescuing every July. That's worth exploring another day.
