South East Drought 2026: What the Hosepipe Ban Means for Your Home's Plumbing

2026 has been one of the driest years on record for England, and South East Water has extended its Temporary Use Ban (hosepipe ban) into Sussex, Surrey, Hampshire and Berkshire — the first time restrictions have applied in Surrey, Hampshire and Berkshire in 14 years. With reservoirs like Arlington in Sussex running well below average after one of the driest starts to the year on record, water companies across the region are asking homeowners to cut back wherever they can.

As local plumbers working across all of these counties, we're seeing first-hand how much of a difference small plumbing issues make to household water use during a drought. Here's what's actually happening, and what you can do about it.

What's Changed in the South East

Temporary Use Bans restrict things like using a hosepipe to water gardens, wash cars, or fill paddling pools and ponds. They're issued by water companies under the Water Industry Act when reservoir and groundwater levels fall low enough to threaten supply. If you're in a South East Water, Southern Water or Thames Water area, it's worth checking your supplier's website directly, as restrictions can change through the season.

What doesn't always make the headlines is that indoor water use matters just as much as garden watering — and it's often where the easiest savings are hiding.

Why Fixing Leaks Matters More Than Ever

A single dripping tap can waste over 5,000 litres of water a year. A running toilet — often silent, caused by a worn flush valve — can waste far more than that without you ever noticing a puddle. During a drought, these hidden losses go from "annoying" to genuinely significant at a regional level.

We've written before about how to spot a hidden water leak before it costs you — an unexplained rise in your water bill, a water meter that keeps ticking over with everything switched off, or damp patches that won't go away are all worth checking out. If you're not sure, our leak detection service uses non-invasive equipment to find the source without digging up your home.

The Mandatory Water Efficiency Label — What's Changing in 2026

Separately from the drought, 2026 also sees the rollout of the Mandatory Water Efficiency Label (MWELS), which requires taps, showers, toilets and other water-using products to carry a clear A–F efficiency rating at the point of sale — similar to the energy labels already familiar on appliances. For homeowners planning a bathroom refit or simply replacing an old toilet or showerhead, this makes it much easier to compare water use before you buy.

If you're due a bathroom update, pairing it with water-efficient fittings is a practical way to cut consumption long-term rather than just during a drought. Our bathroom installation service can advise on efficient fixtures as part of any refit.

5 Practical Ways to Cut Water Use at Home

• Fix dripping taps and worn washers — often a five-minute job that stops continuous waste.
• Check for a silently running toilet — add a little food colouring to the cistern; if it appears in the bowl without flushing, you have a leak.
• Fit aerators or low-flow showerheads — these cut water use noticeably without a noticeable drop in pressure.
• Use a water butt instead of a hosepipe where restrictions apply, for anything that isn't covered by the ban.
• Monitor your water meter — a quick before-and-after-bed check with everything off is the simplest leak test there is.
