Don't leave the tap running while brushing your teeth - turn it off when you don't need water

Install a tap aerator, which mixes the water with air so you use less but without losing water pressure

Add a shower limiter, so you'll use less water per shower

Use a shower timer, so you spend less time in the shower

Descale shower heads regularly, to avoid limescale blockages

Check for any leaks or drips and fix any you find

Save water from cooking pasta and use it to water plants when cool

Water lawns at dusk or dawn, or use an automatic dusk/dawn timer
