A water butt collects rainwater from your roof, giving you a free supply for watering plants and other jobs around the garden. The average roof collects around 85,000 litres of rain a year — enough to fill around 340 water butts. Why let it go down the drain?

Water-efficient washing machines and dishwashers use less water every cycle. And because they tend to be more energy efficient too, you'll save on your energy bills at the same time. When it's time to replace yours, choose the highest water and energy efficiency rating you can.

A leaking toilet can waste hundreds of litres of water every day without you even noticing. Place a detection strip at the back of the pan, just below the rim. If it changes colour, water's trickling down when it shouldn't. Don’t have any strips? A piece of toilet paper does the job too.

Four minutes. That's the Champion target. But any time knocked off your usual is a win for us all. A shower timer helps keep the whole household on track, making shorter showers easier to stick to. Small kit. Big impact.

Watering Can Convert's favourite bit of kit. Swapping a hosepipe for a watering can gives you more control over how much water you use, making every drop count. It also means you can water where it's needed most, waste less water and keep your garden looking its best.

Aerators screw onto most taps and showerheads in seconds. These simple devices mix air into the water flow, so you use less water without noticing the difference. Fitting them to all your taps could save around 15,000 litres a year. That’s around 180 baths.

Simple, cheap and seriously useful. Washing a car or bike with a couple of buckets instead of a hose can save around 8,000 litres a year. That’s about 4,700 kettles. You can also use a bucket to collect rainwater or save excess shower water for later use.

A simple upgrade that puts you in control. A hose gun means water only flows when you're actually using it. No running hose and no wasted water while you move between plants or rinse the car.

Sink Plug Pro's favourites. Filling the sink rather than running the tap while you wash up could save up to 8,500 litres of water a year — that's around 850 sinks full. Better still, use a washing-up bowl and reuse the leftover water in the garden.

Toilets account for nearly a third of household water use. A dual-flush toilet gives you the choice of a half flush for liquid waste and a full flush when you need it, reducing water use every day. Well worth considering if you're renovating or replacing your bathroom.

Not ready to replace your toilet? A save-a-flush device sits inside your cistern and reduces the amount of water used with every flush. It takes just two minutes to fit and starts saving water straight away.

Kit out your garden for a hotter, drier future. Think succulents, ornamental grasses and Mediterranean herbs and shrubs. They need less watering, cope better in dry weather and still keep your garden looking its best.
