Thousands of pounds cut from weekly water costs in at-scale 2026 action

Thousands of locations are benefiting from taking-up small actions that save water and find inefficiencies that add to running costs.

It’s building on work that saw 3,609 water-saving visits delivered at businesses, care homes, sports clubs and council sites in collaborative at-scale activity.

“It’s been brilliant to increase positive results and benefits for these sites."

"And we're working with sites involved in this project, helping them to take more proactive steps around identifying further areas for reducing water waste.”

Scott MacIndeor, who leads the technical water efficiencies team at Water Plus

The Challenge

Unlocking Water-Saving opportunities across sites

Many sites keen to save water aren’t sure where to start – and where opportunities may be.

With water scarcity risks in the UK, without collective action, the approach combined awareness and education, with small changes to reduce water use and costs.

Finding smarter ways to use water can not only lower costs it can also cut carbon emissions. And where less hot water’s needed it can lower energy costs too.

Luke Brewer-Nevitt, Water efficiency Delivery Manager at United Utilities, added: “Finding more ways to save water not only lowers running costs it also reduces pressure on supplies and the environment, helping keeping water flowing for everyone.”

The solution

Turning insight into action

Insight and data were used to identify sites that could see the biggest benefits, including the education and healthcare sectors.

Water Plus contacted and engaged customer sites, in its Be Wise On Water awareness raising approach - to increase water-saving and reduce impacts on the environment.

Each site taking part received a free water audit and water-saving kit installed on taps, with any smaller leaks found being isolated, or repaired.

Audits to identify areas for savings, installing water-saving kit and leak repairs were funded by the regional wholesaler United Utilities.

The results

Over 1 million litres saved daily

Expected overall daily saving for the collaborative project, so far, would be enough to fill a whopping 4.1 million cups of tea a day, with each holding 250ml. Overall this would also save £21,754, in wholesaler charges in just 5 days.*

Driving water savings in schools at-scale

800 primary and secondary schools amongst sites cutting water use - with schools seeing at least 290m3 (290,000 litres) of water saved a day in 2026, in the collaborative approach.

And the water saved in a month (during 20 school days) would be enough to supply 42,490 people with water, for a day, in a small UK town - showing how water efficiency can help with keeping supplies flowing in communities. Supplies based on 136.5 litres in daily water requirements per person.

Large scale delivery of water efficiency visits

4,660 visits completed overall, by end of March 2026, with at least 820m3 (820,000 litres of water saved a-day), tracked through meter readings in 2026.

Meter readings were taken before and after efficiency measures installed and action in the approach. Sites visited between April 2025 to March 2026.

Rapid cost savings through Water Efficiency

A total of £17,302 saving on wholesaler costs in 5 days where 821m3 saved each day.

Cost saving based on wholesaler water and wastewater charge of £4.22 per 1,000 litres of water from 25/26 FY wholesaler charges (measured as 1 cubic metre of water/1m3). Cost for sites using under 50 Megalitres.

* The saving is based on 1,031,081 litres of water saved a day (1,031 cubic metres of water a day). £21,754 saving in 5 days based on wholesaler water and wastewater charge of £4.22 per 1,000 litres of water from 25/26 FY wholesaler charges (measured as 1 cubic metre of water/1m3).
