Rising Water Bills From April 2026: Three Simple DIY Fixes That Could Save Households Hundreds

EVESHAM, U.K. - EntSun -- Households in England and Wales are set to see water bills rise again from April 2026, with average annual costs increasing by £33 to around £639. With water costing approximately 0.35 pence per litre, everyday usage can quickly add up, meaning many households may be unknowingly overspending through inefficient fixtures.

However, simple DIY changes can make a noticeable difference. Many water-saving solutions are inexpensive, easy to install, and can be fitted without the need for a plumber or specialist tools, helping households reduce both water usage and monthly bills.

1. Swap to a water-efficient shower head
Water-efficient shower heads can reduce usage from around 10–15 litres per minute to as little as 6 litres, saving up to 90 litres during a typical 10-minute shower.

Over a year, this could save up to 32,000 litres of water per person. At a cost of 0.35p per litre, this equates to around £115 annually on water bills alone, with additional savings from reduced hot water usage.

They are inexpensive, easy to install, and can be fitted in minutes by attaching to an existing shower hose, making them a practical long-term solution for reducing household water consumption.

2. Install tap aerators
Tap aerators reduce water flow by mixing air with the stream, maintaining pressure while lowering overall usage. Some models can cut flow from around 15 litres per minute to as little as 6 litres.

This can save up to 15,000 litres of water per year. Based on a cost of 0.35p per litre, that's around £50 annually, simply by reducing excess water flow during everyday tasks.

They are low cost, widely available, and can be fitted to existing taps in seconds, making them one of the easiest ways to improve water efficiency.

3. Upgrade to a dual-flush toilet
Older toilets with single flush systems can use up to 13 litres of water per flush, significantly more than modern dual-flush alternatives.

Reducing just five flushes per day by six litres could save around 11,000 litres of water per year. At 0.35p per litre, this equates to approximately £38 annually in water costs, with higher savings likely in larger households.

For those confident with DIY, upgrading to a dual-flush system can be a manageable task, with many modern designs created for straightforward installation.

With water charged per litre, even small reductions in daily usage can lead to meaningful savings over time. As bills continue to rise, these small changes can help households better manage costs while using water more efficiently. (https://www.plumbworld.co.uk/blog/how-to-save-water-at-home)
