Consumer experts at Which? claim people living in areas currently under a hosepipe ban could get around the rules 'legally' by using one thing in their gardens. It might involve showering, bathing or washing up with one extra item.

People can find out whether they are currently in an area subject to a hosepipe ban here. Speaking on Instagram, the team at Which? said: "We have another hosepipe ban, but your beloved plants still need water. The solution is called grey water."

What is grey water?

Which? claims that 'grey water' is broken down into two types. 'Light grey' water is wastewater from washing your hands or taking a bath or shower, while 'dark grey' water is soapy dish water.

The easiest way to collect it is by using a washing-up bowl in your sink or shower. This will catch any runoff water, which could be used for watering plants or lawns during a ban period.

As this 'grey water' is essentially recycled domestic wastewater that does not place extra demand on public water treatment supplies, water companies will have no issue with this. But, it should be used quickly and not stored for too long, as stagnant water can become a breeding ground for bacteria. It is also likely to attract bugs and other pests wanting to drink.

It is claimed that most 'grey water' is safe to reuse for other purposes around the home. Most body soaps and dish detergents are mild enough not to cause issues with grass and plants, but some must go down the drain.

Which? added: "Avoid water with a softener in it, especially if it's sodium-based. This can damage the soil structure and potentially harm plants and the ecosystem."

The team also said that people should not reuse water that has been mixed with "strong cleaning chemicals" such as bleach or petroleum-based products, as these can harm their plants.

While flower and grass lawns can benefit from recycled 'grey water', people who grow fruit or vegetable patches might want to think twice because of the risk of contamination that can occur after they are eaten.

Which? suggests: "Alternate between grey water and tap water so any salts or contaminants added to the soil are washed through and don't build up. This is particularly important for plants in pots and baskets as they contain relatively small amounts of compost."

Who enforces a hosepipe ban?

A hosepipe ban (legally called a Temporary Use Ban) is a rule set by water companies to stop people from using garden hoses and sprinklers. These bans happen during dry weather when water supplies run low.

Hosepipe bans are needed to protect public water supplies, safeguard essential needs like drinking and sanitation, and prevent environmental damage to low rivers and reservoirs during dry weather and heatwaves. Things that are banned include:

  • Water gardens: You cannot use a hose to water plants, lawns, or flowers
  • Wash vehicles: You cannot use a hose to clean cars, vans, or boats
  • Clean outdoor areas: You cannot use a hose on paths, patios, walls, or windows
  • Fill pools: You cannot use a hose to fill swimming pools, paddling pools, or hot tubs

Hosepipe bans are enforced by water companies and can carry a fine of up to £1,000 if homes break the rules. Water company staff monitor compliance, and members of the public can report suspected rulebreakers directly to their respective regional water provider.
