1. Fix leaking or dripping taps - Save up to £398.67

Fixing a dripping tap is one of the simplest yet most effective changes you can make. reports that a dripping tap wastes at least 5,500 litres of water annually, equating to a wastage of £22.12 per tap.

If it progresses to a trickle, a tap can waste up to 175,000 litres yearly, costing around £398.67, according to a study from Tap Warehouse. A failed washer is the most common cause of a dripping tap and replacing it can be done in five simple steps:.

  • Cover the drain to prevent anything falling down it.
  • Turn off the water.
  • Remove the top and valve.
  • Replace the washer.
  • Replace the tap.

2. Energy-efficient dishwashers - Save up to £78.66

Dishwashers, particularly in homes where baking or entertaining is a regular occurrence, can be significant consumers of water and energy. However, making the switch to an energy-efficient dishwasher can significantly cut down on this usage.

Compared to a standard model, these dishwashers use approximately 30% less water, translating to an annual saving of £40.16, and 12% less energy, equating to around £38.50, when used daily.

Choice, a consumer advocacy group, states that hand washing dishes can consume up to 100 litres of water. In contrast, older dishwashers, although not as efficient as current models, only use about half the water of washing by hand, with newer models using as little as 8.4 litres per cycle.

For households without a dishwasher, it may be worth considering investing in one, even if it's an older pre-owned model, due to the potential savings. For those who already own a dishwasher, it's advisable to wash full loads only and utilise the water-saving setting if available.

3. Low-water-use toilets - Save £56.95 annually per person

Toilets are another area where significant water savings can be made in the home. Traditional toilets can use up to 14 litres of water per flush, but modern low-water-use toilets can reduce this by around 80%.

This could result in savings of up to 25,000 litres, or around £56.95, of water per person each year. Dual-flush toilets, for instance, provide flush options for varying amounts of waste, enabling users to opt for a lighter flush when suitable. Fitting these toilets can decrease your water consumption and cut down your overall water bill while ensuring the same level of hygiene and comfort for family and friends.

For those on extremely tight budgets, fitting a water displacement device could be a feasible option. These devices effectively cause the cistern to underfill, using slightly less water per flush.

4. Rainwater harvesting systems - Average savings of £306

A rainwater harvesting system enables households to gather and store rainwater for non-drinking uses, such as watering plants, flushing toilets, and cleaning. This reduces dependence on mains water and can result in substantial savings, especially in areas with high rainfall.

A brilliant initial step in rainwater harvesting is setting up a water butt, which can be bought for as little as £34 on Amazon. This allows you to trial the reclaimed water process without the expenses associated with a full system installation.

More comprehensive harvesting solutions can help save 40-50% off the average household water bill, which equates to up to £306 for a family of four, based on Southern Water's 2023 rates. Given that the average home uses 30% of its water to flush the toilet, businesses could see significant savings by utilising rainwater.

5. Leak detection systems - Potential to save £1,000s

It's estimated that undetected leaks result in three billion litres of water being wasted every day in England alone, as per Global Citizen. The European Commission suggests that smart leak detection technologies could save up to 50% of public water supplies.

Installing these systems can help identify and repair leaks promptly, with some even automatically shutting off the water supply.

In addition, insurers often encourage the use of leak detection devices, and homes may be eligible for further discounts if they have one installed. For homeowners who cannot commit to a leak detection method, a good starting point is to manually inspect visible plumbing for leaks and fix them promptly. This can help avoid any unexpected repair costs from water damage.

According to UKLeakDetection, repairing a leak in kitchen walls and tiles can cost up to £10,000, and properly drying concrete floors can cost as much as £1,000.

6. Aerators for taps - Up to £110.17 per person

Installing aerators on taps can reduce water flow while maintaining the same pressure. These devices mix air with water, making the flow feel stronger while using less water.

They are easy to install and can be fitted to most standard taps.

To give you a sense of scale, it's estimated that an office worker uses 75 litres of water each day, and with many of us now working from home, we're likely using even more. However, homeowners have numerous opportunities to save.

According to online aggregator platform, taps fitted with aerators can use up to 50% less water, leading to savings of up to £110.17 per person annually.

A spokesperson from Clearsight Energy said: "By implementing these simple and effective changes, homeowners can drastically reduce their water consumption and save on monthly costs. Tap aerators and energy-efficient dishwashers are just a couple of the many ways homes can be more water-wise without compromising service quality."

"It's important for homeowners to be aware of the potential water savings they can generate without any upfront cost, such as a simple check of visible plumbing for obvious leaks and running dishwashers in water-saving modes with full loads."
