How to save water—and lower a metered bill

Focus on hot water first

Shorter showers can reduce both the water bill and the energy needed to heat water. A modern shower may use roughly 8–12 litres a minute, while some power showers use more.

• Cut two minutes from each shower.
• Fit an efficient shower head if it works with your system.
• Fix dripping hot taps.
• Use a bowl rather than running a hot tap continuously.

Run full appliance loads

Dishwashers and washing machines use a similar volume whether partly or fully loaded. Eco settings are designed to trade time for lower energy and water use.

• Wait for a full load.
• Use eco mode for normally soiled items.
• Avoid pre-rinsing dishes under a running tap.
• Replace appliances for efficiency at end of life—not solely to save water.

Stop silent waste

A constantly trickling toilet can waste a surprising amount without making much noise. Add food colouring to the cistern and wait without flushing; colour entering the bowl can indicate a faulty seal.

Use rain in the garden

A water butt makes rain available for pots and beds. Water early or late, mulch soil and direct water to roots. A hose can use hundreds of litres an hour, so garden use is worth managing carefully.
