United Utilities Home Audit Project


This report brings together findings from a trial carried out by United Utilities in 2006-2007 that investigated the effectiveness of water-efficient devices. 4,642 domestic properties in Warrington were sent an invitation. 393 took part in the audit and received a ‘water savers pack’, which included a basic shower timer and information on saving water. Further devices were installed where appropriate including water efficient showerheads, dual flush retrofit and save-a-flush cistern displacement devices. 67 % of 211 measured households were able to save water, on average 20.6 litres per property per day, which represents a reduction in water use of 6.8%.

Freshwater Availability and Use in the UK (2011)


The study identifies those industrial and commercial sectors and regions of the UK where water use is high, where there is scope for significant reductions in water use and where environmental pressures on water use are greatest. This study sought to complete a water mass balance for each region and sector in order that non-household sectors that are major consumers of water could be identified. All types of observations through CAMS (Catchment Abstraction Management Strategies), WEI (Water Exploitation Index) and other water stress indicators show that much of south-east England and East Anglia is currently, and will continue to be the most water-stressed area of the UK, although there are a number of very localised areas elsewhere which are already over-abstracted. These have been identified as short term priority locations.

Response to Welsh Assembly Government Consultation on Building Resilience to Climate Change (2011)

The consultation identifies productivity gains from more efficient use of water as potential benefit, and Waterwise wholeheartedly supports this - public sector organisations such as schools and hospitals can make significant savings on both their water and energy bills through wasting less in “domestic” processes such as taps, toilets, urinals and showers, as well as in cleaning processes.

Waterwise Consultation response for Draft EA drought plans (2011)

Waterwise praises this ambitious Environment Agency drought plan and is optimistic that, if implemented – and in combination with our suggestions – it will deliver an effective management and prevention of droughts while reconciling the interest of the environmental and water demand. Although, Waterwise is concerned whether the Environment Agency has adequate resources to implement such an ambitious plan (especially in the communications), considering the cuts that have taken place within their water resources team.

Waterwise Reponse to Consumer Council for Water Consultation on its Draft Forward Work Programme (2011)

Waterwise welcomes the emphasis in the Forward Work programme on the long-term legitimacy and sustainability of the water sector in England and Wales. CCWater’s role to date in providing customer feedback on existing and proposed water company mechanisms and frameworks has been very useful. However, Waterwise would like to see the Consumer Council for Water reach beyond reporting customer views, to taking an even more strategic approach to assessing what is in the interest of customers in the long-run – a clear aim of Ofwat’s regulatory processes.

Waterwise Response to BIS Call for Evidence on Principles for Economic Regulation (2011)

Waterwise is very supportive of the Coalition Government’s commitment to setting out principles for economic regulation across sectors. Many of the challenges – for example of climate change and population growth – are common across sectors, but because the regulatory framework for each sector has developed independently, these regulatory frameworks do not currently work together and on occasion work in conflict. This consultation and the resulting policy offers the opportunity to address such issues more strategically and deliver multiple outcomes more cost-effectively.

Review of the Water Resources Management Plan Process (2011)

Waterwise respond to Defra's call for a review of the first Water Resource Management Plan Process. Feedback includes a problematic lack of co-ordination between Ofwat's price review process and the WRMP process and a need for more standardised language and metrics.

Multi-Organisation Reponse to DECC Consultation on The role of appliances and consumer electronics in the CERT (2011)

This multi-organisation response was coordinated by Waterwise. Signatories to this response agree that CERT has been a useful mechanism to help the UK deliver its carbon emission reduction targets and stay within carbon budgets. It is recommended that the Coalition Government should review the existing function and scope of CERT within the extension period and in particular look at the role of non-insulation measures. We are of the opinion that the current scope of CERT should be maintained during the extension period, but with greater enforcement of existing regulation and amendments which maximise the potential for promoting joint water and energy programmes to ensure cost-effective CERT delivery.

Making the case for metering (2011)

This discussion paper was produced by Fairness on Tap, WWF-UK and Waterwise and makes the case for sustainably produced water that is affordable to everybody. It discusses three ways how this can be achieved: through a fair charging system which is supported by metering and social tariffs, good customer service, and water efficiency imperatives.

Evidence for Large-Scale Water Efficiency Phase II Final Report (2011)

In this final report of Phase II of the Evidence Base Project Waterwise analyses new data on the effectiveness of domestic and schools projects while providing a summary of lessons learnt from two 2010 reports on domestic water efficiency retrofitting and water efficiency retrofitting in schools. The reason for revisiting four of the nine trials originally analysed was to improve the industry’s understanding of the longevity of water savings in domestic water efficiency retrofitting. The mean length of additional monitoring period was 2.8 years, over which savings fell on average 20.6 % or by 5.4 litre/property/day.
