Small changes can make a big difference to your bills and the planet
Taps & sinks

Taps & sinks

Dripping taps

A dripping tap can waste up to 90 litres per week. Replace a tap’s washer as soon as you notice a drip.

Tap aerators

Tap aerators are a relatively low-cost way to reduce the flow of your taps while maintaining their effectiveness. You can choose taps with aerators fitted, or retro-fit them to existing taps.

Self-closing taps

Even with the best will in the world, it’s easy to leave a tap running by mistake. A running tap can waste as much as 6 litres every minute. Fit self-closing taps to prevent this from happening.

Water basins

Using a basin for washing up significantly reduces the amount of water used. Make sure a basin is provided at each sink where dishes are washed.

Ill-fitting plugs

Providing plugs will encourage staff to fill a sink rather than using continuously running water. Ill-fitting plugs will waste water if they do. Make sure that each sink has a well-fitting plug.

Stickers or posters

Friendly, clear and effective signage can help encourage good behaviours in your staff. Try to keep them positive and encouraging.

Toilets & urinals

Toilets & urinals

Dual-flush mechanisms

A dual-flush toilet gives staff the option to half the water used in flushing the toilet. When there’s no need to use a full flush, they don’t have to. This can significantly reduce the water used in essential and unavoidable toilet flushing.

Hippos or cistern displacement devices

Installing dual-flush toilets can be a significant financial outlay if you don’t have them already. If you can’t afford to install dual-flush, consider a cistern displacement device, sometimes called a Hippo. Hippos reduce the volume of water that the cistern can hold, forcing staff to use less each flush.

Urinal controls

Urinals which constantly leak or flush too regularly can waste a huge volume of water and they’re a common source of waste that we find when auditing businesses. Check for unwanted leaks or over-regular flushing, and ensure that the latest control mechanisms are fitted. You could also consider installing waterless urinals.



Leaking or dripping units

As with taps and sinks, dripping showers can be a slow but steady source of waste which builds up significantly over time. Make sure to repair dripping showers as soon as you notice them.

Push-button controls

Push-button controls ensure that showers shut off after a short period of time, minimising the chances of them being left on by accident.

Low-flow heads

Low flow heads can be a relatively cheap way of improving the efficiency of your showers, maintaining their power and effectiveness while using significantly less water.

Shower timers

A shower timer can be a cost-effective solution to remind staff to keep their shower time to a minimum. Less time in the shower = less water wasted.

Stickers or posters

Again, stickers, posters and signage around the shower area can be particularly helpful in encouraging staff to be considerate with their showering.




Investing in an eco-boiler that heats the water as you need it is a great way to save time and money. It prevents your staff from over-boiling the kettle, saving on water and energy.

Water coolers

Waiting for the tap to run cold for a glass of water can waste 10 litres of water every day. Providing water coolers which deliver instant cold water will reduce this unwanted wastage.

Dish & glass washers

Ensure that you’ve installed the most energy and water-efficient models you can afford, and that you use the Eco setting wherever possible.

Dripping taps & tap aerators

As with toilets and bathrooms, kitchen taps can suffer from drips and leaks. And like other taps, they benefit from aerators to reduce water flow.

General plumbing

General plumbing

Water pressure

High water pressure can cause pinhole leaks in your water system, which can lead to major leaks and wider issues including serious property damage. Try to ensure your water pressure is at the lowest level it can be for your needs.

Visible pipework

Plumbing pipework is often concealed, but if you have areas of visible pipework around your premises, check them carefully for visible signs of leakage.

Grounds & gardens

Grounds & gardens


Go native and natural

When considering business landscaping, choose as many existing trees and shrubs as possible. Established plants usually require less water and maintenance. Try to choose plants native to the UK too. Once established, they’ll require very little to no water beyond normal rainfall.

Avoid lawns if you can

It’s lovely to enjoy lunch outside on a warm day, but maintaining lawns can be water-intensive and expensive. Do you need to lay turf or are there alternatives?

Increase drainage

It might seem counter-intuitive, but consider working sand through your soil, to keep it porous and allow water to drain more effectively. This will encourage plants to root deeper into the ground, making them more resilient to drought.

Watering & lawn care

Water your lawns wisely

It’s better to water your lawns heavily once a week, rather than lightly every day. This encourages the grass to root further down, delivering increased flood and drought-resistance. Water your lawns first thing in the morning for maximum impact.

Sprinklers use up to 1,000 litres per hour

That’s more than a family of four use in a day. They’re best avoided, but if you can’t, try to make sure you’re not over-sprinkling. Catch water in a measuring jug to calculate sprinkler output. 3/4 to 1 inch of water is enough to apply each time you irrigate.

Brown is the new black!

Consider letting those lawns go brown in the summer. And remember, if you look after them during the winter, they’ll survive the tougher times too.

Rainwater harvesting

Rainwater from roofs or large paved areas (e.g. car parks) can be recycled and used for toilet flushing, vehicle washing or watering plants.

Greywater recycling

Waste water from washroom basins and showers can be recycled and used for flushing toilets or watering grounds and gardens.

Your processes

Your processes

Consider all the ways your business uses water

We’ve covered some of the main areas, but now you’ve walked round those, are there any others that we’ve missed? Are there any specific to your business?

Are they essential?

Can you identify any non-essential uses of water within your business? Consider also the frequency that you carry out these processes. Is it essential that you do them as often as you do?

Are they efficient?

Particularly for any specialist areas that your business uses water, consider how efficient your processes are. When was the last time you researched the latest water efficiency tactics and techniques in your industry? Industry press and online communities are a great resource of specialist knowledge in your area. Do some research into the latest equipment and practices and see how you compare.
